Emergence from Chapter 11	12 Months Ended

Emergence from Chapter 11	2.  Emergence from Chapter 11
	Overview
	On November 29, 2011 (the Petition Date), AMR Corporation (AMR, renamed American Airlines Group Inc., upon the closing of the Merger), its principal subsidiary, American, and certain of the Company’s other direct and indirect domestic subsidiaries (collectively, the Debtors), filed voluntary petitions for relief (the Chapter 11 Cases) under Chapter 11 of the United States Bankruptcy Code (the Bankruptcy Code) in the United States Bankruptcy Court for the Southern District of New York (the Bankruptcy Court). On October 21, 2013, the Bankruptcy Court entered an order (the Confirmation Order) approving and confirming the Debtors’ fourth amended joint plan of reorganization (as amended, the Plan).
	On December 9, 2013 (the Effective Date), the Debtors consummated their reorganization pursuant to the Plan, principally through the transactions contemplated by that certain Agreement and Plan of Merger (as amended, the Merger Agreement), dated as of February 13, 2013, by and among AMR, AMR Merger Sub, Inc. (Merger Sub) and US Airways Group, pursuant to which Merger Sub merged with and into US Airways Group (the Merger), with US Airways Group surviving as a wholly-owned subsidiary of the Company following the Merger. Pursuant to the Merger Agreement, each share of common stock, par value $0.01 per share, of US Airways Group was converted into the right to receive one share of AAG common stock, par value $0.01 per share (AAG Common Stock).
	From the Petition Date through the Effective Date, pursuant to automatic stay provisions under the Bankruptcy Code and orders granted by the Bankruptcy Court, all actions to enforce or otherwise effect repayment of liabilities preceding the Petition Date as well as all pending litigation against the Debtors generally were stayed. Following the Effective Date, actions to enforce or otherwise effect repayment of liabilities preceding the Petition Date generally have been permanently enjoined. Any unresolved claims will continue to be subject to the claims reconciliation process under the supervision of the U.S. Bankruptcy Court. However, certain pending litigation related to pre-petition liabilities may proceed in courts other than the U.S. Bankruptcy Court to the extent the parties to such litigation have obtained relief from the permanent injunction.
	Plan of Reorganization
	The Plan implements the Merger and incorporates a compromise and settlement of certain intercreditor and intercompany claim issues.
	Pursuant to the Plan, all shares of AMR common stock outstanding prior to the Effective Date were canceled. AAG’s Certificate of Incorporation, which was approved in connection with the Plan, authorizes the issuance of 1.75 billion new shares of AAG Common Stock and 200 million shares of AAG Series A Preferred Stock, par value $0.01 per share (AAG Series A Preferred Stock). Of the authorized AAG Series A Preferred Stock, approximately 168 million were designated “Series A Convertible Preferred Stock,” with a stated value of $25.00 per share, and issued in accordance with the Plan. AAG Common Stock is listed on the NASDAQ Global Select Market under the symbol “AAL” and began trading on December 9, 2013. AAG Series A Preferred Stock was listed on the NASDAQ Global Select Market under the symbol “AALCP” from December 9, 2013 until its final mandatory conversion on April 8, 2014. In addition, the 2013 Incentive Award Plan (the 2013 Plan) authorizes the grant of awards for the issuance of 40 million shares of AAG Common Stock plus any shares underlying awards granted under the 2013 Plan, or any pre-existing US Airways Group plan, that are forfeited, terminate or are cash settled (in whole or in part) without a payment being made in the form of shares. In addition, any shares that were available for issuance under the US Airways Group 2011 Incentive Award Plan (the 2011 Plan) as of the effective date of the Merger may be used for awards under the 2013 Plan; provided, that awards using such available shares shall not be made after the date awards or grants could have been made under 2011 Plan and shall only be made to individuals who were not providing services to AMR prior to the Merger.
	The Plan contains the following provisions relating to the treatment of pre-petition claims against the Debtors and other holders of allowed interests in the Debtors:
		•		all secured claims against the Debtors have been reinstated;
		•		allowed administrative claims, priority claims and convenience claims have been or will be paid in full in cash;
		•		other holders of allowed pre-petition unsecured claims, holders of allowed interests and certain employees of AMR received or will receive 72% of AAG Common Stock (on a fully converted basis) authorized to be issued pursuant to the Plan and in connection with the Merger under the following provisions:
		•		all creditors holding general unsecured claims against American that are guaranteed by AAG and general unsecured claims against AAG that are guaranteed by American (Double-Dip Unsecured Claims) were treated the same under the Plan. Holders of Double-Dip Unsecured Claims received, at the Effective Date, their recovery in shares of AAG Series A Preferred Stock with a stated amount equal to the allowed amount of their claims, including post-petition interest at the non-default rate;
		•		all creditors holding Single-Dip Unsecured Claims were treated the same regardless of whether the claim was asserted against the AAG Debtors, the American Debtors, or other Debtors. As used herein, “Single-Dip Unsecured Claims” means the general unsecured claims against the Debtors that were not guaranteed by any other Debtor, other than the claims of the Debtors’ labor unions representing mainline workers. Holders of Single-Dip Unsecured Claims received a portion of their recovery in shares of AAG Series A Preferred Stock at the Effective Date and their remaining recovery in shares of AAG Common Stock during the 120-day period after the Effective Date;
		•		holders of certain labor-related deemed claims and certain non-management, non-union employees as specified in the Plan received, at the Effective Date, the right to receive an allocation of shares of AAG Common Stock representing 23.6% of the total number of shares of AAG Common Stock ultimately distributed to holders of pre-petition general unsecured creditors against the Debtors. On the Effective Date, pursuant to the Plan, an initial allocation of approximately 39 million shares of AAG Common Stock was made related to these labor and employee groups, of which approximately 27 million shares were distributed on the Effective Date and approximately 13 million shares of which were withheld in connection with the Company making a cash payment of approximately $300 million for certain required withholding taxes;
		•		holders of allowed interests in AMR (primarily holders of AMR common stock existing immediately prior to the Effective Date) received, at the Effective Date, a distribution of approximately 26 million shares of AAG Common Stock representing 3.5% of the total number of shares of AAG Common Stock contemplated for issuance pursuant to the Plan and received an additional 267 million shares of AAG Common Stock during the 120-day period after the Effective Date; and
		•		holders of disputed claims at the Effective Date, to the extent such disputed claims become allowed Single-Dip Unsecured Claims after the Effective Date, are eligible to receive shares of AAG Common Stock held in reserve (the Disputed Claims Reserve), beginning 180 days after the Effective Date. Disputed claimholders that subsequently become holders of Single-Dip Unsecured Claims will receive, subject to the availability of sufficient shares in the Disputed Claims Reserve, the number of shares of AAG Common Stock that the disputed claimholder would have received had such claimholder been a holder of Single-Dip Unsecured Claims as of the Effective Date.
	The Plan contemplated the distribution of up to 756 million shares of AAG Common Stock, however this amount has been reduced by approximately 20 million shares because certain tax withholdings for employees were paid in cash as permitted under the Plan. In accordance with the Plan, the Company issued the remaining shares of AAG Common Stock over the 120-day distribution period, except for shares held in the Disputed Claims Reserve. In addition, pursuant to the Plan, approximately 197 million shares of AAG Common Stock were distributed to holders of outstanding shares of US Airways Group common stock.
	Pursuant to rulings of the Bankruptcy Court, the Plan established the Disputed Claims Reserve that was initially issued 30.4 million shares of AAG Common Stock reserved for issuance to disputed claimholders at the Effective Date that ultimately become holders of allowed Single-Dip Unsecured Claims (Single-Dip Equity Obligations) as well as to certain AMR labor groups and employees who received a deemed claim amount based upon a fixed percentage of the distributions to be made to general unsecured claimholders. On July 1, 2014 (the date 180 days after the Effective Date), approximately 2.9 million shares of AAG Common Stock held in the Disputed Claims Reserve were distributed to holders of allowed Single-Dip Unsecured Claims, to holders of certain labor-related deemed claims, and to holders of certain non-management, non-union employee deemed claims as specified in the Plan, and shares were withheld or sold on account of related tax obligations. In addition, on July 1, 2014, the Company repurchased 0.4 million shares of AAG Common Stock for an aggregate of $19 million from the Disputed Claims Reserve at the then prevailing market price in order to fund cash tax obligations resulting from distributions by the Disputed Claims Reserve. On November 4, 2014, approximately 0.7 million shares of AAG Common Stock held in the Disputed Claims Reserve were distributed to holders of allowed Single-Dip Unsecured Claims, to holders of certain labor-related deemed claims, and to holders of certain non-management, non-union employee deemed claims as specified in the Plan, and shares were withheld or sold on account of related tax obligations. In addition, on November 4, 2014, the Company repurchased less than 0.1 million shares of AAG Common Stock for an aggregate of $2 million from the Disputed Claims Reserve at the then prevailing market price in order to fund cash tax obligations resulting from distributions by the Disputed Claims Reserve. As of December 31, 2014, there were approximately 26.8 million shares of AAG Common Stock remaining in the Disputed Claims Reserve. As disputed claims are resolved, the claimants will receive distributions of shares from the Disputed Claims Reserve on the same basis as if such distributions had been made on or about the Effective Date. To the extent that any of the reserved shares remain undistributed upon resolution of all remaining disputed claims, such shares will not be returned to the Company but rather will be distributed to former AMR shareholders as of the Effective Date. The Company is not required to distribute additional shares above the limits contemplated by the Plan described above.
	In addition, from the Effective Date through December 31, 2014, the Company has made the following cash disbursements under the Plan:
		•		$385 million in cash to the pension plans in connection with missed contributions to the pension plans during the Chapter 11 Cases and interest and penalty interest thereon;
		•		$108 million in cash to holders in partial or full satisfaction of their claims, including to holders of administrative claims, and state and local priority tax claims;
		•		$196 million in cure payments to holders of secured debt; and
		•		Approximately $563 million for payroll and other taxes associated with equity distributions to employees and distributions from the Disputed Claims Reserve.
	Several parties have filed appeals seeking reconsideration of the Confirmation Order. See Note 15 for more information.
	The reconciliation process with respect to the remaining claims will take considerable time post-emergence. The Company’s estimate of the amounts of disputed claims that will ultimately become allowed Single-Dip Unsecured Claims are included in mandatorily convertible preferred stock and other bankruptcy settlement obligations on the Company’s consolidated balance sheet as of December 31, 2014. As these claims are resolved, or where better information becomes available and is evaluated, the Company will make adjustments to the liabilities recorded on the Company’s consolidated financial statements as appropriate. Any such adjustments could be material to the Company’s financial position or results of operations in any given period.
	Availability and Utilization of Net Operating Losses
	Upon emergence from bankruptcy, the Debtors experienced an “ownership change” as defined in Section 382 of the Internal Revenue Code of 1986, as amended (Section 382), which could potentially limit the ability to utilize certain tax attributes including the Debtors’ substantial net operating losses (NOLs). The general limitation rules for a debtor in a bankruptcy case are liberalized where the ownership change occurs upon emergence from bankruptcy. The Debtors elected to be covered by certain special rules for federal income tax purposes that permit approximately $9.0 billion of the federal NOL Carryforwards to be utilized without regard to the annual limitation generally imposed by Section 382. See Note 10 for additional information related to tax matters.
	Moreover, an ownership change subsequent to the Debtors’ emergence from bankruptcy may further limit or effectively eliminate the ability to utilize the Debtors’ NOL Carryforwards and other tax attributes. To reduce the risk of a potential adverse effect on the Debtors’ ability to utilize the NOL Carryforwards, AAG’s Certificate of Incorporation contains transfer restrictions applicable to certain substantial shareholders. Although the purpose of these transfer restrictions is to prevent an ownership change from occurring, there can be no assurance that an ownership change will not occur even with these transfer restrictions. A copy of AAG’s Certificate of Incorporation was attached as Exhibit 3.1 to a Current Report on Form 8-K filed by the Company with the SEC on December 9, 2013.
	Reorganization Items, Net
	Reorganization items refer to revenues, expenses (including professional fees), realized gains and losses and provisions for losses that are realized or incurred in the Chapter 11 Cases. The following table summarizes the components included in reorganization items, net on the consolidated statements of operations for the years ended December 31, 2013 and 2012 (in millions):
			December 31,
			2013		2012
	Pension and postretirement benefits		$	—	$	(66	)

	Fair value of conversion discount (4)			218		—
	Professional fees			199		229
	Other			180		95
	Total reorganization items, net		$	2,655	$	2,208
	-1	In exchange for employees’ contributions to the successful reorganization, including agreeing to reductions in pay and benefits, The Company agreed in the Plan to provide each employee group a deemed claim, which was used to provide a distribution of a portion of the equity of the reorganized entity to those employees. Each employee group received a deemed claim amount based upon a portion of the value of cost savings provided by that group through reductions to pay and benefits as well as through certain work rule changes. The total value of this deemed claim was approximately $1.7 billion.
	-2	Amounts include allowed claims (claims approved by the Bankruptcy Court) and estimated allowed claims relating to (i) the rejection or modification of financings related to aircraft and (ii) entry of orders treated as unsecured claims with respect to facility agreements supporting certain issuances of special facility revenue bonds. The Debtors recorded an estimated claim associated with the rejection or modification of a financing or facility agreement when the applicable motion was filed with the Bankruptcy Court to reject or modify such financing or facility agreement and the Debtors believed that it was probable the motion would be approved, and there was sufficient information to estimate the claim.
	-3	Pursuant to the Plan, the Debtors agreed to allow certain post-petition unsecured claims on obligations. As a result, during the year ended December 31, 2013, the Company recorded reorganization charges to adjust estimated allowed claim amounts previously recorded on rejected special facility revenue bonds of $180 million, allowed general unsecured claims related to the 1990 and 1994 series of special facility revenue bonds that financed certain improvements at John F. Kennedy International Airport (JFK), and rejected bonds that financed certain improvements at Chicago O’Hare International Airport (ORD), which are included in the table above.
	-4	The Plan allowed unsecured creditors receiving AAG Series A Preferred Stock a conversion discount of 3.5%. Accordingly, the Company recorded the fair value of such discount upon the confirmation of the Plan by the Bankruptcy Court.

	-3	Pursuant to the Plan, the Debtors agreed to allow certain post-petition unsecured claims on obligations. As a result, during the year ended December 31, 2013, American recorded reorganization charges to adjust estimated allowed claim amounts previously recorded on rejected special facility revenue bonds of $180 million, allowed general unsecured claims related to the 1990 and 1994 series of special facility revenue bonds that financed certain improvements at John F. Kennedy International Airport (JFK), and rejected bonds that financed certain improvements at Chicago O’Hare International Airport (ORD), which are included in the table above.
	-4	The Plan allowed unsecured creditors receiving AAG Series A Preferred Stock a conversion discount of 3.5%. Accordingly, American recorded the fair value of such discount upon the confirmation of the Plan by the Bankruptcy Court.

Mandatorily Convertible Preferred Stock and Other Bankruptcy Settlement Obligations	3.  Mandatorily Convertible Preferred Stock and Other Bankruptcy Settlement Obligations
	As of December 31, 2014 and 2013, the components of mandatorily convertible preferred stock and other bankruptcy settlement obligations on the consolidated balance sheets are as follows (in millions):
		December 31,
		2014		2013
	AAG Series A Preferred Stock	$	—	$	3,833
	Single-Dip Equity Obligations		248		1,246
	Labor-related deemed claim		77		849
	Total	$	325	$	5,928
	The AAG Series A Preferred Stock, while outstanding, voted and participated in accordance with the terms of the underlying Certificate of Designation. One quarter of the shares of AAG Series A Preferred Stock initially issued was mandatorily convertible on each of the 30th, 60th, 90th and 120th days after the Effective Date, subject to additional voluntary conversions. The initial stated value of each share of AAG Series A Preferred Stock was $25.00 and accrued dividends at 6.25% per annum, calculated daily, while outstanding. Additionally, AAG Series A Preferred Stock converted to AAG Common Stock based upon the volume weighted average price of the shares of AAG Common Stock on the five trading days immediately preceding the conversion date, at a 3.5% fixed discount, subject to a conversion price floor of $10.875 per share and a conversion price cap of $33.8080 per share, below or above which the conversion rate remains fixed. As of April 8, 2014, all shares of AAG Series A Preferred Stock had been converted into AAG Common Stock.
	The Single-Dip Equity Obligations, while outstanding, do not vote or participate in accordance with the terms of the Plan. These equity obligations, representing the amount of total Single-Dip Unsecured Claims not satisfied through the issuance of AAG Series A Preferred Stock at the Effective Date, represented an unconditional obligation to transfer a variable number of shares of AAG Common Stock based predominantly on a fixed monetary amount known at inception, and, as such, were not treated as equity, but rather as liabilities, until the 120th day after emergence, which was April 8, 2014. As of April 8, 2014, the Company has issued shares of AAG Common Stock to satisfy the obligation amount at emergence, plus accrued dividends of 12% per annum, calculated daily, through such date, based on the volume weighted average price of the shares of AAG Common Stock, at a 3.5% discount, as specified in the Plan. The amount of the remaining Single-Dip Equity Obligations at December 31, 2014 is the Company’s estimate of its obligation for disputed claims of $248 million and is calculated based on the fair value of the shares expected to be issued, measured as if the obligations were settled using the closing price of AAG Common Stock at December 31, 2014. Additional allowed claims will receive 30.7553 shares, subject to reduction for expenses of the Disputed Claims Reserve, including tax liabilities, for each $1,000 of allowed claims. For accounting purposes, the value of the shares expected to be issued is marked-to-market each period until issued. Accordingly, changes in the value of AAG Common Stock could result in future increases and decreases in this obligation.
	In exchange for employees’ contributions to the successful reorganization of the Company, including agreeing to reductions in pay and benefits, the Company agreed in the Plan to provide each employee group a deemed claim which was used to provide a distribution of a portion of the equity of the reorganized entity to those employees. Each employee group received a deemed claim amount based upon a fixed percentage of the distributions to be made to general unsecured claimholders. The fair value based on the expected number of shares to be distributed to satisfy this deemed claim, as adjusted, was approximately $1.5 billion. From the Effective Date through December 31, 2014, the Company has made distributions of $988 million in AAG Common Stock and paid approximately $553 million in cash to cover payroll and other taxes related to the equity distributions. As of December 31, 2014, the liability to certain AMR labor groups and employees of $77 million represents the estimated fair value of the remaining shares expected to be issued in satisfaction of such obligation, measured as if the obligation were settled using the closing price of AAG Common Stock at December 31, 2014. For accounting purposes, the value of the remaining shares expected to be issued to satisfy the labor claim is marked-to-market each period until issued. Accordingly, changes in the value of AAG Common Stock could result in future increases and decreases in this obligation.
	On July 1, 2014, approximately 2.9 million shares of AAG Common Stock held in the Disputed Claims Reserve were distributed to holders of allowed Single-Dip Unsecured Claims, to holders of certain labor-related deemed claims and to holders of certain non-management, non-union employee deemed claims as specified in the Plan, and shares were withheld or sold on account of related tax obligations. In addition, on November 4, 2014, approximately 0.7 million shares of AAG Common Stock held in the Disputed Claims Reserve were distributed to holders of allowed Single-Dip Unsecured Claims, to holders of certain labor-related deemed claims and to holders of certain non-management, non-union employee deemed claims as specified in the Plan, and shares were withheld or sold on account of related tax obligations.
	On February 10, 2015, approximately 0.8 million shares of AAG Common Stock held in the Disputed Claims Reserve were distributed to holders of allowed Single-Dip Unsecured Claims, to holders of certain labor-related deemed claims and to holders of certain non-management, non-union employee deemed claims as specified in the Plan, and shares were withheld or sold on account of related tax obligations.

Business Combinations [Abstract]
Merger and Related Matters	4.  Merger and Related Matters
	Description of Transaction
	As previously discussed in Note 2, on the Effective Date, the Debtors consummated their reorganization and the Merger pursuant to the Plan. The Merger has been accounted for as a business acquisition using the acquisition method of accounting in accordance with ASC 805, “Business Combinations,” with AAG considered the acquirer of US Airways Group. The acquisition method of accounting requires, among other things, that assets acquired and liabilities assumed be recognized on the balance sheet at their fair values as of the acquisition date. The acquisition values have also been reflected in US Airways Group’s separate-entity financial statements as of December 9, 2013. The excess of the purchase price over the net fair value of assets and liabilities acquired was recorded as goodwill. Goodwill is not amortized, but is tested for impairment at least annually.
	Slot Divestitures
	As a stipulation for the Merger to be approved by the Department of Justice (DOJ), the Company was required to divest certain airport take-off and landing rights (Slots) at LaGuardia Airport and Ronald Reagan Washington National Airport (DCA). As of December 31, 2013, the DCA Slots to be divested were recorded as assets held for sale and were included in prepaid expenses and other on the consolidated balance sheet. In 2014, the Company divested the required DCA Slots and received $307 million in cash as well as 24 Slots at JFK. The Company recognized a net gain of $309 million related to these divestitures, which has been included in special items, net in the consolidated statement of operations. In 2013, the Company recognized a gain of $67 million related to the sale of the LaGuardia Airport Slots, which has been included in special items, net in the consolidated statement of operations.
	In 2013, the European Commission cleared under the EU Merger Regulation the proposed merger between US Airways and American. As a consequence of the merger clearance process in the EU, the Company was required to make available one pair of London Heathrow Slots for use by another carrier between London and Philadelphia, which the acquiring carrier can deploy on another Heathrow city pair after operating the Slots on London-Philadelphia for a period of not less than three consecutive years. In addition, along with the Company’s joint business agreement (JBA) partners, the Company was required to make available for an initial period of up to seven years one pair of Heathrow Slots for service between London and Miami that may be operated via an intermediate point. In connection with these requirements and upon making these slots available, in 2014, the Company recorded a $43 million non-cash charge, which has been included in special items, net in the consolidated statement of operations.
	Fair Value of Consideration Transferred
	The fair value of the consideration transferred, or the purchase price, was derived as described below based on the outstanding shares of US Airways Group common stock at December 9, 2013, the exchange ratio of one share of AAG Common Stock for each share of US Airways Group common stock, and a price per share of AAG Common Stock of $22.55, which represented the closing price of US Airways Group common stock on December 6, 2013, the last day such shares traded on the New York Stock Exchange. US Airways Group equity awards outstanding at the close of the Merger converted into equity awards with respect to AAG Common Stock. Vested equity awards held by employees of US Airways Group are considered part of the purchase price.
		(In millions except per share data)
	Outstanding shares of US Airways Group Common Stock at December 9, 2013 exchanged		197.4
	Exchange ratio		1
	Assumed shares of AAG Common Stock		197.4

	Fair value of AAG Common Stock issued	$	4,451
	Fair value of AAG equity awards issued in exchange for outstanding US Airways Group equity awards	$	141
	Total purchase price	$	4,592
	Allocation of Consideration Transferred
	The Merger has been accounted for using the acquisition method of accounting in accordance with ASC 805, “Business Combinations” (ASC 805), with AAG treated as the acquirer of US Airways Group for accounting purposes. The acquisition method of accounting requires, among other things, that assets acquired and liabilities assumed be recognized on the balance sheet at their fair values as of the acquisition date. The excess of the purchase price over the net fair value of assets acquired and liabilities assumed was recorded as goodwill. Goodwill is not amortized, but is tested for impairment at least annually.
		(In millions)
	Cash	$	206
	Short-term investments		3,517
	Other current assets		1,459
	Operating property and equipment		5,536
	Goodwill		4,091
	Identifiable intangibles		1,501
	Other noncurrent assets		123
	Long-term debt and capital leases, including current portion		(6,026	)
	Air traffic liability		(1,417	)
	Frequent flyer liability		(1,256	)
	Other liabilities assumed		(3,142	)
	Total purchase price	$	4,592
	The fair values of the assets acquired and liabilities assumed were determined using the market, income and cost approaches. The fair value measurements were primarily based on significant inputs that are not observable in the market, other than certain long-term debt assumed in the Merger. The market approach, which indicates value for a subject asset based on available market pricing for comparable assets, was utilized to estimate the fair value of US Airways’ aircraft and operating leases. The market approach included prices and other relevant information generated by market transactions involving comparable assets, as well as pricing guides and other sources. The Company considered the current market for the aircraft, the maintenance condition of the aircraft and the expected proceeds from the sale of the assets, among other factors. The Company also utilized the market approach to value certain intangible assets such as airport take-off and landing slots when sufficient market information was available. The income approach was primarily used to value intangible assets, including customer relationships, marketing agreements, certain international route authorities, and the US Airways logo and tradenames. The income approach indicates value for a subject asset based on the present value of cash flows projected to be generated by the asset. Projected cash flows are discounted at a required market rate of return that reflects the relative risk of achieving the cash flows and the time value of money. The cost approach, which estimates value by determining the current cost of replacing an asset with another of equivalent economic utility, was used, as appropriate, for certain assets for which the market and income approaches could not be applied due to the nature of the asset. The cost to replace a given asset reflects the estimated reproduction or replacement cost for the asset, less an allowance for loss in value due to depreciation. The fair value of US Airways’ Dividend Miles frequent flyer program liability was determined based on the equivalent ticket value of outstanding miles which were expected to be redeemed at December 9, 2013. The equivalent ticket value contemplates purchased tickets that have similar restrictions as frequent traveler awards.
	Pro-forma Impact of the Merger
	The Company’s unaudited pro-forma results presented below include the effects of the Merger with US Airways Group as if it had been consummated as of January 1, 2012. The pro-forma results include the depreciation and amortization associated with the acquired tangible and intangible assets, lease and debt fair value adjustments, the elimination of any deferred gains or losses, adjustments relating to reflecting the fair value of the frequent flyer liability and the impact of income changes on profit sharing expense, among others. In addition, the pro-forma results below reflect the impact of higher wage rates related to memorandums of understanding with US Airways’ pilots and all labor groups of the Company that became effective upon closing of the Merger as well as the elimination of the Company’s reorganization items, net and Merger transition costs. However, the pro-forma results do not include any anticipated synergies or other expected benefits of the Merger. Accordingly, the unaudited pro-forma financial information below is not necessarily indicative of either future results of operations or results that might have been achieved had the acquisition been consummated as of January 1, 2012.

