Emergence From Chapter 11	12 Months Ended

Reorganization [Line Items]	'
Emergence From Chapter 11	'
	Emergence From Chapter 11
	Overview
	On November 29, 2011 (the Petition Date), AMR Corporation (AMR) (renamed American Airlines Group Inc., AAG upon closing of the Merger, AAG and, together with its consolidated subsidiaries, the Company), its principal subsidiary, American Airlines, Inc. (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 the Company, AMR Merger Sub, Inc. (Merger Sub) and US Airways Group, Inc. (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 American Airlines Group common stock (AAG Common Stock), par value $0.01 per share.
	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 Corporation common stock outstanding prior to the Effective Date were canceled. The Restated Certificate of Incorporation, which was approved in connection with the Plan, authorizes the issuance of 1.75 billion new shares of AAG Common Stock, par value $0.01 per share, and 200 million shares of AAG Series A Preferred Stock, par value $0.01 per share. Of the authorized AAG Series A Preferred Stock, approximately 168 million were designated "Series A Convertible Preferred Stock", with a stated value $25.00 per share, and issued in accordance with the Plan. AAG Common Stock and AAG Series A Preferred Stock are listed on the NASDAQ Global Select Market under the symbols "AAL" and "AALCP", respectively, and began trading on December 9, 2013. In addition, pursuant to the Plan and the Merger agreement, up to 40 million shares of AAG common stock was authorized for issuance under the 2013 Incentive Award Plan (the 2013 IAP).
	The Plan contains the following provisions relating to the treatment of pre-petition claims against the Debtors and other holders of allowed interests in AMR Corporation:
	•	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 are 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, at the Effective Date, a portion of their recovery in shares of AAG Series A Preferred Stock and a right, subject to the trading price of the Company's common stock during the 120 day period after the Effective Date, to receive their remaining recovery in shares of AAG Common Stock 120 days 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, will receive additional shares of AAG Common Stock if, among other considerations, the trading price of the Company's common stock at various points during the 120 day period after the Effective Date provides for a full recovery to claimholders and other allowed priority interests; 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 (Disputed Claims Reserve), beginning after 120 days after the Effective Date. Disputed claimholders that subsequently become Single-Dip Unsecured Claimholders 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 Single-Dip Unsecured Claimholder as of the Effective Date.
	The Plan contemplates the distribution of up to 756 million shares of common stock of which approximately 53 million shares were issued to the Debtors' stakeholders in connection with the Effective Date. In accordance with the Plan, the Company will issue the remaining shares of AAG Common Stock over the 120 day distribution period and as disputed claims are resolved. In addition, pursuant to the Plan approximately 197 million common shares were distributed to holders of outstanding shares of US Airways Group common stock.
	Pursuant to rulings of the Bankruptcy Court, the Plan has established a disputed claim reserve to hold shares of AAG Series A Preferred Stock and AAG Common Stock reserved for issuance to disputed claimholders that ultimately become allowed Single-Dip general unsecured claimholders after emergence. The shares provided for under the Plan are determined based upon a disputed claim reserve amount of approximately $755 million, representing the maximum amount of additional allowable Single-Dip claims under the Plan's provisions. Approximately 16 million shares of AAG Series A Preferred Stock were reserved at the Effective Date for distribution to holders of disputed Single-Dip general unsecured claims whose claims ultimately become allowed. Additional new shares of AAG Common Stock will be distributed into the reserve on or about the 120th day after the Effective Date. As disputed claims are resolved, the claimants receive distributions of shares from the 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 the remaining disputed claims, such shares will not be returned to the Company but rather will be distributed by priority first, if necessary, to satisfy unsecured claims or labor-related obligations, and then to former AMR shareholders as of the Effective Date.
	We are not required to distribute additional shares above the 756 million shares contemplated by the Plan, even if the shares remaining for distribution are not sufficient to fully pay all allowed unsecured claims. However, resolution of disputed claims could have a material effect on Single-Dip creditor recoveries 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.
	In addition, as of December 31, 2013, the Company 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 Chapter 11 and interest and penalty interest thereon;
	•	$105 million 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 $300 million for payroll taxes associated with equity distributions to employees.
	Several parties have filed appeals seeking reconsideration of the Confirmation Order. See Note 8 to AAG's Consolidated Financial Statements for more information.
	As noted above, the reconciliation process with respect to the remaining claims will take considerable time post-emergence. Included in mandatorily convertible preferred stock and other bankruptcy settlement obligations on the Company's Consolidated Balance Sheet as of December 31, 2013, are the Company's estimates of the amounts of disputed claims that will ultimately become allowed Single-Dip general unsecured claims. As these claims are resolved, or where better information becomes available and is evaluated, we 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 which could potentially limit the ability to utilize certain tax attributes including the Debtors’ substantial NOLs. The general limitation rules for a debtor in a bankruptcy case are liberalized where the ownership change occurs upon emergence from bankruptcy. While the Debtors anticipate taking advantage of certain special rules for federal income tax purposes that would permit approximately $9.0 billion of the federal NOL Carryforwards to be utilized without regard to the annual limitation generally imposed by Section 382, there can be no assurance that these special rules will apply.
	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, the Restated 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 the Restated Certificate of Incorporation was attached as Exhibit 3.1 to a Form 8-K filed on December 9, 2013, by the Company with the Securities and Exchange Commission.
	Liabilities Subject to Compromise
	Liabilities subject to compromise refers to pre-petition obligations which may be impacted by the Chapter 11 reorganization process. These amounts represent the Debtors' current estimate of known or potential pre-petition obligations to be resolved in connection with the Chapter 11 Cases.
	Pursuant to the Plan, allowed pre-petition claims and estimated unresolved pre-petition claims of $5.1 billion were settled in cash, AAG Series A Preferred Stock and other bankruptcy settlement obligations on the Effective Date. The pension and postretirement benefits obligation included below was reinstated and is included in Pension and postretirement benefits in the Company's Consolidated Balance Sheets. Accordingly, there are no Liabilities Subject to Compromise at December 31, 2013.
	The following table summarizes the components of liabilities subject to compromise included on the Consolidated Balance Sheet as of December 31, 2012 (in millions):
	Long-term debt	$	1,198
	Estimated allowed claims on aircraft lease and debt obligations and facility lease and bond obligations	3,716
	Pension and postretirement benefits	1,250
	Accounts payable and other accrued liabilities	442
	Total liabilities subject to compromise	$	6,606
	Long-term debt, including undersecured debt, classified as subject to compromise as of December 31, 2012 consisted of (in millions):
	Secured variable and fixed rate indebtedness due through 2023 (effective rates from 1.00% - 13.00% at December 31, 2012)	$	172
	6.00%—8.50% special facility revenue bonds due through 2036	186
	6.25% senior convertible notes due 2014	460
	9.0%—10.20% debentures due through 2021	214
	7.88%—10.55% notes due through 2039	166
		$	1,198
	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, 2012 and 2011 (in millions):
		2013		2012			2011
	Pension and postretirement benefits	$	—	$	(66	)	$	—
	Labor-related deemed claim	1,733		—			—
	Aircraft and facility financing renegotiations and rejections 1, 2	325		1,950			102
	Fair value of conversion discount 3	218		—			—
	Professional fees	199		229			14
	Other	180		95			2
	Total reorganization items, net	$	2,655	$	2,208		$	118
	-1	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 agreements when the applicable motion was filed with the Bankruptcy Court to reject or modify such financing and the Debtors believed that it was probable the motion would be approved, and there was sufficient information to estimate the claim.
	-2	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 JFK and rejected bonds that financed certain improvements at ORD, which are included in the table above.
	-3	The Plan allows 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.

	Emergence From Chapter 11
	Overview
	On November 29, 2011 (the Petition Date), AMR Corporation (renamed American Airlines Group Inc., AAG, the Company), its principal subsidiary, American Airlines, Inc. (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 the Company, AMR Merger Sub, Inc. (Merger Sub) and US Airways Group, Inc. (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 American Airlines Group common stock (AAG Common Stock), par value $0.01 per share.
	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 Corporation common stock outstanding prior to the Effective Date were canceled. The Restated Certificate of Incorporation, which was approved in connection with the Plan, authorizes the issuance of 1.75 billion new shares of AAG Common Stock, par value $0.01 per share, and 200 million shares of AAG Series A Preferred Stock, par value $0.01 per share. Of the authorized AAG Series A Preferred Stock, approximately 168 million were designated "Series A Convertible Preferred Stock", with a stated value $25.00 per share, and issued in accordance with the Plan. AAG Common Stock and AAG Series A Preferred Stock are listed on the NASDAQ Global Select Market under the symbols "AAL" and "AALCP", respectively, and began trading on December 9, 2013. In addition, pursuant to the Plan, up to 40 million shares of AAG Common Stock was authorized for issuance under the 2013 Incentive Award Plan (the 2013 IAP).
	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 including AMR Corporation and American:
	•	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 are not guaranteed by any other Debtor, other than the claims of the Debtors' labor unions. Holders of Single-Dip Unsecured Claims received, at the Effective Date, a portion of their recovery in shares of AAG Series A Preferred Stock and a right, subject to the trading price of the Company's common stock during the 120 day period after the Effective Date, to receive their remaining recovery in shares of AAG Common Stock 120 days 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 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 (Disputed Claims Reserve), beginning after 120 days after the Effective Date. Disputed claimholders that subsequently become Single-Dip Unsecured Claimholders 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 Single-Dip Unsecured Claimholder as of the Effective Date.
	The Plan contemplates the distribution of up to 756 million shares of common stock of which approximately 53 million shares were issued to the Debtors' stakeholders in connection with the Effective Date. In accordance with the Plan, the Company will issue the remaining shares of AAG Common Stock over the 120 day distribution period and as disputed claims are resolved. In addition, pursuant to the Plan approximately 197 million common shares were distributed to holders of outstanding shares of US Airways Group common stock.
	Pursuant to rulings of the Bankruptcy Court, the Plan has established a disputed claim reserve to hold shares of AAG Series A Preferred Stock and AAG Common Stock reserved for issuance to disputed claimholders that ultimately become allowed Single-Dip general unsecured claimholders after emergence. The shares provided for under the Plan are determined based upon a disputed claim reserve amount of approximately $755 million, representing the maximum amount of additional allowable Single-Dip claims under the Plan's provisions. Approximately 16 million shares of AAG Series A Preferred Stock have been reserved at the Effective Date for distribution to holders of disputed Single-Dip general unsecured claims whose claims ultimately become allowed. Additional new shares of AAG Common Stock will be distributed into the reserve on or about the 120th day after the Effective Date. As disputed claims are resolved, the claimants receive distributions of shares from the 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 the remaining disputed claims, such shares will not be returned to AAG but rather will be distributed by priority first, if necessary, to satisfy unsecured claims or labor-related obligations, and then to former AMR shareholders as of the Effective Date.
	AAG is not required to distribute additional shares above the 756 million shares contemplated by the Plan, even if the shares remaining for distribution are not sufficient to fully pay all allowed unsecured claims. However, resolution of disputed claims could have a material effect on Single-Dip creditor recoveries 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.
	In addition, as of December 31, 2013, American 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 Chapter 11 and interest and penalty interest thereon;
	•	$105 million 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 $300 million for payroll taxes associated with equity distributions to employees
	Several parties have filed appeals seeking reconsideration of the Confirmation Order. See Note 7 to American's Consolidated Financial Statements for more information.
	As noted above, the reconciliation process with respect to the remaining claims will take considerable additional time post emergence. Included in Claim and other bankruptcy settlement obligations on American's Consolidated Balance Sheet as of December 31, 2013, are American's estimates of the amounts of disputed claims that will ultimately become allowed Single-Dip general unsecured claims. As these claims are resolved, or where better information becomes available and is evaluated, AAG will make adjustments to the liabilities recorded in American's Consolidated Financial Statements as appropriate. Any such adjustments could be material to American's financial position or results of operations in any given period.
	Availability and Utilization of Net Operating Losses
	Upon emergence from bankruptcy, the Company experienced an "ownership change" as defined in Section 382 of the Internal Revenue Code which could potentially limit the ability to utilize certain tax attributes including the Company’s substantial NOLs. The general limitation rules for a debtor in a bankruptcy case are liberalized where the ownership change occurs upon emergence from bankruptcy. While the Company anticipates taking advantage of certain special rules for federal income tax purposes that would permit approximately $9.5 billion of the federal NOL Carryforwards to be utilized without regard to the annual limitation generally imposed by Section 382, there can be no assurance that these special rules will apply.
	Moreover, an ownership change subsequent to the Company’s emergence from bankruptcy may further limit or effectively eliminate the ability to utilize the Company’s NOL Carryforwards and other tax attributes. To reduce the risk of a potential adverse effect on the Company’s ability to utilize the NOL Carryforwards, the Restated 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 the Restated Certificate of Incorporation was attached as Exhibit 3.1 to a Form 8-K filed on December 9, 2013 by the Company with the Securities and Exchange Commission.
	Liabilities Subject to Compromise
	Liabilities subject to compromise refers to pre-petition obligations which may be impacted by the Chapter 11 reorganization process. These amounts represent the Debtors' current estimate of known or potential pre-petition obligations to be resolved in connection with the Chapter 11 Cases.
	Pursuant to the Plan, American's allowed pre-petition claims and estimated unresolved pre-petition claims of $4.6 billion were settled in cash, AAG Series A Preferred Stock and other bankruptcy settlement obligations on the Effective Date. The pension and postretirement benefits obligation included below was reinstated and is included in "Pension and postretirement benefits" in American's Consolidated Balance Sheets. Accordingly there are no Liabilities Subject to Compromise at December 31, 2013.
	The following table summarizes the components of liabilities subject to compromise included on the Consolidated Balance Sheet as of December 31, 2012 (in millions):
	Long-term debt	$	358
	Estimated allowed claims on aircraft lease and debt obligations and facility lease and bond obligations	3,716
	Pension and postretirement benefits 1	1,250
	Accounts payable and other accrued liabilities	370
	Other	—
	Total liabilities subject to compromise	$	5,694
	-1	As a result of the modifications to the retirement benefits as discussed in Note 12 to American's Consolidated Financial Statements, a portion of the pension and postretirement benefits liability, primarily relating to retiree medical and other benefits, was classified as liabilities subject to compromise.
	Long-term debt, including undersecured debt, classified as subject to compromise as of December 31, 2012 consisted of (in millions):
	Secured variable and fixed rate indebtedness due through 2023 (effective rates from 1.00% - 13.00% at December 31, 2012)	$	172
	6.00%—8.50% special facility revenue bonds due through 2036	186
		$	358
	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, 2012 and 2011 (in millions):
		2013		2012			2011
	Pension and postretirement benefits	$	—	$	(66	)	$	—
	Labor-related deemed claim	1,733		—			—