Basis_of_Presentation_and_Summ

Basis of Presentation and Summary of Significant Accounting Policies	12 Months Ended
	Dec. 31, 2014
Basis of Presentation and Summary of Significant Accounting Policies	5.  Basis of Presentation and Summary of Significant Accounting Policies
	(a) Basis of Presentation
	The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. As a result of the Merger, the consolidated financial statements presented include the results of AMR and its wholly-owned subsidiaries, American and Envoy, for periods ended prior to December 9, 2013 and consolidated results of AAG, which includes American, Envoy and US Airways Group, for periods ending on or after December 9, 2013. Accordingly, the consolidated financial statement for the year ended December 31, 2013 includes the accounts of US Airways Group for the 23 days ended December 31, 2013. All significant intercompany transactions have been eliminated.
	The preparation of financial statements in accordance with accounting principles generally accepted in the United States (GAAP) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The most significant areas of judgment relate to passenger revenue recognition, impairment of goodwill, impairment of long-lived and intangible assets, the frequent traveler programs, pensions and retiree medical and other benefits and the deferred tax asset valuation allowance.
	(b) Chapter 11 Matters
	In accordance with GAAP, the Debtors (as defined in Note 2 above) applied ASC 852 “Reorganizations” (ASC 852) in preparing the consolidated financial statements for periods subsequent to the Chapter 11 Cases (as defined in Note 2 above). ASC 852 requires that the financial statements distinguish transactions and events that are directly associated with the reorganization from the ongoing operations of the business. Accordingly, certain revenues, expenses (including professional fees), realized gains and losses and provisions for losses that are realized or incurred in the Chapter 11 Cases for the 2013 and 2012 period are presented in reorganization items, net on the accompanying consolidated statements of operations.
	(c) Restricted Cash and Short-term Investments
	The Company has restricted cash and short-term investments related primarily to collateral held to support projected workers’ compensation obligations and funds held for certain tax obligations.
	(d) Aircraft Fuel, Spare Parts, and Supplies, Net
	Aircraft fuel, spare parts, and supplies, net are recorded at net realizable value based on average costs. These items are expensed when used. An allowance for obsolescence is provided for aircraft spare parts and supplies.
	(e) Operating Property and Equipment
	Operating property and equipment are recorded at cost. Interest expense related to the acquisition of certain property and equipment, including aircraft purchase deposits, is capitalized as an additional cost of the asset. Interest capitalized for the years ended December 31, 2014, 2013 and 2012 was $61 million, $47 million and $50 million, respectively. Property and equipment is depreciated and amortized to residual values over the estimated useful lives or the lease term, whichever is less, using the straight-line method. Costs of major improvements that enhance the usefulness of the asset are capitalized and depreciated over the estimated useful life of the asset or the modifications, whichever is less. The depreciable lives used for the principal depreciable asset classifications are:
	Principal Depreciable Asset Classification		Depreciable Life
	Jet aircraft and engines		16 - 30 years
	Other regional aircraft and engines		25 years
	Major rotable parts, avionics and assemblies		Fleet end date
	Improvements to leased flight equipment		Lesser of asset/leasehold improvement or lease end date
	Buildings and improvements		Lesser of 5 - 30 years or lease term
	Furniture, fixtures and other equipment		3 - 10 years: ranges from computer hardware to furniture
	Capitalized software		Lesser of 5 years or lease term
	Residual values for aircraft, engines, major rotable parts, avionics and assemblies are generally 5% to 10%.
	Equipment and property under capital leases are amortized over the term of the leases or, in the case of certain aircraft, over their expected useful lives. Lease terms vary but are generally 16 to 30 years for aircraft and three to 30 years for other leased equipment and property.
	The Company records impairment charges on long-lived assets used in operations when events and circumstances indicate that the assets may be impaired. An asset or group of assets is considered impaired when the undiscounted cash flows estimated to be generated by the asset are less than the carrying amount of the asset and the net book value of the asset exceeds its estimated fair value. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less cost to sell.
	(f) Income Taxes
	Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. A valuation allowance is established, if necessary, for the amount of any tax benefits that, based on available evidence, are not expected to be realized.
	(g) Goodwill
	Goodwill represents the excess of the purchase price over the fair value of the net assets acquired and liabilities assumed. Goodwill is not amortized but tested for impairment annually or more frequently if events or circumstances indicate. The Company has one consolidated reporting unit.
	Goodwill is measured for impairment by initially performing a qualitative screen and, if necessary, then comparing the fair value of the reporting unit to its carrying value, including goodwill. If the fair value of the reporting unit is less than the carrying value, a second step is performed to determine the implied fair value of goodwill. If the implied fair value of goodwill is lower than its carrying value, an impairment charge equal to the difference is recorded. Based upon the Company’s annual testing, there was no goodwill impairment in 2014.
	(h) Other Intangibles, Net
	Intangible assets consist primarily of airport take-off and landing rights (Slots), customer relationships, marketing agreements, international Slots and route authorities, gate leasehold rights and tradenames. Intangible assets with estimable useful lives are amortized over their respective estimated useful lives to their estimated residual values and reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable.
	The following table provides information relating to the Company’s amortizable intangible assets as of December 31, 2014 and 2013 (in millions):
			December 31,
			2014			2013
	Airport Slots		$	365		$	332
	Customer relationships			300			300
	Marketing agreements			105			105
	Tradenames			35			35
	Airport gate leasehold rights			138			155
	Accumulated amortization			(447	)		(373	)
	Total		$	496		$	554
	Airport operating and gate lease rights are being amortized on a straight-line basis over 25 years to a zero residual value. The customer relationships, marketing agreements and tradenames were identified as intangible assets subject to amortization and are amortized on a straight-line basis over approximately nine years, 30 years and 15 months, respectively.
	The Company recorded amortization expense related to these intangible assets of approximately $81 million, $20 million and $25 million for the years ended December 31, 2014, 2013 and 2012, respectively. The Company expects to record annual amortization expense for the aforementioned definite-life intangible assets as follows (in millions):
	2015		$	56
	2016			50
	2017			46
	2018			42
	2019			42
	2020 and thereafter			260
	Total		$	496
	The Company’s indefinite-lived assets include certain international Slots and route authorities and domestic airport take-off and landing slots. Indefinite-lived assets are not amortized but instead are reviewed for impairment annually and more frequently if events or circumstances indicate that the asset may be impaired. As of December 31, 2014 and 2013, the Company had $1.7 billion and $1.8 billion, respectively, of indefinite-lived intangible assets on its consolidated balance sheets.
	The Company’s indefinite-lived intangible assets are reviewed for impairment by initially performing a qualitative screen to determine whether the Company believes it is more likely than not that an asset has been impaired. If the Company believes an impairment has occurred, the Company then evaluates for impairment by comparing the estimated fair value of assets to the carrying value. An impairment charge is recognized if the asset’s estimated fair value is less than its carrying value. Based upon the Company’s annual testing, there was no indefinite-lived intangible asset impairment in 2014.
	(i) Frequent Flyer Programs
	AAG currently operates two frequent traveler programs, American’s AAdvantage and US Airways’ Dividend Miles. These programs award mileage credits to passengers who fly on American, US Airways and oneworld carriers, as well as certain other partner airlines that participate in the programs. Mileage credits can also be earned through purchases from other non-airline partners that participate in the Company’s respective loyalty programs. Mileage credits can be redeemed for travel on American, US Airways or other participating partner airlines, in which case the Company pays a fee.
	The Company uses the incremental cost method to account for the portion of the Company’s frequent flyer liability incurred when AAdvantage and Dividend Miles members earn mileage credits by flying on American, US Airways or its regional affiliates. The Company has an obligation to provide future travel when these mileage credits are redeemed and therefore has recorded a liability for mileage credits outstanding.
	The incremental cost liability includes all mileage credits that are expected to be redeemed, including mileage credits earned by members whose mileage account balances have not yet reached the minimum mileage credit level required to redeem an award. Additionally, outstanding mileage credits are subject to expiration if unused. In calculating the liability, the Company estimates how many mileage credits will never be redeemed for travel and excludes those mileage credits from the estimate of the liability. Estimates are also made for the number of miles that will be used per award redemption and the number of travel awards that will be redeemed on partner airlines. These estimates are based on historical program experience as well as consideration of enacted program changes, as applicable. Changes in the liability resulting from members earning additional mileage credits or changes in estimates are recorded in the statement of operations as a part of passenger revenue.
	The liability for outstanding mileage credits is valued based on the estimated incremental cost of carrying one additional passenger. Incremental cost primarily includes unit costs incurred for fuel, food, and insurance as well as fees incurred when travel awards are redeemed on partner airlines. No profit or overhead margin is included in the accrual of incremental cost. These estimates are generally updated based upon the Company’s 12-month historical average of such costs.
	The Company applied the acquisition method of accounting in connection with the Merger and therefore recorded the liability for outstanding US Airways mileage credits at fair value. As of December 31, 2014 and 2013, the liability for outstanding mileage credits expected to be redeemed for future travel awards for US Airways under the Dividend Miles program was $638 million and $932 million and is included on the consolidated balance sheets within frequent flyer liability. This liability will be reduced as miles are redeemed and new miles earned will be recorded as a liability based on the incremental cost method discussed above.
	As of December 31, 2014 and 2013 the liability for outstanding mileage credits for the AAdvantage program was $647 million and $580 million, respectively, and is included on the consolidated balance sheets within frequent flyer liability.
	American and US Airways also sell frequent flyer program mileage credits to participating airline partners and non-airline business partners. Sales of mileage credits to business partners is comprised of two components, transportation and marketing. Historically, American and US Airways have used the residual method of accounting to determine the values of each component as there had not been a material modification to any significant agreements since the adoption of Accounting Standards Update (ASU) No. 2009-13, “Revenue Recognition (Topic 605) – Multiple-Deliverable Revenue Arrangements” on January 1, 2011.
	In 2013, American and Citibank amended their AAdvantage co-branded credit card agreement, which resulted in a material modification of the terms of the arrangement. Also, in connection with the acquisition of US Airways on December 9, 2013, a material modification occurred on all of US Airways’ agreements in connection with the Merger. Therefore, subsequent to the amendments of these arrangements, AAG applied the relative selling price method to determine the values of each deliverable. Under the relative selling price approach, American and US Airways identified five revenue elements for the co-branded credit card agreement with Citibank and Dividend Miles co-branded credit card agreement with Barclays: the transportation component; use of the American and US Airways’ brand including access to frequent flyer member lists; advertising; lounge access; and baggage services (together excluding “the transportation component,” the “marketing component”).
	The transportation component represents the estimated selling price of future travel awards and is determined using historical transaction information, including information related to customer redemption patterns. The transportation component is deferred based on its relative selling price and amortized into passenger revenue on a straight-line basis over the period in which the mileage credits are expected to be redeemed for travel.
	The marketing component represents services provided to the Company’s business partners and relates primarily to the use of American’s and US Airways’ logo and tradenames along with access to customers lists of AAdvantage and Dividend Miles members. The marketing services are provided periodically, but no less than monthly. Accordingly, the marketing component is considered earned and recognized in other revenues in the period of the mileage sale.
	Upon application of the relative selling price method in 2013 for American’s Citibank modification, American reduced its travel component liability and recorded other revenue of approximately $31 million. As a result of the change in the marketing component value when the relative selling price method is applied, American and US Airways now defer less revenue per mile sold. For American’s agreements where there has not been a material modification, it continues to apply the residual method.
	As of December 31, 2014 and 2013, the Company had $1.5 billion in deferred revenue from the sale of mileage credits (recorded as frequent flyer liability on the consolidated balance sheets). For the years ended December 31, 2014, 2013 and 2012, the marketing component of mileage sales recognized at the time of sale in other revenues was approximately $1.4 billion, $834 million and $725 million, respectively.
(j) Passenger Revenue
Passenger ticket sales are initially recorded as a component of air traffic liability. Revenue derived from ticket sales is recognized at the time service is provided. However, due to various factors, including the complex pricing structure and interline agreements throughout the industry, certain amounts are recognized in revenue using estimates regarding both the timing of the revenue recognition and the amount of revenue to be recognized, including breakage. These estimates are generally based upon the evaluation of historical trends, including the use of regression analysis and other methods to model the outcome of future events based on the Company’s historical experience, and are recorded at the scheduled time of departure.
The Company purchases capacity, or ASMs, generated by the Company’s wholly-owned regional air carriers and the capacity of Air Wisconsin Airlines Corporation (Air Wisconsin), Republic Airways Holdings’ subsidiaries Republic Airlines (Republic) and Chautauqua Airlines (Chautauqua), Mesa Airlines, Inc. (Mesa), and SkyWest Airlines, Inc.’s subsidiaries Sky West Airlines (SkyWest) and ExpressJet Airlines (ExpressJet) in certain markets. The Company’s wholly-owned regional air carriers and Air Wisconsin, Chautauqua, ExpressJet, Republic, Mesa, and SkyWest operate regional aircraft in these markets as part of either American Eagle carriers or US Airways Express. The Company classifies revenues generated from transportation on these carriers as regional passenger revenues. Liabilities related to tickets sold by the Company for travel on these air carriers are also included in the Company’s air traffic liability and are subsequently relieved in the same manner as described above.
Various taxes and fees assessed on the sale of tickets to end customers are collected by the Company as an agent and remitted to taxing authorities. These taxes and fees have been presented on a net basis in the accompanying consolidated statements of operations and recorded as a liability until remitted to the appropriate taxing authority.
(k) Maintenance, Materials and Repairs
Maintenance and repair costs for owned and leased flight equipment are charged to operating expense as incurred, except costs incurred for maintenance and repair under flight hour maintenance contract agreements, which are accrued based on contractual terms when an obligation exists.
(l) Selling Expenses
Selling expenses include commissions, credit card fees, computerized reservations systems fees and advertising. Advertising expenses are expensed as incurred. Advertising expense was $100 million, $166 million and $153 million for the years ended December 31, 2014, 2013 and 2012, respectively.
(m) Share-based Compensation
The Company accounts for its share-based compensation expense based on the fair value of the stock award at the time of grant, which is recognized ratably over the vesting period of the stock award. The fair value of stock options and stock appreciation rights is estimated using a Black-Scholes option pricing model. The fair value of restricted stock units is based on the market price of the underlying shares of common stock on the date of grant. See Note 18 for further discussion of share-based compensation.
(n) Deferred Gains and Credits, Net

American Airlines, Inc. [Member]
Basis of Presentation and Summary of Significant Accounting Policies	4.  Basis of Presentation and Summary of Significant Accounting Policies
	(a) Basis of Presentation
	The consolidated financial statements as of and for the years ended December 31, 2014, 2013 and 2012 include the accounts of American. American is a wholly-owned subsidiary of American Airlines Group Inc. (AAG). All significant intercompany transactions have been eliminated.
	The preparation of financial statements in accordance with accounting principles generally accepted in the United States (GAAP) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The most significant areas of judgment relate to passenger revenue recognition, impairment of long-lived and intangible assets, the frequent traveler program, pensions and retiree medical and other benefits and the deferred tax asset valuation allowance.
	(b) Chapter 11 Matters
	In accordance with GAAP, the Debtors (as defined in Note 2 above) applied ASC 852 “Reorganizations” (ASC 852) in preparing the consolidated financial statements for periods subsequent to the Chapter 11 Cases (as defined in Note 2 above). ASC 852 requires that the financial statements distinguish transactions and events that are directly associated with the reorganization from the ongoing operations of the business. Accordingly, certain revenues, expenses (including professional fees), realized gains and losses and provisions for losses that are realized or incurred in the Chapter 11 Cases for the 2013 and 2012 period are presented in reorganization items, net on the accompanying consolidated statements of operations.
	(c) Restricted Cash and Short-term Investments
	American has restricted cash and short-term investments related primarily to collateral held to support projected workers’ compensation obligations and funds held for certain tax obligations.
	(d) Aircraft Fuel, Spare Parts, and Supplies, Net
	Aircraft fuel, spare parts, and supplies, net are recorded at net realizable value based on average costs. These items are expensed when used. An allowance for obsolescence is provided for aircraft spare parts and supplies.
	(e) Operating Property and Equipment
	Operating property and equipment are recorded at cost. Interest expense related to the acquisition of certain property and equipment, including aircraft purchase deposits, is capitalized as an additional cost of the asset. Interest capitalized for the years ended December 31, 2014, 2013 and 2012 was $53 million, $47 million and $50 million, respectively. Property and equipment is depreciated and amortized to residual values over the estimated useful lives or the lease term, whichever is less, using the straight-line method. Costs of major improvements that enhance the usefulness of the asset are capitalized and depreciated over the estimated useful life of the asset or the modifications, whichever is less. The depreciable lives used for the principal depreciable asset classifications are:
	Principal Depreciable Asset Classification		Depreciable Life
	Jet aircraft and engines		16—30 years
	Other regional aircraft and engines		25 years
	Major rotable parts, avionics and assemblies		Fleet end date
	Improvements to leased flight equipment		Lesser of asset/leasehold improvement or lease end date
	Buildings and improvements		Lesser of 5—30 years or lease term
	Furniture, fixtures and other equipment		3—10 years: ranges from computer hardware to furniture
	Capitalized software		Lesser of 5 years or lease term
	Residual values for aircraft, engines, major rotable parts, avionics and assemblies are generally 5% to 10%.
	Equipment and property under capital leases are amortized over the term of the leases or, in the case of certain aircraft, over their expected useful lives. Lease terms vary but are generally 16 to 30 years for aircraft and three to 30 years for other leased equipment and property.
	American records impairment charges on long-lived assets used in operations when events and circumstances indicate that the assets may be impaired. An asset or group of assets is considered impaired when the undiscounted cash flows estimated to be generated by the asset are less than the carrying amount of the asset and the net book value of the asset exceeds its estimated fair value. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less cost to sell.
	(f) Income Taxes
	Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. A valuation allowance is established, if necessary, for the amount of any tax benefits that, based on available evidence, are not expected to be realized.
	(g) Other Intangibles, Net
	Intangible assets consist primarily of airport take-off and landing rights (Slots), international Slots and route authorities and gate leasehold rights. Intangible assets with estimable useful lives are amortized over their respective estimated useful lives to their estimated residual values and reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable.
	The following table provides information relating to American’s amortizable intangible assets as of December 31, 2014 and 2013 (in millions):
			December 31,
			2014			2013
	Airport Slots		$	310		$	277
	Airport gate leasehold rights			138			155
	Accumulated amortization			(376	)		(375	)
	Total		$	72		$	57
	Airport operating and gate lease rights are amortized on a straight-line basis over 25 years to a zero residual value.
	American recorded amortization expense related to these intangible assets of approximately $14 million, $18 million and $25 million for the years ended December 31, 2014, 2013 and 2012, respectively. American expects to record annual amortization expense for the aforementioned definite-life intangible assets as follows (in millions):
	2015		$	12
	2016			11
	2017			7
	2018			3
	2019			3
	2020 and thereafter			36
	Total		$	72
	American’s indefinite-lived assets include certain international route authorities and domestic airport take-off and landing slots. Indefinite-lived assets are not amortized but instead are reviewed for impairment annually and more frequently if events or circumstances indicate that the asset may be impaired. As of December 31, 2014 and 2013, American had $743 million and $755 million, respectively, of indefinite-lived intangible assets on its consolidated balance sheets.
	American’s indefinite-lived intangible assets are reviewed for impairment by initially performing a qualitative screen to determine whether American believes it is more likely than not that an asset has been impaired. If American believes an impairment has occurred, American then evaluates for impairment by comparing the estimated fair value of assets to the carrying value. An impairment charge is recognized if the asset’s estimated fair value is less than its carrying value. Based upon American’s annual testing, there was no indefinite-lived intangible asset impairment in 2014.
	Slot Divestitures
	As a stipulation for the Merger to be approved by the Department of Justice (DOJ), American was required to divest certain Slots at LaGuardia Airport and Ronald Reagan Washington National Airport (DCA). As of December 31, 2013, the DCA Slots to be divested were recorded as assets held for sale and were included in prepaid expenses and other on the consolidated balance sheet. In 2014, American divested the required DCA Slots and received $299 million in cash as well as 24 Slots at JFK. American recognized a gain of $305 million related to these divestitures, which has been included in special items, net in the consolidated statement of operations. In 2013, American recognized a gain of $67 million related to the sale of the LaGuardia Airport Slots, which has been included in special items, net in the consolidated statement of operations.
	In 2013, the European Commission cleared under the EU Merger Regulation the proposed merger between US Airways and American. As a consequence of the merger clearance process in the EU, American was required to make available one pair of London Heathrow Slots for use by another carrier between London and Philadelphia, which the acquiring carrier can deploy on another Heathrow city pair after operating the Slots on London-Philadelphia for a period of not less than three consecutive years. In addition, along with American’s joint business agreement (JBA) partners, American was required to make available for an initial period of up to seven years one pair of Heathrow Slots for service between London and Miami that may be operated via an intermediate point. In connection with these requirements and upon making these slots available, in 2014, American recorded a $43 million non-cash charge, which has been included in special items, net in the consolidated statement of operations.
	(h) Frequent Flyer Program
	American currently operates the AAdvantage frequent flyer program. This program awards mileage credits to passengers who fly on American and oneworld carriers, as well as certain other partner airlines that participate in the programs. Mileage credits can also be earned through purchases from other non-airline partners that participate in American’s loyalty program. Mileage credits can be redeemed for travel on American, US Airways or other participating partner airlines, in which case American pays a fee.
	American uses the incremental cost method to account for the portion of American’s frequent flyer liability incurred when AAdvantage members earn mileage credits by flying on American, US Airways or its regional affiliates. American has an obligation to provide future travel when these mileage credits are redeemed and therefore has recorded a liability for mileage credits outstanding.
	The incremental cost liability includes all mileage credits that are expected to be redeemed, including mileage credits earned by members whose mileage account balances have not yet reached the minimum mileage credit level required to redeem an award. Additionally, outstanding mileage credits are subject to expiration if unused. In calculating the liability, American estimates how many mileage credits will never be redeemed for travel and excludes those mileage credits from the estimate of the liability. Estimates are also made for the number of miles that will be used per award redemption and the number of travel awards that will be redeemed on partner airlines. These estimates are based on historical program experience as well as consideration of enacted program changes, as applicable. Changes in the liability resulting from members earning additional mileage credits or changes in estimates are recorded in the statement of operations as a part of passenger revenue.
	The liability for outstanding mileage credits is valued based on the estimated incremental cost of carrying one additional passenger. Incremental cost primarily includes unit costs incurred for fuel, food, and insurance as well as fees incurred when travel awards are redeemed on partner airlines. No profit or overhead margin is included in the accrual of incremental cost. These estimates are generally updated based upon American’s 12-month historical average of such costs.
	As of December 31, 2014 and 2013 the liability for outstanding mileage credits for the AAdvantage program was $647 million and $580 million, respectively, and is included on the consolidated balance sheets within frequent flyer liability.
	American also sells frequent flyer program mileage credits to participating airline partners and non-airline business partners. Sales of mileage credits to business partners is comprised of two components, transportation and marketing. Historically, American has used the residual method of accounting to determine the values of each component as there had not been a material modification to any significant agreements since the adoption of Accounting Standards Update (ASU) No. 2009-13, “Revenue Recognition (Topic 605) – Multiple-Deliverable Revenue Arrangements” on January 1, 2011.
	In 2013, American and Citibank amended their current AAdvantage co-branded credit card agreement which resulted in a material modification of the terms of the arrangement. Therefore, subsequent to the amendment of the arrangement, American applied the relative selling price method to determine the values of each deliverable. Under the relative selling price approach, American identified five revenue elements for the co-branded credit card agreements with Citibank: the transportation component; use of American’s brand including access to frequent flyer member lists; advertising; lounge access; and baggage services (together excluding “the transportation component,” the “marketing component”).
	The transportation component represents the estimated selling price of future travel awards and is determined using historical transaction information, including information related to customer redemption patterns. The transportation component is deferred based on its relative selling price and amortized into passenger revenue on a straight-line basis over the period in which the mileage credits are expected to be redeemed for travel.
	The marketing component represents services provided to American’s business partners and relates primarily to the use of American’s logo and tradename along with access to customers lists of AAdvantage members. The marketing services are provided periodically, but no less than monthly. Accordingly, the marketing component is considered earned and recognized in other revenues in the period of the mileage sale.
	Upon application of the relative selling price method in 2013 for American’s Citibank modification, American reduced its travel component liability and recorded other revenue of approximately $31 million. As a result of the change in the marketing component value when the relative selling price method is applied, American now defers less revenue per mile sold. For American’s agreements where there has not been a material modification, it continues to apply the residual method.
	As of December 31, 2014 and 2013, American had $1.2 billion in deferred revenue from the sale of mileage credits (recorded as frequent flyer liability on the consolidated balance sheets). For the years ended December 31, 2014, 2013 and 2012, the marketing component of mileage sales recognized at the time of sale in other revenues was approximately $1.1 billion, $816 million and $725 million, respectively.
	(i) Passenger Revenue
	Passenger ticket sales are initially recorded as a component of air traffic liability. Revenue derived from ticket sales is recognized at the time service is provided. However, due to various factors, including the complex pricing structure and interline agreements throughout the industry, certain amounts are recognized in revenue using estimates regarding both the timing of the revenue recognition and the amount of revenue to be recognized, including breakage. These estimates are generally based upon the evaluation of historical trends, including the use of regression analysis and other methods to model the outcome of future events based on American’s historical experience, and are recorded at the scheduled time of departure.
	American purchases capacity, or ASMs, generated by AAG’s wholly-owned regional air carrier and the capacity of Republic Airways Holdings’ subsidiaries Republic Airlines (Republic) and Chautauqua Airlines (Chautauqua), and SkyWest Airlines, Inc.‘s subsidiaries Sky West Airlines (SkyWest) and ExpressJet Airlines (ExpressJet) in certain markets. AAG’s wholly-owned regional air carrier and Chautauqua, ExpressJet, Republic, and SkyWest operate regional aircraft in these markets as part of American Eagle carriers. American classifies revenues generated from transportation on these carriers as regional passenger revenues. Liabilities related to tickets sold by American for travel on these air carriers are also included in American’s air traffic liability and are subsequently relieved in the same manner as described above.
	Various taxes and fees assessed on the sale of tickets to end customers are collected by American as an agent and remitted to taxing authorities. These taxes and fees have been presented on a net basis in the accompanying consolidated statements of operations and recorded as a liability until remitted to the appropriate taxing authority.
(j) Maintenance, Materials and Repairs
Maintenance and repair costs for owned and leased flight equipment are charged to operating expense as incurred, except costs incurred for maintenance and repair under flight hour maintenance contract agreements, which are accrued based on contractual terms when an obligation exists.
(k) Selling Expenses
Selling expenses include commissions, credit card fees, computerized reservations systems fees and advertising. Advertising expenses are expensed as incurred. Advertising expense was $86 million, $166 million and $153 million for the years ended December 31, 2014, 2013 and 2012, respectively.
(l) Share-based Compensation
American accounts for its share-based compensation expense based on the fair value of the stock award at the time of grant, which is recognized ratably over the vesting period of the stock award. The fair value of stock options and stock appreciation rights is estimated using a Black-Scholes option pricing model. The fair value of restricted stock units is based on the market price of the underlying shares of common stock on the date of grant. See Note 15 for further discussion of share-based compensation.
(m) Deferred Gains and Credits, Net
Included within deferred gains and credits, net are amounts deferred and amortized into future periods associated with deferred gains on the sale leaseback of aircraft and certain vendor incentives.
(n) Foreign Currency Gains and Losses
Foreign currency gains and losses are recorded as part of other nonoperating expense, net in American’s consolidated statements of operations. Foreign currency losses for 2014, 2013, and 2012 were $92 million, $55 million and $41 million, respectively.
(o) Regional Expenses
Expenses associated with American’s third-party regional carriers operating under the brand name American Eagle are classified as Regional expenses on the consolidated statements of operations. Regional expenses consist of the following (in millions):
		Year Ended December 31,
		2014			2013			2012
Aircraft fuel and related taxes		$	999		$	1,055		$	1,012

Total regional expenses		$	3,113		$	3,074		$	3,049
-1	For the year ended December 31, 2014, the component of capacity purchase expenses related to aircraft deemed to be leased was approximately $133 million.
(p) Recent Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09 completes the joint effort by the FASB and International Accounting Standards Board (IASB) to improve financial reporting by creating common revenue recognition guidance for U.S. GAAP and International Financial Reporting Standards (IFRS). ASU 2014-09 applies to all companies that enter into contracts with customers to transfer goods or services. ASU 2014-09 is effective for public entities for interim and annual reporting periods beginning after December 15, 2016. Early application is not permitted and entities have the choice to apply ASU 2014-09 either retrospectively to each reporting period presented or by recognizing the cumulative effect of applying ASU 2014-09 at the date of initial application and not adjusting comparative information. American is currently evaluating the requirements of ASU 2014-09 and has not yet determined its impact on American’s consolidated financial statements.

In addition, the Company recorded a net charge of $81 million for bankruptcy related items principally consisting of fair value adjustments for bankruptcy settlement obligations, $164 million in other special charges, including an $81 million charge to revise prior estimates of certain aircraft residual values, and other spare parts asset impairments, as well as $54 million in charges primarily relating to the buyout of certain aircraft leases. These charges were offset in part by a $309 million gain on the sale of Slots at DCA.
	The 2013 mainline operating special items, net included $443 million of primarily Merger related expenses due to the alignment of labor union contracts, professional fees, severance, share-based compensation and fees for US Airways to exit the Star Alliance and its codeshare agreement with United Airlines. In addition, the Company recorded a $107 million charge related to American’s pilot long-term disability obligation, a $43 million charge for workers’ compensation claims and a $33 million aircraft impairment charge. These charges were offset in part by a $67 million gain on the sale of Slots at LaGuardia Airport.
	The 2012 mainline operating special items, net consisted of $386 million of severance and related charges and write-off of leasehold improvements on aircraft and airport facilities that were rejected in connection with the Chapter 11 Cases.
	See Note 4 for more information on the Merger Agreement.
	The following additional amounts are also included in the consolidated statements of operations as follows (in millions):

	-2	The 2014 nonoperating special items totaled a net charge of $132 million, which principally included a $43 million charge for Venezuelan foreign currency losses, $56 million of early debt extinguishment costs related to the prepayment of 7.50% senior secured notes and other indebtedness and $33 million of non-cash interest accretion on bankruptcy settlement obligations. See Note 12 for further discussion on Venezuela cash and short-term investments.
	The 2013 nonoperating special items, net consisted of interest charges of $138 million to recognize post-petition interest expense on unsecured obligations pursuant to the Plan and penalty interest related to 10.5% secured notes and 7.50% senior secured notes, a $54 million charge related to the premium on tender for existing enhanced equipment trust certificates financings and the write-off of debt issuance costs, and $19 million in charges related to the repayment of existing EETC financings.
	The 2012 nonoperating special items, net consisted of a $280 million benefit resulting from a settlement of a commercial dispute.
	-3	In 2013 and 2012, the Company recognized reorganization expenses as a result of the filing of voluntary petitions for relief under Chapter 11. These amounts consisted primarily of estimated allowed claim amounts and professional fees.
	-4	In 2014, income tax special items, net were $346 million. During 2014, the Company sold its portfolio of fuel hedging contracts that were scheduled to settle on or after June 30, 2014. In connection with this sale, the Company recorded a special non-cash tax provision of $330 million in the second quarter of 2014 that reversed the non-cash tax provision which was recorded in other comprehensive income (OCI), a subset of stockholders’ equity, principally in 2009. This provision represents the tax effect associated with gains recorded in OCI principally in 2009 due to a net increase in the fair value of the Company’s fuel hedging contracts. In accordance with GAAP, the Company retained the $330 million tax provision in OCI until the last contract was settled or terminated. In addition, the 2014 period included a special $16 million non-cash deferred income tax provision related to certain indefinite-lived intangible assets.
	In 2013 and 2012, income tax special items, net included, respectively, a $538 million and a $569 million non-cash income tax benefit from continuing operations. The Company is required to consider all items (including items recorded in other comprehensive income) in determining the amount of tax benefit that results from a loss from continuing operations and that should be allocated to continuing operations. As a result, the Company recorded a tax benefit on the loss from continuing operations for the year, which was exactly offset by income tax expense on other comprehensive income. However, while the income tax benefit from continuing operations is reported on the income statement, the income tax expense on other comprehensive income is recorded directly to accumulated other comprehensive income (loss), which is a component of stockholders’ equity. Because the income tax expense on other comprehensive income is equal to the income tax benefit from continuing operations, the Company’s year-end net deferred tax position is not impacted by this tax allocation. The 2013 tax benefit was offset in part by a $214 million tax charge attributable to additional valuation allowance required to reduce deferred tax assets to the amount the Company believes is more likely than not to be realized.

In connection with this sale, American recorded a special non-cash tax provision of $328 million in the second quarter of 2014 that reversed the non-cash tax provision which was recorded in other comprehensive income (OCI), a subset of stockholder’s equity, principally in 2009. This provision represents the tax effect associated with gains recorded in OCI principally in 2009 due to a net increase in the fair value of American’s fuel hedging contracts. In accordance with GAAP, American retained the $328 million tax provision in OCI until the last contract was settled or terminated. In addition, the 2014 period included a special $14 million non-cash deferred income tax provision related to certain indefinite-lived intangible assets.
	In 2013 and 2012, income tax special items, net included, respectively, a $538 million and a $569 million non-cash income tax benefit from continuing operations. American is required to consider all items (including items recorded in other comprehensive income) in determining the amount of tax benefit that results from a loss from continuing operations and that should be allocated to continuing operations. As a result, American recorded a tax benefit on the loss from continuing operations for the year, which was exactly offset by income tax expense on other comprehensive income. However, while the income tax benefit from continuing operations is reported on the income statement, the income tax expense on other comprehensive income is recorded directly to accumulated other comprehensive income (loss), which is a component of stockholder’s equity. Because the income tax expense on other comprehensive income is equal to the income tax benefit from continuing operations, American’s year-end net deferred tax position is not impacted by this tax allocation. The 2013 tax benefit was offset in part by a $214 million tax charge attributable to additional valuation allowance required to reduce deferred tax assets to the amount American believes is more likely than not to be realized.

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	7.  Earnings (Loss) Per Share
	Pursuant to the Plan and the Merger Agreement, holders of AMR common stock formerly traded under the symbol “AAMRQ” received shares of AAG Common Stock principally over the 120-day distribution period following the Effective Date. In accordance with GAAP, the 2013 and 2012 weighted average shares and earnings (loss) per share calculations have been adjusted to retrospectively reflect these distributions which were each made at the rate of approximately 0.7441 shares of AAG Common Stock per share of AMR common stock. Former holders of AMR common stock as of the Effective Date may in the future receive additional distributions of AAG Common Stock dependent upon the ultimate distribution of shares of AAG Common Stock to holders of disputed claims. Thus, the shares and related earnings per share calculations prior to the Effective Date may change in the future to reflect additional retrospective adjustments for future AAG Common Stock distributions to former holders of AMR common stock.
	As of December 31, 2014, all shares pursuant to the Plan have been issued and are outstanding for purposes of the Company’s basic and diluted earnings per share calculation in connection with the conversion of AAG Series A Preferred Stock and satisfaction of other bankruptcy settlement obligations related to allowed unsecured claims, including disputed claims, labor-related deemed claims and former holders of AMR common stock.
	The following table sets forth the computation of basic and diluted earnings (loss) per share (in millions, except share and per share amounts in thousands):
			Year Ended December 31,

	(a)	In March 2014, the Company notified the holders of US Airways Group’s 7.25% convertible senior notes that it had elected to settle all future conversions solely in cash instead of shares of AAG Common Stock in accordance with the related indenture. Thus, the diluted shares include the weighted average impact of the 7.25% convertible senior notes only for the period from January 1, 2014 to March 12, 2014. In addition, under GAAP, the Company must adjust the numerator for purposes of calculating diluted earnings per share by the change in fair value of the conversion feature from March 12, 2014 to May 15, 2014, which increased GAAP net income for purposes of computing diluted earnings per share by $3 million for the year ended December 31, 2014.