	Professional fees	199		227			14
	Other	170		67			—
	Total reorganization items, net	$	2,640	$	2,179		$	116
	-1	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. American recorded an estimated claim associated with the rejection or modification of a financing or facility agreements when the applicable motion was filed with the Bankruptcy Court to reject or modify such financing and the Debtors believed that it was probable the motion would be approved, and there was sufficient information to estimate the claim.
	-2	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 JFK and rejected bonds that financed certain improvements at ORD, which are included in the table above.
	-3	The Plan allows unsecured creditors receiving 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
	As of December 31, 2013, the components of Mandatorily convertible preferred stock and other bankruptcy settlement obligations on the Consolidated Balance Sheet are as follows (in millions):
	AAG Series A Preferred Stock		$	3,833
	Single-dip equity obligations		1,246
	Labor-related deemed claim		849
	Total		$	5,928
	The AAG Series A Preferred Stock, while outstanding, votes and participates in accordance with the terms of the underlying Certificate of Designation. One quarter of the shares of AAG Series A Preferred Stock initially issued is mandatorily convertible on each of the 30th, 60th, 90th and 120th days after the Effective Date. In addition, subject to certain limitations, holders of AAG Series A Preferred Stock may elect to convert up to an additional 10 million shares of AAG Series A Preferred Stock during each 30-day period following the Effective Date thereby reducing the number of shares to be converted on the 120th day after the Effective Date. The initial stated value of each share of AAG Series A Preferred Stock is $25.00 and accrues dividends at 6.25% per annum, calculated daily, while outstanding. Additionally, AAG Series A Preferred Stock converts 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. AAG Series A Preferred Stock embodies an unconditional obligation to transfer a variable number of shares based predominately on a fixed monetary amount known at inception, and, as such, it is not treated as equity, but rather as a liability until such time that it is converted to AAG Common Stock. Accordingly, AAG Series A Preferred Stock outstanding at December 31, 2013 is included within the "Mandatorily convertible preferred stock and other bankruptcy settlement obligations" line on the Company's Consolidated Balance Sheets. Upon conversion of any remaining AAG Series A Preferred Stock on the 120th day after the Effective Date, all AAG Series A Preferred Stock will have been converted to AAG Common Stock and no AAG Series A Preferred Stock will then remain outstanding. As of February 19, 2014, approximately 107 million shares of AAG Series A Preferred Stock had been converted into an aggregate of 95 million shares of AAG Common Stock.
	The Company's Single-Dip equity obligations, while outstanding, do not vote or participate in accordance with the terms of the Plan. These equity contract obligations, representing the amount of total Single-Dip unsecured creditor obligations not satisfied through the issuance of AAG Series A Preferred Stock at the Effective Date, represent an unconditional obligation to transfer a variable number of shares based predominantly on a fixed monetary amount known at inception, and, as such, are not treated as equity, but rather as liabilities until the 120th day after emergence. At the 120th day after emergence, the Company will issue a variable amount of AAG Common Stock necessary to satisfy the obligation amount at emergence, plus accrued dividends of 12% per annum, calculated daily, through the 120th day after emergence, based on the volume weighted average price of the shares of AAG Common Stock at a 3.5% discount, as specified in the Plan and, subject to there being a sufficient number of shares remaining for issuance to unsecured creditors under the Plan.
	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 was approximately $1.7 billion. On the Effective Date, the Company made an initial distribution of $595 million in common stock and American paid approximately $300 million in cash to cover payroll taxes related to the equity distribution. As of December 31, 2013, the remaining liability to certain AMR labor groups and employees of $849 million is based upon the estimated fair value of the shares expected to be issued in satisfaction of such obligation, measured as if the obligation were settled using the trading price of AAG Common Stock at December 31, 2013. Increases in the trading price of AAG Common Stock after December 31, 2013, could cause a decrease in the fair value measurement of the remaining obligation, and vice-versa. The Company will record this obligation at fair value primarily through the 120th day after emergence, at which time the obligation will be materially settled.

Upon the satisfaction of these bankruptcy settlement obligations with AAG Common Stock, the Company will record an increase in additional paid-in capital through an intercompany equity transfer while derecognizing the related bankruptcy settlement obligation at that time.

Merger and Related Matters	'
	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 will not be amortized, but will be tested for impairment at least annually.
	Slot Divestiture
	As a stipulation for the Merger to be approved by the Department of Justice (DOJ), the Company was required to divest certain slots and LaGuardia Airport and Washington Regan National Airport. As of December 31, 2013, the Company recognized a gain of $67 million related to the sale the LaGuardia Airport slots, which has been included in Special items, net in the consolidated statement of operations. The relevant Washington Regan National Airport slots were classified as assets held for sale and included in Prepaid expenses and other on the Consolidated Balance Sheets.
	Tax Matters
	The Company experienced an "ownership change" in connection with its emergence from bankruptcy which under Section 382 could substantially constrain the use of a company’s NOL carryforwards and other tax attributes. However, the general limitation rules of Section 382 are liberalized where the ownership change occurs upon emergence from bankruptcy. While the Company anticipates taking advantage of these special rules that would permit the utilization of substantially all of the company’s NOL carryforwards, there can be no assurance that those special rules will apply. If the special rules do not apply, our ability to utilize our NOL carryforwards may be subject to limitation. See Note 11 for additional information related to tax matters.
	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.

	Allocation of Consideration Transferred
	The Merger has been accounted for using the acquisition method of accounting in accordance with ASC 805, "Business Combinations," 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.

	Frequent flyer liability		(1,256		)
	Other liabilities assumed		(3,143		)
	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. In accordance with ASC 805, the Company may periodically adjust the value of goodwill to reflect changes that occur as a result of adjustments during the measurement period following the date of acquisition.
	Pro-forma Impact of the Merger
	The AAG unaudited pro-forma results presented below include the effects of the US Airways acquisition 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 fair value adjustments, elimination of any deferred gains or losses from other comprehensive income and the impact of income changes on profit sharing expense, among others. However, pro-forma results do not include any anticipated synergies or other expected benefits of the acquisition. 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.

	In accordance with GAAP, the Debtors applied ASC 852 "Reorganizations" (ASC 852), in preparing the Consolidated Financial Statements. ASC 852 requires that the financial statements, for periods subsequent to the Chapter 11 Cases, 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 are recorded in Reorganization Items, Net on the accompanying Consolidated Statement of Operations. In addition, pre-petition obligations that may be impacted by the Chapter 11 reorganization process as of December 31, 2012 were classified on the Consolidated Balance Sheet in Liabilities Subject to Compromise.
	Certain of AMR's non-U.S. subsidiaries were not part of the Chapter 11 Cases. Since these non-US subsidiaries do not have significant transactions, AAG does not separately disclose the combined financial statements of such non-U.S. subsidiaries in accordance with the requirements of reorganization accounting.
	In accordance with ASC 852, AAG did not meet the criteria for and will not adopt "fresh start" accounting as the reorganization value of AMR's assets, as determined based upon an estimate of the fair value of AMR's equity using the trading market price of US Airways Group and the amount of post-petition liabilities as of the Effective Date was greater than total pre-petition liabilities and expected allowed claims. As a result, AAG's assets and liabilities were not adjusted to fair value.
	New Accounting Pronouncements
	Effective January 1, 2013, the Company adopted revised guidance on the Comprehensive Income topic of the FASB Codification which requires an entity to present, either parenthetically on the face of the financial statements or in the notes, significant amounts reclassified from each component of accumulated other comprehensive income (loss) and the income statement line items affected by the reclassification. The adoption did not have any impact on the Company’s financial position, results of operations or cash flows.
	Effective January 1, 2013, the Company adopted revised guidance on Balance Sheet topic of the FASB Codification, which clarifies the scope of disclosures about offsetting assets and liabilities. The clarification applies only to derivatives, repurchase agreements and reverse purchase agreements, and to certain securities borrowing and securities lending transactions, and not to ordinary trade receivables and payables. The adoption did not have any impact on the Company’s financial position, results of operations or cash flows.
	Summary of Significant Accounting Policies
	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States (GAAP) requires management to make estimates and assumptions that affect the amounts reported in the accompanying Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates.
	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, credit card processing holdback requirements.
	Aircraft fuel, spare parts, and supplies, net
	Aircraft fuel, spare parts, and supplies, 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.
	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.
	Goodwill
	Goodwill represents the excess of the purchase price over the net fair value of the assets acquired and liabilities assumed by AAG on December 9, 2013, in connection with the Merger. Goodwill will not be amortized but tested for impairment annually.
	Other Intangibles, net
	Intangible assets consist primarily of airport take-off and landing rights (Slots), customer relationships, market partners, international route authorities, 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.
	In connection with the application of acquisition accounting as of December 9, 2013, the intangible assets acquired from US Airways were measured at fair value using the market and income approaches. The Company utilized the market approach to value airport Slots, when sufficient market information was available, and included prices and other relevant information generated by market transactions involving comparable assets as well as pricing guides and other sources. The Company utilized the income approach to value the customer relationships and marketing agreements, certain international route authorities and the US Airways 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 following table provides information relating to the Company's amortized intangible assets as of December 31, 2013 and 2012 (in millions):
			2013				2012
	Airport Slots		$	332			$	515
	Customer relationships		300				—
	Marketing agreements		105				—
	Tradenames		35				—
	Airport gate leasehold rights		155				155
	Accumulated amortization		(373		)		(509		)
	Total		$	554			$	161
	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 will be amortized over approximately nine years, 30 years and 15 months, respectively.
	The Company recorded amortization expense related to these intangible assets of approximately $20 million, $25 million, and $27 million for the years ended December 31, 2013, 2012 and 2011, respectively. The Company expects to record annual amortization expense for the aforementioned definite-life intangible assets as follows (in millions):
			2014				2015				2016			2017		2018
	Amortization expense		$	79			$	54			$	48		$	44	$	40
	The Company'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, 2013, and 2012, the Company had $1.8 billion and $708 million, respectively, of indefinite-lived intangible assets on its Consolidated Balance Sheet.
	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, 2013, 2012 and 2011 was $47 million, $50 million and $40 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		Shorter 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%, except when guaranteed by a third-party for a different amount.
	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.
	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 statement of operations and recorded as a liability until remitted to the appropriate taxing authority.
	Frequent Flyer Programs
	The Company 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 and oneworld carriers and US Airways and Star Alliance carriers, respectively, as well as certain other partner airlines that participate in the programs. Effective March 31, 2014, US Airways will join the oneworld alliance and exit the Star Alliance. At that point, frequent travel reciprocity will be discontinued for many Star Alliance airlines. Mileage credits can also be earned through purchases from other non-airline partners that participate in our 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 our 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. In addition, the Company also includes in the determination of incremental cost the amount of certain fees related to redemptions expected to be collected from AAdvantage and Dividend Miles members. These redemption fees reduce incremental cost. No profit or overhead margin is included in the accrual of incremental cost. These estimates are generally updated based upon our 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, 2013, the liability for outstanding mileage credits expected to be redeemed for future travel awards for US Airways under the Dividend Miles program was $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, 2013 the liability for outstanding mileage credits for the AAdvantage program was $580 million 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 our adoption of Accounting Standards Update (ASU) No. 2009-13, "Revenue Recognition (Topic 605) - Multiple-Deliverable Revenue Arrangements" on January 1, 2011.
During the fourth quarter, American and Citibank amended their current 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 will apply 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 the fourth quarter 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, 2013 and 2012, the Company had $1.5 billion and $1.2 billion, respectively 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, 2013, 2012 and 2011, the marketing component of mileage sales recognized at the time of sale in other revenues was approximately $834 million, $725 million and $761 million, respectively.
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.
Selling Expenses
Selling expenses include commissions, credit card fees, computerized reservations systems fees and advertising. Advertising expenses are expensed on a straight-line basis as incurred throughout the year. Advertising expense was $166 million, $153 million and $186 million for the years ended December 31, 2013, 2012 and 2011, respectively.
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 and certain vendor incentives.
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 12 for further discussion of share-based compensation.
Foreign Currency Gains and Losses
Foreign currency gains and losses are recorded as part of other nonoperating expense, net in AAG's Consolidated Statements of Operations. Foreign currency losses for 2013, 2012 and 2011 were $56 million, $41 million and $17 million, respectively.
Subsequent Events
In connection with preparation of the Consolidated Financial Statements and in accordance U.S. GAAP, the Company evaluated subsequent events after the balance sheet date of December 31, 2013 and identified items as set forth in Note 20 to AAG's Consolidated Financial Statements.

	Basis of Presentation and Summary of Significant Accounting Policies
	Basis of Presentation
	The Consolidated Financial Statements as of and for the years ended December 31, 2013, 2012 and 2011 include the accounts of American. Certain prior period amounts have been reclassified to conform to the current year financial statement presentation. All significant intercompany transactions have been eliminated.
	Chapter 11 Matters
	In accordance with GAAP, the Debtors applied ASC 852 "Reorganizations" (ASC 852), in preparing the Consolidated Financial Statements. ASC 852 requires that the financial statements, for periods subsequent to the Chapter 11 Cases, 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 are recorded in Reorganization Items, Net on the accompanying Consolidated Statement of Operations. In addition, pre-petition obligations that may be impacted by the Chapter 11 reorganization process as of December 31, 2012 were classified on the Consolidated Balance Sheet in Liabilities Subject to Compromise.
	Certain of American's non-U.S. subsidiaries are not part of the Chapter 11 Cases. Since these non-US subsidiaries do not have significant transactions, American does not separately disclose the combined financial statements of such non-U.S. subsidiaries in accordance with the requirements of reorganization accounting.
	In accordance with ASC 852, American did not meet the criteria for and will not adopt "fresh start" accounting as the reorganization value of American's assets, as determined based upon an estimate of the fair value of AMR's equity using the trading market price of US Airways Group, the amount of post-petition liabilities as of the Effective Date was significantly greater than the total pre-petition liabilities and expected allowed claims. As a result, our assets and liabilities were not adjusted to fair value; but rather liabilities compromised by the Plan are stated at present values of amounts to be paid.
	Reclassifications
	Certain prior period amounts have been reclassified between various financial statement line items to conform to the new AAG financial statement presentation. These reclassifications do not impact the historic net income and are comprised principally of the following items:
	•	Reclassifications between various operating income line items to confirm the presentation of Cargo and Other revenues.
	•	Reclassifications between various operating expense line items to conform the presentation of regional airline expenses.
	•	Reclassifications between other nonoperating income (expense), net and operating expenses to conform the presentation of foreign currency gains and losses.
	The following table summarizes the historical and revised financial statement amounts for American (in millions).

	Additionally, the Company reclassified approximately $292 million from current to noncurrent liabilities as of December 31, 2012.
	New Accounting Pronouncements
	Effective January 1, 2013, American adopted revised guidance on the Comprehensive Income topic of the FASB Codification which requires an entity to present either parenthetically on the face of the financial statements or in the notes, significant amounts reclassified from each component of accumulated other comprehensive income (loss) and the income statement line items affected by the reclassification. The adoption did not have any impact on American’s financial position, results of operations or cash flows.
	Effective January 1, 2013, American adopted revised guidance on Balance Sheet topic of the FASB Codification, which clarifies the scope of disclosures about offsetting assets and liabilities. The clarification applies only to derivatives, repurchase agreements and reverse purchase agreements, and to certain securities borrowing and securities lending transactions, and not to ordinary trade receivables and payables. The adoption did not have any impact on the American’s financial position, results of operations or cash flows.
	Summary of Significant Accounting Policies
	Use of Estimates
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the accompanying Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates.
	Restricted 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
	Aircraft fuel, spare parts, and supplies, 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.
	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.
	Other Intangibles, net
	Intangible assets consist primarily of airport take-off and landing rights (Slots). 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.
	Indefinite-lived intangible assets (route acquisition costs and international Slots) are tested for impairment annually on December 31, rather than amortized, or when a triggering event occurs, in accordance with U.S. GAAP. Such triggering events may include significant changes to the Company's network or capacity, or the implementation of open skies agreements in countries where the Company operates flights.
	As there is minimal market activity for the valuation of routes and international Slots, the Company measures fair value with inputs using the income approach. The income approach uses valuation techniques, such as future cash flows, to convert future amounts to a single present discounted amount. The inputs utilized for these valuations are unobservable and reflect the Company's assumptions about market participants and what they would use to value the routes and accordingly are considered Level 3 in the fair value hierarchy. The Company's unobservable inputs are developed based on the best information available as of December 31, 2013.
	The following table provides information relating to the Company's amortized intangible assets as of December 31, 2013 and 2012 (in millions):
			2013				2012
	Airport Slots		$	277			$	515
	Airport gate leasehold rights		155				155
	Accumulated amortization		(375		)		(509		)
Total		$	57			$	161
Airport operating and gate lease rights are being amortized on a straight-line basis over 25 years to a zero residual value. The Dividend Miles customer relationships, marketing agreements and trademarks were identified as intangible assets subject to amortization and will be amortized over approximately 9 years, 30 years and 15 months, respectively.
American recorded amortization expense related to these intangible assets of approximately $18 million, $25 million, and $27 million for the years ended December 31, 2013, 2012 and 2011, respectively. American expects to record annual amortization expense for the aforementioned definite-life intangible assets as follows (in millions):
		2014				2015				2016			2017		2018
Amortization expense		$	12			$	10			$	9		$	5	$	1
The Company'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, 2013, and 2012, the Company had $755 million and $708 million, respectively, of indefinite-lived intangible assets on its Consolidated Balance Sheet.
Equipment and Property
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, 2013, 2012 and 2011 was $47 million, $50 million and $40 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
American 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		Shorter 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%, except when guaranteed by a third-party for a different amount.
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.
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 the Company's wholly-owned regional air carriers 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. American's wholly-owned regional air carriers 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 statement of operations and recorded as a liability until remitted to the appropriate taxing authority.
Frequent Flyer Programs
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 our frequent flyer liability incurred when AAdvantage members earn mileage credits by flying on American 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, 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. In addition, American also includes in the determination of incremental cost the amount of certain fees related to redemptions expected to be collected from AAdvantage members. These redemption fees reduce incremental cost. No profit or overhead margin is included in the accrual of incremental cost. These estimates are generally updated based upon our 12-month historical average of such costs.
As of December 31, 2013 the liability for outstanding mileage credits for the AAdvantage program was $580 million 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 our adoption of Accounting Standards Update (ASU) No. 2009-13, "Revenue Recognition (Topic 605) - Multiple-Deliverable Revenue Arrangements" on January 1, 2011.
During the fourth quarter, 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 will apply 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 the 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 the fourth quarter 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, 2013 and 2012, 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, 2013, 2012 and 2011, the marketing component of mileage sales recognized at the time of sale in other revenues was approximately $816 million, $725 million and $761 million, respectively.
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.
Selling Expenses
Selling expenses include commissions, credit card fees, computerized reservations systems fees and advertising. Advertising expenses are expensed on a straight-line basis as incurred throughout the year. Advertising expense was $166 million, $153 million and $186 million for the years ended December 31, 2013, 2012 and 2011, respectively.
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 11 for further discussion of share-based compensation.
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 2013, 2012 and 2011 were $55 million, $41 million and $17 million, respectively.
Subsequent Events
In connection with preparation of the Consolidated Financial Statements and in accordance U.S. GAAP, the Company evaluated subsequent events after the balance sheet date of December 31, 2013 and identified items as set forth in Note 17 to American's Consolidated Financial Statements.

	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, 2013, the Company had 508 aircraft under operating leases, with remaining terms ranging from one month to approximately 14 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, 2013, obligations under noncancellable operating leases for future minimum lease payments were as follows (in millions):

	(1) As of December 31, 2013, $322 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 $1.7 billion, $1.4 billion and $1.6 billion in 2013, 2012 and 2011, respectively.
	Sale-leaseback Arrangements
	During 2013, American financed 31 Boeing 737-800 and three 777-300ER aircraft under sale-leaseback arrangements, which are accounted for as operating leases. Gains and losses associated with these sale-leaseback transactions are amortized over the respective remaining lease term and are included in the consolidated balance sheets as deferred gains and prepaid rent, respectively.
	American has entered into sale-leaseback arrangements with certain leasing companies to finance 20 Boeing 737-800 scheduled to be delivered beginning in January 2014. The financings of each aircraft under these arrangements are subject to certain terms and conditions.
	Off-Balance Sheet Arrangements
	Aircraft
	AAG has 185 owned aircraft and 144 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 is 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 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, 2013, $6.0 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. Each lease does have a fair market value or a fixed price purchase option that allows AAG to purchase the aircraft 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, 2013, 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. To the extent these transactions were committed to prior to May 21, 1998, they are accounted for as operating leases. Approximately $498 million of the special facility revenue bonds, with total future payments of approximately $715 million as of December 31, 2013, are guaranteed by AAG, American, US Airways Group or US Airways. Approximately $112 million of these special facility revenue bonds contain mandatory tender provisions that require American to make operating lease payments sufficient to repurchase the bonds in 2014. Although American has the right to remarket the bonds, there can be no assurance that these bonds will be successfully remarketed. Any payments to redeem or purchase bonds that are not remarketed would generally reduce existing rent leveling accruals or are considered prepaid facility rentals and would reduce future operating lease commitments.
	Legal Proceedings
	Chapter 11 Cases. As previously disclosed, on the Petition Date, November 29, 2011, the Debtors filed voluntary petitions for relief under the Bankruptcy Code. On October 21, 2013, the Bankruptcy Court entered the Confirmation Order approving and confirming the Debtors' 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, 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 Bankruptcy Court. However, certain pending litigation related to pre-petition liabilities may proceed in courts other than the Bankruptcy Court to the extent the parties to such litigation have obtained relief from the permanent injunction.
	Pursuant to rulings of the Bankruptcy Court, the Plan has established a disputed claim reserve to hold shares of AAG Series A Preferred Stock and AAG Common Stock reserved for issuance to disputed claimholders that ultimately become allowed Single-Dip general unsecured claimholders after emergence. The shares provided for under the Plan are determined based upon a disputed claim reserve amount of approximately $755 million. As disputed claims are resolved, the claimants receive distributions of shares from the 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 the remaining disputed claims, such shares will not be returned to AAG but rather will be distributed by priority first, if necessary, to satisfy unsecured claims or labor-related obligations, and then to former AMR shareholders as of the Effective Date. AAG is not required to distribute additional shares above the 756 million shares contemplated by the Plan, even if the shares remaining for distribution are not sufficient to fully pay all allowed unsecured claims. However, resolution of disputed claims could have a material effect on Single-Dip creditor recoveries 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 are not vested benefits and thus may be terminated without liability to American. The Bankruptcy Court has not yet ruled on this matter and we cannot predict whether American will receive relief from any of these obligations.
	Government Antitrust Actions. On August 13, 2013, the U.S. government, along with the States of Arizona, Florida, Tennessee and Texas, the Commonwealths of Pennsylvania and Virginia, and the District of Columbia (collectively, the plaintiff states), filed a complaint against US Airways Group and AMR in the U.S. District Court for the District of Columbia. The plaintiffs alleged, among other things, that the proposed Merger would substantially lessen competition in violation of Section 7 of the Clayton Act and sought to permanently enjoin the transaction. On September 5, 2013, the plaintiffs filed an amended complaint, adding the State of Michigan as a plaintiff. On October 1, 2013, the State of Texas entered into an agreement with US Airways Group and AMR that resolved that state’s objections to the Merger, and its claims were dismissed with prejudice on October 7, 2013. On November 11, 2013, US Airways and American entered into agreements with the U.S. government and the plaintiff states resolving all claims in the litigation. The agreement with the U.S. government requires the carriers to divest assets at certain airports and remains subject to public comment and court approval. In the agreement with the United States government, among other things, we agreed to divest and not reacquire for ten years certain rights and assets consisting of 52 Slot pairs at Washington Reagan National Airport, and 17 Slot pairs at LaGuardia, in each case together with and associated gates and related ground facilities necessary to operate those Slot pairs, and two gates at each of Boston Logan International Airport, Chicago O’Hare International Airport, Dallas Love Field, Los Angeles International Airport and Miami International Airport. The agreement with the plaintiff states, which was entered by the court on November 12, 2013, requires our airlines, subject to certain conditions and exceptions, to maintain certain hub operations in a manner generally consistent with historical operations and to continue to provide scheduled daily service to certain specified communities, both for limited periods of time. In addition, we entered into a related settlement with the DOT related to small community service from Washington Reagan National Airport
	Merger Class Action. On March 1, 2013, a complaint captioned Plumbers & Steamfitters Local Union No. 248 Pension Fund v. US Airways Group, Inc., et al., No. CV2013-051605, was filed as a putative class action on behalf of the stockholders of US Airways Group in the Superior Court for Maricopa County, Arizona. On July 3, 2013, an amended complaint, captioned Dennis Palkon, et al. v. US Airways Group, Inc., et al., No. CV2013-051605, was filed with the same court. The amended complaint names as defendants US Airways Group and the members of its board of directors, and alleges that the directors failed to maximize the value of US Airways Group in connection with the Merger and that US Airways Group aided and abetted those breaches of fiduciary duty. The relief sought in the amended complaint includes an injunction against the Merger, or rescission in the event it has been consummated. The court in the above-referenced action denied the plaintiff’s motion for a temporary restraining order that had sought to enjoin the US Airways Group Annual Meeting of Stockholders. The above-referenced action was stayed pending the outcome of the antitrust lawsuit filed by the U.S. government and various states on August 13, 2013 (described above). This stay has now been lifted and a motion to dismiss this action filed by US Airways Group is pending before the court. We believe this lawsuit is without merit and intend to vigorously defend against the allegations.
	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 a claim for money damages and to request injunctive relief requiring the carriers to hold separate their assets. Trial is set for June 2014. We believe this lawsuit is without merit and intend to vigorously defend against the allegations.
	US Airways Sabre Matter. On April 21, 2011, US Airways Inc. filed an antitrust lawsuit against Sabre Holdings Corporation, Sabre Inc. and Sabre Travel International Limited (collectively, Sabre) in 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 our ability to distribute our products to our 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 both injunctive relief and 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. We intend to pursue our 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.
	Guarantees and Indemnifications
US Airways assigned to Delta a lease agreement with the Port Authority of New York and New Jersey related to the East End Terminal at LaGuardia airport. A portion of the rental payments under the lease are used to repay special revenue bonds issued by the Port Authority. The revenue bonds have a final scheduled maturity in 2015 and had an outstanding principal amount of approximately $43 million at December 31, 2013. 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 and derivative transactions, 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.
Venezuela Cash and Short-term Investments
The business environment in Venezuela has been challenging, with economic uncertainty fueled by currency devaluation, high inflation and governmental restrictions, including currency exchange and payment controls, price controls and the possibility of expropriation of property or other resources. As of December 31, 2013, approximately $710 million of our unrestricted cash balance was held as Venezuelan bolivars, valued at a weighted average rate of 6.04 bolivars to the dollar. The period of time to exchange those funds into dollars and repatriate them has been increasing and is presently more than a year. On January 23, 2014, the Venezuelan government issued a regulation to implement a new system for determining the exchange rate based on the result of limited periodic sales of dollars known as Sicad auctions (currently 11.80 to the dollar based on the February 21, 2014 Sicad auction) for repatriation of income from future ticket sales, and introduced new procedures for approval of conversion and repatriation of local currency. The government also enacted a new law effective February 19, 2014 that authorizes additional methods of exchanging Venezuelan bolivars at rates other than the controlled base rate of 6.3 to the dollar or the existing Sicad auction rate, but the regulations necessary to implement the law are still pending and it is not clear at this point whether or how the new methods may impact the pending balances of Venezuelan bolivars held by airlines. We are working with Venezuelan authorities regarding the timing and exchange rate applicable to the repatriation of funds held in local currency. Further, the current, devalued rates may have an ongoing adverse effect on our reported results if we are unable to fully adjust prices on flights to and from Venezuela, of which there can be no assurance. More generally, fluctuations in foreign currencies, including devaluations, cannot be predicted by the Company and can significantly affect the value of our assets located outside the United States. These conditions, as well as any further delays, devaluations or imposition of more stringent repatriation restrictions, may materially adversely affect our business, results of operations and financial condition. 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 additional discussion on currency risks.
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. As of December 31, 2013, American reached an agreement with JAL to settle the liability at an amount already recorded.
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.
As a result of 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, 2013, the remaining liability and the amount of the offsetting receivable were each $1.0 billion.