Share Repurchase Program and Dividends	8.  Share Repurchase Program and Dividends
	On July 23, 2014, as part of a capital deployment program, the Company’s Board of Directors authorized a $1.0 billion share repurchase program to be completed no later than December 31, 2015. During the year ended December 31, 2014, the Company completed this $1.0 billion share repurchase program by repurchasing 23.4 million shares of AAG Common Stock for $1.0 billion at a weighted average cost per share of $42.72. On January 27, 2015, the Company announced that its Board of Directors had authorized a new $2.0 billion share repurchase program to be completed by the end of 2016. Shares repurchased under the program may be made through a variety of methods, which may include open market purchases, privately negotiated transactions, block trades or accelerated share repurchase transactions. Any such repurchases will be made from time to time subject to market and economic conditions, applicable legal requirements and other relevant factors. The program does not obligate the Company to repurchase any specific number of shares and may be suspended at any time at its discretion.
	Also on July 23, 2014, as part of the Company’s capital deployment program, the Company’s Board of Directors declared a $0.10 per share cash dividend for shareholders of record as of August 4, 2014, and payable on August 18, 2014.
	On October 22, 2014, the Company’s Board of Directors declared a $0.10 per share dividend for stockholders of record on November 3, 2014, and payable on November 17, 2014.
	The total cash payment for dividends during the year ended December 31, 2014 was $144 million. Any future dividends that may be declared and paid from time to time under the Company’s capital deployment program will be subject to market and economic conditions, applicable legal requirements and other relevant factors. The Company’s capital deployment program does not obligate the Company to continue a dividend for any fixed period, and payment of dividends may be suspended at any time at management’s discretion.

	(a) 2013 Credit Facilities
	On June 27, 2013, American and AAG entered into a Credit and Guaranty Agreement (as amended, the 2013 Credit Agreement) with certain lenders. The 2013 Credit Agreement provides for a term loan facility (the 2013 Term Loan Facility) that is scheduled to mature on June 27, 2019, unless otherwise extended by the applicable parties. As of December 31, 2014, $1.9 billion was outstanding under the 2013 Term Loan Facility.
	The 2013 Credit Agreement originally provided for a $1.0 billion revolving credit facility (the 2013 Revolving Facility and, together with the 2013 Term Loan Facility, the 2013 Credit Facilities) scheduled to mature on June 27, 2018, unless otherwise extended by the applicable parties. The 2013 Term Loan Facility is repayable in quarterly installments in an amount equal to 0.25% of the original principal amount thereof with any unpaid balance due on the maturity date of the 2013 Term Loan Facility. The 2013 Revolving Facility provided that American may from time to time borrow, repay and reborrow loans thereunder and have letters of credit issued thereunder in an aggregate amount outstanding at any time of up to $1.0 billion. On October 10, 2014, American and AAG amended the 2013 Credit Agreement to extend the maturity date of the 2013 Revolving Facility to October 10, 2019 and increased the commitments thereunder to an aggregate amount of $1.4 billion while reducing the letter of credit commitments thereunder to $300 million. As of December 31, 2014, there were no borrowings or letters of credit outstanding under the 2013 Revolving Facility.
	The 2013 Credit Facilities bear interest at an index rate plus an applicable index margin or, at American’s option, LIBOR (subject to a floor of 0.75%, with respect to the 2013 Term Loan Facility) plus an applicable LIBOR margin. The applicable LIBOR margin is 3.00% for borrowings under both the 2013 Term Loan Facility and the 2013 Revolving Facility.
	Upon consummation of the Merger, US Airways Group and US Airways joined the 2013 Credit Facilities as guarantors. Following the joinder, certain minimum dollar-thresholds under the negative and financial covenants in the 2013 Credit Facilities were automatically increased.
	Subject to certain limitations and exceptions, the 2013 Credit Facilities are secured by certain collateral, including certain route authorities and certain take-off and landing rights and gate leaseholds at certain airports. American is required to maintain a certain minimum ratio of appraised value of the collateral to the outstanding loans under the 2013 Credit Facilities as more fully described below in “Collateral Related Covenants.”
	The 2013 Credit Facilities contain events of default customary for similar financings, including cross default to other material indebtedness. Upon the occurrence of an event of default, the outstanding obligations under the 2013 Credit Facilities may be accelerated and become due and payable immediately. In addition, if a “change of control” (as defined in the 2013 Credit Agreement) occurs, American will (absent an amendment or waiver) be required to repay at par the loans outstanding under the 2013 Credit Facilities and terminate the 2013 Revolving Facility. The 2013 Credit Facilities also include covenants that, among other things, require AAG to maintain a minimum aggregate liquidity (as defined in the 2013 Credit Facilities) of not less than $2.0 billion, and limit the ability of AAG and its restricted subsidiaries to pay dividends and make certain other payments, make certain investments, incur additional indebtedness, incur liens on the collateral, dispose of the collateral, enter into certain affiliate transactions and engage in certain business activities, in each case subject to certain exceptions.
	(b) 2014 Credit Facilities
	On October 10, 2014, American, AAG, US Airways Group and US Airways entered into a Credit and Guaranty Agreement (the 2014 Credit Agreement) with certain lenders. The 2014 Credit Agreement provides for a $750 million term loan facility (the 2014 Term Loan Facility) and a $400 million revolving credit facility (the 2014 Revolving Facility and, together with the 2014 Term Loan Facility, the 2014 Credit Facilities). As of December 31, 2014, $750 million was outstanding under the 2014 Term Loan Facility. The 2014 Revolving Facility provides that American may from time to time borrow, repay and reborrow loans thereunder. American may have letters of credit issued under the 2014 Revolving Facility in an aggregate amount outstanding at any time up to $300 million. As of December 31, 2014 there were no borrowings or letters of credit outstanding under the 2014 Revolving Facility.
	Subject to certain limitations and exceptions, the 2014 Credit Facilities are secured by certain collateral, including certain route authorities and certain take-off and landing rights and gate leaseholds at certain airports. The obligations of American under the 2014 Credit Facilities are guaranteed by AAG, US Airways Group and US Airways. American is required to maintain a certain minimum ratio of appraised value of the collateral to the outstanding loans under the 2014 Credit Facilities as more fully described below in “Collateral Related Covenants.”
	The 2014 Term Loan Facility and 2014 Revolving Facility mature on October 10, 2021 and October 10, 2019, respectively, unless otherwise extended by the applicable parties. The 2014 Term Loan Facility is repayable in annual installments in an amount equal to 1.00% of the original principal balance with any unpaid balance due on the maturity date of the 2014 Term Loan Facility. Voluntary prepayments may be made by American at any time, with a premium of 1.00% applicable to certain prepayments made prior to the date that is six months following October 10, 2014.
	The 2014 Credit Facilities bear interest at an index rate plus an applicable index margin or, at American’s option, LIBOR (subject to a floor of 0.75% in the case of the 2014 Term Loan Facility) plus an applicable LIBOR margin. The applicable LIBOR margins are 3.50% and 3.00% for borrowings under the 2014 Term Loan Facility and the 2014 Revolving Facility, respectively. If American has a corporate credit rating of Ba3 or higher from Moody’s and BB- or higher from S&P, the applicable LIBOR margin is 3.25% under the 2014 Term Loan Facility.
	The 2014 Credit Facilities contain events of default customary for similar financings, including cross default to other material indebtedness. Upon the occurrence of an event of default, the outstanding obligations under the 2014 Credit Facilities may be accelerated and become due and payable immediately. In addition, if a “change of control” (as defined in the 2014 Credit Agreement) occurs with respect to AAG, American will (absent an amendment or waiver) be required to repay at par the loans outstanding under the 2014 Credit Facilities and terminate the 2014 Revolving Facility. The 2014 Credit Facilities also include covenants that, among other things, require AAG to maintain a minimum aggregate liquidity (as defined in the 2014 Credit Facilities) of not less than $2.0 billion, and limit the ability of AAG and its restricted subsidiaries to pay dividends and make certain other payments, make certain investments, incur liens on the collateral, dispose of the collateral, enter into certain affiliate transactions and engage in certain business activities, in each case subject to certain exceptions.
	(c) 2013 Citicorp Credit Facility
	US Airways Group and certain other subsidiaries of US Airways Group are guarantors of the 2013 Citicorp Credit Facility agreement dated as of May 23, 2013. In connection with the closing of the Merger, AAG and American entered into a joinder to the 2013 Citicorp Credit Facility loan agreement pursuant to which AAG and American became guarantors under such agreement.
	The 2013 Citicorp Credit Facility consists of tranche B-1 term loans (Tranche B-1) and tranche B-2 term loans (Tranche B-2). As of December 31, 2014, $990 million was outstanding under Tranche B-1 and $594 million was outstanding under Tranche B-2. Voluntary prepayments may be made at any time, with a premium of 1.00% applicable to certain prepayments made prior to the date that is six months following January 16, 2014.
	As of December 31, 2014, the 2013 Citicorp Credit Facility bears interest at an index rate plus an applicable index margin or, at US Airways’ option, LIBOR (subject to a floor of 0.75%) plus an applicable LIBOR margin. The applicable LIBOR margin is 2.75% for Tranche B-1 and 2.25% for Tranche B-2.
	Tranche B-1 and Tranche B-2 mature on May 23, 2019 and November 23, 2016, respectively (unless otherwise extended by the applicable parties), and each is repayable in annual installments to be paid on each anniversary of the closing date in an amount equal to 1.00% of the initial aggregate principal amount of the loans with any unpaid balance due on the maturity date of the respective tranche.
	Subject to certain limitations and exceptions, the obligations of US Airways under the 2013 Citicorp Credit Facility are secured by liens on certain take-off and landing rights at certain airports and certain other assets of US Airways. US Airways is required to maintain a certain minimum ratio of appraised value of the collateral to the outstanding loans under the 2013 Citicorp Credit Facility agreement as more fully described below in “Collateral Related Covenants”.
	The 2013 Citicorp Credit Facility agreement contains events of default customary for similar financings, including a cross default provision to certain other material indebtedness of US Airways and certain of its affiliates. Upon the occurrence of an event of default, the outstanding obligations under the 2013 Citicorp Credit Facility may be accelerated and become due and payable immediately. In addition, if a “change of control” (as defined in the 2013 Citicorp Credit Facility agreement) occurs, US Airways will (absent an amendment or waiver) be required to repay the outstanding loans in full together with accrued interest thereon to the date of such prepayment. The 2013 Citicorp Credit Facility agreement includes affirmative, negative and financial covenants that, among other things, (a) require AAG and its restricted subsidiaries to maintain unrestricted liquidity of not less than $2.0 billion, with not less than $750 million held in accounts subject to control agreements, and (b) restrict the ability of US Airways Group, its subsidiaries party to the 2013 Citicorp Credit Facility, AAG and American to make certain investments, pay dividends and make certain other payments, make certain acquisitions, incur liens on the collateral, dispose of collateral, enter into certain affiliate transactions, enter into certain hedging transactions, and engage in certain business activities, in each case subject to certain exceptions.
	(d) Aircraft Enhanced Equipment Trust Certificates (EETCs)
	2014-1 EETCs
	In September 2014, American created two pass-through trusts which issued approximately $957 million aggregate face amount of Series 2014-1 Class A and Class B EETCs in connection with the financing of 17 aircraft recently delivered to, and owned by, American (the 2014 EETC Aircraft).
	As of December 31, 2014, the full $957 million of the escrowed proceeds from the 2014-1 EETCs have been used to purchase equipment notes issued by American in two series: Series A equipment notes in the amount of $742 million bearing interest at 3.70% per annum and Series B equipment notes in the amount of $215 million bearing interest at 4.375% per annum. Interest and principal payments on the equipment notes are scheduled to be made in April and October of each year, beginning in April 2015. The final payments on the Series A and Series B equipment notes will be due in October 2026 and October 2022, respectively. The equipment notes are secured by liens on the 2014 EETC Aircraft.
	2013-1 EETCs
	During 2014, US Airways issued $559 million of equipment notes in two series under its 2013-1 EETCs completed in April 2013: Series A equipment notes in the amount of $423 million bearing interest at 3.95% per annum and Series B equipment notes in the amount of $136 million bearing interest at 5.375% per annum. As of December 31, 2014, the full $820 million of the escrowed proceeds from US Airways’ 2013-1 EETCs have been used to purchase Series A and Series B equipment notes issued by US Airways. The equipment notes are secured by liens on aircraft.
	(e) Other Aircraft Financing Transactions
	In May 2014, the Company prepaid $113 million principal amount of outstanding debt secured by certain aircraft.
	During 2014, American entered into loan agreements to borrow $286 million in connection with financing certain aircraft deliveries. The notes mature in 2026 and bear interest at a rate of LIBOR plus an applicable margin.
	During 2014, American financed 20 Boeing 737-800 aircraft under sale-leaseback arrangements and recorded proceeds from the sale of $811 million. Of the 20 Boeing 737-800 aircraft, 19 aircraft were accounted for as a capital lease and $747 million was reflected as debt on the consolidated balance sheet, included within other secured obligations in the table above. Gains associated with these sale-leaseback transactions are amortized over the respective remaining lease terms and are included in the consolidated balance sheet as deferred gains.
(f) Obligations Associated with Special Facility Revenue Bonds
In 2014, the Company prepaid $314 million of obligations, of which $135 million was a reduction of debt on the Company’s balance sheet, associated with special facility revenue bonds issued by municipalities to build or improve certain airport and maintenance facilities. The remaining portion of these obligations was accounted for as an operating lease.
In addition, in August 2014, American elected to exercise its option to reset the interest rate on approximately $220 million aggregate principal amount of special facility revenue bonds reflected as debt on its balance sheet, related to the Los Angeles International Airport, resulting in the repurchase of these bonds by American in September 2014. American has the option to remarket these bonds in the future. In connection with the repurchase of these bonds, American paid $2 million in cash premiums and recorded a $5 million non-cash write off of unamortized debt discount and issuance costs.
In December 2014, American purchased approximately $112 million aggregate principal amount of special facility revenue bonds related to the Tulsa International Airport, when such bonds were mandatorily tendered to American. Of this amount, $11 million was a reduction of debt on American’s balance sheet. American has the option to remarket these bonds in the future.
(g) Senior Secured Notes
In March 2014, American prepaid $100 million of its 7.50% senior secured notes at a redemption price of 103% of their principal amount plus accrued and unpaid interest. In July 2014, American prepaid the remaining outstanding principal balance of $900 million at a redemption price of 103.75% of outstanding principal amount plus accrued and unpaid interest. In connection with the prepayment of the outstanding 7.50% senior secured notes, American paid $37 million of cash premiums and recorded a $5 million non-cash write off of unamortized deferred issuance costs during the year ended December 31, 2014.
(h) AAdvantage Loan
In 2009, American entered into an arrangement under which Citibank loaned American $1.0 billion that could be repaid either in AAdvantage miles under American’s AAdvantage program or in cash (the AAdvantage Loan). Approximately $890 million of the AAdvantage Loan proceeds was accounted for as a loan from Citibank with the remaining $110 million recorded as deferred revenue in other liabilities and deferred credits.
To effect the AAdvantage Loan, American and Citibank entered into an Amended and Restated AAdvantage Participation Agreement (as so amended and restated, the Amended Participation Agreement). Under the Amended Participation Agreement, American agreed that it would apply in equal monthly installments over a five year period beginning on January 1, 2012, a credit for miles awarded to Citibank cardholders’ AAdvantage accounts.
American had the right to repay in cash, without premium or penalty, any or all of the amounts owed to Citibank under the AAdvantage Loan. Effective January 2, 2015, American exercised its loan repayment right with respect to the full value of the outstanding balance to Citibank for $400 million. In connection with the repayment, in the first quarter of 2015, American will recognize an early debt extinguishment gain of approximately $17 million. The entire outstanding balance of the obligation is reflected in current maturities of long-term debt on the accompanying consolidated balance sheet as of December 31, 2014.
(i) 5.50% Senior Notes
In September 2014, the Company issued $750 million aggregate principal amount of 5.50% senior notes due 2019 (the 5.50% senior notes). These notes bear interest at a rate of 5.50% per annum, which is payable semi-annually in arrears on each April 1 and October 1, beginning April 1, 2015. The 5.50% senior notes mature on October 1, 2019 and are fully and unconditionally guaranteed by American, US Airways Group and US Airways. The 5.50% senior notes are senior unsecured obligations of the Company. The indenture for the 5.50% senior notes contains covenants and events of default generally customary for similar financings. In addition, if the Company experiences specific kinds of changes of control, the Company must offer to repurchase the 5.50% senior notes at a price of 101% of the principal amount plus accrued and unpaid interest, if any, to the repurchase date. Upon the occurrence of certain events of default, the 5.50% senior notes may be accelerated and become due and payable.
(j) 6.125% Senior Notes
In May 2013, US Airways Group issued its 6.125% Senior Notes due 2018 (the 6.125% senior notes). The 6.125% senior notes bear interest at a rate of 6.125% per annum, which is payable semi-annually on each June 1 and December 1 and began December 1, 2013. The 6.125% senior notes mature on June 1, 2018 and are fully and unconditionally guaranteed by US Airways. In connection with the closing of the Merger, AAG and American provided a full and unconditional guarantee of the payment obligations of US Airways Group under the 6.125% senior notes. The 6.125% senior notes are general unsecured senior obligations of the Company.
(k) 7.25% Convertible Notes
In March 2014, the Company notified the holders of US Airways Group’s 7.25% convertible notes that it had elected to settle solely in cash instead of shares of AAG Common Stock all conversions during the period beginning on March 15, 2014 and ending on, and including, the second scheduled trading day immediately preceding the maturity date of May 15, 2014. In May 2014, the Company settled all outstanding 7.25% convertible notes in cash for approximately $175 million.

As of December 31, 2014, AAG had issued guarantees covering approximately $1.1 billion of American’s tax-exempt bond debt (and interest thereon) and $4.4 billion of American’s secured debt (and interest thereon).
In connection with the Merger and pursuant to the Plan on December 9, 2013, the Company and American entered into a joinder to the loan agreement and became co-obligors of US Airways Group’s $1.6 billion 2013 Citicorp Credit Facility and the Company and American entered into a second supplemental indenture that guarantees the payment obligations associated with the 6.125% senior notes. In March 2014, AAG, US Airways Group and US Airways entered into amended and restated guarantees of the payment obligations of US Airways under the equipment notes relating to each of its Series 2010-1, 2011-1, 2012-1, 2012-2 and 2013-1 Pass Through Certificates, the result of which was to add AAG as a guarantor of such equipment notes on a joint and several basis with US Airways Group. Refer to Note 21 for further information.
Collateral Related Covenants
Certain of the Company’s debt financing agreements contain loan to value ratio covenants and require it to periodically appraise the related collateral. Pursuant to such agreements, if the loan to value ratio exceeds a specified threshold, the Company is required, as applicable, to pledge additional qualifying collateral (which in some cases may include cash collateral), or pay down such financing, in whole or in part, as described below.
Specifically, the Company is required to meet certain collateral coverage tests on a periodic basis on three Credit Facilities, as described below:
		2014 Credit Facilities		2013 Credit Facilities	2013 Citicorp Credit Facility
Frequency of Appraisals of Appraised Collateral		Annual		Semi-Annual	Once per Fiscal Year (1)
LTV Requirement		1.6x Collateral valuation to amount of debt outstanding (62.5% LTV)		1.6x Collateral valuation to amount of debt outstanding (62.5% LTV)	1.5x Collateral valuation to amount of debt outstanding (66.7% LTV)
LTV as of Last Measurement Date		21.90%		33.70%	61.80%
Collateral		Generally, certain route authorities, take-off and landing slots, and rights to airport facilities used by American to operate certain services between the U.S. and London Heathrow, Tokyo Narita, and China		Generally, certain route authorities, take-off and landing slots, and rights to airport facilities used by American to operate all services between the U.S. and South America	Generally, certain Slots (e.g., DCA and LaGuardia), accounts receivable, certain engines, certain spare parts and ground service equipment, certain simulators, certain leasehold real estate assets and cash

	(a) 2013 Credit Facilities
	On June 27, 2013, American and AAG entered into a Credit and Guaranty Agreement (as amended, the 2013 Credit Agreement) with certain lenders. The 2013 Credit Agreement provides for a term loan facility (the 2013 Term Loan Facility) that is scheduled to mature on June 27, 2019, unless otherwise extended by the applicable parties. As of December 31, 2014, $1.9 billion was outstanding under the 2013 Term Loan Facility.
	The 2013 Credit Agreement originally provided for a $1.0 billion revolving credit facility (the 2013 Revolving Facility and, together with the 2013 Term Loan Facility, the 2013 Credit Facilities) scheduled to mature on June 27, 2018, unless otherwise extended by the applicable parties. The 2013 Term Loan Facility is repayable in quarterly installments in an amount equal to 0.25% of the original principal amount thereof with any unpaid balance due on the maturity date of the 2013 Term Loan Facility. The 2013 Revolving Facility provided that American may from time to time borrow, repay and reborrow loans thereunder and have letters of credit issued thereunder in an aggregate amount outstanding at any time of up to $1.0 billion. On October 10, 2014, American and AAG amended the 2013 Credit Agreement to extend the maturity date of the 2013 Revolving Facility to October 10, 2019 and increased the commitments thereunder to an aggregate amount of $1.4 billion while reducing the letter of credit commitments thereunder to $300 million. As of December 31, 2014, there were no borrowings or letters of credit outstanding under the 2013 Revolving Facility.
	The 2013 Credit Facilities bear interest at an index rate plus an applicable index margin or, at American’s option, LIBOR (subject to a floor of 0.75%, with respect to the 2013 Term Loan Facility) plus an applicable LIBOR margin. The applicable LIBOR margin is 3.00% for borrowings under both the 2013 Term Loan Facility and the 2013 Revolving Facility.
	Upon consummation of the Merger, US Airways Group and US Airways joined the 2013 Credit Facilities as guarantors. Following the joinder, certain minimum dollar-thresholds under the negative and financial covenants in the 2013 Credit Facilities were automatically increased.
	Subject to certain limitations and exceptions, the 2013 Credit Facilities are secured by certain collateral, including certain route authorities and certain take-off and landing rights and gate leaseholds at certain airports. American is required to maintain a certain minimum ratio of appraised value of the collateral to the outstanding loans under the 2013 Credit Facilities as more fully described below in “Collateral Related Covenants.”
	The 2013 Credit Facilities contain events of default customary for similar financings, including cross default to other material indebtedness. Upon the occurrence of an event of default, the outstanding obligations under the 2013 Credit Facilities may be accelerated and become due and payable immediately. In addition, if a “change of control” (as defined in the 2013 Credit Agreement) occurs, American will (absent an amendment or waiver) be required to repay at par the loans outstanding under the 2013 Credit Facilities and terminate the 2013 Revolving Facility. The 2013 Credit Facilities also include covenants that, among other things, require AAG to maintain a minimum aggregate liquidity (as defined in the 2013 Credit Facilities) of not less than $2.0 billion, and limit the ability of AAG and its restricted subsidiaries to pay dividends and make certain other payments, make certain investments, incur additional indebtedness, incur liens on the collateral, dispose of the collateral, enter into certain affiliate transactions and engage in certain business activities, in each case subject to certain exceptions.
	(b) 2014 Credit Facilities
	On October 10, 2014, American, AAG, US Airways Group and US Airways entered into a Credit and Guaranty Agreement (the 2014 Credit Agreement) with certain lenders. The 2014 Credit Agreement provides for a $750 million term loan facility (the 2014 Term Loan Facility) and a $400 million revolving credit facility (the 2014 Revolving Facility and, together with the 2014 Term Loan Facility, the 2014 Credit Facilities). As of December 31, 2014, $750 million was outstanding under the 2014 Term Loan Facility. The 2014 Revolving Facility provides that American may from time to time borrow, repay and reborrow loans thereunder. American may have letters of credit issued under the 2014 Revolving Facility in an aggregate amount outstanding at any time up to $300 million. As of December 31, 2014 there were no borrowings or letters of credit outstanding under the 2014 Revolving Facility.
	Subject to certain limitations and exceptions, the 2014 Credit Facilities are secured by certain collateral, including certain route authorities and certain take-off and landing rights and gate leaseholds at certain airports. The obligations of American under the 2014 Credit Facilities are guaranteed by AAG, US Airways Group and US Airways. American is required to maintain a certain minimum ratio of appraised value of the collateral to the outstanding loans under the 2014 Credit Facilities as more fully described below in “Collateral Related Covenants.”
	The 2014 Term Loan Facility and 2014 Revolving Facility mature on October 10, 2021 and October 10, 2019, respectively, unless otherwise extended by the applicable parties. The 2014 Term Loan Facility is repayable in annual installments in an amount equal to 1.00% of the original principal balance with any unpaid balance due on the maturity date of the 2014 Term Loan Facility. Voluntary prepayments may be made by American at any time, with a premium of 1.00% applicable to certain prepayments made prior to the date that is six months following October 10, 2014.
	The 2014 Credit Facilities bear interest at an index rate plus an applicable index margin or, at American’s option, LIBOR (subject to a floor of 0.75% in the case of the 2014 Term Loan Facility) plus an applicable LIBOR margin. The applicable LIBOR margins are 3.50% and 3.00% for borrowings under the 2014 Term Loan Facility and the 2014 Revolving Facility, respectively. If American has a corporate credit rating of Ba3 or higher from Moody’s and BB- or higher from S&P, the applicable LIBOR margin is 3.25% under the 2014 Term Loan Facility.
	The 2014 Credit Facilities contain events of default customary for similar financings, including cross default to other material indebtedness. Upon the occurrence of an event of default, the outstanding obligations under the 2014 Credit Facilities may be accelerated and become due and payable immediately. In addition, if a “change of control” (as defined in the 2014 Credit Agreement) occurs with respect to AAG, American will (absent an amendment or waiver) be required to repay at par the loans outstanding under the 2014 Credit Facilities and terminate the 2014 Revolving Facility. The 2014 Credit Facilities also include covenants that, among other things, require AAG to maintain a minimum aggregate liquidity (as defined in the 2014 Credit Facilities) of not less than $2.0 billion, and limit the ability of AAG and its restricted subsidiaries to pay dividends and make certain other payments, make certain investments, incur liens on the collateral, dispose of the collateral, enter into certain affiliate transactions and engage in certain business activities, in each case subject to certain exceptions.
	(c) Aircraft Enhanced Equipment Trust Certificates (EETCs)
	2014-1 EETCs
	In September 2014, American created two pass-through trusts which issued approximately $957 million aggregate face amount of Series 2014-1 Class A and Class B EETCs in connection with the financing of 17 aircraft recently delivered to, and owned by, American (the 2014 EETC Aircraft).
	As of December 31, 2014, the full $957 million of the escrowed proceeds from the 2014-1 EETCs have been used to purchase equipment notes issued by American in two series: Series A equipment notes in the amount of $742 million bearing interest at 3.70% per annum and Series B equipment notes in the amount of $215 million bearing interest at 4.375% per annum. Interest and principal payments on the equipment notes are scheduled to be made in April and October of each year, beginning in April 2015. The final payments on the Series A and Series B equipment notes will be due in October 2026 and October 2022, respectively. The equipment notes are secured by liens on the 2014 EETC Aircraft.
	(d) Other Aircraft Financing Transactions
	In May 2014, American prepaid $61 million principal amount of outstanding debt secured by certain aircraft.
	During 2014, American entered into loan agreements to borrow $286 million in connection with financing certain aircraft deliveries. The notes mature in 2026 and bear interest at a rate of LIBOR plus an applicable margin.
	During 2014, American financed 20 Boeing 737-800 aircraft under sale-leaseback arrangements and recorded proceeds from the sale of $811 million. Of the 20 Boeing 737-800 aircraft, 19 aircraft were accounted for as a capital lease and $747 million was reflected as debt on the consolidated balance sheet, included within other secured obligations in the table above. Gains associated with these sale-leaseback transactions are amortized over the respective remaining lease terms and are included in the consolidated balance sheet as deferred gains.
	(e) Obligations Associated with Special Facility Revenue Bonds
	In 2014, American prepaid $98 million of obligations, of which $62 million was a reduction of debt on its balance sheet, associated with special facility revenue bonds issued by municipalities to build or improve certain airport and maintenance facilities. The remaining portion of these obligations was accounted for as an operating lease.
	In addition, in August 2014, American elected to exercise its option to reset the interest rate on approximately $220 million aggregate principal amount of special facility revenue bonds reflected as debt on its balance sheet, related to the Los Angeles International Airport, resulting in the repurchase of these bonds by American in September 2014. American has the option to remarket these bonds in the future. In connection with the repurchase of these bonds, American paid $2 million in cash premiums and recorded a $5 million non-cash write off of unamortized debt discount and issuance costs.
	In December 2014, American purchased approximately $112 million aggregate principal amount of special facility revenue bonds related to the Tulsa International Airport, when such bonds were mandatorily tendered to American. Of this amount, $11 million was a reduction of debt on American’s balance sheet. American has the option to remarket these bonds in the future.
	(f) Senior Secured Notes
	In March 2014, American prepaid $100 million of its 7.50% senior secured notes at a redemption price of 103% of their principal amount plus accrued and unpaid interest. In July 2014, American prepaid the remaining outstanding principal balance of $900 million at a redemption price of 103.75% of outstanding principal amount plus accrued and unpaid interest. In connection with the prepayment of the outstanding 7.50% senior secured notes, American paid $37 million of cash premiums and recorded a $5 million non-cash write off of unamortized deferred issuance costs during the year ended December 31, 2014.
	(g) AAdvantage Loan
	In 2009, American entered into an arrangement under which Citibank loaned American $1.0 billion that could be repaid either in AAdvantage miles under American’s AAdvantage program or in cash (the AAdvantage Loan). Approximately $890 million of the AAdvantage Loan proceeds was accounted for as a loan from Citibank with the remaining $110 million recorded as deferred revenue in other liabilities and deferred credits.
	To effect the AAdvantage Loan, American and Citibank entered into an Amended and Restated AAdvantage Participation Agreement (as so amended and restated, the Amended Participation Agreement). Under the Amended Participation Agreement, American agreed that it would apply in equal monthly installments over a five year period beginning on January 1, 2012, a credit for miles awarded to Citibank cardholders’ AAdvantage accounts.
	American had the right to repay in cash, without premium or penalty, any or all of the amounts owed to Citibank under the AAdvantage Loan. Effective January 2, 2015, American exercised its loan repayment right with respect to the full value of the outstanding balance to Citibank for $400 million. In connection with the repayment, in the first quarter of 2015, American will recognize an early debt extinguishment gain of approximately $17 million. The entire outstanding balance of the obligation is reflected in current maturities of long-term debt on the accompanying consolidated balance sheet as of December 31, 2014.
	Collateral Related Covenants
	Certain of American’s debt financing agreements contain loan to value ratio covenants and require American to periodically appraise the related collateral. Pursuant to such agreements, if the loan to value ratio exceeds a specified threshold, American is required, as applicable, to pledge additional qualifying collateral (which in some cases may include cash collateral), or pay down such financing, in whole or in part, as described below.
	Specifically, American is required to meet certain collateral coverage tests on a periodic basis on two Credit Facilities, as described below:

	As a result of the Merger, US Airways Group and its subsidiaries are included in the AAG consolidated federal and state income tax returns for the period ended December 31, 2014.
	For the year ended December 31, 2014, the Company recorded a $330 million tax provision. This provision included $346 million of special tax charges. During 2014, the Company sold its portfolio of fuel hedging contracts that were scheduled to settle on or after June 30, 2014. In connection with this sale, the Company recorded a special non-cash tax provision of $330 million in the second quarter of 2014 that reversed the non-cash tax provision which was recorded in other comprehensive income (OCI), a subset of stockholders’ equity, principally in 2009. This provision represents the tax effect associated with gains recorded in OCI principally in 2009 due to a net increase in the fair value of our fuel hedging contracts. In accordance with GAAP, the Company retained the $330 million tax provision in OCI until the last contract was settled or terminated. The Company also recorded a special $16 million non-cash deferred income tax provision related to certain indefinite-lived intangible assets. In addition, the Company recorded $8 million of tax expense principally related to certain states and countries where NOL Carryforwards were limited or unavailable to be used. These charges were offset in part by a $24 million federal income tax benefit resulting from the Company’s elections under applicable sections of the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 and the Housing and Economic Recovery Act of 2008 (as extended by the Tax Increase Prevention Act of 2014), allowing corporations to accelerate utilization of certain research and AMT credit carryforwards in lieu of applicable bonus depreciation on certain qualifying capital investments.
	For the year ended December 31, 2013, the Company recorded a $346 million tax benefit. This benefit included a $538 million special non-cash income tax benefit from continuing operations. The Company is required to consider all items (including items recorded in OCI) in determining the amount of tax benefit that results from a loss from continuing operations and that should be allocated to continuing operations. As a result, the Company recorded a tax benefit on the loss from continuing operations for the year, which was exactly offset by income tax expense on OCI. However, while the income tax benefit from continuing operations is reported on the income statement, the income tax expense on other comprehensive income is recorded directly to accumulated other comprehensive income (loss), which is a component of stockholders’ equity. Because the income tax expense on other comprehensive income is equal to the income tax benefit from continuing operations, the Company’s year-end net deferred tax position is not impacted by this tax allocation. The 2013 tax benefit was offset in part by a $214 million tax charge attributable to additional valuation allowance required to reduce deferred tax assets to the amount the Company believes is more likely than not to be realized. In addition, the Company recorded a $22 million federal income tax benefit under the Housing and Economic Recovery Act of 2008 as described above.
	For the year ended December 31, 2012, the Company recorded a net income tax benefit of $569 million, which represents the non-cash income tax benefit resulting from gains recorded in OCI as discussed above.
	The Company provides a valuation allowance for deferred tax assets when it is more likely than not that some portion, or all of its deferred tax assets, will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income (primarily reversals of deferred tax liabilities) during the periods in which those temporary differences will become deductible. In making this determination, the Company considers all available positive and negative evidence and makes certain assumptions. The Company considers many factors in evaluating the realizability of its deferred tax assets including risks associated with merger integration as well as other factors, which continue to be affected by conditions beyond the Company’s control, such as the condition of the economy, the level and volatility of fuel prices and travel demand. The Company has concluded as of December 31, 2014 that the valuation allowance was still needed on its deferred tax asset based on the weight of the factors described above.
	A portion of the change in the valuation allowance reflects the income tax benefit of approximately $24 million and $22 million, respectively, recorded in 2014 and 2013 resulting from the Company’s elections under applicable sections of the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 and the Housing and Economic Recovery Act of 2008 (as extended by the Tax Increase Prevention Act of 2014 and the American Taxpayer Relief Act of 2012), allowing corporations to accelerate utilization of certain research and alternative minimum tax (AMT) credit carryforwards in lieu of applicable bonus depreciation on certain qualifying capital investments.
	In addition to the changes in the valuation allowance from operations described in the table above, the valuation allowance was also impacted by the changes in the components of accumulated other comprehensive income (loss), described in Note 14 to AAG’s consolidated financial statements. The total decrease in the valuation allowance was $197 million in 2014 and the total increase in the valuation allowance was $602 million and $263 million in 2013 and 2012, respectively.