	In February 2013, American entered into agreements with Boeing that provide for, among other things, the assumption and restructuring of certain existing aircraft purchase agreements, the entering into of a definitive purchase agreement with respect to Boeing 737 MAX aircraft, the confirmation of the purchase of the Boeing 787 aircraft (which previously had been subject to certain reconfirmation rights) and certain financing commitments. American also entered into an amendment to its agreement with Airbus S.A.S. in January 2013.
	In December 2013, American entered into agreements with Bombardier Inc. (Bombardier) and Embraer S.A. (Embraer) under which it plans to acquire 30 Bombardier CRJ900 aircraft to be delivered in 2014 and 2015 and 60 Embraer E175 aircraft to be delivered between 2015 and 2017. The agreement also provides for the option to purchase up to 40 additional CRJ900 aircraft and 90 additional E175 aircraft.
	Facility and support commitments
	American 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):

	Capacity Purchase Agreements with Third-Party Regional Carriers
	As of December 31, 2013, American's capacity purchase agreements with third-party regional carriers had expiration dates ranging from 2014 to 2025, with rights of American to extend the respective terms of each agreement. See Part I, Item 2. Properties for 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, 2013, American's minimum fixed obligations under its capacity purchase agreements with third-party regional carriers were as follows (approximately, in millions):
			2014			2015			2016		2017			2018			2019 and Thereafter		Total

	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, 2013, the Company had 247 aircraft under operating leases, with remaining terms ranging from one month to approximately 14 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, 2013, obligations under noncancellable operating leases for future minimum lease payments were as follows (in millions):
			2014			2015			2016		2017			2018			2019 and Thereafter		Total
	Future minimum lease payments 1		$	1,384		$	1,204		$	1,117	$	1,061		$	982		$	5,302	$	11,050
	(1) As of December 31, 2013, $298 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 $1.6 billion, $1.4 billion and $1.6 billion in 2013, 2012 and 2011, respectively.
	Sale-leaseback Arrangements
	During 2013, American financed 31 Boeing 737-800 and three 777-300ER aircraft under sale-leaseback arrangements, which are accounted for as operating leases. Gains and losses associated with these sale-leaseback transactions are amortized over the respective remaining lease term and are included in the consolidated balance sheets as deferred gains and prepaid rent, respectively.
	American has entered into sale-leaseback arrangements with certain leasing companies to finance 20 Boeing 737-800 scheduled to be delivered beginning in 2014. The financings of each aircraft under these arrangements are subject to certain terms and conditions.
	Off-Balance Sheet Arrangements
	Aircraft
	American has 118 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 is 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, 2013, $3.5 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. Each lease does have a fair market value or a fixed price purchase option that allows American to purchase the aircraft 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, American does not participate in any increases in the value of the aircraft. American concluded it was not the primary beneficiary under these arrangements. Therefore, American accounts for its EETC leveraged lease financings as operating leases. American's has no future obligations under these leveraged lease financing as of December 31, 2013.
	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. To the extent these transactions were committed to prior to May 21, 1998, they are accounted for as operating leases. Approximately $426 million of the special facility revenue bonds are outstanding at December 31, 2013 with total future payments of approximately $619 million as of December 31, 2013. Approximately $112 million of these special facility revenue bonds contain mandatory tender provisions that require American to make operating lease payments sufficient to repurchase the bonds in 2014. Although American has the right to remarket the bonds, there can be no assurance that these bonds will be successfully remarketed. Any payments to redeem or purchase bonds that are not remarketed would generally reduce existing rent leveling accruals or are considered prepaid facility rentals and would reduce future operating lease commitments.
	Legal Proceedings
	Chapter 11 Cases. As previously disclosed, on the Petition Date, November 29, 2011, the Debtors filed voluntary petitions for relief under the Bankruptcy Code. On October 21, 2013, the Bankruptcy Court entered the Confirmation Order approving and confirming the Debtors' 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, 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 Bankruptcy Court. However, certain pending litigation related to pre-petition liabilities may proceed in courts other than the Bankruptcy Court to the extent the parties to such litigation have obtained relief from the permanent injunction.
	Pursuant to rulings of the Bankruptcy Court, the Plan has established a disputed claim reserve to hold shares of AAG Series A Preferred Stock and AAG Common Stock reserved for issuance to disputed claimholders that ultimately become allowed Single-Dip general unsecured claimholders after emergence. The shares provided for under the Plan are determined based upon a disputed claim reserve amount of approximately $755 million. As disputed claims are resolved, the claimants receive distributions of shares from the 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 the remaining disputed claims, such shares will not be returned to AAG but rather will be distributed by priority first, if necessary, to satisfy unsecured claims or labor-related obligations, and then to former AMR shareholders as of the Effective Date. AAG is not required to distribute additional shares above the 756 million shares contemplated by the Plan, even if the shares remaining for distribution are not sufficient to fully pay all allowed unsecured claims. However, resolution of disputed claims could have a material effect on Single-Dip creditor recoveries 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 are not vested benefits and thus may be terminated without liability to American. The Bankruptcy Court has not yet ruled on this matter and we cannot predict whether American will receive relief from any of these obligations.
	Government Antitrust Actions. On August 13, 2013, the U.S. government, along with the States of Arizona, Florida, Tennessee and Texas, the Commonwealths of Pennsylvania and Virginia, and the District of Columbia (collectively, the plaintiff states), filed a complaint against US Airways Group and AMR in the U.S. District Court for the District of Columbia. The plaintiffs alleged, among other things, that the proposed Merger would substantially lessen competition in violation of Section 7 of the Clayton Act and sought to permanently enjoin the transaction. On September 5, 2013, the plaintiffs filed an amended complaint, adding the State of Michigan as a plaintiff. On October 1, 2013, the State of Texas entered into an agreement with US Airways Group and AMR that resolved that state’s objections to the Merger, and its claims were dismissed with prejudice on October 7, 2013. On November 11, 2013, US Airways and American entered into agreements with the U.S. government and the plaintiff states resolving all claims in the litigation. The agreement with the U.S. government requires the carriers to divest assets at certain airports and remains subject to public comment and court approval. In the agreement with the United States government, among other things, we agreed to divest and not reacquire for ten years certain rights and assets consisting of 52 Slot pairs at Washington Reagan National Airport, and 17 Slot pairs at LaGuardia, in each case together with and associated gates and related ground facilities necessary to operate those Slot pairs, and two gates at each of Boston Logan International Airport, Chicago O’Hare International Airport, Dallas Love Field, Los Angeles International Airport and Miami International Airport. The agreement with the plaintiff states, which was entered by the court on November 12, 2013, requires our airlines, subject to certain conditions and exceptions, to maintain certain hub operations in a manner generally consistent with historical operations and to continue to provide scheduled daily service to certain specified communities, both for limited periods of time. In addition, we entered into a related settlement with the DOT related to small community service from Washington Reagan National Airport
	Merger Class Action. On March 1, 2013, a complaint captioned Plumbers & Steamfitters Local Union No. 248 Pension Fund v. US Airways Group, Inc., et al., No. CV2013-051605, was filed as a putative class action on behalf of the stockholders of US Airways Group in the Superior Court for Maricopa County, Arizona. On July 3, 2013, an amended complaint, captioned Dennis Palkon, et al. v. US Airways Group, Inc., et al., No. CV2013-051605, was filed with the same court. The amended complaint names as defendants US Airways Group and the members of its board of directors, and alleges that the directors failed to maximize the value of US Airways Group in connection with the Merger and that US Airways Group aided and abetted those breaches of fiduciary duty. The relief sought in the amended complaint includes an injunction against the Merger, or rescission in the event it has been consummated. The court in the above-referenced action denied the plaintiff’s motion for a temporary restraining order that had sought to enjoin the US Airways Group Annual Meeting of Stockholders. The above-referenced action was stayed pending the outcome of the antitrust lawsuit filed by the U.S. government and various states on August 13, 2013 (described above). This stay has now been lifted and a motion to dismiss this action filed by US Airways Group is pending before the court. We believe this lawsuit is without merit and intend to vigorously defend against the allegations.
	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 a claim for money damages and to request injunctive relief requiring the carriers to hold separate their assets. Trial is set for June 2014. We believe this lawsuit is without merit and intend to vigorously defend against the allegations.
	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.
	Guarantees and Indemnifications
	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, 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 and derivative transactions, 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.
Venezuela Cash and Short-term Investments
The business environment in Venezuela has been challenging, with economic uncertainty fueled by currency devaluation, high inflation and governmental restrictions, including currency exchange and payment controls, price controls and the possibility of expropriation of property or other resources. As of December 31, 2013, approximately $710 million of our unrestricted cash balance was held as Venezuelan bolivars, valued at a weighted average rate of 6.04 bolivars to the dollar. The period of time to exchange those funds into dollars and repatriate them has been increasing and is presently more than a year. On January 23, 2014, the Venezuelan government issued a regulation to implement a new system for determining the exchange rate based on the result of limited periodic sales of dollars known as Sicad auctions (currently 11.80 to the dollar based on the February 21, 2014 Sicad auction) for repatriation of income from future ticket sales, and introduced new procedures for approval of conversion and repatriation of local currency. The government also enacted a new law effective February 19, 2014 that authorizes additional methods of exchanging Venezuelan bolivars at rates other than the controlled base rate of 6.3 to the dollar or the existing Sicad auction rate, but the regulations necessary to implement the law are still pending and it is not clear at this point whether or how the new methods may impact the pending balances of Venezuelan bolivars held by airlines. We are working with Venezuelan authorities regarding the timing and exchange rate applicable to the repatriation of funds held in local currency. Further, the current, devalued rates may have an ongoing adverse effect on our reported results if we are unable to fully adjust prices on flights to and from Venezuela, of which there can be no assurance. More generally, fluctuations in foreign currencies, including devaluations, cannot be predicted by the Company and can significantly affect the value of our assets located outside the United States. These conditions, as well as any further delays, devaluations or imposition of more stringent repatriation restrictions, may materially adversely affect our business, results of operations and financial condition. 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 additional discussion on currency risks.
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. As of December 31, 2013, American reached an agreement with JAL to settle the liability at an amount already recorded.
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.
As a result of 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, 2013, the remaining liability and the amount of the offsetting receivable were each $1.0 billion.

2013-1 EETCs (American)

On March 12, 2013, American closed its private offering of two tranches of enhanced equipment trust certificates (the Series 2013-1A/B EETCs) in the aggregate face amount of $664 million. The Series 2013-1A/B EETCs are comprised of a senior tranche of Class A Certificates with an interest rate of 4.00% per annum and a final expected distribution date of July 15, 2025, and a junior tranche of Class B Certificates with an interest rate of 5.625% per annum and a final expected distribution date of January 15, 2021. The Series 2013-1A/B EETCs represent an interest in the assets of two separate pass through trusts, each of which hold equipment notes issued by American. Interest on the issued and outstanding equipment notes will be payable semiannually on January 15 and July 15 of each year, commencing on July 15, 2013, and principal on such equipment notes is scheduled for payment on January 15 and July 15 of certain years, commencing on January 15, 2014. As of December 31, 2013, the equipment notes are secured by eight currently owned Boeing 737-823 aircraft, one currently owned Boeing 777-223ER aircraft, and four currently owned Boeing 777-323ER aircraft. The certificates were offered in the U.S. to qualified institutional buyers, as defined in, and in reliance on, Rule 144A under the Securities Act of 1933, as amended (the Securities Act).

On June 5, 2013, American closed its private offering of Class C enhanced equipment trust certificates (the Series 2013-1C EETCs) in the aggregate face amount of $120 million. The Series 2013-1C EETCs rank junior to the Series 2013-1A/B EETCs. The Series 2013-1C EETCs were issued with an interest rate of 6.125% per annum and a final expected distribution date of July 15, 2018. The 2013-1C EETCs represent an interest in the assets of a separate pass through trust, which will hold certain equipment notes issued by American. The Series 2013-1C EETCs are secured by the same aircraft securing the Series 2013-1A/B EETCs. The certificates were offered in the U.S. to qualified institutional buyers, as defined in, and in reliance on, Rule 144A under the Securities Act.

2013-2 EETCs (American)

The Company filed a motion with the Bankruptcy Court on October 9, 2012 requesting entry of an order authorizing American to, among other things: (i) obtain post-petition financing in an amount of up to $1.5 billion secured on a first priority basis by, among other things, up to 41 Boeing 737-823 aircraft, 14 Boeing 757-223 aircraft, one Boeing 767-323ER aircraft and 19 Boeing 777-223ER aircraft as part of a new enhanced equipment trust certificate (EETC) financing (the Refinancing EETC) to be offered pursuant to Rule 144A under the Securities Act, and (ii) use cash on hand (including proceeds of the Refinancing EETC) to indefeasibly repay the existing pre-petition obligations secured by such aircraft, as applicable, which are currently financed through, as the case may be, an EETC financing entered into by American in July 2009 (the Series 2009-1 Pass Through Certificates), a secured notes financing entered into by American in July 2009 (the 2009-2 Senior Secured Notes) and an EETC financing entered into by American in October 2011 (the Series 2011-2 Pass Through Certificates and, together with the Series 2009-1 Pass Through Certificates and the 2009-2 Senior Secured Notes, the Existing Financings), in each case without the payment of any make-whole amount or other premium or prepayment penalty.

The Bankruptcy Court approved the motion on January 17, 2013 and entered an order (the EETC Order) to such effect on February 1, 2013. The trustees for the Existing Financings appealed the EETC Order and judgments rendered in certain related adversary proceedings. The appeals (the Appeals) were briefed and oral argument before the United States Court of Appeals for the Second Circuit (the Second Circuit) was heard on June 20, 2013. On September 12, 2013, the Second Circuit fully affirmed the Company's right to repay the Existing Financings without the payment of any make-whole amount or other premium or prepayment penalty. On September 26, 2013, the trustees for the Existing Financings filed a petition for an en banc rehearing of the Appeals by the Second Circuit. On November 18, 2013, the Second Circuit denied such request for rehearing. On February 12, 2014, the trustees for the Existing Financings filed a petition for certiorari to the Supreme Court. American intends to continue to assert vigorously its right to repay the Existing Financings without the payment of any make-whole amounts or other premium or prepayment penalty.

On July 31, 2013, the Company closed its private offering of the Refinancing EETC (the Series 2013-2A EETC) in the aggregate face amount of $1.4 billion with an interest rate of 4.95% per annum and a final expected distribution date of January 15, 2023. In September 2013, American repaid the Existing Financings, including securities tendered to the Company under a tender offer for the Existing Financings that commenced on June 27, 2013, and received the proceeds from the Series 2013-2A EETC. In conjunction with the repayment of the Existing Financings, the Company incurred cash charges of $19 million, included in Interest expense, net of capitalized interest and a charge of $54 million, included in Miscellaneous, net, of which $21 million is cash, related to the premium on tender for the Existing Financings, and $33 million is non-cash, related to the write-off of unamortized issuance costs. The 2013-2A EETC represents an interest in the assets of a separate pass through trust, which will hold certain equipment notes issued by American. The Series 2013-2A EETC is secured by the same aircraft previously used to secure the Existing Financings. The certificates were offered in the U.S. to qualified institutional buyers, as defined in, and in reliance on, Rule 144A under the Securities Act.

On November 27, 2013, American closed its private offering of Class B enhanced equipment trust certificates (the Series 2013-2B EETCs) in the aggregate face amount of $512 million. The Series 2013-2B EETCs rank junior to the Series 2013-2A EETCs. The Series 2013-2B EETCs were issued with an interest rate of 5.60% per annum and a final expected distribution date of July 15, 2020. The 2013-2B EETCs represent an interest in the assets of a separate pass through trust, which will hold certain equipment notes issued by American. The Series 2013-2B EETCs are secured by the same aircraft securing the Series 2013-2A EETCs. The certificates were offered in the U.S. to qualified institutional buyers, as defined in, and in reliance on, Rule 144A under the Securities Act.

On December 20, 2013, American closed its private offering of Class C enhanced equipment trust certificates (the Series 2013-2C EETCs) in the aggregate face amount of $256 million. The Series 2013-2C EETCs generally rank junior to the Series 2013-2A and 2B EETCs. The Series 2013-2C EETCs were issued with an interest rate of 6.00% per annum and a final expected distribution date of January 15, 2017. The 2013-2C EETCs represent an interest in the assets of a separate pass through trust, which will hold certain equipment notes issued by American. The Series 2013-2C EETCs are secured by the same aircraft securing the Series 2013-2A and 2B EETCs. The certificates were offered in the U.S. to qualified institutional buyers, as defined in, and in reliance on, Rule 144A under the Securities Act.

Credit Facilities (American)

On June 27, 2013, American and AAG entered into a Credit and Guaranty Agreement (as amended, the Credit Agreement) with certain lenders. The Credit Agreement provides for a $1.9 billion term loan facility (the Term Loan Facility) and a $1.0 billion revolving credit facility (the Revolving Facility and, together with the Term Loan Facility, the Credit Facilities). As of December 31, 2013, American had borrowed $1.9 billion under the Term Loan Facility. The Credit Facilities are secured obligations of American and guaranteed by AAG. The Revolving Facility provides 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. As of December 31, 2013, there were no borrowings outstanding under the Revolving Facility.

Upon consummation of the Merger, US Airways Group and US Airways joined the Credit Facilities as guarantors. Following the joinder, certain minimum dollar-thresholds under the negative and financial covenants in the Credit Facilities were automatically increased. The Term Loan Facility and Revolving Facility mature on June 27, 2019 and June 27, 2018, respectively, unless otherwise extended by the applicable parties. The 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 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 December 27, 2013. Mandatory prepayments at par of term loans and revolving loans are required to the extent necessary to comply with American's covenants regarding the collateral coverage ratio and certain dispositions of collateral. In addition, if a "change of control" (as defined in the Credit Agreement) occurs, American will, absent an amendment or waiver, be required to repay at par the loans outstanding under the Credit Facilities and terminate the Revolving Facility.

The 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 Term Loan) plus an applicable LIBOR margin. The applicable LIBOR margin is 3.00% for borrowings under both the Term Loan Facility and the Revolving Facility. Subject to certain limitations and exceptions, the Credit Facilities are secured by certain collateral, including liens on certain route authorities to operate between certain specified cities, certain take-off and landing rights at certain airports and American is required to maintain a certain minimum ratio of appraised value of the collateral to the outstanding loans under the Credit Facilities as more fully described below in "Collateral Related Covenants".

The Credit Facilities contain events of default customary for similar financings, including cross-acceleration to other material indebtedness. Upon the occurrence of an event of default, the outstanding obligations under the Credit Facilities may be accelerated and become due and payable immediately. The Credit Facilities also include covenants that, among other things, require AAG and its restricted subsidiaries to maintain a minimum aggregate liquidity (as defined in the Credit Agreement) 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.

Senior Secured Notes (American)

In March 2011, American issued $1.0 billion aggregate principal amount of senior secured notes due 2016 (the Senior Secured Notes) guaranteed on an unsecured basis by AAG. In connection with the closing of the Merger, US Airways and US Airways Group entered into a First Supplemental Indenture, dated as of December 9, 2013, pursuant to which US Airways and US Airways Group became guarantors. The Senior Secured Notes bear interest at a rate of 7.50% per annum, payable semi-annually on March 15 and September 15 of each year, beginning September 15, 2011. As is customary for financings of this nature, the indebtedness evidenced by the Senior Secured Notes may be accelerated upon the occurrence of events of default under the related indenture. Subject to certain limitations and exceptions, the Senior Secured Notes are secured by certain route authorities, airport landing and takeoff slots, and rights to use or occupy space in airport terminals, in each case that American uses to operate non-stop services between certain airports and American is required maintain a certain minimum ratio of appraised value of the collateral to the outstanding amounts under the Senior Secured Notes as more fully described below in "Collateral Related Covenants."

American, at its option, may redeem some or all of the Senior Secured Notes at any time on or after March 15, 2013, at specified redemption prices, plus accrued and unpaid interest, if any. In addition, at any time prior to March 15, 2013, American, at its option, may redeem some or all of the Senior Secured Notes at a redemption price equal to 100% of their principal amount plus a "make-whole" premium and accrued and unpaid interest, if any. In addition, at any time prior to March 15, 2014, American, at its option, may redeem (1) up to 35% of the aggregate principal amount of the Senior Secured Notes with the proceeds of certain equity offerings at a redemption price of 107.5% of their principal amount, plus accrued and unpaid interest, if any, and (2) during any 12-month period, up to 10% of the original aggregate principal amount of the Senior Secured Notes at a redemption price of 103% of their principal amount, plus accrued and unpaid interest, if any. If American sells certain assets or if a "change of control" (as defined in the indenture) occurs, American must offer to repurchase the Senior Secured Notes at prices specified in the indenture.

The indenture for the Senior Secured Notes includes covenants that, among other things, limit the ability of the Company and its subsidiaries to merge, consolidate, sell assets, incur additional indebtedness, issue preferred stock, make investments and pay dividends. The indenture for the Senior Secured Notes also contains events of default customary for similar financings, including cross-default to certain material indebtedness of American. Upon the occurrence of certain events of default, the Senior Secured Notes may be accelerated and become due and payable.

Senior Convertible Notes (AMR Corporation)

On November 29, 2013, the substantially all holders of AMR Corporation's 6.25% senior convertible notes elected to convert their notes into shares of AMR common stock (as an allowed AMR equity interest). Notes for which conversion was not elected prior to the deadline of November 29, 2013 remain in the pool of general unsecured claims to be settled pursuant to the Plan.

Other Financing Transactions (American)

In June 2013, American remarketed approximately $216 million of Tulsa Municipal Airport Revenue Refunding Bonds Trust Series 2000B, 2001A, and 2001B due June 1, 2035 (Series 2000B) and December 1, 2035 (Series 2001 A&B).

Citibank Advanced Purchase Agreement (American)

In 2009, American entered into an arrangement under which Citibank paid to American $1.0 billion in order to pre-purchase AAdvantage Miles (the Pre-Purchase Miles) under American's AAdvantage frequent flier loyalty program (the Pre-Purchase). Approximately $890 million of the Pre-Purchase 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 Pre-Purchase, 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, the Pre-Purchase Miles to Citibank cardholders' AAdvantage accounts.

Pursuant to the Pre-Purchase, Citibank has been granted a first-priority lien on certain of American's AAdvantage program assets. Commencing on December 31, 2011, American has the right to repay in cash, without premium or penalty, any or all of the amounts owed to Citibank that have not already been satisfied by the award of Pre-Purchase Miles to Citibank cardholders' accounts. American is also obligated, in certain circumstances (including certain specified termination events under the Amended Participation Agreement, certain cross defaults and cross acceleration events, and if any Pre-Purchase Miles remain at the end of the term) to repay in cash all outstanding amounts owed Citibank.