	At December 31, 2014, the Company had approximately $10.1 billion of gross NOL Carryforwards to reduce future federal taxable income, substantially all of which are expected to be available for use in 2015. The federal NOL Carryforwards will expire beginning in 2022 if unused. These NOL Carryforwards include an unrealized tax benefit of $867 million related to the implementation of share-based compensation accounting guidance that will be recorded in equity when realized. The Company also had approximately $4.6 billion of NOL Carryforwards to reduce future state taxable income at December 31, 2014, which will expire in years 2015 through 2034 if unused. The Company’s ability to deduct its NOL Carryforwards and to utilize certain other available tax attributes can be substantially constrained under the general annual limitation rules of Section 382 where an “ownership change” has occurred. The Company experienced an ownership change in connection with its emergence from the Chapter 11 Cases, and US Airways Group experienced an ownership change in connection with the Merger. As a result of the Merger, US Airways Group is now included in the AAG consolidated federal and state income tax return. The general limitation rules of Section 382 for a debtor in a bankruptcy case are liberalized where the ownership change occurs upon emergence from bankruptcy. The Company elected to be covered by certain special rules for federal income tax purposes that permit approximately $9.0 billion of its federal NOL Carryforwards to be utilized without regard to the Section 382 annual limitation rules. Substantially all of the Company’s remaining federal NOL Carryforwards (attributable to US Airways Group) are subject to limitation under Section 382; however, the Company’s ability to utilize such NOL Carryforwards is not anticipated to be effectively constrained as a result of such limitation. Similar limitations may apply for state income tax purposes. The Company’s ability to utilize any new NOL Carryforwards arising after the ownership changes is not affected by the annual limitation rules imposed by Section 382 unless another ownership change occurs. Under the Section 382 Limitation cumulative stock ownership changes among material shareholders exceeding 50% during a rolling 3-year period can potentially limit a company’s future use of net operating losses and tax credits. See Part I, Item 1A. Risk Factors – “Our ability to utilize our NOL Carryforwards may be limited” for additional unaudited discussion of this risk.
	At December 31, 2014, the Company had an AMT credit carryforward of approximately $341 million available for federal income tax purposes, which is available for an indefinite period. The Company’s net deferred tax assets, which include the NOL Carryforwards, are subject to a full valuation allowance. At December 31, 2014, the federal and state valuation allowances were $4.5 billion and $264 million, respectively. In accordance with GAAP, utilization of the NOL Carryforwards after December 9, 2013 will result in a corresponding decrease in the valuation allowance and offset our tax provision dollar for dollar.
	The Company files its tax returns as prescribed by the tax laws of the jurisdictions in which it operates. The Company’s 2004 through 2013 tax years are still subject to examination by the Internal Revenue Service.

	For the year ended December 31, 2014, American recorded a $319 million tax provision. This provision included $342 million of special tax charges. During 2014, American sold its portfolio of fuel hedging contracts that were scheduled to settle on or after June 30, 2014. In connection with this sale, American recorded a special non-cash tax provision of $328 million in the second quarter of 2014 that reversed the non-cash tax provision which was recorded in other comprehensive income (OCI), a subset of stockholders’ equity, principally in 2009. This provision represents the tax effect associated with gains recorded in OCI principally in 2009 due to a net increase in the fair value of our fuel hedging contracts. In accordance with GAAP, American retained the $328 million tax provision in OCI until the last contract was settled or terminated. American also recorded a special $14 million non-cash deferred income tax provision related to certain indefinite-lived intangible assets. In addition, American recorded $6 million of tax expense principally related to certain states and countries where NOL Carryforwards were limited or unavailable to be used. These charges were offset in part by a $29 million federal income tax benefit resulting from American’s elections under applicable sections of the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 and the Housing and Economic Recovery Act of 2008 (as extended by the Tax Increase Prevention Act of 2014), allowing corporations to accelerate utilization of certain research and AMT credit carryforwards in lieu of applicable bonus depreciation on certain qualifying capital investments.
	For the year ended December 31, 2013, American recorded a $354 million tax benefit. This benefit included a $538 million special non-cash income tax benefit from continuing operations. American is required to consider all items (including items recorded in OCI) in determining the amount of tax benefit that results from a loss from continuing operations and that should be allocated to continuing operations. As a result, American recorded a tax benefit on the loss from continuing operations for the year, which was exactly offset by income tax expense on OCI. However, while the income tax benefit from continuing operations is reported on the income statement, the income tax expense on other comprehensive income is recorded directly to accumulated other comprehensive income (loss), which is a component of stockholder’s equity. Because the income tax expense on other comprehensive income is equal to the income tax benefit from continuing operations, American’s year-end net deferred tax position is not impacted by this tax allocation. The 2013 tax benefit was offset in part by a $214 million tax charge attributable to additional valuation allowance required to reduce deferred tax assets to the amount American believes is more likely than not to be realized. In addition, American recorded a $30 million federal income tax benefit under the Housing and Economic Recovery Act of 2008 as described above.
	For the year ended December 31, 2012, American recorded a net income tax benefit of $569 million, which represents the non-cash income tax benefit resulting from gains recorded in OCI as discussed above.
	American provides a valuation allowance for deferred tax assets when it is more likely than not that some portion, or all of its deferred tax assets, will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income (primarily reversals of deferred tax liabilities) during the periods in which those temporary differences will become deductible. In making this determination, American considers all available positive and negative evidence and makes certain assumptions. American considers many factors in evaluating the realizability of its deferred tax assets including risks associated with merger integration as well as other factors, which continue to be affected by conditions beyond American’s control, such as the condition of the economy, the level and volatility of fuel prices and travel demand. American has concluded as of December 31, 2014 that the valuation allowance was still needed on its deferred tax asset based on the weight of the factors described above.
	A portion of the change in the valuation allowance reflects the income tax benefit of approximately $29 million and $30 million, respectively, recorded in 2014 and 2013 resulting from American’s elections under applicable sections of the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 and the Housing and Economic Recovery Act of 2008 (as extended by the Tax Increase Prevention Act of 2014 and the American Taxpayer Relief Act of 2012), allowing corporations to accelerate utilization of certain research and alternative minimum tax (AMT) credit carryforwards in lieu of applicable bonus depreciation on certain qualifying capital investments.
	In addition to the changes in the valuation allowance from operations described in the table above, the valuation allowance was also impacted by the changes in the components of accumulated other comprehensive income (loss), described in Note 11 to American’s consolidated financial statements. The total increase in the valuation allowance was $69 million, $155 million and $282 million in 2014, 2013 and 2012, respectively.

	At December 31, 2014, American had approximately $10.3 billion of gross NOL Carryforwards to reduce future federal taxable income, substantially all of which are expected to be available for use in 2015. American is a member of AAG’s consolidated federal and certain state income tax returns. The amount of federal and state NOL Carryforwards available in those returns is $10.1 billion and $4.6 billion, respectively, substantially all of which is expected to be available for use in 2015. The federal NOL Carryforwards will expire beginning in 2022 if unused. These NOL Carryforwards include an unrealized tax benefit of $712 million related to the implementation of share-based compensation accounting guidance that will be recorded in equity when realized. American also had approximately $3.9 billion of NOL Carryforwards to reduce future state taxable income at December 31, 2014, which will expire in years 2015 through 2034 if unused. American’s ability to deduct its NOL Carryforwards and to utilize certain other available tax attributes can be substantially constrained under the general annual limitation rules of Section 382 where an “ownership change” has occurred. American experienced an ownership change in connection with its emergence from the Chapter 11 Cases. The general limitation rules of Section 382 for a debtor in a bankruptcy case are liberalized where the ownership change occurs upon emergence from bankruptcy. American elected to be covered by certain special rules for federal income tax purposes that permit approximately $9.5 billion of its federal NOL Carryforwards to be utilized without regard to the Section 382 annual limitation rules. Similar limitations may apply for state income tax purposes. American’s ability to utilize any new NOL Carryforwards arising after the ownership change is not affected by the annual limitation rules imposed by Section 382 unless another ownership change occurs.
	At December 31, 2014, American had an AMT credit carryforward of approximately $435 million available for federal income tax purposes, which is available for an indefinite period. American’s net deferred tax assets, which include the NOL Carryforwards, are subject to a full valuation allowance. At December 31, 2014, the federal and state valuation allowances were $5.1 billion and $208 million, respectively. In accordance with GAAP, utilization of the NOL Carryforwards after December 9, 2013 will result in a corresponding decrease in the valuation allowance and offset American’s tax provision dollar for dollar.
	American files its tax returns as prescribed by the tax laws of the jurisdictions in which it operates. American’s 2004 through 2013 tax years are still subject to examination by the Internal Revenue Service. Various state and foreign jurisdiction tax years remain open to examination and American is under examination, in administrative appeals, or engaged in tax litigation in certain jurisdictions. American believes that the effect of additional assessments will be immaterial to its consolidated financial statements.
	American has an unrecognized tax benefit of approximately $5 million, which did not change during the twelve months ended December 31, 2014. Changes in the unrecognized tax benefit have no impact on the effective tax rate due to the existence of the valuation allowance. Accrued interest on tax positions is recorded as a component of interest expense but was not significant at December 31, 2014.

Risk Management and Financial Instruments	11.  Risk Management and Financial Instruments
	The Company’s economic prospects are heavily dependent upon two variables it cannot control: the health of the economy and the price of fuel.
	Due to the discretionary nature of business and leisure travel spending, airline industry revenues are heavily influenced by the condition of the U.S. economy and economies in other regions of the world. Unfavorable conditions in these broader economies have resulted, and may result in the future, in decreased passenger demand for air travel and changes in booking practices, both of which in turn have had, and may have in the future, a strong negative effect on the Company’s revenues. In addition, during challenging economic times, actions by our competitors to increase their revenues can have an adverse impact on the Company’s revenues.
	The Company’s operating results are materially impacted by changes in the availability, price volatility and cost of aircraft fuel, which represents one of the largest single cost items in the Company’s business. Because of the amount of fuel needed to operate the Company’s business, even a relatively small increase in the price of fuel can have a material adverse aggregate effect on the Company’s operating results and liquidity. Jet fuel market prices have fluctuated substantially over the past several years and prices continued to be volatile in 2014.
	These factors could impact the Company’s results of operations, financial performance and liquidity.
	(a) Fuel Price Risk Management
	During the second quarter of 2014, the Company sold its portfolio of fuel hedging contracts that were scheduled to settle on or after June 30, 2014. The Company has not entered into any transactions to hedge its fuel consumption since December 9, 2013 and, accordingly, as of December 31, 2014, the Company did not have any fuel hedging contracts outstanding. As such, and assuming the Company does not enter into any future transactions to hedge its fuel consumption, the Company will continue to be fully exposed to fluctuations in fuel prices. The Company’s current policy is not to enter into transactions to hedge its fuel consumption, although the Company reviews that policy from time to time based on market conditions and other factors.
	The cash proceeds on these sales totaled $71 million which exceeded the current value of the portfolio. Approximately $25 million of the resulting gain was recorded to OCI and will be recognized as a decrease to fuel expense in the period the hedged fuel is scheduled to be consumed (through the second quarter of 2015). As of December 31, 2014, the Company expects to recognize the remaining $9 million of these gains into earnings in 2015. For the years ended December 31, 2014, 2013 and 2012, the Company recognized net gains of approximately $16 million, net losses of approximately $12 million and net gains of approximately $4 million, respectively, as a component of aircraft fuel expense on the accompanying consolidated statements of operations related to its fuel hedging agreements, including the ineffective portion of the hedges.
	The impact of aircraft fuel derivative instruments (all cash flow hedges) on the Company’s consolidated statements of operations is depicted below (in millions):

	While certain of the Company’s fuel derivatives were subject to enforceable master netting agreements with its counterparties, the Company did not offset its fuel derivative assets and liabilities in its consolidated balance sheets. The Company had a gross asset of $109 million as of December 31, 2013 for its aircraft fuel derivative instruments, which was reflected in prepaid expenses and other on the accompanying consolidated balance sheet. The Company had no cash collateral posted or received as of December 31, 2013.
	(b) Credit Risk
	Most of the Company’s receivables relate to tickets sold to individual passengers through the use of major credit cards or to tickets sold by other airlines and used by passengers on American, US Airways or the Company’s regional carriers. These receivables are short-term, mostly being settled within seven days after sale. Bad debt losses, which have been minimal in the past, have been considered in establishing allowances for doubtful accounts. The Company does not believe it is subject to any significant concentration of credit risk.
	(c) Interest Rate Risk
	The Company has exposure to market risk associated with changes in interest rates related primarily to its variable rate debt obligations. Interest rates on $6.5 billion principal amount of long-term debt as of December 31, 2014 are subject to adjustment to reflect changes in floating interest rates. The weighted average effective interest rate on the Company’s variable rate debt was 3.3% at December 31, 2014.

	All short-term investments are classified as available-for-sale and stated at fair value. Unrealized gains and losses are reflected as a component of accumulated other comprehensive income (loss).
	Assets and Liabilities Measured at Fair Value on a Recurring Basis
	The Company utilizes the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. The Company’s short-term investments classified as Level 2 primarily utilize broker quotes in a non-active market for valuation of these securities. The Company’s fuel derivative contracts, which consisted primarily of call options, collars (consisting of a purchased call option and a sold put option) and call spreads (consisting of a purchased call option and a sold call option), are valued using energy and commodity market data which is derived by combining raw inputs with quantitative models and processes to generate forward curves and volatilities. Heating oil, jet fuel and crude oil were the primary underlying commodities in the hedge portfolio. No changes in valuation techniques or inputs occurred during the year ended December 31, 2014.

	Venezuela Cash and Short-term Investments
	As of December 31, 2014, $804 million of the Company’s cash and short-term investments balances were held in foreign bank accounts, of which approximately $656 million was held in Venezuelan bolivars. This balance includes approximately $621 million valued at 6.3 bolivars and approximately $35 million valued at 12.0 bolivars, with the rate depending on the date the Company submitted its repatriation request to the Venezuelan government. These rates are materially more favorable than the exchange rates currently prevailing for other transactions conducted outside of the Venezuelan government’s currency exchange system that the Company participates in. The Company’s cash balance held in Venezuelan bolivars decreased $54 million from the December 31, 2013 balance of $710 million primarily due to $88 million in cash repatriations and $30 million in foreign currency losses as described below, partially offset by additional cash proceeds from ticket sales in early 2014. In the second and third quarters of 2014, the Company repatriated $65 million including $31 million valued at 6.3 bolivars to the dollar and $34 million valued at 10.6 bolivars to the dollar. In the fourth quarter of 2014, the Company incurred an $11 million foreign currency loss related to the receipt of $23 million at a rate of 6.3 bolivars to the dollar for one of its 2012 repatriation requests originally valued at a rate of 4.3 bolivars to the dollar. Accordingly, the Company revalued its remaining pending 2012 repatriation requests from 4.3 to 6.3 bolivars to the dollar resulting in additional foreign currency losses of $19 million. In total, the Company recognized a $30 million special charge for these foreign currency losses in the fourth quarter of 2014. During 2014, the Company significantly reduced capacity in this market and is no longer accepting bolivars as payment for airline tickets. The Company is continuing to work with Venezuelan authorities regarding the timing and exchange rate applicable to the repatriation of funds held in local currency. The Company is monitoring this situation closely and continues to evaluate its holdings of Venezuelan bolivars for additional foreign currency losses, which could be material, particularly in light of the uncertainty posed by the new foreign exchange regulations announced in mid-February 2015 and the continued deterioration of economic conditions in Venezuela. See Part I, Item 1A. Risk Factors – “We operate a global business with international operations that are subject to economic and political instability and have been, and in the future may continue to be, adversely affected by numerous events, circumstances or government actions beyond our control” for unaudited additional discussion of this and other currency risks.
	Fair Value of Debt
	The fair value of the Company’s long-term debt was estimated using quoted market prices or discounted cash flow analyses, based on the Company’s current estimated incremental borrowing rates for similar types of borrowing arrangements. If the Company’s long-term debt was measured at fair value, it would have been classified as Level 2 in the fair value hierarchy.
	The carrying value and estimated fair value of the Company’s long-term debt, including current maturities, were as follows (in millions):

	Assets and Liabilities Measured at Fair Value on a Recurring Basis
	American utilizes the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. American’s short-term investments classified as Level 2 primarily utilize broker quotes in a non-active market for valuation of these securities. American’s fuel derivative contracts, which consisted primarily of call options, collars (consisting of a purchased call option and a sold put option) and call spreads (consisting of a purchased call option and a sold call option), are valued using energy and commodity market data which is derived by combining raw inputs with quantitative models and processes to generate forward curves and volatilities. Heating oil, jet fuel and crude oil were the primary underlying commodities in the hedge portfolio. No changes in valuation techniques or inputs occurred during the year ended December 31, 2014.
	Assets and liabilities measured at fair value on a recurring basis are summarized below (in millions):

	A $56 million Level 1 restricted money market security was liquidated in August 2013. The cash proceeds were subsequently reinvested in a Level 2 U.S. Treasury Obligation. American’s policy regarding the recording of transfers between levels is to reflect any such transfers at the end of the reporting period.
	Venezuela Cash and Short-term Investments
	As of December 31, 2014, $745 million of American’s cash and short-term investments balances were held in foreign bank accounts, of which approximately $656 million was held in Venezuelan bolivars. This balance includes approximately $621 million valued at 6.3 bolivars and approximately $35 million valued at 12.0 bolivars, with the rate depending on the date American submitted its repatriation request to the Venezuelan government. These rates are materially more favorable than the exchange rates currently prevailing for other transactions conducted outside of the Venezuelan government’s currency exchange system that American participates in. American’s cash balance held in Venezuelan bolivars decreased $54 million from the December 31, 2013 balance of $710 million primarily due to $88 million in cash repatriations and $30 million in foreign currency losses as described below, partially offset by additional cash proceeds from ticket sales in early 2014. In the second and third quarters of 2014, American repatriated $65 million including $31 million valued at 6.3 bolivars to the dollar and $34 million valued at 10.6 bolivars to the dollar. In the fourth quarter of 2014, American incurred an $11 million foreign currency loss related to the receipt of $23 million at a rate of 6.3 bolivars to the dollar for one of its 2012 repatriation requests originally valued at a rate of 4.3 bolivars to the dollar. Accordingly, American revalued its remaining pending 2012 repatriation requests from 4.3 to 6.3 bolivars to the dollar resulting in additional foreign currency losses of $19 million. In total, American recognized a $30 million special charge for these foreign currency losses in the fourth quarter of 2014. During 2014, American significantly reduced capacity in this market and is no longer accepting bolivars as payment for airline tickets. American is continuing to work with Venezuelan authorities regarding the timing and exchange rate applicable to the repatriation of funds held in local currency. American is monitoring this situation closely and continues to evaluate its holdings of Venezuelan bolivars for additional foreign currency losses, which could be material, particularly in light of the uncertainty posed by the new foreign exchange regulations announced in mid-February 2015 and the continued deterioration of economic conditions in Venezuela.

Weighted-average assumptions used to determine benefit obligations as of December 31:

Expected return on plan assets			8	%		8	%		8	%		8	%
As of December 31, 2014, the Company’s estimate of the long-term rate of return on plan assets was 8.00% based on the target asset allocation. Expected returns on longer duration bonds are based on yields to maturity of the bonds held at year-end. Expected returns on other assets are based on a combination of long-term historical returns, actual returns on plan assets achieved over the last ten years, current and expected market conditions, and expected value to be generated through active management, currency overlay and securities lending programs. The Company’s annualized ten-year rate of return on plan assets as of December 31, 2014, was approximately 8%.
The objectives of the Company’s investment policies are to: maintain sufficient income and liquidity to pay retirement benefits; produce a long-term rate of return that meets or exceeds the assumed rate of return for plan assets; limit the volatility of asset performance and funded status; and diversify assets among asset classes and investment managers.
Based on these investment objectives, a long-term strategic asset allocation has been established. This strategic allocation seeks to balance the potential benefit of improving funded position with the potential risk that the funded position would decline. The current strategic target asset allocation is as follows:
Asset Class/Sub-Class		Allowed Range
Equity			62% - 72%
Public:
U.S. Value			20% - 35%
International Value			14% - 24%
Emerging Markets			5% - 11%
Alternative Investments			0% - 18%
Fixed Income			28% - 38%
U.S. Long Duration			26% - 36%
Emerging Markets			0% -   4%
Other			0% -   5%
Cash Equivalents			0% -   5%
Each asset class is actively managed and, historically, the plans’ assets have produced returns, net of management fees, in excess of the expected rate of return over the last ten years. Public equity and emerging market fixed income securities are used to provide diversification and are expected to generate higher returns over the long-term than longer duration U.S. bonds. Public stocks are managed using a value investment approach in order to participate in the returns generated by stocks in the long-term, while reducing year-over-year volatility. Longer duration U.S. bonds are used to partially hedge the assets from declines in interest rates. Alternative (private) investments are used to provide expected returns in excess of the public markets over the long-term. Additionally, the Company engages currency overlay managers in an attempt to increase returns by protecting non-U.S. dollar denominated assets from a rise in the relative value of the U.S. dollar. The Company also participates in securities lending programs to generate additional income by loaning plan assets to borrowers on a fully collateralized basis. These programs are subject to market risk.
Investments in securities traded on recognized securities exchanges are valued at the last reported sales price on the last business day of the year. Securities traded in the over-the-counter market are valued at the last bid price. The money market fund is valued at fair value which represents the net asset value of the shares of such fund as of the close of business at the end of the period. Investments in limited partnerships are carried at estimated net asset value as determined by and reported by the general partners of the partnerships and represent the proportionate share of the estimated fair value of the underlying assets of the limited partnerships. Common/collective trusts are valued at net asset value based on the fair values of the underlying investments of the trusts as determined by the sponsor of the trusts. The 103-12 investment trust is valued at net asset value which is determined by the issuer at the end of each month and is based on the aggregate fair value of trust assets less liabilities, divided by the number of units outstanding. No changes in valuation techniques or inputs occurred during the year.

Investments in the AMR Class shares of the mutual funds managed by American Beacon Advisors, Inc (ABA) are valued by quoted prices on the active market, which is fair value and represents the net asset value of the shares of such funds as of the close of business at the end of the period. AMR Class shares are offered without a sales charge to participants and have the lowest expense ratio among the Beacon Funds. Purchases are restricted to retirement benefit plans of ABA and AMR and its affiliates, resulting in a fair value classification of Level 2. Investments include approximately 28% of investments in non-U.S. common stocks in 2014 and 27% of investments in non-U.S. common stocks in 2013. Net asset value is based on the fair market value of the funds’ underlying assets and liabilities at the date of determination.

The Company is required to make minimum contributions to its defined benefit pension plans under the minimum funding requirements of the Employee Retirement Income Security Act of 1974 (ERISA), the Pension Funding Equity Act of 2004, the Pension Protection Act of 2006, the Pension Relief Act of 2010 and the Moving Ahead for Progress in the 21st Century Act of 2012. In 2014, the Company has made its aggregate minimum required contributions for 2014 of $171 million, and has made $639 million in supplemental contributions to its pension plans, above and beyond the $171 million of minimum required contributions.
Based on current funding assumptions, the Company has no minimum required contributions until 2019. Currently, American’s minimum funding obligation for its pension plans is subject to temporary favorable rules that are scheduled to expire at the end of 2017. Upon expiration of these rules, American’s funding obligations are likely to increase materially.
The following benefit payments, which reflect expected future service as appropriate, are expected to be paid (in millions):

Modifications to Retirement and Life Insurance Benefits
Effective November 1, 2012, the Company’s defined benefit pension plans were frozen and the Company began providing enhanced benefits under the $uper $aver 401(k) Plan for certain groups. Effective November 1, 2012, the Company matches all non-flight crew employee contributions up to 5.5% of eligible earnings. Effective November 1, 2012 through December 31, 2013, pilots received employer contributions of 14% of eligible earnings and flight attendants received matching contributions of up to 5.5% of eligible earnings. With the ratification of a new CBA by pilots on December 9, 2013, effective January 1, 2014, pilots receive employer contributions of 16% of eligible earnings. With the 2013 Conditional Labor Agreement, effective January 1, 2014, flight attendants on the American seniority list as of April 12, 2012 receive age-based employer contributions (under age 40 – 5.5% of eligible earnings; age 40 to 49 – 6.75% of eligible earnings; and age 50 and above – 9.9% of eligible earnings) and flight attendants hired after April 12, 2012, receive employer contributions of 3% of eligible earnings plus company matching contributions of up to 2.5% of eligible earnings.
In December 2012, the Pilot A Plan, a defined benefit plan, was amended to remove the lump-sum option and the installment option forms of benefit effective December 31, 2012. A small group of American pilots is appealing the Bankruptcy Court’s decision authorizing American to eliminate the lump sum option and installment option forms of benefit. This is the same group of pilots that are appealing the Bankruptcy Court’s decisions authorizing American to reject the pilot CBA and approve the new pilot CBA. The U.S. District Court for the Southern District of New York upheld the Bankruptcy Court decision. The appeals currently are pending in the U.S. Court of Appeals for the Second Circuit.
The Pilot B Plan, a defined contribution plan, was terminated on November 30, 2012. With the exception of a small residual balance to cover final plan expenses, the Company has distributed all of the funds in the plan.
On July 6, 2012, the Company commenced an adversary proceeding in the Bankruptcy Court seeking a determination on the issue of vesting for former employees who retired before November 1, 2012 and were eligible for certain retiree medical coverage. The Bankruptcy Court granted in part and denied in part the Company’s motion for summary judgment concerning vesting.
As a result of the modifications to the retirement benefits as discussed above, a portion of the pension and postretirement benefits liability, primarily relating to retiree medical and other benefits, was classified as liabilities subject to compromise as of December 31, 2012. This amount was reinstated upon emergence since there was no resolution in the Chapter 11 Cases.
Curtailment and Plan Amendment in the Third Quarter of 2012
In accordance with ASC 715 “Retirement Benefits” (ASC 715), in the third quarter of 2012, the Company remeasured its defined benefit pension and retiree medical plans as a result of modifications to its retirement plans and reductions in certain work groups (see above and Note 2 to AAG’s consolidated financial statements). The Company updated its significant actuarial assumptions used for the remeasurements including the discount rate, which was lowered to 4.10% and 3.80% for the defined benefit pension plans and retiree medical plans, respectively.
The remeasurement of the defined benefit plans resulted in an actuarial loss of $1.9 billion offset by a curtailment gain of $1.8 billion. In addition, a loss of $58 million, representing unamortized prior service cost as of the remeasurement date of the frozen defined benefit plans, is included as a component of reorganization items, net.
Further, as a result of modifications to its retiree medical plans, the Company recognized a negative plan amendment of $1.9 billion, which is included as a component of actuarial gain arising in current year in other comprehensive income and will be amortized over the future service life of the active plan participants for whom the benefit was eliminated, or approximately eight years. In addition, a net credit of $124 million, representing unamortized prior service credits of $157 million offset by a curtailment loss of $33 million, is included as a component of reorganization items, net.