The Amended Participation Agreement includes provisions that grant Citibank the right to use Pre-Purchase Miles on an accelerated basis under specified circumstances.

2013 Citicorp Credit Facility (US Airways)

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 by US Airways Group 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 Group’s 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.

The 2013 Citicorp Credit Facility agreement bears interest at an index rate plus an applicable index margin or, at US Airways' option, LIBOR (subject to an original floor of 1.00%) plus an applicable LIBOR margin. As of December 31, 2013, the interest rate was 4.00% based on a 3.00% LIBOR margin for Tranche B-1 and 3.25% based on a 2.25% LIBOR margin for Tranche B-2.

In January 2014, US Airways amended the 2013 Citicorp Credit Facility agreement to lower the applicable LIBOR margin from 3.00% to 2.75% for Tranche B-1. In addition, the LIBOR floor was reduced from 1.00% to 0.75% on both Tranche B-1 and 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 route authorities, 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.

2013-1 EETCs (US Airways)

In April 2013, US Airways created two pass-through trusts which issued approximately $820 million aggregate face amount of Series 2013-1 Class A and Class B EETCs in connection with the financing of 18 Airbus aircraft scheduled to be delivered from September 2013 to June 2014. The 2013-1 EETCs represent fractional undivided interests in the respective pass-through trusts and are not obligations of US Airways. Proceeds received from the sale of EETCs are initially held by a depository in escrow for the benefit of the certificate holders until US Airways issues equipment notes to the trust, which purchases the notes with a portion of the escrowed funds. These escrowed funds are not guaranteed by US Airways and are not reported as debt on US Airways' condensed balance sheet because the proceeds held by the depository are not US Airways' assets.

As of December 31, 2013, $261 million of the escrowed proceeds from the 2013-1 EETCs have been used to purchase equipment notes issued by US Airways in two series: Series A equipment notes in the amount of $198 million bearing interest at 3.95% per annum and Series B equipment notes in the amount of $63 million bearing interest at 5.375% per annum. Interest on the equipment notes is payable semiannually in May and November of each year, and began in November 2013. Principal payments on the equipment notes are scheduled to begin in November 2014. The final payments on the Series A and Series B equipment notes will be due in November 2025 and November 2021, respectively. US Airways' payment obligations under the equipment notes are fully and unconditionally guaranteed by US Airways Group. The net proceeds from the issuance of these equipment notes were used to finance six Airbus aircraft delivered in 2013. The equipment notes are secured by liens on aircraft. The remaining $559 million of escrowed proceeds will be used to purchase equipment notes as new aircraft are delivered.

2012-2 EETCs (US Airways)

The net proceeds from the issuance of the 2012-2 EETCs were used to purchase equipment notes issued by US Airways in three series: Series A equipment notes in the amount of $418 million bearing interest at 4.625% per annum, Series B equipment notes in the amount of $128 million bearing interest at 6.75% per annum and Series C equipment notes in the amount of $100 million bearing interest at 5.45% per annum. Interest on the equipment notes is payable semiannually in June and December of each year and began in June 2013 for Series A and Series B, and December 2013 for Series C. Principal payments on the Series A and Series B equipment notes began in December 2013. The final payments on the Series A equipment notes, Series B equipment notes and Series C equipment notes will be due in June 2025, June 2021 and June 2018, respectively. US Airways' payment obligations under the equipment notes are fully and unconditionally guaranteed by US Airways Group. The only principal payments due on the Series C equipment notes are the principal payments that will be due on the final payment date. The net proceeds from the issuance of these equipment notes were used to finance 11 Airbus aircraft delivered from May 2013 through October 2013. The equipment notes are secured by liens on aircraft.

2012-1 EETCs (US Airways)

In the first quarter of 2013, US Airways issued $183 million of equipment notes in three series under its 2012-1 EETCs completed in May 2012: Series A equipment notes in the amount of $111 million bearing interest at 5.90% per annum, Series B equipment notes in the amount of $37 million bearing interest at 8% per annum and Series C equipment notes in the amount of $35 million bearing interest at 9.125% per annum. The equipment notes are secured by liens on aircraft.

Industrial Development Revenue Bonds (US Airways)

The industrial development revenue bonds are due April 2023. Interest at 6.30% is payable semiannually on April 1 and October 1. The bonds are subject to optional redemption prior to the maturity date, in whole or in part, on any interest payment date at a redemption price of 100%.

6.125% Senior Notes (US Airways)

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.

7.25% Convertible Notes (US Airways)

The 7.25% notes bear interest at a rate of 7.25% per annum, which shall be payable semi-annually in arrears on each May 15 and November 15. The 7.25% notes mature on May 15, 2014.

In connection with the closing of the Merger the 7.25% notes have become convertible into cash, shares of AAG Common Stock or a combination thereof at the Company's election. AAG fully and unconditionally guaranteed all of the payment obligations of US Airways Group under the 7.25% notes.

Holders may convert their 7.25% notes at their option at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date for the 7.25% notes. The initial conversion rate for the 7.25% notes is 218.8184 shares of common stock per $1,000 principal amount of notes (equivalent to an initial conversion price of $4.57 per share). Such conversion rate is subject to adjustment in certain events.

As the 7.25% notes can be settled in cash upon conversion, for accounting purposes, the 7.25% notes were bifurcated into a debt component that was initially recorded at fair value and an equity component. The following table details the debt and equity components recognized related to the 7.25% notes (in millions):

At December 31, 2013, the if-converted value of the 7.25% notes exceeded the principal amount by $101 million.

Collateral Related Covenants

Certain of American's and US Airways’ debt financing agreements contain loan to value ratio covenants and require American and US Airways under their respective financing agreements to periodically appraise the collateral. Pursuant to such agreements, if the loan to value ratio exceeds a specified threshold, American or US Airways is required, as applicable, to subject additional qualifying collateral (which in some cases may include cash collateral), or pay down such financing, in whole or in part, with premium (if any), or pay additional interest on the related indebtedness, as described below.

Specifically, American is required to meet certain collateral coverage tests on a periodic basis on two financing transactions: (1) the Senior Secured Notes and (2) the Credit Facilities, and US Airways is required to meet a collateral coverage test on a periodic basis on the 2013 Citicorp Credit Facility, in each case as described below:

At December 31, 2013, the Company was operating 28 jet aircraft under capital leases. Leases can generally be renewed at rates based on fair market value at the end of the lease term for a number of additional years.

As of December 31, 2013, AAG had issued guarantees covering approximately $1.3 billion of American's tax-exempt bond debt (and interest thereon) and $4.7 billion of American's secured debt (and interest thereon).

In connection with the Merger and pursuant to the Plan on December 9, 2013, (i) American entered into a joinder to loan agreement and became an obligor of US Airways Group's $1.6 billion 2013 Citicorp credit facilities and (ii) American entered into a second supplemental indenture that guaranteed the payment obligations associated with the US Airways Group's 6.125% Notes, due in 2018.

2013-1 EETCs

On March 12, 2013, American closed its private offering of two tranches of enhanced equipment trust certificates (the Series 2013-1A/B EETCs) in the aggregate face amount of $664 million. The Series 2013-1A/B EETCs are comprised of a senior tranche of Class A Certificates with an interest rate of 4.00% per annum and a final expected distribution date of July 15, 2025, and a junior tranche of Class B Certificates with an interest rate of 5.625% per annum and a final expected distribution date of January 15, 2021. The Series 2013-1A/B EETCs represent an interest in the assets of two separate pass through trusts, each of which hold equipment notes issued by American. Interest on the issued and outstanding equipment notes will be payable semiannually on January 15 and July 15 of each year, commencing on July 15, 2013, and principal on such equipment notes is scheduled for payment on January 15 and July 15 of certain years, commencing on January 15, 2014. As of December 31, 2013, the equipment notes are secured by eight currently owned Boeing 737-823 aircraft, one currently owned Boeing 777-223ER aircraft, and four currently owned Boeing 777-323ER aircraft. The certificates were offered in the U.S. to qualified institutional buyers, as defined in, and in reliance on, Rule 144A under the Securities Act of 1933, as amended (the Securities Act).

On June 5, 2013, American closed its private offering of Class C enhanced equipment trust certificates (the Series 2013-1C EETCs) in the aggregate face amount of $120 million. The Series 2013-1C EETCs rank junior to the Series 2013-1A/B EETCs. The Series 2013-1C EETCs were issued with an interest rate of 6.125% per annum and a final expected distribution date of July 15, 2018. The 2013-1C EETCs represent an interest in the assets of a separate pass through trust, which will hold certain equipment notes issued by American. The Series 2013-1C EETCs are secured by the same aircraft securing the Series 2013-1A/B EETCs. The certificates were offered in the U.S. to qualified institutional buyers, as defined in, and in reliance on, Rule 144A under the Securities Act.

2013-2 EETCs

American filed a motion with the Bankruptcy Court on October 9, 2012, requesting entry of an order authorizing American to, among other things: (i) obtain post-petition financing in an amount of up to $1.5 billion secured on a first priority basis by, among other things, up to 41 Boeing 737-823 aircraft, 14 Boeing 757-223 aircraft, one Boeing 767-323ER aircraft and 19 Boeing 777-223ER aircraft as part of a new enhanced equipment trust certificate (EETC) financing (the Refinancing EETC) to be offered pursuant to Rule 144A under the Securities Act, and (ii) use cash on hand (including proceeds of the Refinancing EETC) to indefeasibly repay the existing pre-petition obligations secured by such aircraft, as applicable, which are currently financed through, as the case may be, an EETC financing entered into by American in July 2009 (the Series 2009-1 Pass Through Certificates), a secured notes financing entered into by American in July 2009 (the 2009-2 Senior Secured Notes) and an EETC financing entered into by American in October 2011 (the Series 2011-2 Pass Through Certificates and, together with the Series 2009-1 Pass Through Certificates and the 2009-2 Senior Secured Notes, the Existing Financings), in each case without the payment of any make-whole amount or other premium or prepayment penalty.

The Bankruptcy Court approved the motion on January 17, 2013 and entered an order (the EETC Order) to such effect on February 1, 2013. The trustees for the Existing Financings appealed the EETC Order and judgments rendered in certain related adversary proceedings. The appeals (the Appeals) were briefed and oral argument before the United States Court of Appeals for the Second Circuit (the Second Circuit) was heard on June 20, 2013. On September 12, 2013, the Second Circuit fully affirmed the Company's right to repay the Existing Financings without the payment of any make-whole amount or other premium or prepayment penalty. On September 26, 2013, the trustees for the Existing Financings filed a petition for an en banc rehearing of the Appeals by the Second Circuit. On November 18, 2013, the Second Circuit denied such request for rehearing. On February 12, 2014, the trustees for the Existing Financings filed a petition for certiorari to the Supreme Court. American intends to continue to assert vigorously its right to repay the Existing Financings without the payment of any make-whole amounts or other premium or prepayment penalty.

On July 31, 2013, American closed its private offering of the Refinancing EETC (the Series 2013-2A EETC) in the aggregate face amount of $1.4 billion with an interest rate of 4.95% per annum and a final expected distribution date of January 15, 2023. In September 2013, American repaid the Existing Financings, including securities tendered to the Company under a tender offer for the Existing Financings that commenced on June 27, 2013, and received the proceeds from the Series 2013-2A EETC. In conjunction with the repayment of the Existing Financings, American incurred cash charges of $19 million, included in Interest expense, net of capitalized interest and a charge of $54 million, included in Miscellaneous, net, of which $21 million is cash, related to the premium on tender for the Existing Financings, and $33 million is non-cash, related to the write-off of unamortized issuance costs. The 2013-2A EETC represents an interest in the assets of a separate pass through trust, which will hold certain equipment notes issued by American. The Series 2013-2A EETC is secured by the same aircraft previously used to secure the Existing Financings. The certificates were offered in the U.S. to qualified institutional buyers, as defined in, and in reliance on, Rule 144A under the Securities Act.

On November 27, 2013, American closed its private offering of Class B enhanced equipment trust certificates (the Series 2013-2B EETCs) in the aggregate face amount of $512 million. The Series 2013-2B EETCs rank junior to the Series 2013-2A EETCs. The Series 2013-2B EETCs were issued with an interest rate of 5.60% per annum and a final expected distribution date of July 15, 2020. The 2013-2C EETCs represent an interest in the assets of a separate pass through trust, which will hold certain equipment notes issued by American. The Series 2013-2B EETCs are secured by the same aircraft securing the Series 2013-2A EETCs. The certificates were offered in the U.S. to qualified institutional buyers, as defined in, and in reliance on, Rule 144A under the Securities Act.

On December 20, 2013, American closed its private offering of Class C enhanced equipment trust certificates (the Series 2013-2C EETCs) in the aggregate face amount of $256 million. The Series 2013-2C EETCs generally rank junior to the Series 2013-2A and 2B EETCs. The Series 2013-2C EETCs were issued with an interest rate of 6.00% per annum and a final expected distribution date of January 15, 2017. The 2013-2C EETCs represent an interest in the assets of a separate pass through trust, which will hold certain equipment notes issued by American. The Series 2013-2C EETCs are secured by the same aircraft securing the Series 2013-2A and 2B EETCs. The certificates were offered in the U.S. to qualified institutional buyers, as defined in, and in reliance on, Rule 144A under the Securities Act.