Retirement Benefits	10. Retirement Benefits
	American sponsors defined benefit and defined contribution pension plans for eligible employees. The defined benefit plans provide benefits for participating employees based on years of service and average compensation for a specified period of time before retirement. American uses a December 31 measurement date for all of its defined benefit plans. In addition, American provides certain postemployment benefits to its employees. These benefits include disability-related and workers’ compensation benefits for certain employees. American accrues for the cost of such benefit expenses once an appropriate triggering event has occurred.

	Weighted-average assumptions used to determine benefit obligations as of December 31:

Expected return on plan assets			8	%		8	%		8	%		8	%
As of December 31, 2014, American’s estimate of the long-term rate of return on plan assets was 8.00% based on the target asset allocation. Expected returns on longer duration bonds are based on yields to maturity of the bonds held at year-end. Expected returns on other assets are based on a combination of long-term historical returns, actual returns on plan assets achieved over the last ten years, current and expected market conditions, and expected value to be generated through active management, currency overlay and securities lending programs. American’s annualized ten-year rate of return on plan assets as of December 31, 2014, was approximately 8%.
The objectives of American’s investment policies are to: maintain sufficient income and liquidity to pay retirement benefits; produce a long-term rate of return that meets or exceeds the assumed rate of return for plan assets; limit the volatility of asset performance and funded status; and diversify assets among asset classes and investment managers.
Based on these investment objectives, a long-term strategic asset allocation has been established. This strategic allocation seeks to balance the potential benefit of improving funded position with the potential risk that the funded position would decline. The current strategic target asset allocation is as follows:
Asset Class/Sub-Class		Allowed Range
Equity			62% - 72	%
Public:
U.S. Value			20%  - 35	%
International Value			14%  - 24	%
Emerging Markets			5%  - 11	%
Alternative Investments			0%  - 18	%
Fixed Income			28%  - 38	%
U.S. Long Duration			26%  - 36	%
Emerging Markets			0%  - 4	%
Other			0%  - 5	%
Cash Equivalents			0%  - 5	%
Each asset class is actively managed and, historically, the plans’ assets have produced returns, net of management fees, in excess of the expected rate of return over the last ten years. Public equity and emerging market fixed income securities are used to provide diversification and are expected to generate higher returns over the long-term than longer duration U.S. bonds. Public stocks are managed using a value investment approach in order to participate in the returns generated by stocks in the long-term, while reducing year-over-year volatility. Longer duration U.S. bonds are used to partially hedge the assets from declines in interest rates. Alternative (private) investments are used to provide expected returns in excess of the public markets over the long-term. Additionally, American engages currency overlay managers in an attempt to increase returns by protecting non-U.S. dollar denominated assets from a rise in the relative value of the U.S. dollar. American also participates in securities lending programs to generate additional income by loaning plan assets to borrowers on a fully collateralized basis. These programs are subject to market risk.
Investments in securities traded on recognized securities exchanges are valued at the last reported sales price on the last business day of the year. Securities traded in the over-the-counter market are valued at the last bid price. The money market fund is valued at fair value which represents the net asset value of the shares of such fund as of the close of business at the end of the period. Investments in limited partnerships are carried at estimated net asset value as determined by and reported by the general partners of the partnerships and represent the proportionate share of the estimated fair value of the underlying assets of the limited partnerships. Common/collective trusts are valued at net asset value based on the fair values of the underlying investments of the trusts as determined by the sponsor of the trusts. The 103-12 investment trust is valued at net asset value which is determined by the issuer at the end of each month and is based on the aggregate fair value of trust assets less liabilities, divided by the number of units outstanding. No changes in valuation techniques or inputs occurred during the year.

American is required to make minimum contributions to its defined benefit pension plans under the minimum funding requirements of the Employee Retirement Income Security Act of 1974 (ERISA), the Pension Funding Equity Act of 2004, the Pension Protection Act of 2006, the Pension Relief Act of 2010 and the Moving Ahead for Progress in the 21st Century Act of 2012. In 2014, American has made its aggregate minimum required contributions for 2014 of $170 million, and has made $639 million in supplemental contributions to its pension plans, above and beyond the $170 million of minimum required contributions.
Based on current funding assumptions, American has no minimum required contributions until 2019. Currently, American’s minimum funding obligation for its pension plans is subject to temporary favorable rules that are scheduled to expire at the end of 2017. Upon expiration of these rules, American’s funding obligations are likely to increase materially.

Effective November 1, 2012, American’s defined benefit pension plans were frozen and American began providing enhanced benefits under the $uper $aver 401(k) Plan for certain groups. Effective November 1, 2012, American matches all non-flight crew employee contributions up to 5.5% of eligible earnings. Effective November 1, 2012 through December 31, 2013, pilots received employer contributions of 14% of eligible earnings and flight attendants received matching contributions of up to 5.5% of eligible earnings. With the ratification of a new CBA by pilots on December 9, 2013, effective January 1, 2014, pilots receive employer contributions of 16% of eligible earnings. With the 2013 Conditional Labor Agreement, effective January 1, 2014, flight attendants on the American seniority list as of April 12, 2012 receive age-based employer contributions (under age 40 – 5.5% of eligible earnings; age 40 to 49 – 6.75% of eligible earnings; and age 50 and above – 9.9% of eligible earnings) and flight attendants hired after April 12, 2012, receive employer contributions of 3% of eligible earnings plus company matching contributions of up to 2.5% of eligible earnings.
In December 2012, the Pilot A Plan, a defined benefit plan, was amended to remove the lump-sum option and the installment option forms of benefit effective December 31, 2012. A small group of American pilots is appealing the Bankruptcy Court’s decision authorizing American to eliminate the lump sum option and installment option forms of benefit. This is the same group of pilots that are appealing the Bankruptcy Court’s decisions authorizing American to reject the pilot CBA and approve the new pilot CBA. The U.S. District Court for the Southern District of New York upheld the Bankruptcy Court decision. The appeals currently are pending in the U.S. Court of Appeals for the Second Circuit.
The Pilot B Plan, a defined contribution plan, was terminated on November 30, 2012. With the exception of a small residual balance to cover final plan expenses, American has distributed all of the funds in the plan.
On July 6, 2012, American commenced an adversary proceeding in the Bankruptcy Court seeking a determination on the issue of vesting for former employees who retired before November 1, 2012 and were eligible for certain retiree medical coverage. The Bankruptcy Court granted in part and denied in part American’s motion for summary judgment concerning vesting.
As a result of the modifications to the retirement benefits as discussed above, a portion of the pension and postretirement benefits liability, primarily relating to retiree medical and other benefits, was classified as liabilities subject to compromise as of December 31, 2012. This amount was reinstated upon emergence since there was no resolution in the Chapter 11 Cases.
Curtailment and Plan Amendment in the Third Quarter of 2012
In accordance with ASC 715 “Retirement Benefits” (ASC 715), in the third quarter of 2012, American remeasured its defined benefit pension and retiree medical plans as a result of modifications to its retirement plans and reductions in certain work groups (see above and Note 2 to American’s consolidated financial statements). American updated its significant actuarial assumptions used for the remeasurements including the discount rate, which was lowered to 4.10% and 3.80% for the defined benefit pension plans and retiree medical plans, respectively.
The remeasurement of the defined benefit plans resulted in an actuarial loss of $1.9 billion offset by a curtailment gain of $1.8 billion. In addition, a loss of $58 million, representing unamortized prior service cost as of the remeasurement date of the frozen defined benefit plans, is included as a component of reorganization items, net.
Further, as a result of modifications to its retiree medical plans, American recognized a negative plan amendment of $1.9 billion, which is included as a component of actuarial gain arising in current year in other comprehensive income and will be amortized over the future service life of the active plan participants for whom the benefit was eliminated, or approximately eight years. In addition, a net credit of $124 million, representing unamortized prior service credits of $157 million offset by a curtailment loss of $33 million, is included as a component of reorganization items, net.

	-1	These amounts are net of purchase deposits currently held by the manufacturers and include all commitments for regional aircraft. American has granted Boeing a security interest in its purchase deposits with Boeing. The Company’s purchase deposits totaled $1.2 billion as of December 31, 2014.
	In April 2014, the Company exercised its option to purchase and terminated its existing lease financing arrangements with respect to 62 Airbus A320 family aircraft scheduled to be delivered between the first quarter of 2015 and the third quarter of 2017. In connection with the Company’s exercise of such option, the Company also exercised its right to convert firm orders for 30 Airbus A320neo aircraft, scheduled to be delivered in 2021 and 2022, to options to acquire such aircraft. The table above reflects these changes.
	In December 2014, the Company exercised its right under its purchase agreement with Bombardier to convert 24 of the Company’s 40 option order CRJ900 aircraft to firm orders to acquire such aircraft.
	(b) Facility and support commitments
	The Company has contracts related to facility construction or improvement projects, primarily at airport locations as well as information technology support. The contractual obligations related to these contracts are presented in the table below (in millions):

	(c) Capacity Purchase Agreements with Third-Party Regional Carriers
	As of December 31, 2014, the Company’s capacity purchase agreements with third-party regional carriers had expiration dates ranging from 2015 to 2027, with rights of American or US Airways, respectively, to extend the respective terms of each agreement. See Part I, Item 2. Properties for unaudited information on the aircraft contractually obligated to the Company under such capacity purchase agreements with third-party regional carriers.
	The Company has entered into agreements with the third-party regional carriers that operate certain of their aircraft using American’s or US Airways’ flight designator codes. American or US Airways, respectively, controls the scheduling, pricing, reservations, ticketing and seat inventories of those aircraft and retains all revenues associated with revenue flights by those aircraft. American or US Airways pays the third-party regional carriers an amount, as defined in the applicable agreement, based on the airlines’ costs of operating those flights and other factors intended to approximate market rates for those services. As of December 31, 2014, the Company’s minimum fixed obligations under its capacity purchase agreements with third-party regional airlines were as follows (approximately, in millions):
			2015		2016		2017		2018		2019		2020 and		Total

	Minimum fixed obligations under its capacity purchase agreements with third-party regional carriers (1)		$	1,584	$	1,616	$	1,479	$	1,197	$	1,066	$	3,102	$	10,044
	-1	Represents minimum payments under capacity purchase agreements with third-party regional carriers. These commitments are estimates of costs based on assumed minimum levels of flying under the capacity purchase agreements and the Company’s actual payments could differ materially. These obligations also include the portion of the Company’s future obligations related to aircraft deemed to be leased in the amount of approximately $492 million in 2015, $446 million in 2016, $382 million in 2017, $316 million in 2018, $283 million in 2019 and $883 million in 2020 and thereafter.
	(d) Operating Leases
	The Company leases certain aircraft, engines and ground equipment, in addition to the majority of its ground facilities and terminal space. As of December 31, 2014, the Company had 477 aircraft under operating leases, with remaining terms ranging from one month to approximately 13 years. Airports are utilized for flight operations under lease arrangements with the municipalities or agencies owning or controlling such airports. Substantially all leases provide that the lessee must pay taxes, maintenance, insurance and certain other operating expenses applicable to the leased property. Some leases also include renewal and purchase options.
	As of December 31, 2014, obligations under noncancellable operating leases for future minimum lease payments were as follows (in millions):
			2015		2016		2017		2018		2019		2020 and		Total
													Thereafter
	Future minimum lease payments (1)		$	2,110	$	1,917	$	1,809	$	1,558	$	1,399	$	5,721	$	14,514
	-1	As of December 31, 2014, $267 million is included on the accompanying balance sheet in accrued liabilities and deferred gains and credits, net relating to rent expense being recorded in advance of future operating lease payments.
	Rent expense, excluding landing fees, was $2.8 billion, $1.7 billion and $1.4 billion in 2014, 2013 and 2012, respectively.
	(e) Off-Balance Sheet Arrangements
	Aircraft
	AAG has 214 owned aircraft and 138 leased aircraft which were financed with pass through trust certificates, or EETCs, issued by pass through trusts. These trusts are off-balance sheet entities, the primary purpose of which is to finance the acquisition of flight equipment. Rather than finance each aircraft separately when such aircraft was purchased, delivered or refinanced, these trusts allowed AAG to raise the financing for several aircraft at one time and place such funds in escrow pending the purchase, delivery or refinancing of the relevant aircraft. The trusts were also structured to provide for certain credit enhancements, such as liquidity facilities to cover certain interest payments, that reduce the risks to the purchasers of the trust certificates and, as a result, reduce the cost of aircraft financing to AAG.
	Each trust covered a set amount of aircraft scheduled to be delivered or refinanced within a specific period of time. At the time of each covered aircraft financing, the relevant trust used the funds in escrow to purchase equipment notes relating to the financed aircraft. The equipment notes were issued, at AAG’s election, in connection with a mortgage financing of the aircraft or, in certain cases, by a separate owner trust in connection with a leveraged lease financing of the aircraft. In the case of a leveraged lease financing, the owner trust then leased the aircraft to American or US Airways, as applicable. In both cases, the equipment notes are secured by a security interest in the aircraft. The pass through trust certificates are not direct obligations of, nor are they guaranteed by AAG, American, US Airways Group or US Airways. However, in the case of mortgage financings, the equipment notes issued to the trusts are direct obligations of American or US Airways and in certain instances are guaranteed by AAG or US Airways Group, as applicable. As of December 31, 2014, $7.0 billion associated with these mortgage financings is reflected as debt in the accompanying consolidated balance sheet.
	With respect to leveraged leases, AAG evaluated whether the leases had characteristics of a variable interest entity and concluded the leasing entities met the criteria for variable interest entities. AAG generally is not the primary beneficiary of the leasing entities if the lease terms are consistent with market terms at the inception of the lease and do not include a residual value guarantee, fixed-price purchase option or similar feature that obligates AAG to absorb decreases in value or entitles AAG to participate in increases in the value of the aircraft. AAG does not provide residual value guarantees to the bondholders or equity participants in the trusts. Some leases have a fair market value or a fixed price purchase option that allows AAG to purchase the aircraft at or near the end of the lease term. However, the option price approximates an estimate of the aircraft’s fair value at the option date. Under this feature, AAG does not participate in any increases in the value of the aircraft. AAG concluded it was not the primary beneficiary under these arrangements. Therefore, AAG accounts for its EETC leveraged lease financings as operating leases. AAG’s total future obligations under these leveraged lease financings are $2.1 billion as of December 31, 2014, which are included in the future minimum lease payments table above.
	Special Facility Revenue Bonds
	AAG guarantees the payment of principal and interest of certain special facility revenue bonds issued by municipalities primarily to build or improve airport facilities and purchase equipment which is leased to AAG. Under such leases, AAG is required to make rental payments through 2035, sufficient to pay maturing principal and interest payments on the related bonds. As of December 31, 2014, the remaining lease payments guaranteeing the principal and interest on these bonds are $449 million, which are accounted for as operating leases.
	(f) Legal Proceedings
	Chapter 11 Cases. As previously disclosed, on the Petition Date, November 29, 2011, the Debtors filed the Chapter 11 Cases. On October 21, 2013, the Bankruptcy Court entered the Confirmation Order confirming the Plan. On the Effective Date, December 9, 2013, the Debtors consummated their reorganization pursuant to the Plan, principally through the transactions contemplated by the Merger Agreement pursuant to which Merger Sub merged with and into US Airways Group, with US Airways Group surviving as a wholly-owned subsidiary of AAG. From the Petition Date through the Effective Date, pursuant to automatic stay provisions under the Bankruptcy Code and orders granted by the Bankruptcy Court, actions to enforce or otherwise effect repayment of liabilities preceding the Petition Date as well as all pending litigation against the Debtors generally were stayed. Following the Effective Date, actions to enforce or otherwise effect repayment of liabilities preceding the Petition Date, generally have been permanently enjoined. Any unresolved claims will continue to be subject to the claims reconciliation process under the supervision of the Bankruptcy Court. However, certain pending litigation related to pre-petition liabilities may proceed in courts other than the Bankruptcy Court to determine the amount, if any, of such litigation claims for purposes of treatment under the Plan.
	Pursuant to rulings of the Bankruptcy Court, the Plan established the Disputed Claims Reserve to hold shares of AAG Common Stock reserved for issuance to disputed claimholders at the Effective Date that ultimately become holders of allowed Single-Dip Unsecured Claims. The shares provided for under the Plan were determined based upon a Disputed Claims Reserve amount of claims of approximately $755 million, representing the maximum amount of additional distributions to subsequently allowed Single-Dip Unsecured Claims under the Plan. On July 1, 2014 (the date 180 days after the Effective Date), approximately 2.9 million shares of AAG Common Stock held in the Disputed Claims Reserve were distributed to holders of allowed Single-Dip Unsecured Claims, to holders of certain labor-related deemed claims, and to holders of certain non-management, non-union employee deemed claims as specified in the Plan, and shares were withheld or sold on account of related tax obligations. In addition, on July 1, 2014, the Company repurchased 0.4 million shares of AAG Common Stock for an aggregate of $19 million from the Disputed Claims Reserve at the then prevailing market price in order to fund cash tax obligations resulting from distributions by the Disputed Claims Reserve. On November 4, 2014, approximately 0.7 million shares of AAG Common Stock held in the Disputed Claims Reserve were distributed to holders of allowed Single-Dip Unsecured Claims, to holders of certain labor-related deemed claims, and to holders of certain non-management, non-union employee deemed claims as specified in the Plan, and shares were withheld or sold on account of related tax obligations. In addition, on November 4, 2014, the Company repurchased less than 0.1 million shares of AAG Common Stock for an aggregate of $2 million from the Disputed Claims Reserve at the then prevailing market price in order to fund cash tax obligations resulting from distributions by the Disputed Claims Reserve. As of December 31, 2014, there were approximately 26.8 million shares of AAG Common Stock remaining in the Disputed Claims Reserve. On February 10, 2015, approximately 0.8 million shares of AAG Common Stock held in the Disputed Claims Reserve were distributed to holders of allowed Single-Dip Unsecured Claims, to holders of certain labor-related deemed claims, and to holders of certain non-management, non-union employee deemed claims as specified in the Plan, and shares were withheld or sold on account of related tax obligations. In addition, on February 10, 2015, the Company repurchased less than 0.1 million shares of AAG Common Stock for an aggregate of $4 million from the Disputed Claims Reserve at the then prevailing market price in order to fund cash tax obligations resulting from distributions by the Disputed Claims Reserve. As disputed claims are resolved, the claimants will receive distributions of shares from the Disputed Claims Reserve on the same basis as if such distributions had been made on or about the Effective Date. However, the Company is not required to distribute additional shares above the limits contemplated by the Plan, even if the shares remaining for distribution are not sufficient to fully pay any additional allowed unsecured claims. To the extent that any of the reserved shares remain undistributed upon resolution of all remaining disputed claims, such shares will not be returned to the Company but rather will be distributed to former AMR shareholders as of the Effective Date. However, resolution of disputed claims could have a material effect on recoveries by holders of additional allowed Single-Dip Unsecured Claims under the Plan and the amount of additional share distributions, if any, that are made to former AMR shareholders as the total number of shares of AAG Common Stock that remain available for distribution upon resolution of disputed claims is limited pursuant to the Plan.
	There is also pending in the Bankruptcy Court an adversary proceeding relating to an action brought by American to seek a determination that certain non-pension, post-employee benefits (OPEB) are not vested benefits and thus may be modified or terminated without liability to American. On April 18, 2014, the Bankruptcy Court granted American’s motion for summary judgment with respect to certain non-union employees, concluding that their benefits were not vested and could be terminated. The summary judgment motion was denied with respect to all other retirees. The Bankruptcy Court has not yet scheduled a trial on the merits concerning whether those retirees’ benefits are vested, and American cannot predict whether it will receive relief from obligations to provide benefits to any of those retirees. The Company’s financial statements presently reflect these retirement programs without giving effect to any modification or termination of benefits that may ultimately be implemented based upon the outcome of this proceeding. Separately, both the Association of Professional Flight Attendants and Transport Workers Union have filed grievances asserting that American was “successful” in its Chapter 11 with respect to matters related to OPEB and, accordingly, by operation of the underlying collective bargaining agreements, American’s prior contributions to certain OPEB prefunding trusts attributable to active employees should be returned to those active employees. These amounts aggregate approximately $212 million. The Company has denied both grievances and intends to defend these matters vigorously.
	Private Party Antitrust Action. On July 2, 2013, a lawsuit captioned Carolyn Fjord, et al., v. US Airways Group, Inc., et al., was filed in the United States District Court for the Northern District of California. The complaint names as defendants US Airways Group and US Airways, and alleges that the effect of the Merger may be to substantially lessen competition or tend to create a monopoly in violation of Section 7 of the Clayton Antitrust Act. The relief sought in the complaint includes an injunction against the Merger, or divestiture. On August 6, 2013, the plaintiffs re-filed their complaint in the Bankruptcy Court, adding AMR and American as defendants, and on October 2, 2013, dismissed the initial California action. The Bankruptcy Court denied plaintiffs’ motion to preliminarily enjoin the Merger. On January 10, 2014, the plaintiffs moved to amend their complaint to add additional factual allegations, a claim for money damages and a request for preliminary injunctive relief requiring the carriers to hold separate their assets. On March 14, 2014, the Court allowed plaintiffs to add certain allegations but denied plaintiffs’ requests to add a damages claim or seek preliminary injunctive relief requiring the carriers to hold separate their assets. On June 2, 2014, plaintiffs filed an amended motion for leave to file a second amended and supplemental complaint, which motion has been fully briefed by the parties and is pending resolution by the Court. There is currently no trial date set. The Company believes this lawsuit is without merit and intends to vigorously defend against the allegations.
	US Airways Sabre Matter. On April 21, 2011, US Airways filed an antitrust lawsuit against Sabre Holdings Corporation, Sabre Inc. and Sabre Travel International Limited (collectively, Sabre) in the Federal District Court for the Southern District of New York. The lawsuit, as amended to date, alleges, among other things, that Sabre has engaged in anticompetitive practices to preserve its market power by restricting the Company’s ability to distribute its products to its customers. The lawsuit also alleges that these actions have permitted Sabre to charge supracompetitive booking fees and to use technologies that are not as robust and as efficient as alternatives in a competitive market. The lawsuit seeks money damages. Sabre filed a motion to dismiss the case, which the court denied in part and granted in part in September 2011, allowing two of the four counts in the complaint to proceed. In January 2015, the court denied in part and granted in part Sabre’s motions for summary judgment. A trial date is expected to be set soon. The Company intends to pursue its claims against Sabre vigorously, but there can be no assurance of the outcome of this litigation.
	General. The Company and its subsidiaries are also engaged in other legal proceedings from time to time. Legal proceedings can be complex and take many months, or even years, to reach resolution, with the final outcome depending on a number of variables, some of which are not within the control of the Company. Therefore, although the Company will vigorously defend itself in each of the actions described above and such other legal proceedings, their ultimate resolution and potential financial and other impacts on the Company are uncertain.
	(g) Guarantees and Indemnifications
	US Airways assigned to Delta a lease agreement with the Port Authority of New York and New Jersey (the Port Authority) related to the East End Terminal at LaGuardia airport. A portion of the rental payments under the lease are used to repay special facility revenue bonds issued by the Port Authority. The special facility revenue bonds have a final scheduled maturity in 2015 and had an outstanding principal amount of approximately $22 million at December 31, 2014. Pursuant to the terms of the lease assignment, US Airways is contingently liable for Delta’s obligations, as assignee, under the lease agreement in the event Delta fails to perform such obligations including, without limitation, the payment of all rentals and other amounts due under the lease agreement. US Airways has the right to cure any failure by Delta to perform its obligations under the lease agreement and, in addition, US Airways has the right to reoccupy the terminal if it so chooses to cure any such default.
	The Company is a party to many routine contracts in which it provides general indemnities in the normal course of business to third parties for various risks. The Company is not able to estimate the potential amount of any liability resulting from the indemnities. These indemnities are discussed in the following paragraphs.
In its aircraft financing agreements, the Company generally indemnifies the financing parties, trustees acting on their behalf and other relevant parties against liabilities (including certain taxes) resulting from the financing, manufacture, design, ownership, operation and maintenance of the aircraft regardless of whether these liabilities (or taxes) relate to the negligence of the indemnified parties.
The Company’s loan agreements and other London Interbank Offered Rate (LIBOR)-based financing transactions (including certain leveraged aircraft leases) generally obligate the Company to reimburse the applicable lender for incremental costs due to a change in law that imposes (i) any reserve or special deposit requirement against assets of, deposits with or credit extended by such lender related to the loan, (ii) any tax, duty or other charge with respect to the loan (except standard income tax) or (iii) capital adequacy requirements. In addition, the Company’s loan agreements, derivative contracts and other financing arrangements typically contain a withholding tax provision that requires the Company to pay additional amounts to the applicable lender or other financing party, generally if withholding taxes are imposed on such lender or other financing party as a result of a change in the applicable tax law.
These increased cost and withholding tax provisions continue for the entire term of the applicable transaction, and there is no limitation on the maximum additional amounts the Company could be obligated to pay under such provisions. Any failure to pay amounts due under such provisions generally would trigger an event of default and, in a secured financing transaction, would entitle the lender to foreclose on the collateral to realize the amount due.
In certain transactions, including certain aircraft financing leases and loans, the lessors, lenders and/or other parties have rights to terminate the transaction based on changes in foreign tax law, illegality or certain other events or circumstances. In such a case, the Company may be required to make a lump sum payment to terminate the relevant transaction.
The Company has general indemnity clauses in many of its airport and other real estate leases where the Company as lessee indemnifies the lessor (and related parties) against liabilities related to the Company’s use of the leased property. Generally, these indemnifications cover liabilities resulting from the negligence of the indemnified parties, but not liabilities resulting from the gross negligence or willful misconduct of the indemnified parties. In addition, the Company provides environmental indemnities in many of these leases for contamination related to the Company’s use of the leased property.
Under certain contracts with third parties, the Company indemnifies the third-party against legal liability arising out of an action by the third-party, or certain other parties. The terms of these contracts vary and the potential exposure under these indemnities cannot be determined. The Company has liability insurance protecting the Company for some of the obligations it has undertaken under these indemnities.
The Company is involved in certain claims and litigation related to its operations. The Company is also subject to regulatory assessments in the ordinary course of business. The Company establishes reserves for litigation and regulatory matters when those matters present loss contingencies that are both probable and can be reasonably estimated. In the opinion of management, liabilities, if any, arising from these regulatory matters, claims and litigation will not have a material adverse effect on the Company’s consolidated financial position, results of operations, or cash flows, after consideration of available insurance.
(h) Other
In 2010, American and Japan Airlines entered into a JBA under which, amongst other things, American provided Japan Airlines a guarantee of certain minimum incremental revenue resulting from the successful operation of the joint business for the first three years following its implementation, subject to certain terms and conditions. The amount required to be paid by the Company under the guarantee in any one of such years may not exceed $100 million, and is reduced if capacity for one of such years is less than a defined base year period capacity. As of December 31, 2013, American reached an agreement with Japan Airlines to settle the liability for $90 million. The liability is expected to be settled in 2015.
In the fourth quarter of 2012, the Company entered into a settlement agreement resolving a commercial dispute. The settlement agreement includes two elements which were valued at relative fair value and will be recognized when earned. The Company determined that the settlement includes a litigation gain of $280 million, which was valued using future cash flows and recognized in the fourth quarter of 2012. The settlement also includes an incentive which is contingent upon signing a future contract and will be recognized over the term of the future contract. The contract was signed in January 2014. In connection with the new contract, the Company recorded an additional $70 million receivable with an offset to other liabilities to be recognized over the course of the remaining contract term.
As a result of the terrorist attacks of September 11, 2001 (the Terrorist Attacks) and the subsequent liability protections provided for by the Air Transportation Safety and System Stabilization Act (the Stabilization Act), the Company recorded a liability for the Terrorist Attacks claims equal to the related insurance receivable due to American. The Stabilization Act provides that, notwithstanding any other provision of law, liability for all claims, whether compensatory or punitive, arising from the Terrorist Attacks, against any air carrier shall not exceed the liability coverage maintained by the air carrier. As of December 31, 2014, the remaining liability and the amount of the offsetting receivable were each $974 million.

	Information technology contracts			179		139		112		96		79		1		606
	(c) Capacity Purchase Agreements with Third-Party Regional Carriers
	As of December 31, 2014, American’s capacity purchase agreements with third-party regional carriers had expiration dates ranging from 2016 to 2027, with rights of American to extend the respective terms of each agreement. See Part I, Item 2. Properties for unaudited information on the aircraft contractually obligated to American under such capacity purchase agreements with third-party regional carriers.
	American has entered into agreements with the third-party regional carriers that operate certain of their aircraft using American’s flight designator codes. American controls the scheduling, pricing, reservations, ticketing and seat inventories of those aircraft and retains all revenues associated with revenue flights by those aircraft. American pays the third-party regional carriers an amount, as defined in the applicable agreement, based on the airlines’ costs of operating those flights and other factors intended to approximate market rates for those services. As of December 31, 2014, American’s minimum fixed obligations under its capacity purchase agreements with third-party regional carriers were as follows (approximately, in millions):
			2015		2016		2017		2018		2019		2020 and		Total

	Minimum fixed obligations under its capacity purchase agreements with third-party regional carriers (1)		$	502	$	592	$	463	$	446	$	430	$	2,242	$	4,675
	-1	Represents minimum payments under capacity purchase agreements with third-party regional carriers. These commitments are estimates of costs based on assumed minimum levels of flying under the capacity purchase agreements and American’s actual payments could differ materially. These obligations also include the portion of American’s future obligations related to aircraft deemed to be leased in the amount of approximately $173 million in 2015, $171 million in 2016, $111 million in 2017, $107 million in 2018, $107 million in 2019 and $665 million in 2020 and thereafter.
	(d) Operating Leases
	American leases certain aircraft, engines and ground equipment, in addition to the majority of its ground facilities and terminal space. As of December 31, 2014, American had 245 aircraft under operating leases, with remaining terms ranging from one month to approximately 13 years. Airports are utilized for flight operations under lease arrangements with the municipalities or agencies owning or controlling such airports. Substantially all leases provide that the lessee must pay taxes, maintenance, insurance and certain other operating expenses applicable to the leased property. Some leases also include renewal and purchase options.
	As of December 31, 2014, obligations under noncancellable operating leases for future minimum lease payments were as follows (in millions):
			2015		2016		2017		2018		2019		2020 and		Total
													Thereafter
	Future minimum lease payments (1)		$	1,391	$	1,293	$	1,240	$	1,141	$	1,069	$	4,939	$	11,073
	-1	As of December 31, 2014, $231 million is included on the accompanying balance sheet in accrued liabilities and deferred gains and credits, net relating to rent expense being recorded in advance of future operating lease payments.
	Rent expense, excluding landing fees, was $1.8 billion, $1.6 billion and $1.4 billion in 2014, 2013 and 2012 respectively.
	(e) Off-Balance Sheet Arrangements
	Aircraft
	American has 135 owned aircraft and 32 leased aircraft which were financed with pass through trust certificates, or EETCs, issued by pass through trusts. These trusts are off-balance sheet entities, the primary purpose of which is to finance the acquisition of flight equipment. Rather than finance each aircraft separately when such aircraft was purchased, delivered or refinanced, these trusts allowed American to raise the financing for several aircraft at one time and place such funds in escrow pending the purchase, delivery or refinancing of the relevant aircraft. The trusts were also structured to provide for certain credit enhancements, such as liquidity facilities to cover certain interest payments, that reduce the risks to the purchasers of the trust certificates and, as a result, reduce the cost of aircraft financing to American.
	Each trust covered a set amount of aircraft scheduled to be delivered or refinanced within a specific period of time. At the time of each covered aircraft financing, the relevant trust used the funds in escrow to purchase equipment notes relating to the financed aircraft. The equipment notes were issued, at American’s election, in connection with a mortgage financing of the aircraft or, in certain cases, by a separate owner trust in connection with a leveraged lease financing of the aircraft. In the case of a leveraged lease financing, the owner trust then leased the aircraft to American. In both cases, the equipment notes are secured by a security interest in the aircraft. The pass through trust certificates are not direct obligations of, nor are they guaranteed by American. However, in the case of mortgage financings, the equipment notes issued to the trusts are direct obligations of American and in certain instances are guaranteed by AAG. As of December 31, 2014, $4.3 billion associated with these mortgage financings is reflected as debt in the accompanying consolidated balance sheet.
	With respect to leveraged leases, American evaluated whether the leases had characteristics of a variable interest entity and concluded the leasing entities met the criteria for variable interest entities. American generally is not the primary beneficiary of the leasing entities if the lease terms are consistent with market terms at the inception of the lease and do not include a residual value guarantee, fixed-price purchase option or similar feature that obligates American to absorb decreases in value or entitles American to participate in increases in the value of the aircraft. American does not provide residual value guarantees to the bondholders or equity participants in the trusts and American’s existing leasing arrangements do not contain fixed-price purchase options or similar features. Therefore, American accounts for its EETC leveraged lease financings as operating leases. American’s total future obligations under these leveraged lease financings are $269 million as of December 31, 2014, which are included in the future minimum lease payments table above.
	Special Facility Revenue Bonds
	American guarantees the payment of principal and interest of certain special facility revenue bonds issued by municipalities primarily to build or improve airport facilities and purchase equipment which is leased to American. Under such leases, American is required to make rental payments through 2035, sufficient to pay maturing principal and interest payments on the related bonds. As of December 31, 2014, the remaining lease payments guaranteeing the principal and interest on these bonds are $449 million, which are accounted for as operating leases.
	(f) Legal Proceedings
	Chapter 11 Cases. As previously disclosed, on the Petition Date, November 29, 2011, the Debtors filed the Chapter 11 Cases. On October 21, 2013, the Bankruptcy Court entered the Confirmation Order confirming the Plan. On the Effective Date, December 9, 2013, the Debtors consummated their reorganization pursuant to the Plan, principally through the transactions contemplated by the Merger Agreement pursuant to which Merger Sub merged with and into US Airways Group, with US Airways Group surviving as a wholly-owned subsidiary of AAG. From the Petition Date through the Effective Date, pursuant to automatic stay provisions under the Bankruptcy Code and orders granted by the Bankruptcy Court, actions to enforce or otherwise effect repayment of liabilities preceding the Petition Date as well as all pending litigation against the Debtors generally were stayed. Following the Effective Date, actions to enforce or otherwise effect repayment of liabilities preceding the Petition Date, generally have been permanently enjoined. Any unresolved claims will continue to be subject to the claims reconciliation process under the supervision of the Bankruptcy Court. However, certain pending litigation related to pre-petition liabilities may proceed in courts other than the Bankruptcy Court to determine the amount, if any, of such litigation claims for purposes of treatment under the Plan.
	Pursuant to rulings of the Bankruptcy Court, the Plan established the Disputed Claims Reserve to hold shares of AAG Common Stock reserved for issuance to disputed claimholders at the Effective Date that ultimately become holders of allowed Single-Dip Unsecured Claims. The shares provided for under the Plan were determined based upon a Disputed Claims Reserve amount of claims of approximately $755 million, representing the maximum amount of additional distributions to subsequently allowed Single-Dip Unsecured Claims under the Plan. On July 1, 2014 (the date 180 days after the Effective Date), approximately 2.9 million shares of AAG Common Stock held in the Disputed Claims Reserve were distributed to holders of allowed Single-Dip Unsecured Claims, to holders of certain labor-related deemed claims, and to holders of certain non-management, non-union employee deemed claims as specified in the Plan, and shares were withheld or sold on account of related tax obligations. In addition, on July 1, 2014, American repurchased 0.4 million shares of AAG Common Stock for an aggregate of $19 million from the Disputed Claims Reserve at the then prevailing market price in order to fund cash tax obligations resulting from distributions by the Disputed Claims Reserve. On November 4, 2014, approximately 0.7 million shares of AAG Common Stock held in the Disputed Claims Reserve were distributed to holders of allowed Single-Dip Unsecured Claims, to holders of certain labor-related deemed claims, and to holders of certain non-management, non-union employee deemed claims as specified in the Plan, and shares were withheld or sold on account of related tax obligations. In addition, on November 4, 2014, American repurchased less than 0.1 million shares of AAG Common Stock for an aggregate of $2 million from the Disputed Claims Reserve at the then prevailing market price in order to fund cash tax obligations resulting from distributions by the Disputed Claims Reserve. As of December 31, 2014, there were approximately 26.8 million shares of AAG Common Stock remaining in the Disputed Claims Reserve. On February 10, 2015, approximately 0.8 million shares of AAG Common Stock held in the Disputed Claims Reserve were distributed to holders of allowed Single-Dip Unsecured Claims, to holders of certain labor-related deemed claims, and to holders of certain non-management, non-union employee deemed claims as specified in the Plan, and shares were withheld or sold on account of related tax obligations. In addition, on February 10, 2015, American repurchased less than 0.1 million shares of AAG Common Stock for an aggregate of $4 million from the Disputed Claims Reserve at the then prevailing market price in order to fund cash tax obligations resulting from distributions by the Disputed Claims Reserve. As disputed claims are resolved, the claimants will receive distributions of shares from the Disputed Claims Reserve on the same basis as if such distributions had been made on or about the Effective Date. However, American is not required to distribute additional shares above the limits contemplated by the Plan, even if the shares remaining for distribution are not sufficient to fully pay any additional allowed unsecured claims. To the extent that any of the reserved shares remain undistributed upon resolution of all remaining disputed claims, such shares will not be returned to AAG but rather will be distributed to former AMR shareholders as of the Effective Date. However, resolution of disputed claims could have a material effect on recoveries by holders of additional allowed Single-Dip Unsecured Claims under the Plan and the amount of additional share distributions, if any, that are made to former AMR shareholders as the total number of shares of AAG Common Stock that remain available for distribution upon resolution of disputed claims is limited pursuant to the Plan.
	There is also pending in the Bankruptcy Court an adversary proceeding relating to an action brought by American to seek a determination that certain non-pension, post-employee benefits (OPEB) are not vested benefits and thus may be modified or terminated without liability to American. On April 18, 2014, the Bankruptcy Court granted American’s motion for summary judgment with respect to certain non-union employees, concluding that their benefits were not vested and could be terminated. The summary judgment motion was denied with respect to all other retirees. The Bankruptcy Court has not yet scheduled a trial on the merits concerning whether those retirees’ benefits are vested, and American cannot predict whether it will receive relief from obligations to provide benefits to any of those retirees. American’s financial statements presently reflect these retirement programs without giving effect to any modification or termination of benefits that may ultimately be implemented based upon the outcome of this proceeding. Separately, both the Association of Professional Flight Attendants and Transport Workers Union have filed grievances asserting that American was “successful” in its Chapter 11 with respect to matters related to OPEB and, accordingly, by operation of the underlying collective bargaining agreements, American’s prior contributions to certain OPEB prefunding trusts attributable to active employees should be returned to those active employees. These amounts aggregate approximately $212 million. American has denied both grievances and intends to defend these matters vigorously.
	Private Party Antitrust Action. On July 2, 2013, a lawsuit captioned Carolyn Fjord, et al., v. US Airways Group, Inc., et al., was filed in the United States District Court for the Northern District of California. The complaint names as defendants US Airways Group and US Airways, and alleges that the effect of the Merger may be to substantially lessen competition or tend to create a monopoly in violation of Section 7 of the Clayton Antitrust Act. The relief sought in the complaint includes an injunction against the Merger, or divestiture. On August 6, 2013, the plaintiffs re-filed their complaint in the Bankruptcy Court, adding AMR and American as defendants, and on October 2, 2013, dismissed the initial California action. The Bankruptcy Court denied plaintiffs’ motion to preliminarily enjoin the Merger. On January 10, 2014, the plaintiffs moved to amend their complaint to add additional factual allegations, a claim for money damages and a request for preliminary injunctive relief requiring the carriers to hold separate their assets. On March 14, 2014, the Court allowed plaintiffs to add certain allegations but denied plaintiffs’ requests to add a damages claim or seek preliminary injunctive relief requiring the carriers to hold separate their assets. On June 2, 2014, plaintiffs filed an amended motion for leave to file a second amended and supplemental complaint, which motion has been fully briefed by the parties and is pending resolution by the Court. There is currently no trial date set. American believes this lawsuit is without merit and intends to vigorously defend against the allegations.
	General. American is also engaged in other legal proceedings from time to time. Legal proceedings can be complex and take many months, or even years, to reach resolution, with the final outcome depending on a number of variables, some of which are not within the control of American. Therefore, although American will vigorously defend itself in each of the actions described above and such other legal proceedings, their ultimate resolution and potential financial and other impacts on American are uncertain.
	(g) Guarantees and Indemnifications
	American is a party to many routine contracts in which it provides general indemnities in the normal course of business to third parties for various risks. American is not able to estimate the potential amount of any liability resulting from the indemnities. These indemnities are discussed in the following paragraphs.
	In its aircraft financing agreements, American generally indemnifies the financing parties, trustees acting on their behalf and other relevant parties against liabilities (including certain taxes) resulting from the financing, manufacture, design, ownership, operation and maintenance of the aircraft regardless of whether these liabilities (or taxes) relate to the negligence of the indemnified parties.
	American’s loan agreements and other London Interbank Offered Rate (LIBOR)-based financing transactions (including certain leveraged aircraft leases) generally obligate American to reimburse the applicable lender for incremental costs due to a change in law that imposes (i) any reserve or special deposit requirement against assets of, deposits with or credit extended by such lender related to the loan, (ii) any tax, duty or other charge with respect to the loan (except standard income tax) or (iii) capital adequacy requirements. In addition, American’s loan agreements, derivative contracts and other financing arrangements typically contain a withholding tax provision that requires American to pay additional amounts to the applicable lender or other financing party, generally if withholding taxes are imposed on such lender or other financing party as a result of a change in the applicable tax law.
	These increased cost and withholding tax provisions continue for the entire term of the applicable transaction, and there is no limitation on the maximum additional amounts American could be obligated to pay under such provisions. Any failure to pay amounts due under such provisions generally would trigger an event of default and, in a secured financing transaction, would entitle the lender to foreclose on the collateral to realize the amount due.
In certain transactions, including certain aircraft financing leases and loans, the lessors, lenders and/or other parties have rights to terminate the transaction based on changes in foreign tax law, illegality or certain other events or circumstances. In such a case, American may be required to make a lump sum payment to terminate the relevant transaction.
American has general indemnity clauses in many of its airport and other real estate leases where American as lessee indemnifies the lessor (and related parties) against liabilities related to American’s use of the leased property. Generally, these indemnifications cover liabilities resulting from the negligence of the indemnified parties, but not liabilities resulting from the gross negligence or willful misconduct of the indemnified parties. In addition, American provides environmental indemnities in many of these leases for contamination related to American’s use of the leased property.
Under certain contracts with third parties, American indemnifies the third-party against legal liability arising out of an action by the third-party, or certain other parties. The terms of these contracts vary and the potential exposure under these indemnities cannot be determined. American has liability insurance protecting American for some of the obligations it has undertaken under these indemnities.
American is involved in certain claims and litigation related to its operations. American is also subject to regulatory assessments in the ordinary course of business. American establishes reserves for litigation and regulatory matters when those matters present loss contingencies that are both probable and can be reasonably estimated. In the opinion of management, liabilities, if any, arising from these regulatory matters, claims and litigation will not have a material adverse effect on American’s consolidated financial position, results of operations, or cash flows, after consideration of available insurance.
In connection with the Merger and pursuant to the Plan on December 9, 2013, AAG and American entered into a joinder to the loan agreement and became co-obligors of US Airways Group’s $1.6 billion 2013 Citicorp Credit Facility and AAG and American entered into a second supplemental indenture that guarantees the payment obligations associated with the 6.125% senior notes.
(h) Other
In 2010, American and Japan Airlines entered into a JBA under which, amongst other things, American provided Japan Airlines a guarantee of certain minimum incremental revenue resulting from the successful operation of the joint business for the first three years following its implementation, subject to certain terms and conditions. The amount required to be paid by American under the guarantee in any one of such years may not exceed $100 million, and is reduced if capacity for one of such years is less than a defined base year period capacity. As of December 31, 2013, American reached an agreement with Japan Airlines to settle the liability for $90 million. The liability is expected to be settled in 2015.
In the fourth quarter of 2012, American entered into a settlement agreement resolving a commercial dispute. The settlement agreement includes two elements which were valued at relative fair value and will be recognized when earned. American determined that the settlement includes a litigation gain of $280 million, which was valued using future cash flows and recognized in the fourth quarter of 2012. The settlement also includes an incentive which is contingent upon signing a future contract and will be recognized over the term of the future contract. The contract was signed in January 2014. In connection with the new contract, American recorded an additional $70 million receivable with an offset to other liabilities to be recognized over the course of the remaining contract term.
As a result of the terrorist attacks of September 11, 2001 (the Terrorist Attacks) and the subsequent liability protections provided for by the Air Transportation Safety and System Stabilization Act (the Stabilization Act), American recorded a liability for the Terrorist Attacks claims equal to the related insurance receivable due to American. The Stabilization Act provides that, notwithstanding any other provision of law, liability for all claims, whether compensatory or punitive, arising from the Terrorist Attacks, against any air carrier shall not exceed the liability coverage maintained by the air carrier. As of December 31, 2014, the remaining liability and the amount of the offsetting receivable were each $974 million.

	The Company is managed as a single business unit that provides air transportation for passengers and cargo. This allows it to benefit from an integrated revenue pricing and route network that includes American, US Airways, Envoy, Piedmont, PSA and third-party carriers that fly under capacity purchase or prorate agreements as part of the Company’s regional operations. The flight equipment of all these carriers is combined to form one fleet that is deployed through a single route scheduling system. When making resource allocation decisions, the chief operating decision maker evaluates flight profitability data, which considers aircraft type and route economics, but gives no weight to the financial impact of the resource allocation decision on an individual carrier basis. The objective in making resource allocation decisions is to maximize consolidated financial results, not the individual results of American, US Airways, Envoy, Piedmont and PSA.

Share-based Compensation	12 Months Ended

Share-based Compensation	18.  Share-based Compensation
	In December 2013, the Board of Directors of AAG approved the 2013 AAG Incentive Award Plan (the 2013 Plan). Awards may be in the form of an option, restricted stock award, restricted stock unit award, performance award, dividend equivalent award, deferred stock award, deferred stock unit award, stock payment award or stock appreciation right. The 2013 Plan authorizes the grant of awards for the issuance of 40 million shares plus any shares underlying awards granted under the 2013 Plan, or any pre-existing US Airways Group plan, that are forfeited, terminate or are cash settled (in whole or in part) without a payment being made in the form of shares. In addition, any shares that are available for issuance under the US Airways Group 2011 Incentive Award Plan (the 2011 Plan) as of the effective date of the Merger may be used for awards under the 2013 Plan; provided, that awards using such available shares under the 2011 Plan shall not be made after the date awards or grants could have been made under the 2011 Plan and shall only be made to individuals who were not providing services to AAG prior to the Merger. Awards granted under the 2013 Plan upon the assumption of, or in substitution for, outstanding awards in connection with a corporate transaction, such as a merger, will not reduce the shares authorized for issuance under the 2013 Plan.
	In addition, pursuant to the Plan, and as approved by the Bankruptcy Court, certain officers, directors and employees received share-based incentive awards related to the Merger and future service. Awards issued in conjunction with the Plan are discussed in more detail below.
	All outstanding US Airways Group equity awards were converted into equity awards with respect to AAG Common Stock using an exchange ratio of 1 to 1 and had a fair value of approximately $141 million at the Merger, which was included in the purchase price. These awards have the same terms and conditions as were applicable to such equity awards immediately prior to the Merger closing date.
	The Company’s net income for the years ended December 31, 2014, 2013 and 2012 included $381 million, $92 million and $29 million respectively, of share-based compensation costs. Of the 2014 and 2013 amounts, $224 million and $42 million, respectively, were related to the Merger and recorded in special items, net on the accompanying consolidated statements of operations.
	(a) Restricted Stock Unit (RSU) Awards
	As of December 31, 2014, the Company has outstanding restricted stock unit awards with service conditions (time vested) and performance conditions. The grant-date fair value of restricted stock unit awards is equal to the market price of the underlying shares of common stock on the date of grant. For time vested awards, the expense is recognized on a straight-line basis over the vesting period for the entire award. For awards with performance conditions, the expense is recognized based on the expected achievement at each reporting period. Stock-settled restricted stock unit awards (RSUs) are classified as equity awards as the vesting results in the issuance of shares of AAG Common Stock. Cash-settled restricted stock unit awards (CRSUs) are classified as liability awards as the vesting results in payment of cash by the Company. The Company granted certain RSU awards in connection with the Merger as follows:
	Alignment Awards
	On December 9, 2013, alignment awards were granted in the form of RSUs. The awards were provided to legacy AMR employees in order to align interests and create parity with peers at US Airways Group, and one-third of the awards vested on the Company’s emergence from bankruptcy. The remaining awards vest equally on the one and two year anniversary of emergence. Employees terminated in connection with the Merger fully vest in their awards on the termination date. Compensation expenses for these awards are recorded in special items, net on the consolidated statements of operations.
	Merger Equity Grant
	The Merger Equity Grant was granted on the Effective Date to certain officers and directors and employees in the form of RSUs and will be settled in equity for domestic employees and in cash for international employees. Each restricted stock unit award granted will vest, subject to the executive’s continued employment, with respect to (i) 50% of the restricted stock units on December 16, 2015; (ii) 25% of the restricted stock units on the earlier to occur of (a) December 16, 2015, if the Company is issued a Single Operating Certificate prior to or on that date or (b) the date on which the Company is issued a Single Operating Certificate, provided that such date is prior to or on December 9, 2016; and (iii) 25% of the restricted stock units on the date the Board of Directors or compensation committee of the Board of Directors determines that the Company has achieved at least $1.0 billion in net synergies with respect to fiscal year 2015 or 2016. Compensation expenses for these awards are recorded in special items, net on the consolidated statements of operations.

Stock options and stock appreciation rights have service conditions, become exercisable over a three-year vesting period and expire if unexercised at the end of their term, which ranges from seven to ten years. Stock options and stock-settled stock appreciation rights (SARs) are classified as equity awards as the exercise results in the issuance of shares of AAG Common Stock.

Awards may be in the form of an option, restricted stock award, restricted stock unit award, performance award, dividend equivalent award, deferred stock award, deferred stock unit award, stock payment award or stock appreciation right. The 2013 Plan authorizes the grant of awards for the issuance of 40 million shares plus any shares underlying awards granted under the 2013 Plan, or any pre-existing US Airways Group plan, that are forfeited, terminate or are cash settled (in whole or in part) without a payment being made in the form of shares. In addition, any shares that are available for issuance under the US Airways Group 2011 Incentive Award Plan (the 2011 Plan) as of the effective date of the Merger may be used for awards under the 2013 Plan; provided, that awards using such available shares under the 2011 Plan shall not be made after the date awards or grants could have been made under the 2011 Plan and shall only be made to individuals who were not providing services to AAG prior to the Merger. Awards granted under the 2013 Plan upon the assumption of, or in substitution for, outstanding awards in connection with a corporate transaction, such as a merger, will not reduce the shares authorized for issuance under the 2013 Plan.
	In addition, pursuant to the Plan, and as approved by the Bankruptcy Court, certain officers, directors and employees received share-based incentive awards related to the Merger and future service. Awards issued in conjunction with the Plan are discussed in more detail below.
	All outstanding US Airways Group equity awards were converted into equity awards with respect to AAG Common Stock using an exchange ratio of 1 to 1 and had a fair value of approximately $141 million at the Merger, which was included in the purchase price. These awards have the same terms and conditions as were applicable to such equity awards immediately prior to the Merger closing date.
	AAG’s net income for the years ended December 31, 2014 and 2013 included $381 million and $92 million, respectively, of share-based compensation costs.

	-1	The Company’s weighted average diluted shares outstanding for the 2013 quarters presented include the weighted effect of shares outstanding for both the pre and post-merger periods. The shares outstanding for the pre-merger periods (January 1, 2013 through December 8, 2013) consist only of the AMR common stock formerly traded under the symbol: “AAMRQ”. In accordance with GAAP, these former AAMRQ shares have been adjusted for all periods presented to retrospectively reflect the distributions made to date pursuant to the Company’s Plan, whereby holders of AAMRQ have received 0.7441 shares of AAG Common Stock per share of AAMRQ. The shares outstanding for the 23 day post-merger period (December 9, 2013 through December 31, 2013) include the full amount of shares to be issued pursuant to the Plan over the 120 day distribution period adjusted for approximately 13 million shares withheld by the Company in satisfaction of employee tax obligations.
	Former holders of AAMRQ shares as of the Effective Date may in the future receive additional distributions of AAG Common Stock dependent upon the ultimate distribution of shares of AAG Common Stock to holders of disputed claims. Thus, the shares and related earnings per share calculation prior to the Effective Date may change in the future to reflect additional retrospective adjustments for future AAG Common Stock distributions to former holders of AAMRQ shares.
	The Company’s fourth quarter 2014 results reflect $507 million of net special items consisting of $280 million of merger integration expenses related to information technology, alignment of labor union contracts, professional fees, severance and retention, share-based compensation, divestiture of London Heathrow Slots, fleet restructuring, re-branding of aircraft and airport facilities, relocation and training. In addition, the Company recorded a net $116 million charge for bankruptcy related items principally consisting of fair value adjustments for bankruptcy settlement obligations, a $70 million charge related primarily to certain spare parts asset impairments as well as a $24 million charge due to a new pilot labor contract at the Company’s Envoy regional subsidiary. The Company also recorded a $31 million nonoperating special charge principally for Venezuelan foreign currency losses. These charges were offset in part by an $8 million gain on the sale of certain spare parts as well as a $6 million non-cash deferred income tax benefit related to certain indefinite-lived intangible assets.
	The Company’s fourth quarter 2013 results reflect $2.4 billion of net special items consisting of $2.2 billion of reorganization items principally due to a $1.7 billion deemed claim to employees pursuant to the Plan as well as professional fees and estimated allowed claim amounts, $393 million of Merger related expenses due to the alignment of labor union contracts, professional fees, severance, share-based compensation and fees for US Airways to exit the Star Alliance and its codeshare agreement with United Airlines, a $214 million tax charge attributable to additional valuation allowance required to reduce deferred tax assets to the amount more likely than not to be realized, a $107 million charge related to American’s pilot long-term disability obligation, a $33 million aircraft impairment charge and $20 million of interest charges to recognize post-petition interest expense on unsecured obligations pursuant to the Plan. These charges were offset in part by a $538 million non-cash income tax benefit resulting from gains recorded in OCI, a $67 million gain on the sale of Slots at LaGuardia Airport and a $31 million credit to other revenue related to a change in accounting method resulting from the modification of the Company’s AAdvantage miles agreement with Citibank.

Financial Information for Subsidiary Guarantors and Non-guarantor Subsidiaries	21.  Financial Information for Subsidiary Guarantors and Non-guarantor Subsidiaries
	There are various cross-guarantees among the Company, American, US Airways Group and US Airways with respect to publicly held debt securities. In connection with the Merger, the Company and American entered into a second supplemental indenture under which they jointly and severally guaranteed the payment obligations of US Airways Group under the 6.125% senior notes. In addition, on March 31, 2014, the Company, US Airways Group and US Airways entered into amended and restated guarantees of the payment obligations of US Airways under the equipment notes relating to each of its Series 2010-1, 2011-1, 2012-1, 2012-2 and 2013-1 Pass Through Certificates, the result of which was to add AAG as a guarantor of such equipment notes on a joint and several basis with US Airways Group. In September 2014, the Company issued $750 million aggregate principal amount of the 5.50% senior notes, which are fully and unconditionally guaranteed by American, US Airways Group and US Airways.
	In connection with the issuance of these guarantees, in accordance with Rule 3-10 of Regulation S-X and Rule 12h-5 under the Securities Exchange Act of 1934, as amended, US Airways Group and US Airways discontinued filing separate periodic and current reports with the SEC. As a result, in accordance with Rule 3-10, the Company is providing the following consolidating financial information for American Airlines Group (Parent Company Only), American, US Airways Group (Parent Company Only), US Airways and all other non-guarantor subsidiaries, together with the consolidating adjustments necessary to present the Company’s results on a consolidated basis. For the financial statements of US Airways Group and US Airways for the fiscal year ended December 31, 2013, please refer to the Annual Report on Form 10-K of each such company filed with the SEC on February 28, 2014.

Shares repurchased under the program may be made through a variety of methods, which may include open market purchases, privately negotiated transactions, block trades or accelerated share repurchase transactions. Any such repurchases will be made from time to time subject to market and economic conditions, applicable legal requirements and other relevant factors. The share repurchase program does not obligate the Company to repurchase any specific number of shares and may be suspended at any time at management’s discretion.
	Also on January 27, 2015, the Company announced that its Board of Directors had declared a $0.10 per share dividend for shareholders of record on February 9, 2015, and payable on February 23, 2015.

	AAdvantage Loan
	American had the right to repay in cash, without premium or penalty, any or all of the amounts owed to Citibank under the AAdvantage Loan. Effective January 2, 2015, American exercised its loan repayment right with respect to the full value of the outstanding balance to Citibank for $400 million. In connection with the repayment, in the first quarter of 2015, American will recognize an early debt extinguishment gain of approximately $17 million. The entire outstanding balance of the obligation is reflected in current maturities of long-term debt on the accompanying consolidated balance sheet as of December 31, 2014.
	Distribution of AAG Common Stock
	On February 10, 2015, approximately 0.8 million shares of AAG Common Stock held in the Disputed Claims Reserve were distributed to holders of allowed Single-Dip Unsecured Claims, to holders of certain labor-related deemed claims and to holders of certain non-management, non-union employee deemed claims as specified in the Plan, and shares were withheld or sold on account of related tax obligations.

American Airlines, Inc. [Member]
Bankruptcy Settlement Obligations	3.  Bankruptcy Settlement Obligations
	As of December 31, 2014 and 2013, the components of bankruptcy settlement obligations on American’s consolidated balance sheets are as follows (in millions):
		December 31,
		2014		2013
	Single-Dip and Double-Dip Equity Obligations	$	248	$	4,575
	Labor-related deemed claim		77		849
	Total	$	325	$	5,424
	The AAG Series A Preferred Stock, while outstanding, voted and participated in accordance with the terms of the underlying Certificate of Designation. One quarter of the shares of AAG Series A Preferred Stock initially issued was mandatorily convertible on each of the 30th, 60th, 90th and 120th days after the Effective Date, subject to additional voluntary conversions. The initial stated value of each share of AAG Series A Preferred Stock was $25.00 and accrued dividends at 6.25% per annum, calculated daily, while outstanding. Additionally, AAG Series A Preferred Stock converted to AAG Common Stock based upon the volume weighted average price of the shares of AAG Common Stock on the five trading days immediately preceding the conversion date, at a 3.5% fixed discount, subject to a conversion price floor of $10.875 per share and a conversion price cap of $33.8080 per share, below or above which the conversion rate remains fixed. As of April 8, 2014, all shares of AAG Series A Preferred Stock had been converted into AAG Common Stock.
	The Single-Dip Equity Obligations, while outstanding, do not vote or participate in accordance with the terms of the Plan. These equity obligations, representing the amount of total Single-Dip Unsecured Claims not satisfied through the issuance of AAG Series A Preferred Stock at the Effective Date, represented an unconditional obligation to transfer a variable number of shares of AAG Common Stock based predominantly on a fixed monetary amount known at inception, and, as such, were not treated as equity, but rather as liabilities, until the 120th day after emergence, which was April 8, 2014. As of April 8, 2014, AAG has issued shares of AAG Common Stock to satisfy the obligation amount at emergence, plus accrued dividends of 12% per annum, calculated daily, through such date, based on the volume weighted average price of the shares of AAG Common Stock, at a 3.5% discount, as specified in the Plan. The amount of the remaining Single-Dip Equity Obligations at December 31, 2014 is American’s estimate of its obligation for disputed claims of $248 million and is calculated based on the fair value of the shares expected to be issued, measured as if the obligations were settled using the closing price of AAG Common Stock at December 31, 2014. Additional allowed claims will receive 30.7553 shares, subject to reduction for expenses of the Disputed Claims Reserve, including tax liabilities, for each $1,000 of allowed claims. For accounting purposes, the value of the shares expected to be issued is marked-to-market each period until issued. Accordingly, changes in the value of AAG Common Stock could result in future increases and decreases in this obligation.
	In exchange for employees’ contributions to the successful reorganization of AAG, including agreeing to reductions in pay and benefits, AAG and American agreed in the Plan to provide each employee group a deemed claim which was used to provide a distribution of a portion of the equity of the reorganized entity to those employees. Each employee group received a deemed claim amount based upon a fixed percentage of the distributions to be made to general unsecured claimholders. The fair value based on the expected number of shares to be distributed to satisfy this deemed claim, as adjusted, was approximately $1.5 billion. From the Effective Date through December 31, 2014, AAG has made distributions of $988 million in AAG Common Stock and paid approximately $553 million in cash to cover payroll and other taxes related to the equity distributions. As of December 31, 2014, the liability to certain AMR labor groups and employees of $77 million represents the estimated fair value of the remaining shares expected to be issued in satisfaction of such obligation, measured as if the obligation were settled using the closing price of AAG Common Stock at December 31, 2014. For accounting purposes, the value of the remaining shares expected to be issued to satisfy the labor claim is marked-to-market each period until issued. Accordingly, changes in the value of AAG Common Stock could result in future increases and decreases in this obligation.
	On July 1, 2014, approximately 2.9 million shares of AAG Common Stock held in the Disputed Claims Reserve were distributed to holders of allowed Single-Dip Unsecured Claims, to holders of certain labor-related deemed claims and to holders of certain non-management, non-union employee deemed claims as specified in the Plan, and shares were withheld or sold on account of related tax obligations. In addition, on November 4, 2014, approximately 0.7 million shares of AAG Common Stock held in the Disputed Claims Reserve were distributed to holders of allowed Single-Dip Unsecured Claims, to holders of certain labor-related deemed claims and to holders of certain non-management, non-union employee deemed claims as specified in the Plan, and shares were withheld or sold on account of related tax obligations.
	On February 10, 2015, approximately 0.8 million shares of AAG Common Stock held in the Disputed Claims Reserve were distributed to holders of allowed Single-Dip Unsecured Claims, to holders of certain labor-related deemed claims and to holders of certain non-management, non-union employee deemed claims as specified in the Plan, and shares were withheld or sold on account of related tax obligations.