Credit Facilities

On June 27, 2013, American and AAG entered into a Credit and Guaranty Agreement (as amended, the Credit Agreement) with certain lenders. The Credit Agreement provides for a $1.9 billion term loan facility (the Term Loan Facility) and a $1.0 billion revolving credit facility (the Revolving Facility and, together with the Term Loan Facility, the Credit Facilities). As of December 31, 2013, American had borrowed $1.9 billion under the Term Loan Facility. The Credit Facilities are secured obligations of American and guaranteed by AAG. The Revolving Facility provides 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. As of December 31, 2013, there were no borrowings outstanding under the Revolving Facility.

Upon consummation of the Merger, US Airways Group and US Airways joined the Credit Facilities as guarantors. Following the joinder, certain minimum dollar-thresholds under the negative and financial covenants in the Credit Facilities were automatically increased. The Term Loan Facility and Revolving Facility mature on June 27, 2019 and June 27, 2018, respectively, unless otherwise extended by the applicable parties. The 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 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 December 27, 2013. Mandatory prepayments at par of term loans and revolving loans are required to the extent necessary to comply with American's covenants regarding the collateral coverage ratio and certain dispositions of collateral. In addition, if a "change of control" (as defined in the Credit Agreement) occurs, American will, absent an amendment or waiver, be required to repay at par the loans outstanding under the Credit Facilities and terminate the Revolving Facility.

The 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 Term Loan) plus an applicable LIBOR margin. The applicable LIBOR margin is 3.00% for borrowings under both the Term Loan Facility and the Revolving Facility. Subject to certain limitations and exceptions, the Credit Facilities are secured by certain collateral, including liens on certain route authorities to operate between certain specified cities, certain take-off and landing rights at certain airports and American is required to maintain a certain minimum ratio of appraised value of the collateral to the outstanding loans under the Credit Facilities as more fully described below in "Collateral Related Covenants".

The Credit Facilities contain events of default customary for similar financings, including cross-acceleration to other material indebtedness. Upon the occurrence of an event of default, the outstanding obligations under the Credit Facilities may be accelerated and become due and payable immediately. The Credit Facilities also include affirmative, negative, and financial covenants that, among other things, require AAG and its restricted subsidiaries to maintain a minimum aggregate liquidity (as defined in the Credit Agreement) of not less than $2.0 billion and limit the ability of AAG and its restricted subsidiaries, including American, 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.

Senior Secured Notes

In March 2011, American issued $1.0 billion aggregate principal amount of senior secured notes due 2016 (the Senior Secured Notes) guaranteed on an unsecured basis by AAG. In connection with the closing of the Merger, US Airways and US Airways Group entered into a First Supplemental Indenture, dated as of December 9, 2013, pursuant to which US Airways and US Airways Group became guarantors. The Senior Secured Notes bear interest at a rate of 7.50% per annum, payable semi-annually on March 15 and September 15 of each year, beginning September 15, 2011. As is customary for financings of this nature, the indebtedness evidenced by the Senior Secured Notes may be accelerated upon the occurrence of events of default under the related indenture. Subject to certain limitations and exceptions, the Senior Secured Notes are secured by certain route authorities, airport landing and takeoff slots, and rights to use or occupy space in airport terminals, in each case that American uses to operate non-stop services between certain airports and American is required maintain a certain minimum ratio of appraised value of the collateral to the outstanding amounts under the Senior Secured Notes as more fully described above in "Collateral Related Covenants."

American, at its option, may redeem some or all of the Senior Secured Notes at any time on or after March 15, 2013, at specified redemption prices, plus accrued and unpaid interest, if any. In addition, at any time prior to March 15, 2013, American, at its option, may redeem some or all of the Senior Secured Notes at a redemption price equal to 100% of their principal amount plus a "make-whole" premium and accrued and unpaid interest, if any. In addition, at any time prior to March 15, 2014, American, at its option, may redeem (1) up to 35% of the aggregate principal amount of the Senior Secured Notes with the proceeds of certain equity offerings at a redemption price of 107.5% of their principal amount, plus accrued and unpaid interest, if any, and (2) during any 12-month period, up to 10% of the original aggregate principal amount of the Senior Secured Notes at a redemption price of 103% of their principal amount, plus accrued and unpaid interest, if any. If American sells certain assets or if a "change of control" (as defined in the indenture) occurs, American must offer to repurchase the Senior Secured Notes at prices specified in the indenture.

The indenture for the Senior Secured Notes includes covenants that, among other things, limit the ability of the Company and its subsidiaries to merge, consolidate, sell assets, incur additional indebtedness, issue preferred stock, make investments and pay dividends. The indenture for the Senior Secured Notes also contains events of default customary for similar financings, including cross-default to certain material indebtedness of American. Upon the occurrence of certain events of default, the Senior Secured Notes may be accelerated and become due and payable.

Other Financing Transactions

In June 2013, American also remarketed approximately $216 million of Tulsa Municipal Airport Revenue Refunding Bonds Trust Series 2000B, 2001A, and 2001B due June 1, 2035 (Series 2000B) and December 1, 2035 (Series 2001 A&B).

Citibank Advanced Purchase Agreement

In 2009, American entered into an arrangement under which Citibank paid to American $1.0 billion in order to pre-purchase AAdvantage Miles (the Pre-Purchase Miles) under American's AAdvantage frequent flier loyalty program (the Pre-Purchase). Approximately $890 million of the Pre-Purchase 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 Pre-Purchase, 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, the Pre-Purchase Miles to Citibank cardholders' AAdvantage accounts.

Pursuant to the Pre-Purchase, Citibank has been granted a first-priority lien on certain of American's AAdvantage program assets. Commencing on December 31, 2011, American has the right to repay in cash, without premium or penalty, any or all of the amounts owed to Citibank that have not already been satisfied by the award of Pre-Purchase Miles to Citibank cardholders' accounts. American is also obligated, in certain circumstances (including certain specified termination events under the Amended Participation Agreement, certain cross defaults and cross acceleration events, and if any Pre-Purchase Miles remain at the end of the term) to repay in cash all outstanding amounts owed Citibank.

The Amended Participation Agreement includes provisions that grant Citibank the right to use Pre-Purchase Miles on an accelerated basis under specified circumstances.

Collateral Related Covenants

Certain of American's debt financing agreements contain loan to value ratio covenants and require American to periodically appraise the collateral. Pursuant to such agreements, if the loan to value ratio exceeds a specified threshold, American is required, as applicable, to subject additional qualifying collateral (which in some cases may include cash collateral), or pay down such financing, in whole or in part, with premium (if any), or pay additional interest on the related indebtedness, as described below.

Specifically, American is required to meet certain collateral coverage tests on a periodic basis on two financing transactions: (1) the Senior Secured Notes and (2) Credit Facilities, as described below:

	As of December 31, 2013, American had fuel derivative contracts outstanding covering 22 million barrels of jet fuel that will be settled over the next eighteen months. The Company does not hold or issue derivative financial instruments for trading purposes. The Company has not entered into any fuel hedges since the Effective Date and its current policy is not to do so.
	In accordance with U.S. GAAP, the Company assesses, both at the inception of each hedge and on an ongoing basis, whether the derivatives that are used in its hedging transactions are highly effective in offsetting changes in cash flows of the hedged items. Derivatives that meet the requirements are granted special hedge accounting treatment, and the Company’s hedges generally meet these requirements. Accordingly, the Company’s fuel derivative contracts are accounted for as cash flow hedges, and the fair value of the Company’s hedging contracts is recorded in Current Assets or Current Liabilities in the accompanying Consolidated Balance Sheets until the underlying jet fuel is purchased. The Company determines the ineffective portion of its fuel hedge contracts by comparing the cumulative change in the total value of the fuel hedge contract, or group of fuel hedge contracts, to the cumulative change in a hypothetical jet fuel hedge. If the total cumulative change in value of the fuel hedge contract more than offsets the total cumulative change in a hypothetical jet fuel hedge, the difference is considered ineffective and is immediately recognized as a component of Aircraft fuel expense. Effective gains or losses on fuel hedging contracts are deferred in Accumulated other comprehensive income (loss) and are recognized in earnings as a component of Aircraft fuel expense when the underlying jet fuel being hedged is used.
	Ineffectiveness is inherent in hedging jet fuel with derivative positions based in crude oil or other crude oil related commodities. The Company assesses, both at the inception of each hedge and on an ongoing basis, whether the derivatives that are used in its hedging transactions are highly effective in offsetting changes in cash flows of the hedged items. In doing so, the Company uses a regression model to determine the correlation of the change in prices of the commodities used to hedge jet fuel (e.g., NYMEX Heating oil) to the change in the price of jet fuel. The Company also monitors the actual dollar offset of the hedges’ market values as compared to hypothetical jet fuel hedges. The fuel hedge contracts are generally deemed to be "highly effective" if the R-squared is greater than 80% and the dollar offset correlation is within 80% to 125%. The Company discontinues hedge accounting prospectively if it determines that a derivative is no longer expected to be highly effective as a hedge or if it decides to discontinue the hedging relationship. Subsequently, any changes in the fair value of these derivatives are marked to market through earnings in the period of change.
	For the years ended December 31, 2013, 2012 and 2011, American recognized net gains/(losses) of approximately $(12) million, $4 million and $341 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 net fair value of the Company’s fuel hedging agreements at December 31, 2013 and 2012, representing the amount American would receive upon termination of the agreements (net of settled contract assets), totaled $107 million and $62 million, respectively. As of December 31, 2013, American estimates that during the next twelve months it will reclassify from Accumulated other comprehensive income (loss) into earnings approximately $45 million in net gains (based on prices as of December 31, 2013) related to its fuel derivative hedges.

	While certain of the Company's fuel derivatives are subject to enforceable master netting agreements with its counterparties, the Company does not offset its fuel derivative assets and liabilities in its Consolidated Balance Sheets.

	The Company is also exposed to credit losses in the event of non-performance by counterparties to these financial instruments, and although no assurances can be given, the Company does not expect any of the counterparties to fail to meet their obligations. The credit exposure related to these financial instruments is represented by the fair value of contracts with a positive fair value at the reporting date, reduced by the effects of master netting agreements. To manage credit risks, the Company selects counterparties based on credit ratings, limits its exposure to a single counterparty under defined guidelines, and monitors the market position of the program and its relative market position with each counterparty. The Company also maintains industry-standard security agreements with a number of its counterparties which may require the Company or the counterparty to post collateral if the value of selected instruments exceeds specified mark-to-market thresholds or upon certain changes in credit ratings. The amount of collateral required to be posted from time to time may be substantial.

	The merger of US Airways into American Airlines Group Inc. closed on December 9, 2013. For the period beginning on December 9, 2013 and ending on December 31, 2013, US Airways Group, Inc. and its subsidiaries are now included in the AAG consolidated federal and state income tax returns.
	The Company recorded a net income tax benefit of $346 million which is composed of a $538 million non-cash income tax benefit, a $214 million tax charge for additional valuation allowance, and $22 million income tax credit. The Company recorded a $538 million non-cash income tax benefit from continuing operations during the fourth quarter of 2013. Under current accounting rules, 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 is 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, 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 for this item, the Company's year-end net deferred tax position is not impacted by this tax allocation. The Company recorded similar amounts when reporting other comprehensive income in 2009 and 2012. The resulting residual income tax expense will remain in Accumulated other comprehensive income (loss) (AOCI) until all amounts in AOCI that relate to the plan or program that gave rise to the residual income taxes are recognized in the Consolidated Statement of Operations. The Company will reclassify to earnings all residual tax amounts relating to our Pension and Retiree Medical Liability (specifically relating to Pension and OPEB activity) and Derivative Financial Instruments (specifically relating to Fuel Hedging Contracts activity) in the period in which there are no longer any amounts in AOCI associated with those plans or programs. The Company anticipates recognizing a non-cash income tax expense of $313 million in continuing operations during 2015 upon the settlement of the currently outstanding Fuel Hedging Contract arrangements.
	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. In assessing the realizability of the deferred tax assets, management considers whether it is more likely than not that some portion, or all of the deferred tax assets, will 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. The assessment of realization of deferred tax assets considers those tax planning strategies that management believes to be prudent and feasible strategies the Company would implement, if necessary, to prevent a tax attribute from expiring. During the fourth quarter of 2013, the Company recorded 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. US Airways, Group Inc is required under ASC 805, as a result of its merger, to use purchase accounting to establish the fair values of its assets and liabilities. The resulting tax accounting establishes a federal deferred tax liability for its indefinite-lived assets in the amount of $306 million which has been accounted for through goodwill.
	A portion of the change in the valuation allowance reflects the recording by the Company in 2013, 2012 and 2011 of an income tax expense (credit) of approximately $(22) million, $0 million and $(25) million, respectively, 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 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 increase in the valuation allowance was $602 million, $263 million, and $1.2 billion in 2013, 2012 and 2011, respectively.