	Pursuant to a capacity purchase agreement between American and Envoy, American recognizes passenger revenue from flights operated by Envoy and American purchases all of the capacity from Envoy. The capacity purchase agreement reflects what American believes are current market rates received by third-party regional carriers for similar flying. In 2014, 2013 and 2012, American recognized expense of approximately $894 million, $1.0 billion and $1.1 billion, respectively, related to the Envoy capacity purchase agreement.

Basis_of_Presentation_and_Summ1

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Basis of Presentation	(a) Basis of Presentation
	The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. As a result of the Merger, the consolidated financial statements presented include the results of AMR and its wholly-owned subsidiaries, American and Envoy, for periods ended prior to December 9, 2013 and consolidated results of AAG, which includes American, Envoy and US Airways Group, for periods ending on or after December 9, 2013. Accordingly, the consolidated financial statement for the year ended December 31, 2013 includes the accounts of US Airways Group for the 23 days ended December 31, 2013. All significant intercompany transactions have been eliminated.
	The preparation of financial statements in accordance with accounting principles generally accepted in the United States (GAAP) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The most significant areas of judgment relate to passenger revenue recognition, impairment of goodwill, impairment of long-lived and intangible assets, the frequent traveler programs, pensions and retiree medical and other benefits and the deferred tax asset valuation allowance.
Chapter 11 Matters	(b) Chapter 11 Matters
	In accordance with GAAP, the Debtors (as defined in Note 2 above) applied ASC 852 “Reorganizations” (ASC 852) in preparing the consolidated financial statements for periods subsequent to the Chapter 11 Cases (as defined in Note 2 above). ASC 852 requires that the financial statements distinguish transactions and events that are directly associated with the reorganization from the ongoing operations of the business. Accordingly, certain revenues, expenses (including professional fees), realized gains and losses and provisions for losses that are realized or incurred in the Chapter 11 Cases for the 2013 and 2012 period are presented in reorganization items, net on the accompanying consolidated statements of operations.
Restricted Cash and Short-term Investments	(c) Restricted Cash and Short-term Investments
	The Company has restricted cash and short-term investments related primarily to collateral held to support projected workers’ compensation obligations and funds held for certain tax obligations.
Aircraft Fuel, Spare Parts, and Supplies, Net	(d) Aircraft Fuel, Spare Parts, and Supplies, Net
	Aircraft fuel, spare parts, and supplies, net are recorded at net realizable value based on average costs. These items are expensed when used. An allowance for obsolescence is provided for aircraft spare parts and supplies.
Operating Property and Equipment	(e) Operating Property and Equipment
	Operating property and equipment are recorded at cost. Interest expense related to the acquisition of certain property and equipment, including aircraft purchase deposits, is capitalized as an additional cost of the asset. Interest capitalized for the years ended December 31, 2014, 2013 and 2012 was $61 million, $47 million and $50 million, respectively. Property and equipment is depreciated and amortized to residual values over the estimated useful lives or the lease term, whichever is less, using the straight-line method. Costs of major improvements that enhance the usefulness of the asset are capitalized and depreciated over the estimated useful life of the asset or the modifications, whichever is less. The depreciable lives used for the principal depreciable asset classifications are:
	Principal Depreciable Asset Classification		Depreciable Life
	Jet aircraft and engines		16 - 30 years
	Other regional aircraft and engines		25 years
	Major rotable parts, avionics and assemblies		Fleet end date
	Improvements to leased flight equipment		Lesser of asset/leasehold improvement or lease end date
	Buildings and improvements		Lesser of 5 - 30 years or lease term
	Furniture, fixtures and other equipment		3 - 10 years: ranges from computer hardware to furniture
	Capitalized software		Lesser of 5 years or lease term
	Residual values for aircraft, engines, major rotable parts, avionics and assemblies are generally 5% to 10%.
	Equipment and property under capital leases are amortized over the term of the leases or, in the case of certain aircraft, over their expected useful lives. Lease terms vary but are generally 16 to 30 years for aircraft and three to 30 years for other leased equipment and property.
	The Company records impairment charges on long-lived assets used in operations when events and circumstances indicate that the assets may be impaired. An asset or group of assets is considered impaired when the undiscounted cash flows estimated to be generated by the asset are less than the carrying amount of the asset and the net book value of the asset exceeds its estimated fair value. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less cost to sell.
Income Taxes	(f) Income Taxes
	Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. A valuation allowance is established, if necessary, for the amount of any tax benefits that, based on available evidence, are not expected to be realized.
Goodwill	(g) Goodwill
	Goodwill represents the excess of the purchase price over the fair value of the net assets acquired and liabilities assumed. Goodwill is not amortized but tested for impairment annually or more frequently if events or circumstances indicate. The Company has one consolidated reporting unit.
	Goodwill is measured for impairment by initially performing a qualitative screen and, if necessary, then comparing the fair value of the reporting unit to its carrying value, including goodwill. If the fair value of the reporting unit is less than the carrying value, a second step is performed to determine the implied fair value of goodwill. If the implied fair value of goodwill is lower than its carrying value, an impairment charge equal to the difference is recorded. Based upon the Company’s annual testing, there was no goodwill impairment in 2014.
Other Intangibles, Net	(h) Other Intangibles, Net
	Intangible assets consist primarily of airport take-off and landing rights (Slots), customer relationships, marketing agreements, international Slots and route authorities, gate leasehold rights and tradenames. Intangible assets with estimable useful lives are amortized over their respective estimated useful lives to their estimated residual values and reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable.
	The following table provides information relating to the Company’s amortizable intangible assets as of December 31, 2014 and 2013 (in millions):
			December 31,
			2014			2013
	Airport Slots		$	365		$	332
	Customer relationships			300			300
	Marketing agreements			105			105
	Tradenames			35			35
	Airport gate leasehold rights			138			155
	Accumulated amortization			(447	)		(373	)
	Total		$	496		$	554
	Airport operating and gate lease rights are being amortized on a straight-line basis over 25 years to a zero residual value. The customer relationships, marketing agreements and tradenames were identified as intangible assets subject to amortization and are amortized on a straight-line basis over approximately nine years, 30 years and 15 months, respectively.
	The Company recorded amortization expense related to these intangible assets of approximately $81 million, $20 million and $25 million for the years ended December 31, 2014, 2013 and 2012, respectively. The Company expects to record annual amortization expense for the aforementioned definite-life intangible assets as follows (in millions):
	2015		$	56
	2016			50
	2017			46
	2018			42
	2019			42
	2020 and thereafter			260
	Total		$	496
	The Company’s indefinite-lived assets include certain international Slots and route authorities and domestic airport take-off and landing slots. Indefinite-lived assets are not amortized but instead are reviewed for impairment annually and more frequently if events or circumstances indicate that the asset may be impaired. As of December 31, 2014 and 2013, the Company had $1.7 billion and $1.8 billion, respectively, of indefinite-lived intangible assets on its consolidated balance sheets.
	The Company’s indefinite-lived intangible assets are reviewed for impairment by initially performing a qualitative screen to determine whether the Company believes it is more likely than not that an asset has been impaired. If the Company believes an impairment has occurred, the Company then evaluates for impairment by comparing the estimated fair value of assets to the carrying value. An impairment charge is recognized if the asset’s estimated fair value is less than its carrying value. Based upon the Company’s annual testing, there was no indefinite-lived intangible asset impairment in 2014.
Frequent Flyer Programs	(i) Frequent Flyer Programs
	AAG currently operates two frequent traveler programs, American’s AAdvantage and US Airways’ Dividend Miles. These programs award mileage credits to passengers who fly on American, US Airways and oneworld carriers, as well as certain other partner airlines that participate in the programs. Mileage credits can also be earned through purchases from other non-airline partners that participate in the Company’s respective loyalty programs. Mileage credits can be redeemed for travel on American, US Airways or other participating partner airlines, in which case the Company pays a fee.
	The Company uses the incremental cost method to account for the portion of the Company’s frequent flyer liability incurred when AAdvantage and Dividend Miles members earn mileage credits by flying on American, US Airways or its regional affiliates. The Company has an obligation to provide future travel when these mileage credits are redeemed and therefore has recorded a liability for mileage credits outstanding.
	The incremental cost liability includes all mileage credits that are expected to be redeemed, including mileage credits earned by members whose mileage account balances have not yet reached the minimum mileage credit level required to redeem an award. Additionally, outstanding mileage credits are subject to expiration if unused. In calculating the liability, the Company estimates how many mileage credits will never be redeemed for travel and excludes those mileage credits from the estimate of the liability. Estimates are also made for the number of miles that will be used per award redemption and the number of travel awards that will be redeemed on partner airlines. These estimates are based on historical program experience as well as consideration of enacted program changes, as applicable. Changes in the liability resulting from members earning additional mileage credits or changes in estimates are recorded in the statement of operations as a part of passenger revenue.
	The liability for outstanding mileage credits is valued based on the estimated incremental cost of carrying one additional passenger. Incremental cost primarily includes unit costs incurred for fuel, food, and insurance as well as fees incurred when travel awards are redeemed on partner airlines. No profit or overhead margin is included in the accrual of incremental cost. These estimates are generally updated based upon the Company’s 12-month historical average of such costs.
	The Company applied the acquisition method of accounting in connection with the Merger and therefore recorded the liability for outstanding US Airways mileage credits at fair value. As of December 31, 2014 and 2013, the liability for outstanding mileage credits expected to be redeemed for future travel awards for US Airways under the Dividend Miles program was $638 million and $932 million and is included on the consolidated balance sheets within frequent flyer liability. This liability will be reduced as miles are redeemed and new miles earned will be recorded as a liability based on the incremental cost method discussed above.
	As of December 31, 2014 and 2013 the liability for outstanding mileage credits for the AAdvantage program was $647 million and $580 million, respectively, and is included on the consolidated balance sheets within frequent flyer liability.
	American and US Airways also sell frequent flyer program mileage credits to participating airline partners and non-airline business partners. Sales of mileage credits to business partners is comprised of two components, transportation and marketing. Historically, American and US Airways have used the residual method of accounting to determine the values of each component as there had not been a material modification to any significant agreements since the adoption of Accounting Standards Update (ASU) No. 2009-13, “Revenue Recognition (Topic 605) – Multiple-Deliverable Revenue Arrangements” on January 1, 2011.
	In 2013, American and Citibank amended their AAdvantage co-branded credit card agreement, which resulted in a material modification of the terms of the arrangement. Also, in connection with the acquisition of US Airways on December 9, 2013, a material modification occurred on all of US Airways’ agreements in connection with the Merger. Therefore, subsequent to the amendments of these arrangements, AAG applied the relative selling price method to determine the values of each deliverable. Under the relative selling price approach, American and US Airways identified five revenue elements for the co-branded credit card agreement with Citibank and Dividend Miles co-branded credit card agreement with Barclays: the transportation component; use of the American and US Airways’ brand including access to frequent flyer member lists; advertising; lounge access; and baggage services (together excluding “the transportation component,” the “marketing component”).
	The transportation component represents the estimated selling price of future travel awards and is determined using historical transaction information, including information related to customer redemption patterns. The transportation component is deferred based on its relative selling price and amortized into passenger revenue on a straight-line basis over the period in which the mileage credits are expected to be redeemed for travel.
	The marketing component represents services provided to the Company’s business partners and relates primarily to the use of American’s and US Airways’ logo and tradenames along with access to customers lists of AAdvantage and Dividend Miles members. The marketing services are provided periodically, but no less than monthly. Accordingly, the marketing component is considered earned and recognized in other revenues in the period of the mileage sale.
	Upon application of the relative selling price method in 2013 for American’s Citibank modification, American reduced its travel component liability and recorded other revenue of approximately $31 million. As a result of the change in the marketing component value when the relative selling price method is applied, American and US Airways now defer less revenue per mile sold. For American’s agreements where there has not been a material modification, it continues to apply the residual method.
	As of December 31, 2014 and 2013, the Company had $1.5 billion in deferred revenue from the sale of mileage credits (recorded as frequent flyer liability on the consolidated balance sheets). For the years ended December 31, 2014, 2013 and 2012, the marketing component of mileage sales recognized at the time of sale in other revenues was approximately $1.4 billion, $834 million and $725 million, respectively.
Passenger Revenue	(j) Passenger Revenue
	Passenger ticket sales are initially recorded as a component of air traffic liability. Revenue derived from ticket sales is recognized at the time service is provided. However, due to various factors, including the complex pricing structure and interline agreements throughout the industry, certain amounts are recognized in revenue using estimates regarding both the timing of the revenue recognition and the amount of revenue to be recognized, including breakage. These estimates are generally based upon the evaluation of historical trends, including the use of regression analysis and other methods to model the outcome of future events based on the Company’s historical experience, and are recorded at the scheduled time of departure.
	The Company purchases capacity, or ASMs, generated by the Company’s wholly-owned regional air carriers and the capacity of Air Wisconsin Airlines Corporation (Air Wisconsin), Republic Airways Holdings’ subsidiaries Republic Airlines (Republic) and Chautauqua Airlines (Chautauqua), Mesa Airlines, Inc. (Mesa), and SkyWest Airlines, Inc.’s subsidiaries Sky West Airlines (SkyWest) and ExpressJet Airlines (ExpressJet) in certain markets. The Company’s wholly-owned regional air carriers and Air Wisconsin, Chautauqua, ExpressJet, Republic, Mesa, and SkyWest operate regional aircraft in these markets as part of either American Eagle carriers or US Airways Express. The Company classifies revenues generated from transportation on these carriers as regional passenger revenues. Liabilities related to tickets sold by the Company for travel on these air carriers are also included in the Company’s air traffic liability and are subsequently relieved in the same manner as described above.
	Various taxes and fees assessed on the sale of tickets to end customers are collected by the Company as an agent and remitted to taxing authorities. These taxes and fees have been presented on a net basis in the accompanying consolidated statements of operations and recorded as a liability until remitted to the appropriate taxing authority.
Maintenance, Materials and Repairs	(k) Maintenance, Materials and Repairs
	Maintenance and repair costs for owned and leased flight equipment are charged to operating expense as incurred, except costs incurred for maintenance and repair under flight hour maintenance contract agreements, which are accrued based on contractual terms when an obligation exists.
Selling Expenses	(l) Selling Expenses
	Selling expenses include commissions, credit card fees, computerized reservations systems fees and advertising. Advertising expenses are expensed as incurred. Advertising expense was $100 million, $166 million and $153 million for the years ended December 31, 2014, 2013 and 2012, respectively.
Share-based Compensation	(m) Share-based Compensation
	The Company accounts for its share-based compensation expense based on the fair value of the stock award at the time of grant, which is recognized ratably over the vesting period of the stock award. The fair value of stock options and stock appreciation rights is estimated using a Black-Scholes option pricing model. The fair value of restricted stock units is based on the market price of the underlying shares of common stock on the date of grant. See Note 18 for further discussion of share-based compensation.
Deferred Gains and Credits, Net	(n) Deferred Gains and Credits, Net
	Included within deferred gains and credits, net are amounts deferred and amortized into future periods associated with the adjustment of leases to fair value in connection with the application of acquisition accounting, deferred gains on the sale leaseback of aircraft and certain vendor incentives.
Foreign Currency Gains and Losses	(o) Foreign Currency Gains and Losses
	Foreign currency gains and losses are recorded as part of other nonoperating expense, net in the consolidated statements of operations. Foreign currency losses for 2014, 2013 and 2012 were $114 million, $56 million and $41 million, respectively.
Regional Expenses	(p) Regional Expenses
	Expenses associated with the Company’s wholly-owned regional airlines and third-party regional carriers operating under the brand names American Eagle and US Airways Express are classified as regional expenses on the consolidated statements of operations. Regional expenses consist of the following (in millions):
			Year Ended December 31,
			2014			2013			2012
	Aircraft fuel and related taxes		$	2,009		$	1,120		$	1,012
	Salaries, wages and benefits			1,078			692			681
	Capacity purchases from third-party regional carriers (1)			1,475			269			129
	Maintenance, materials and repairs			367			284			285
	Other rent and landing fees			419			236			222

Recent Accounting Pronouncements	(q) Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09 completes the joint effort by the FASB and International Accounting Standards Board (IASB) to improve financial reporting by creating common revenue recognition guidance for U.S. GAAP and International Financial Reporting Standards (IFRS). ASU 2014-09 applies to all companies that enter into contracts with customers to transfer goods or services. ASU 2014-09 is effective for public entities for interim and annual reporting periods beginning after December 15, 2016. Early application is not permitted and entities have the choice to apply ASU 2014-09 either retrospectively to each reporting period presented or by recognizing the cumulative effect of applying ASU 2014-09 at the date of initial application and not adjusting comparative information. The Company is currently evaluating the requirements of ASU 2014-09 and has not yet determined its impact on the Company’s consolidated financial statements.
American Airlines, Inc. [Member]
Basis of Presentation	(a) Basis of Presentation
	The consolidated financial statements as of and for the years ended December 31, 2014, 2013 and 2012 include the accounts of American. American is a wholly-owned subsidiary of American Airlines Group Inc. (AAG). All significant intercompany transactions have been eliminated.
	The preparation of financial statements in accordance with accounting principles generally accepted in the United States (GAAP) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The most significant areas of judgment relate to passenger revenue recognition, impairment of long-lived and intangible assets, the frequent traveler program, pensions and retiree medical and other benefits and the deferred tax asset valuation allowance.
Chapter 11 Matters	(b) Chapter 11 Matters
	In accordance with GAAP, the Debtors (as defined in Note 2 above) applied ASC 852 “Reorganizations” (ASC 852) in preparing the consolidated financial statements for periods subsequent to the Chapter 11 Cases (as defined in Note 2 above). ASC 852 requires that the financial statements distinguish transactions and events that are directly associated with the reorganization from the ongoing operations of the business. Accordingly, certain revenues, expenses (including professional fees), realized gains and losses and provisions for losses that are realized or incurred in the Chapter 11 Cases for the 2013 and 2012 period are presented in reorganization items, net on the accompanying consolidated statements of operations.
Restricted Cash and Short-term Investments	(c) Restricted Cash and Short-term Investments
	American has restricted cash and short-term investments related primarily to collateral held to support projected workers’ compensation obligations and funds held for certain tax obligations.
Aircraft Fuel, Spare Parts, and Supplies, Net	(d) Aircraft Fuel, Spare Parts, and Supplies, Net
	Aircraft fuel, spare parts, and supplies, net are recorded at net realizable value based on average costs. These items are expensed when used. An allowance for obsolescence is provided for aircraft spare parts and supplies.
Operating Property and Equipment	(e) Operating Property and Equipment
	Operating property and equipment are recorded at cost. Interest expense related to the acquisition of certain property and equipment, including aircraft purchase deposits, is capitalized as an additional cost of the asset. Interest capitalized for the years ended December 31, 2014, 2013 and 2012 was $53 million, $47 million and $50 million, respectively. Property and equipment is depreciated and amortized to residual values over the estimated useful lives or the lease term, whichever is less, using the straight-line method. Costs of major improvements that enhance the usefulness of the asset are capitalized and depreciated over the estimated useful life of the asset or the modifications, whichever is less. The depreciable lives used for the principal depreciable asset classifications are:
	Principal Depreciable Asset Classification		Depreciable Life
	Jet aircraft and engines		16—30 years
	Other regional aircraft and engines		25 years
	Major rotable parts, avionics and assemblies		Fleet end date
	Improvements to leased flight equipment		Lesser of asset/leasehold improvement or lease end date
	Buildings and improvements (principally on leased land)		Lesser of 5—30 years or lease term
	Furniture, fixtures and other equipment		3—10 years: ranges from computer hardware to furniture
	Capitalized software		Lesser of 5 years or lease term
	Residual values for aircraft, engines, major rotable parts, avionics and assemblies are generally 5% to 10%.
	Equipment and property under capital leases are amortized over the term of the leases or, in the case of certain aircraft, over their expected useful lives. Lease terms vary but are generally 16 to 30 years for aircraft and three to 30 years for other leased equipment and property.
	American records impairment charges on long-lived assets used in operations when events and circumstances indicate that the assets may be impaired. An asset or group of assets is considered impaired when the undiscounted cash flows estimated to be generated by the asset are less than the carrying amount of the asset and the net book value of the asset exceeds its estimated fair value. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less cost to sell.
Income Taxes	(f) Income Taxes
	Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. A valuation allowance is established, if necessary, for the amount of any tax benefits that, based on available evidence, are not expected to be realized.
Other Intangibles, Net	(g) Other Intangibles, Net
	Intangible assets consist primarily of airport take-off and landing rights (Slots), international Slots and route authorities and gate leasehold rights. Intangible assets with estimable useful lives are amortized over their respective estimated useful lives to their estimated residual values and reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable.
	The following table provides information relating to American’s amortizable intangible assets as of December 31, 2014 and 2013 (in millions):
			December 31,
			2014			2013
	Airport Slots		$	310		$	277
	Airport gate leasehold rights			138			155
	Accumulated amortization			(376	)		(375	)
	Total		$	72		$	57
	Airport operating and gate lease rights are amortized on a straight-line basis over 25 years to a zero residual value.
	American recorded amortization expense related to these intangible assets of approximately $14 million, $18 million and $25 million for the years ended December 31, 2014, 2013 and 2012, respectively. American expects to record annual amortization expense for the aforementioned definite-life intangible assets as follows (in millions):
	2015		$	12
	2016			11
	2017			7
	2018			3
	2019			3
	2020 and thereafter			36
	Total		$	72
	American’s indefinite-lived assets include certain international route authorities and domestic airport take-off and landing slots. Indefinite-lived assets are not amortized but instead are reviewed for impairment annually and more frequently if events or circumstances indicate that the asset may be impaired. As of December 31, 2014 and 2013, American had $743 million and $755 million, respectively, of indefinite-lived intangible assets on its consolidated balance sheets.
	American’s indefinite-lived intangible assets are reviewed for impairment by initially performing a qualitative screen to determine whether American believes it is more likely than not that an asset has been impaired. If American believes an impairment has occurred, American then evaluates for impairment by comparing the estimated fair value of assets to the carrying value. An impairment charge is recognized if the asset’s estimated fair value is less than its carrying value. Based upon American’s annual testing, there was no indefinite-lived intangible asset impairment in 2014.
	Slot Divestitures
	As a stipulation for the Merger to be approved by the Department of Justice (DOJ), American was required to divest certain Slots at LaGuardia Airport and Ronald Reagan Washington National Airport (DCA). As of December 31, 2013, the DCA Slots to be divested were recorded as assets held for sale and were included in prepaid expenses and other on the consolidated balance sheet. In 2014, American divested the required DCA Slots and received $299 million in cash as well as 24 Slots at JFK. American recognized a gain of $305 million related to these divestitures, which has been included in special items, net in the consolidated statement of operations. In 2013, American recognized a gain of $67 million related to the sale of the LaGuardia Airport Slots, which has been included in special items, net in the consolidated statement of operations.
	In 2013, the European Commission cleared under the EU Merger Regulation the proposed merger between US Airways and American. As a consequence of the merger clearance process in the EU, American was required to make available one pair of London Heathrow Slots for use by another carrier between London and Philadelphia, which the acquiring carrier can deploy on another Heathrow city pair after operating the Slots on London-Philadelphia for a period of not less than three consecutive years. In addition, along with American’s joint business agreement (JBA) partners, American was required to make available for an initial period of up to seven years one pair of Heathrow Slots for service between London and Miami that may be operated via an intermediate point. In connection with these requirements and upon making these slots available, in 2014, American recorded a $43 million non-cash charge, which has been included in special items, net in the consolidated statement of operations.
Frequent Flyer Programs	(h) Frequent Flyer Program
	American currently operates the AAdvantage frequent flyer program. This program awards mileage credits to passengers who fly on American and oneworld carriers, as well as certain other partner airlines that participate in the programs. Mileage credits can also be earned through purchases from other non-airline partners that participate in American’s loyalty program. Mileage credits can be redeemed for travel on American, US Airways or other participating partner airlines, in which case American pays a fee.
	American uses the incremental cost method to account for the portion of American’s frequent flyer liability incurred when AAdvantage members earn mileage credits by flying on American or its regional affiliates. American has an obligation to provide future travel when these mileage credits are redeemed and therefore has recorded a liability for mileage credits outstanding.
	The incremental cost liability includes all mileage credits that are expected to be redeemed, including mileage credits earned by members whose mileage account balances have not yet reached the minimum mileage credit level required to redeem an award. Additionally, outstanding mileage credits are subject to expiration if unused. In calculating the liability, American estimates how many mileage credits will never be redeemed for travel and excludes those mileage credits from the estimate of the liability. Estimates are also made for the number of miles that will be used per award redemption and the number of travel awards that will be redeemed on partner airlines. These estimates are based on historical program experience as well as consideration of enacted program changes, as applicable. Changes in the liability resulting from members earning additional mileage credits or changes in estimates are recorded in the statement of operations as a part of passenger revenue.
	The liability for outstanding mileage credits is valued based on the estimated incremental cost of carrying one additional passenger. Incremental cost primarily includes unit costs incurred for fuel, food, and insurance as well as fees incurred when travel awards are redeemed on partner airlines. No profit or overhead margin is included in the accrual of incremental cost. These estimates are generally updated based upon American’s 12-month historical average of such costs.
	As of December 31, 2014 and 2013 the liability for outstanding mileage credits for the AAdvantage program was $647 million and $580 million, respectively, and is included on the consolidated balance sheets within frequent flyer liability.
	American also sells frequent flyer program mileage credits to participating airline partners and non-airline business partners. Sales of mileage credits to business partners is comprised of two components, transportation and marketing. Historically, American has used the residual method of accounting to determine the values of each component as there had not been a material modification to any significant agreements since the adoption of Accounting Standards Update (ASU) No. 2009-13, “Revenue Recognition (Topic 605) – Multiple-Deliverable Revenue Arrangements” on January 1, 2011.
	In 2013, American and Citibank amended their current AAdvantage co-branded credit card agreement which resulted in a material modification of the terms of the arrangement. Therefore, subsequent to the amendment of the arrangement, American applied the relative selling price method to determine the values of each deliverable. Under the relative selling price approach, American identified five revenue elements for the co-branded credit card agreements with Citibank: the transportation component; use of American’s brand including access to frequent flyer member lists; advertising; lounge access; and baggage services (together excluding “the transportation component,” the “marketing component”).
	The transportation component represents the estimated selling price of future travel awards and is determined using historical transaction information, including information related to customer redemption patterns. The transportation component is deferred based on its relative selling price and amortized into passenger revenue on a straight-line basis over the period in which the mileage credits are expected to be redeemed for travel.
	The marketing component represents services provided to American’s business partners and relates primarily to the use of American’s logo and tradename along with access to customers lists of AAdvantage members. The marketing services are provided periodically, but no less than monthly. Accordingly, the marketing component is considered earned and recognized in other revenues in the period of the mileage sale.
	Upon application of the relative selling price method in 2013 for American’s Citibank modification, American reduced its travel component liability and recorded other revenue of approximately $31 million. As a result of the change in the marketing component value when the relative selling price method is applied, American now defers less revenue per mile sold. For American’s agreements where there has not been a material modification, it continues to apply the residual method.
	As of December 31, 2014 and 2013, American had $1.2 billion in deferred revenue from the sale of mileage credits (recorded as frequent flyer liability on the consolidated balance sheets). For the years ended December 31, 2014, 2013 and 2012, the marketing component of mileage sales recognized at the time of sale in other revenues was approximately $1.1 billion, $816 million and $725 million, respectively.
Passenger Revenue	(i) Passenger Revenue
	Passenger ticket sales are initially recorded as a component of air traffic liability. Revenue derived from ticket sales is recognized at the time service is provided. However, due to various factors, including the complex pricing structure and interline agreements throughout the industry, certain amounts are recognized in revenue using estimates regarding both the timing of the revenue recognition and the amount of revenue to be recognized, including breakage. These estimates are generally based upon the evaluation of historical trends, including the use of regression analysis and other methods to model the outcome of future events based on American’s historical experience, and are recorded at the scheduled time of departure.
	American purchases capacity, or ASMs, generated by AAG’s wholly-owned regional air carrier and the capacity of Republic Airways Holdings’ subsidiaries Republic Airlines (Republic) and Chautauqua Airlines (Chautauqua), and SkyWest Airlines, Inc.‘s subsidiaries Sky West Airlines (SkyWest) and ExpressJet Airlines (ExpressJet) in certain markets. AAG’s wholly-owned regional air carrier and Chautauqua, ExpressJet, Republic, and SkyWest operate regional aircraft in these markets as part of American Eagle carriers. American classifies revenues generated from transportation on these carriers as regional passenger revenues. Liabilities related to tickets sold by American for travel on these air carriers are also included in American’s air traffic liability and are subsequently relieved in the same manner as described above.
	Various taxes and fees assessed on the sale of tickets to end customers are collected by American as an agent and remitted to taxing authorities. These taxes and fees have been presented on a net basis in the accompanying consolidated statements of operations and recorded as a liability until remitted to the appropriate taxing authority.
Maintenance, Materials and Repairs	(j) Maintenance, Materials and Repairs
	Maintenance and repair costs for owned and leased flight equipment are charged to operating expense as incurred, except costs incurred for maintenance and repair under flight hour maintenance contract agreements, which are accrued based on contractual terms when an obligation exists.
Selling Expenses	(k) Selling Expenses
	Selling expenses include commissions, credit card fees, computerized reservations systems fees and advertising. Advertising expenses are expensed as incurred. Advertising expense was $86 million, $166 million and $153 million for the years ended December 31, 2014, 2013 and 2012, respectively.
Share-based Compensation	(l) Share-based Compensation
	American accounts for its share-based compensation expense based on the fair value of the stock award at the time of grant, which is recognized ratably over the vesting period of the stock award. The fair value of stock options and stock appreciation rights is estimated using a Black-Scholes option pricing model. The fair value of restricted stock units is based on the market price of the underlying shares of common stock on the date of grant. See Note 15 for further discussion of share-based compensation.

In addition, the Company recorded a $107 million charge related to American’s pilot long-term disability obligation, a $43 million charge for workers’ compensation claims and a $33 million aircraft impairment charge. These charges were offset in part by a $67 million gain on the sale of slots at LaGuardia Airport.
	The 2012 mainline operating special items, net primarily consisted of $386 million of severance and related charges and write-off of leasehold improvements on aircraft and airport facilities that were rejected in connection with the Chapter 11 Cases.

	-1	The 2013 other revenue special item, net included a credit to other revenues related to a change in accounting method resulting from the modification of AAG’s AAdvantage miles agreement with Citibank.
	-2	The 2014 nonoperating special items totaled a net charge of $132 million, which principally included a $43 million charge for Venezuelan foreign currency losses, $56 million of early debt extinguishment costs related to the prepayment of 7.50% senior secured notes and other indebtedness and $33 million of non-cash interest accretion on bankruptcy settlement obligations. See Note 12 for further discussion on Venezuela cash and short-term investments.
	The 2013 nonoperating special items, net consisted of interest charges of $138 million to recognize post-petition interest expense on unsecured obligations pursuant to the Plan and penalty interest related to 10.5% secured notes and 7.50% senior secured notes, a $54 million charge related to the premium on tender for existing enhanced equipment trust certificates financings and the write-off of debt issuance costs, and $19 million in charges related to the repayment of existing EETC financings.
	The 2012 nonoperating special items, net consisted of a $280 million benefit resulting from a settlement of a commercial dispute.
	-3	In 2013 and 2012, the Company recognized reorganization expenses as a result of the filing of voluntary petitions for relief under Chapter 11. These amounts consisted primarily of estimated allowed claim amounts and professional fees.
	-4	In 2014, special tax items, net were $346 million. During 2014, the Company sold its portfolio of fuel hedging contracts that were scheduled to settle on or after June 30, 2014. In connection with this sale, the Company recorded a special non-cash tax provision of $330 million in the second quarter of 2014 that reversed the non-cash tax provision which was recorded in other comprehensive income (OCI), a subset of stockholders’ equity, principally in 2009. This provision represents the tax effect associated with gains recorded in OCI principally in 2009 due to a net increase in the fair value of the Company’s fuel hedging contracts. In accordance with GAAP, the Company retained the $330 million tax provision in OCI until the last contract was settled or terminated. In addition, the 2014 period included a special $16 million non-cash deferred income tax provision related to certain indefinite-lived intangible assets.
	In 2013 and 2012, income tax special items, net included, respectively, a $538 million and a $569 million non-cash income tax benefit from continuing operations. The Company is required to consider all items (including items recorded in other comprehensive income) in determining the amount of tax benefit that results from a loss from continuing operations and that should be allocated to continuing operations. As a result, the Company recorded a tax benefit on the loss from continuing operations for the year, which was exactly offset by income tax expense on other comprehensive income. However, while the income tax benefit from continuing operations is reported on the income statement, the income tax expense on other comprehensive income is recorded directly to accumulated other comprehensive income (loss), which is a component of stockholders’ equity. Because the income tax expense on other comprehensive income is equal to the income tax benefit from continuing operations, the Company’s year-end net deferred tax position is not impacted by this tax allocation. The 2013 tax benefit was offset in part by a $214 million tax charge attributable to additional valuation allowance required to reduce deferred tax assets to the amount the Company believes is more likely than not to be realized.

	(a)	In March 2014, the Company notified the holders of US Airways Group’s 7.25% convertible senior notes that it had elected to settle all future conversions solely in cash instead of shares of AAG Common Stock in accordance with the related indenture. Thus, the diluted shares include the weighted average impact of the 7.25% convertible senior notes only for the period from January 1, 2014 to March 12, 2014. In addition, under GAAP, the Company must adjust the numerator for purposes of calculating diluted earnings per share by the change in fair value of the conversion feature from March 12, 2014 to May 15, 2014, which increased GAAP net income for purposes of computing diluted earnings per share by $3 million for the year ended December 31, 2014.

	(a) 2013 Credit Facilities
	On June 27, 2013, American and AAG entered into a Credit and Guaranty Agreement (as amended, the 2013 Credit Agreement) with certain lenders. The 2013 Credit Agreement provides for a $1.9 billion term loan facility (the 2013 Term Loan Facility) that is scheduled to mature on June 27, 2019, unless otherwise extended by the applicable parties. As of December 31, 2014, American had borrowed $1.9 billion under the 2013 Term Loan Facility.
	The 2013 Credit Agreement originally provided for a $1.0 billion revolving credit facility (the 2013 Revolving Facility and, together with the 2013 Term Loan Facility, the 2013 Credit Facilities) scheduled to mature on June 27, 2018, unless otherwise extended by the applicable parties. The 2013 Term Loan Facility is repayable in quarterly installments in an amount equal to 0.25% of the original principal amount thereof with any unpaid balance due on the maturity date of the 2013 Term Loan Facility. The 2013 Revolving Facility provided that American may from time to time borrow, repay and reborrow loans thereunder and have letters of credit issued thereunder in an aggregate amount outstanding at any time of up to $1.0 billion. On October 10, 2014, American and AAG amended the 2013 Credit Agreement to extend the maturity date of the 2013 Revolving Facility to October 10, 2019 and increased the commitments thereunder to an aggregate amount of $1.4 billion while reducing the letter of credit commitments thereunder to $300 million. As of December 31, 2014, there were no borrowings or letters of credit outstanding under the 2013 Revolving Facility.
	The 2013 Credit Facilities bear interest at an index rate plus an applicable index margin or, at American’s option, LIBOR (subject to a floor of 0.75%, with respect to the 2013 Term Loan Facility) plus an applicable LIBOR margin. The applicable LIBOR margin is 3.00% for borrowings under both the 2013 Term Loan Facility and the 2013 Revolving Facility.
	Upon consummation of the Merger, US Airways Group and US Airways joined the 2013 Credit Facilities as guarantors. Following the joinder, certain minimum dollar-thresholds under the negative and financial covenants in the 2013 Credit Facilities were automatically increased. Subject to certain limitations and exceptions, the 2013 Credit Facilities are secured by certain collateral, including certain route authorities and certain take-off and landing rights and gate leaseholds at certain airports. American is required to maintain a certain minimum ratio of appraised value of the collateral to the outstanding loans under the 2013 Credit Facilities as more fully described below in “Collateral Related Covenants.” The 2013 Credit Facilities contain events of default customary for similar financings, including cross default to other material indebtedness. Upon the occurrence of an event of default, the outstanding obligations under the 2013 Credit Facilities may be accelerated and become due and payable immediately. In addition, if a “change of control” (as defined in the 2013 Credit Agreement) occurs, American will (absent an amendment or waiver) be required to repay at par the loans outstanding under the 2013 Credit Facilities and terminate the 2013 Revolving Facility. The 2013 Credit Facilities also include covenants that, among other things, require AAG to maintain a minimum aggregate liquidity (as defined in the 2013 Credit Facilities) of not less than $2.0 billion, and limit the ability of AAG and its restricted subsidiaries to pay dividends and make certain other payments, make certain investments, incur additional indebtedness, incur liens on the collateral, dispose of the collateral, enter into certain affiliate transactions and engage in certain business activities, in each case subject to certain exceptions.
	(b) 2014 Credit Facilities
	On October 10, 2014, American, AAG, US Airways Group and US Airways entered into a Credit and Guaranty Agreement (the 2014 Credit Agreement) with certain lenders. The 2014 Credit Agreement provides for a $750 million term loan facility (the 2014 Term Loan Facility), which was fully drawn on October 10, 2014, and a $400 million revolving credit facility (the 2014 Revolving Facility and, together with the 2014 Term Loan Facility, the 2014 Credit Facilities). The 2014 Revolving Facility provides that American may from time to time borrow, repay and reborrow loans thereunder. American may have letters of credit issued under the 2014 Revolving Facility in an aggregate amount outstanding at any time up to $300 million. There are currently no borrowings or letters of credit outstanding under the 2014 Revolving Facility.
	Subject to certain limitations and exceptions, the 2014 Credit Facilities are secured by certain collateral, including certain route authorities and certain take-off and landing rights and gate leaseholds at certain airports. The obligations of American under the 2014 Credit Facilities are guaranteed by AAG, US Airways Group and US Airways. American is required to maintain a certain minimum ratio of appraised value of the collateral to the outstanding loans under the 2014 Credit Facilities as more fully described below in “Collateral Related Covenants.” Mandatory prepayments at par of term loans and revolving loans may be required to the extent necessary to comply with American’s covenants regarding the collateral coverage ratio.
	The 2014 Term Loan Facility and 2014 Revolving Facility mature on October 10, 2021 and October 10, 2019, respectively, unless otherwise extended by the applicable parties. The 2014 Term Loan Facility is repayable in annual installments in an amount equal to 1.00% of the original principal balance with any unpaid balance due on the maturity date of the 2014 Term Loan Facility. Voluntary prepayments may be made by American at any time, with a premium of 1.00% applicable to certain prepayments made prior to the date that is six months following October 10, 2014. In addition, if a “change of control” (as defined in the 2014 Credit Agreement) occurs with respect to AAG, American will (absent an amendment or waiver) be required to repay at par the loans outstanding under the 2014 Credit Facilities and terminate the 2014 Revolving Facility.
	The 2014 Credit Facilities bear interest at an index rate plus an applicable index margin or, at American’s option, LIBOR (subject to a floor of 0.75% in the case of the 2014 Term Loan Facility) plus an applicable LIBOR margin. The applicable LIBOR margins are 3.50% and 3.00% for borrowings under the 2014 Term Loan Facility and the 2014 Revolving Facility, respectively. If American has a corporate credit rating of Ba3 or higher from Moody’s and BB- or higher from S&P, the applicable LIBOR margin is 3.25% under the 2014 Term Loan Facility.
	The 2014 Credit Facilities contain events of default customary for similar financings, including cross default to other material indebtedness. Upon the occurrence of an event of default, the outstanding obligations under the 2014 Credit Facilities may be accelerated and become due and payable immediately. The 2014 Credit Facilities also include covenants that, among other things, require AAG to maintain a minimum aggregate liquidity (as defined in the 2014 Credit Facilities) of not less than $2.0 billion, and limit the ability of AAG and its restricted subsidiaries to pay dividends and make certain other payments, make certain investments, incur liens on the collateral, dispose of the collateral, enter into certain affiliate transactions and engage in certain business activities, in each case subject to certain exceptions.
	(c) 2013 Citicorp Credit Facility
	US Airways Group and certain other subsidiaries of US Airways Group are guarantors of the 2013 Citicorp Credit Facility agreement dated as of May 23, 2013. In connection with the closing of the Merger, AAG and American entered into a joinder to the 2013 Citicorp Credit Facility loan agreement pursuant to which AAG and American became guarantors under such agreement.
	The 2013 Citicorp Credit Facility consists of $1.0 billion of tranche B-1 term loans (Tranche B-1) and $600 million of tranche B-2 term loans (Tranche B-2). Voluntary prepayments may be made at any time, with a premium of 1.00% applicable to certain prepayments made prior to the date that is six months following January 16, 2014. Mandatory prepayments of the term loans are required to the extent necessary to comply with US Airways’ covenants regarding the collateral coverage ratio and certain dispositions of collateral. In addition, under the 2013 Citicorp Credit Facility agreement, if a “change of control” (as defined in the 2013 Citicorp Credit Facility agreement) occurs, US Airways will (absent an amendment or waiver) be required to repay the outstanding loans in full together with accrued interest thereon to the date of such prepayment.
	As of December 31, 2014, the 2013 Citicorp Credit Facility bears interest at an index rate plus an applicable index margin or, at US Airways’ option, LIBOR (subject to a floor of 0.75%) plus an applicable LIBOR margin. The applicable LIBOR margin is 2.75% for Tranche B-1 and 2.25% for Tranche B-2.
	Tranche B-1 and Tranche B-2 mature on May 23, 2019 and November 23, 2016, respectively (unless otherwise extended by the applicable parties), and each is repayable in annual installments to be paid on each anniversary of the closing date in an amount equal to 1.00% of the initial aggregate principal amount of the loans with any unpaid balance due on the maturity date of the respective tranche.
	The obligations of US Airways under the 2013 Citicorp Credit Facility are secured by liens on certain take-off and landing rights at certain airports and certain other assets of US Airways. US Airways is required to maintain a certain minimum ratio of appraised value of the collateral to the outstanding loans under the 2013 Citicorp Credit Facility agreement as more fully described below in “Collateral Related Covenants”.
	The 2013 Citicorp Credit Facility agreement includes affirmative, negative and financial covenants that, among other things, (a) require AAG and its restricted subsidiaries to maintain unrestricted liquidity of not less than $2.0 billion, with not less than $750 million held in accounts subject to control agreements, and (b) restrict the ability of US Airways Group, its subsidiaries party to the 2013 Citicorp Credit Facility, AAG and American to make certain investments, pay dividends and make certain other payments, make certain acquisitions, incur liens on the collateral, dispose of collateral, enter into certain affiliate transactions, enter into certain hedging transactions, and engage in certain business activities, in each case subject to certain exceptions. The 2013 Citicorp Credit Facility agreement contains events of default customary for similar financings, including a cross default provision to certain other material indebtedness of US Airways and certain of its affiliates. Upon the occurrence of an event of default, the outstanding obligations under the 2013 Citicorp Credit Facility may be accelerated and become due and payable immediately.
	(d) Aircraft Enhanced Equipment Trust Certificates (EETCs)
	2014-1 EETCs
	In September 2014, American created two pass-through trusts which issued approximately $957 million aggregate face amount of Series 2014-1 Class A and Class B EETCs in connection with the financing of 17 aircraft recently delivered to, and owned by, American (the 2014 EETC Aircraft).
	As of December 31, 2014, the full $957 million of the escrowed proceeds from the 2014-1 EETCs have been used to purchase equipment notes issued by American in two series: Series A equipment notes in the amount of $742 million bearing interest at 3.70% per annum and Series B equipment notes in the amount of $215 million bearing interest at 4.375% per annum. Interest and principal payments on the equipment notes are scheduled to be made in April and October of each year, beginning in April 2015. The final payments on the Series A and Series B equipment notes will be due in October 2026 and October 2022, respectively. The equipment notes are secured by liens on the 2014 EETC Aircraft.
	2013-1 EETCs
	During 2014, US Airways issued $559 million of equipment notes in two series under its 2013-1 EETCs completed in April 2013: Series A equipment notes in the amount of $423 million bearing interest at 3.95% per annum and Series B equipment notes in the amount of $136 million bearing interest at 5.375% per annum. As of December 31, 2014, the full $820 million of the escrowed proceeds from US Airways’ 2013-1 EETCs have been used to purchase Series A and Series B equipment notes issued by US Airways. The equipment notes are secured by liens on aircraft.
	(e) Other Aircraft Financing Transactions
	In May 2014, the Company prepaid $113 million principal amount of outstanding debt secured by certain aircraft.
	During 2014, American entered into loan agreements to borrow $286 million in connection with financing certain aircraft deliveries. The notes mature in 2026 and bear interest at a rate of LIBOR plus an applicable margin.
	During 2014, American financed 20 Boeing 737-800 aircraft under sale-leaseback arrangements and recorded proceeds from the sale of $811 million. Of the 20 Boeing 737-800 aircraft, 19 aircraft were accounted for as a capital lease and $747 million was reflected as debt on the consolidated balance sheet, included within other secured obligations in the table above. Gains associated with these sale-leaseback transactions are amortized over the respective remaining lease term and are included in the consolidated balance sheet as deferred gains.
	(f) Obligations Associated with Special Facility Revenue Bonds
	In 2014, the Company prepaid $314 million of obligations, of which $135 million was a reduction of debt on the Company’s balance sheet, associated with special facility revenue bonds issued by municipalities to build or improve certain airport and maintenance facilities. The remaining portion of these obligations was accounted for as an operating lease.
	In addition, in August 2014, American elected to exercise its option to reset the interest rate on approximately $220 million aggregate principal amount of special facility revenue bonds reflected as debt on its balance sheet, related to the Los Angeles International Airport, resulting in the repurchase of these bonds by American in September 2014. American has the option to remarket these bonds in the future. In connection with the repurchase of these bonds, American paid $2 million in cash premiums and recorded a $5 million non-cash write off of unamortized debt discount and issuance costs.
	In December 2014, American purchased approximately $112 million aggregate principal amount of special facility revenue bonds related to the Tulsa International Airport, when such bonds were mandatorily tendered to American. Of this amount, $11 million was a reduction of debt on American’s balance sheet. American has the option to remarket these bonds in the future.
	(g) Senior Secured Notes
	In March 2014, American prepaid $100 million of its 7.50% senior secured notes at a redemption price of 103% of their principal amount plus accrued and unpaid interest. In July 2014, American prepaid the remaining outstanding principal balance of $900 million at a redemption price of 103.75% of outstanding principal amount plus accrued and unpaid interest. In connection with the prepayment of the outstanding 7.50% senior secured notes, American paid $37 million of cash premiums and recorded a $5 million non-cash write off of unamortized deferred issuance costs during the year ended December 31, 2014.
	(h) AAdvantage Loan
	In 2009, American entered into an arrangement under which Citibank loaned American $1.0 billion that could be repaid either in AAdvantage miles under American’s AAdvantage program or in cash (the AAdvantage Loan). Approximately $890 million of the AAdvantage Loan proceeds was accounted for as a loan from Citibank with the remaining $110 million recorded as deferred revenue in other liabilities and deferred credits.
	To effect the AAdvantage Loan, American and Citibank entered into an Amended and Restated AAdvantage Participation Agreement (as so amended and restated, the Amended Participation Agreement). Under the Amended Participation Agreement, American agreed that it would apply in equal monthly installments over a five year period beginning on January 1, 2012, a credit for miles awarded to Citibank cardholders’ AAdvantage accounts.
	American had the right to repay in cash, without premium or penalty, any or all of the amounts owed to Citibank under the AAdvantage Loan. Effective January 2, 2015, American exercised its loan repayment right with respect to the full value of the outstanding balance to Citibank for $400 million. In connection with the repayment, in the first quarter of 2015, American will recognize an early debt extinguishment gain of approximately $17 million. The entire outstanding balance of the obligation is reflected in current maturities of long-term debt on the accompanying consolidated balance sheet as of December 31, 2014.
	(i) 5.50% Senior Notes
In September 2014, the Company issued $750 million aggregate principal amount of 5.50% senior notes due 2019 (the 5.50% senior notes). These notes bear interest at a rate of 5.50% per annum, which is payable semi-annually in arrears on each April 1 and October 1, beginning April 1, 2015. The 5.50% senior notes mature on October 1, 2019 and are fully and unconditionally guaranteed by American, US Airways Group and US Airways. The 5.50% senior notes are senior unsecured obligations of the Company. The indenture for the 5.50% senior notes contains covenants and events of default generally customary for similar financings. In addition, if the Company experiences specific kinds of changes of control, the Company must offer to repurchase the 5.50% senior notes at a price of 101% of the principal amount plus accrued and unpaid interest, if any, to the repurchase date. Upon the occurrence of certain events of default, the 5.50% senior notes may be accelerated and become due and payable.
(j) 6.125% Senior Notes
In May 2013, US Airways Group issued its 6.125% Senior Notes due 2018 (the 6.125% senior notes). The 6.125% senior notes bear interest at a rate of 6.125% per annum, which is payable semi-annually on each June 1 and December 1 and began December 1, 2013. The 6.125% senior notes mature on June 1, 2018 and are fully and unconditionally guaranteed by US Airways. In connection with the closing of the Merger, AAG and American provided a full and unconditional guarantee of the payment obligations of US Airways Group under the 6.125% senior notes. The 6.125% senior notes are general unsecured senior obligations of the Company.
(k) 7.25% Convertible Notes
In March 2014, the Company notified the holders of US Airways Group’s 7.25% convertible notes that it had elected to settle solely in cash instead of shares of AAG Common Stock all conversions during the period beginning on March 15, 2014 and ending on, and including, the second scheduled trading day immediately preceding the maturity date of May 15, 2014. In May 2014, the Company settled all outstanding 7.25% convertible notes in cash for approximately $175 million.

	(a) 2013 Credit Facilities
	On June 27, 2013, American and AAG entered into a Credit and Guaranty Agreement (as amended, the 2013 Credit Agreement) with certain lenders. The 2013 Credit Agreement provides for a $1.9 billion term loan facility (the 2013 Term Loan Facility) that is scheduled to mature on June 27, 2019, unless otherwise extended by the applicable parties. As of December 31, 2014, American had borrowed $1.9 billion under the 2013 Term Loan Facility.
	The 2013 Credit Agreement originally provided for a $1.0 billion revolving credit facility (the 2013 Revolving Facility and, together with the 2013 Term Loan Facility, the 2013 Credit Facilities) scheduled to mature on June 27, 2018, unless otherwise extended by the applicable parties. The 2013 Term Loan Facility is repayable in quarterly installments in an amount equal to 0.25% of the original principal amount thereof with any unpaid balance due on the maturity date of the 2013 Term Loan Facility. The 2013 Revolving Facility provided that American may from time to time borrow, repay and reborrow loans thereunder and have letters of credit issued thereunder in an aggregate amount outstanding at any time of up to $1.0 billion. On October 10, 2014, American and AAG amended the 2013 Credit Agreement to extend the maturity date of the 2013 Revolving Facility to October 10, 2019 and increased the commitments thereunder to an aggregate amount of $1.4 billion while reducing the letter of credit commitments thereunder to $300 million. As of December 31, 2014, there were no borrowings or letters of credit outstanding under the 2013 Revolving Facility.
	The 2013 Credit Facilities bear interest at an index rate plus an applicable index margin or, at American’s option, LIBOR (subject to a floor of 0.75%, with respect to the 2013 Term Loan Facility) plus an applicable LIBOR margin. The applicable LIBOR margin is 3.00% for borrowings under both the 2013 Term Loan Facility and the 2013 Revolving Facility.
	Upon consummation of the Merger, US Airways Group and US Airways joined the 2013 Credit Facilities as guarantors. Following the joinder, certain minimum dollar-thresholds under the negative and financial covenants in the 2013 Credit Facilities were automatically increased. Subject to certain limitations and exceptions, the 2013 Credit Facilities are secured by certain collateral, including certain route authorities and certain take-off and landing rights and gate leaseholds at certain airports. American is required to maintain a certain minimum ratio of appraised value of the collateral to the outstanding loans under the 2013 Credit Facilities as more fully described below in “Collateral Related Covenants.” The 2013 Credit Facilities contain events of default customary for similar financings, including cross default to other material indebtedness. Upon the occurrence of an event of default, the outstanding obligations under the 2013 Credit Facilities may be accelerated and become due and payable immediately. In addition, if a “change of control” (as defined in the 2013 Credit Agreement) occurs, American will (absent an amendment or waiver) be required to repay at par the loans outstanding under the 2013 Credit Facilities and terminate the 2013 Revolving Facility. The 2013 Credit Facilities also include covenants that, among other things, require AAG to maintain a minimum aggregate liquidity (as defined in the 2013 Credit Facilities) of not less than $2.0 billion, and limit the ability of AAG and its restricted subsidiaries to pay dividends and make certain other payments, make certain investments, incur additional indebtedness, incur liens on the collateral, dispose of the collateral, enter into certain affiliate transactions and engage in certain business activities, in each case subject to certain exceptions.
	(b) 2014 Credit Facilities
	On October 10, 2014, American, AAG, US Airways Group and US Airways entered into a Credit and Guaranty Agreement (the 2014 Credit Agreement) with certain lenders. The 2014 Credit Agreement provides for a $750 million term loan facility (the 2014 Term Loan Facility), which was fully drawn on October 10, 2014, and a $400 million revolving credit facility (the 2014 Revolving Facility and, together with the 2014 Term Loan Facility, the 2014 Credit Facilities). The 2014 Revolving Facility provides that American may from time to time borrow, repay and reborrow loans thereunder. American may have letters of credit issued under the 2014 Revolving Facility in an aggregate amount outstanding at any time up to $300 million. There are currently no borrowings or letters of credit outstanding under the 2014 Revolving Facility.
	Subject to certain limitations and exceptions, the 2014 Credit Facilities are secured by certain collateral, including certain route authorities and certain take-off and landing rights and gate leaseholds at certain airports. The obligations of American under the 2014 Credit Facilities are guaranteed by AAG, US Airways Group and US Airways. American is required to maintain a certain minimum ratio of appraised value of the collateral to the outstanding loans under the 2014 Credit Facilities as more fully described below in “Collateral Related Covenants.” Mandatory prepayments at par of term loans and revolving loans may be required to the extent necessary to comply with American’s covenants regarding the collateral coverage ratio.
	The 2014 Term Loan Facility and 2014 Revolving Facility mature on October 10, 2021 and October 10, 2019, respectively, unless otherwise extended by the applicable parties. The 2014 Term Loan Facility is repayable in annual installments in an amount equal to 1.00% of the original principal balance with any unpaid balance due on the maturity date of the 2014 Term Loan Facility. Voluntary prepayments may be made by American at any time, with a premium of 1.00% applicable to certain prepayments made prior to the date that is six months following October 10, 2014. In addition, if a “change of control” (as defined in the 2014 Credit Agreement) occurs with respect to AAG, American will (absent an amendment or waiver) be required to repay at par the loans outstanding under the 2014 Credit Facilities and terminate the 2014 Revolving Facility.
	The 2014 Credit Facilities bear interest at an index rate plus an applicable index margin or, at American’s option, LIBOR (subject to a floor of 0.75% in the case of the 2014 Term Loan Facility) plus an applicable LIBOR margin. The applicable LIBOR margins are 3.50% and 3.00% for borrowings under the 2014 Term Loan Facility and the 2014 Revolving Facility, respectively. If American has a corporate credit rating of Ba3 or higher from Moody’s and BB- or higher from S&P, the applicable LIBOR margin is 3.25% under the 2014 Term Loan Facility.
	The 2014 Credit Facilities contain events of default customary for similar financings, including cross default to other material indebtedness. Upon the occurrence of an event of default, the outstanding obligations under the 2014 Credit Facilities may be accelerated and become due and payable immediately. The 2014 Credit Facilities also include covenants that, among other things, require AAG to maintain a minimum aggregate liquidity (as defined in the 2014 Credit Facilities) of not less than $2.0 billion, and limit the ability of AAG and its restricted subsidiaries to pay dividends and make certain other payments, make certain investments, incur liens on the collateral, dispose of the collateral, enter into certain affiliate transactions and engage in certain business activities, in each case subject to certain exceptions.
	(c) Aircraft Enhanced Equipment Trust Certificates (EETCs)
	2014-1 EETCs
	In September 2014, American created two pass-through trusts which issued approximately $957 million aggregate face amount of Series 2014-1 Class A and Class B EETCs in connection with the financing of 17 aircraft recently delivered to, and owned by, American (the 2014 EETC Aircraft).
	As of December 31, 2014, the full $957 million of the escrowed proceeds from the 2014-1 EETCs have been used to purchase equipment notes issued by American in two series: Series A equipment notes in the amount of $742 million bearing interest at 3.70% per annum and Series B equipment notes in the amount of $215 million bearing interest at 4.375% per annum. Interest and principal payments on the equipment notes are scheduled to be made in April and October of each year, beginning in April 2015. The final payments on the Series A and Series B equipment notes will be due in October 2026 and October 2022, respectively. The equipment notes are secured by liens on the 2014 EETC Aircraft.
	(d) Other Aircraft Financing Transactions
	In May 2014, American prepaid $61 million principal amount of outstanding debt secured by certain aircraft.
	During 2014, American entered into loan agreements to borrow $286 million in connection with financing certain aircraft deliveries. The notes mature in 2026 and bear interest at a rate of LIBOR plus an applicable margin.
	During 2014, American financed 20 Boeing 737-800 aircraft under sale-leaseback arrangements and recorded proceeds from the sale of $811 million. Of the 20 Boeing 737-800 aircraft, 19 aircraft were accounted for as a capital lease and $747 million was reflected as debt on the consolidated balance sheet, included within other secured obligations in the table above. Gains associated with these sale-leaseback transactions are amortized over the respective remaining lease term and are included in the consolidated balance sheet as deferred gains.
	(e) Obligations Associated with Special Facility Revenue Bonds
	During 2014, American prepaid $98 million of obligations, of which $62 million was a reduction of debt on its consolidated balance sheet, associated with special facility revenue bonds issued by municipalities to build or improve certain airport and maintenance facilities. The remaining portion of these obligations was accounted for as an operating lease.
	In addition, in August 2014, American elected to exercise its option to reset the interest rate on approximately $220 million aggregate principal amount of special facility revenue bonds reflected as debt on its balance sheet, related to the Los Angeles International Airport, resulting in the repurchase of these bonds by American in September 2014. American has the option to remarket these bonds in the future. In connection with the repurchase of these bonds, American paid $2 million in cash premiums and recorded a $5 million non-cash write off of unamortized debt discount and issuance costs.
	In December 2014, American purchased approximately $112 million aggregate principal amount of special facility revenue bonds related to the Tulsa International Airport, when such bonds were mandatorily tendered to American. Of this amount, $11 million was a reduction of debt on American’s balance sheet. American has the option to remarket these bonds in the future.
	(f) Senior Secured Notes
	In March 2014, American prepaid $100 million of its 7.50% senior secured notes at a redemption price of 103% of their principal amount plus accrued and unpaid interest. In July 2014, American prepaid the remaining outstanding principal balance of $900 million at a redemption price of 103.75% of outstanding principal amount plus accrued and unpaid interest. In connection with the prepayment of the outstanding 7.50% senior secured notes, American paid $37 million of cash premiums and recorded a $5 million non-cash write off of unamortized deferred issuance costs during the year ended December 31, 2014.
	(g) AAdvantage Loan
	In 2009, American entered into an arrangement under which Citibank loaned American $1.0 billion that could be repaid either in AAdvantage miles under American’s AAdvantage program or in cash (the AAdvantage Loan). Approximately $890 million of the AAdvantage Loan proceeds was accounted for as a loan from Citibank with the remaining $110 million recorded as deferred revenue in other liabilities and deferred credits.
	To effect the AAdvantage Loan, American and Citibank entered into an Amended and Restated AAdvantage Participation Agreement (as so amended and restated, the Amended Participation Agreement). Under the Amended Participation Agreement, American agreed that it would apply in equal monthly installments over a five year period beginning on January 1, 2012, a credit for miles awarded to Citibank cardholders’ AAdvantage accounts.
	American had the right to repay in cash, without premium or penalty, any or all of the amounts owed to Citibank under the AAdvantage Loan. Effective January 2, 2015, American exercised its loan repayment right with respect to the full value of the outstanding balance to Citibank for $400 million. In connection with the repayment, in the first quarter of 2015, American will recognize an early debt extinguishment gain of approximately $17 million. The entire outstanding balance of the obligation is reflected in current maturities of long-term debt on the accompanying consolidated balance sheet as of December 31, 2014.

	-1	The Company’s weighted average diluted shares outstanding for the 2013 quarters presented include the weighted effect of shares outstanding for both the pre and post-merger periods. The shares outstanding for the pre-merger periods (January 1, 2013 through December 8, 2013) consist only of the AMR common stock formerly traded under the symbol: “AAMRQ”. In accordance with GAAP, these former AAMRQ shares have been adjusted for all periods presented to retrospectively reflect the distributions made to date pursuant to the Company’s Plan, whereby holders of AAMRQ have received 0.7441 shares of AAG Common Stock per share of AAMRQ. The shares outstanding for the 23 day post-merger period (December 9, 2013 through December 31, 2013) include the full amount of shares to be issued pursuant to the Plan over the 120 day distribution period adjusted for approximately 13 million shares withheld by the Company in satisfaction of employee tax obligations.
	Former holders of AAMRQ shares as of the Effective Date may in the future receive additional distributions of AAG Common Stock dependent upon the ultimate distribution of shares of AAG Common Stock to holders of disputed claims. Thus, the shares and related earnings per share calculation prior to the Effective Date may change in the future to reflect additional retrospective adjustments for future AAG Common Stock distributions to former holders of AAMRQ shares.