	At December 31, 2013, the Company had available for federal income tax purposes an AMT credit carryforward of approximately $370 million, which is available for an indefinite period, and federal net operating losses of approximately $10.6 billion for regular tax purposes, which will expire, if unused, beginning in 2022. These net operating losses include an unrealized benefit of approximately $762 million related to the implementation of share-based compensation accounting guidance that will be recorded in equity when realized. The Company had available for state income tax purposes net operating losses of $4.7 billion, which expire, if unused, in years 2014 through 2033. The amount that will expire in 2014 is $106 million if not used.
	We experienced a statutory "ownership change" on December 9, 2013 as defined for purposes of Section 382 of the Internal Revenue Code in connection with our emergence from bankruptcy and US Airways Group experienced an ownership change in connection with the Merger. When a company undergoes such an ownership change, Section 382 limits the company’s future ability to utilize any NOL generated before the ownership change and certain subsequently recognized "built-in" losses and deductions, if any, existing as of the date of the ownership change. The general limitation rules for a debtor in a bankruptcy case are liberalized where an ownership change occurs upon emergence from bankruptcy. We anticipate taking advantage of these certain special rules which will permit approximately $9.0 billion of our federal NOL carryforwards to be utilized without regard to the annual limitation generally imposed by Section 382. At December 31, 2013, the Company inherited the US Airways Group approximate $1.6 billion of NOLs ($1.4 billion of which is subject to Section 382 limitation due to the ownership change) to reduce the Company’s future taxable income. The majority of American Airlines Group Inc.’s NOLs are expected to be available to reduce federal taxable income in the calendar year 2014. The Company’s ability to utilize any new NOL arising after the ownership change is not affected.
	The Company files its tax returns as prescribed by the tax laws of the jurisdictions in which it operates. The Company’s 2004 through 2012 tax years are still subject to examination by the Internal Revenue Service. Various state and foreign jurisdiction tax years remain open to examination and the Company is under examination, in administrative appeals, or engaged in tax litigation in certain jurisdictions. The Company believes that the effect of any additional assessment(s) will be immaterial to its Consolidated Financial Statements.
	Cash payments for income taxes were $12 million, $6 million and $1 million for 2013, 2012 and 2011, respectively.
	Under special tax rules (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 net operating losses (NOL) carryforwards may be limited."
	The Company has an unrecognized tax benefit of approximately $6 million, which did not change during the twelve months ended December 31, 2013. 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, 2013.

	American recorded a net income tax benefit of $354 million which is composed of a $538 million non-cash income tax benefit, a $214 million tax charge for additional valuation allowance, and a $30 million income tax credit. American recorded a $538 million non-cash income tax benefit from continuing operations during the fourth quarter of 2013. Under current accounting rules, 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 will be 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, 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 for this item, American's year-end net deferred tax position is not impacted by this tax allocation. American recorded similar amounts when reporting other comprehensive income in 2009 and 2012. The resulting residual income tax expense will remain in Accumulated other comprehensive income (AOCI) until all amounts in AOCI that relate to the plan or program that gave rise to the residual income taxes are recognized in the Consolidated Statement of Operations. American will reclassify to earnings all residual tax amounts relating to our Pension and Retiree Medical Liability (specifically relating to Pension and OPEB activity) and Derivative Financial Instruments (specifically relating to Fuel Hedging Contracts activity) in the period in which there are no longer any amounts in AOCI associated with those plans or programs. American anticipates recognizing a non-cash income tax expense of $313 million in continuing operations during 2015 upon the settlement of the currently outstanding Fuel Hedging Contract arrangements.
	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. In assessing the realizability of the deferred tax assets, management considers whether it is more likely than not that some portion, or all of the deferred tax assets, will 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. The assessment of realization of deferred tax assets considers those tax planning strategies that management believes to be prudent and feasible strategies American would implement, if necessary, to prevent a tax attribute from expiring. During the fourth quarter of 2013, American recorded 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 portion of change in the valuation allowance reflects the recording by American in 2013, 2012 and 2011 of an income tax expense (credit) of approximately $(30) million, $0 million and $(25) million, respectively, 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 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 13 to American's Consolidated Financial Statements. The total increase in the valuation allowance was $155 million, $282 million, and $1.1 billion in 2013, 2012 and 2011, respectively.

	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 2011 Plan and shall only be made to individuals who were not providing services to AAG prior to the Merger. Award 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, Alignment and Equity Incentive, 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.
	In 2013, share-based compensation expense of $42 million, related to the Merger, was recorded under Special items, net and $50 million was recorded under Salaries, wages and benefits. In 2012 and 2011 the total charge for share-based compensation expense, included in Salaries, wages, and benefits expense, was $29 million and $40 million, respectively.
	Restricted Stock Unit (RSU) Awards
	As of December 31, 2013, 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.
	Alignment Awards
	On December 9, 2013, alignment awards were granted in the form of RSUs and are expected to be settled in AAG Common Stock subject to potential NOL restrictions. The awards were provided to legacy AMR employees in order to align interests and create parity with peers at US Airways 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 recorded in connection with these awards have been and will be charged to Merger related expenses.

	US Airways Stock Options and Stock Appreciation Rights
	Stock options and stock appreciation rights are granted with an exercise price equal to the underlying common stock’s fair value at the date of each grant. 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. Cash-settled stock appreciation rights (CSARs) are classified as liability awards as the exercise results in payment of cash by the Company.

The fair value of stock options and stock appreciation rights is determined at the grant date using a Black-Scholes option pricing model, which requires several assumptions. The risk-free interest rate is based on the U.S. Treasury yield curve in effect for the expected term of the award at the time of grant. The dividend yield is assumed to be zero as the Company does not pay dividends. The volatility is based on the historical volatility of the Company’s common stock over a time period equal to the expected term of the award. The expected term of the award is based on the historical experience of the Company. Stock options and stock appreciation rights are expensed on a straight-line basis over the vesting period for the entire award. There were no stock options or stock appreciation rights granted subsequent to the Merger closing date.
As of December 31, 2013, there were $22 million of total unrecognized compensation costs related to SARs. These costs are expected to be recognized over a weighted average period of 0.7 years. The total intrinsic value of stock options and SARs exercised during the 23 day period ending December 31, 2013 was $0.5 million.
As of December 31, 2013, the weighted average fair value of outstanding CSARs was $19.11 per share and the related liability was $52 million. These CSARs will continue to be remeasured at fair value at each reporting date until all awards are settled. As of December 31, 2013, the total unrecognized compensation expense for CSARs was $2 million and is expected to be recognized over a weighted average period of 0.3 years. Total cash paid for CSARs exercised during the during the 23 day period ending December 31, 2013 was $0.5 million.
AMR Incentive Awards
Prior to the Petition Date, AMR adopted certain plans which provided for the issuance of common stock in connection with the exercise of stock options and other share-based awards. AMR granted stock compensation under three plans: the 1998 Long Term Incentive Plan (the 1998 Plan), the 2003 Employee Stock Incentive Plan (the 2003 Plan) and the 2009 Long Term Incentive Plan (the 2009 Plan). Collectively, the 1998 Plan and the 2009 Plan are referred to as the LTIP Plans. No awards were made under AMR's plans in 2012 or 2013. AMR had share-based incentive awards including stock options/stock appreciation rights granted under the LTIP Plans and the 2003 Plan, performance share awards granted under the LTIP plans and based upon a requisite service period and contingently issuable based upon the AMR's relative stock price performance compared to certain of its competitors over a three year period, deferred share awards granted under the LTIP plans and based solely on a requisite service period and career equity awards granted to certain employees of AMR vesting upon the retirement of those individuals. Deferred share and career equity awards totaling 5,899,500 shares vested in AMR common stock pursuant to the Plan. These plan participants become holders of interest in AMR Corporation and will receive distributions of AAG common stock in accordance with the Plan (See Note 2 to AAG's Consolidated Financial Statements for information regarding the Plan). All remaining outstanding awards were canceled in accordance with the Plan upon emergence from Chapter 11.
Activity of all previous AMR awards is as follows:

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 2011 Plan and shall only be made to individuals who were not providing services to AAG prior to the Merger. Award 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, Alignment and Equity Incentive, related to the Merger and future service. Awards issued in conjunction with the Plan are discussed in more detail below.
	In 2013, share-based compensation expense of $37 million, related to the Merger, was recorded under Special items, net and $28 million was recorded under Salaries, wages and benefits. In 2012 and 2011 the total charge for share-based compensation expense, included in Salaries, wages, and benefits expense, was $26 million and $35 million, respectively.
	Restricted Stock Unit (RSU) Awards
	As of December 31, 2013, American 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.

	Prior to the Petition Date, American adopted certain plans which provided for the issuance of common stock in connection with the exercise of stock options and other share-based awards. American granted stock compensation under three plans: the 1998 Long Term Incentive Plan (the 1998 Plan), the 2003 Employee Stock Incentive Plan (the 2003 Plan) and the 2009 Long Term Incentive Plan (the 2009 Plan). Collectively, the 1998 Plan and the 2009 Plan are referred to as the LTIP Plans. No awards were made under American's plans in 2012 or 2013. American had share-based incentive awards including stock options/stock appreciation rights granted under the LTIP Plans and the 2003 Plan, performance share awards granted under the LTIP plans and based upon a requisite service period and contingently issuable based upon the AMR's relative stock price performance compared to certain of its competitors over a three year period, deferred share awards granted under the LTIP plans and based solely on a requisite service period and career equity awards granted to certain employees of the Company vesting upon the retirement of those individuals. Deferred share and career equity awards totaling 5,899,500 shares vested in AMR common stock pursuant to the Plan. These plan participants become holders of interest in AMR Corporation and will receive distributions of AAG common stock in accordance with the Plan (See Note 2 to American's Consolidated Financial Statements for information regarding the Plan). All remaining outstanding awards were canceled in accordance with the Plan upon emergence from Chapter 11.

	Retirement Benefits
	The Company 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. The Company uses a December 31 measurement date for all of its defined benefit plans. In addition, the Company provides certain postemployment benefits to its employees. These benefits include disability-related and workers' compensation benefits for certain employees. The Company accrues for the cost of such benefit expenses once an appropriate triggering event has occurred.

Expected return on plan assets		8	%		8.25	%		8	%		8.25	%
As of December 31, 2013, 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, 2013, was approximately 8.93%.
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 period.

The Company is required to make minimum contributions to its defined benefit pension plans under the minimum funding requirements of 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 2013 the Company contributed $489 million to its defined benefit pension plans, which covered minimum contributions for periods prior to the Company’s Chapter 11 filing and periods thereafter (see Note 2 to AAG's Consolidated Financial Statements for further information), as well as certain interest and penalty interest due with respect to contributions for pre-petition periods. On January 15, 2014, the Company contributed an additional $34 million to its defined benefit pension plans representing the final quarterly contribution for the 2013 plan year.
The Company's minimum required contribution to its pension plans for 2014 is $120 million. 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 eligible employees began to receive a replacement benefit under the $uper $aver 401(k) Plan. The Company matches employee contributions up to 5.5% of eligible earnings and, with the ratification of a new CBA by pilots on December 7, 2012, pilots receive contributions of 14% under the same plan.
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 is appealing the Bankruptcy Court's decisions authorizing American to reject the pilot CBA and approve the new pilot CBA. All of these appeals have been consolidated, and are pending in the U.S. District Court for the Southern District of New York.
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, we expect all remaining funds, which represent a small group of uncashed distribution checks, to be distributed by the end of second quarter 2014.
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 Court held a hearing on January 23, 2013 and has not ruled on this matter as of the date of this report. The Company has been negotiating with the retiree committee since July 2012, seeking a consensual agreement to terminate subsidized retiree medical coverage and life insurance coverage.
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. See Note 2 to AAG's Consolidated Financial Statements for the breakout of liabilities subject to compromise, including that related to pension and postretirement benefits.
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
	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.

As of December 31, 2013, 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, 2013, was approximately 8.93%.
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, 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. 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 period.

American is required to make minimum contributions to its defined benefit pension plans under the minimum funding requirements of 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 2013 American contributed $489 million to its defined benefit pension plans, which covered minimum contributions for periods prior to the American’s Chapter 11 filing and periods thereafter (see Note 2 to American's Consolidated Financial Statements for further information), as well as certain interest and penalty interest due with respect to contributions for pre-petition periods. On January 15, 2014, American contributed an additional $34 million to its defined benefit pension plans representing the final quarterly contribution for the 2013 plan year.
American's minimum required contribution to its pension plans for 2014 is $120 million. 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.

Modifications to Retirement and Life Insurance Benefits
Effective November 1, 2012, American's defined benefit pension plans were frozen and eligible employees began to receive a replacement benefit under the $uper $aver 401(k) Plan. American matches employee contributions up to 5.5% of eligible earnings and, with the ratification of a new CBA by pilots on December 7, 2012, pilots receive contributions of 14% under the same plan.
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 is appealing the Bankruptcy Court's decisions authorizing American to reject the pilot CBA and approve the new pilot CBA. All of these appeals have been consolidated, and are pending in the U.S. District Court for the Southern District of New York.
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 expects all remaining funds, which represent a small group of uncashed distribution checks, to be distributed by the end of second quarter 2014.
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 Court held a hearing on January 23, 2013 and has not ruled on this matter as of the date of this report. The Company has been negotiating with the retiree committee since July 2012, seeking a consensual agreement to terminate subsidized retiree medical coverage and life insurance coverage.
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. See Note 2 to American's Consolidated Financial Statements for the breakout of liabilities subject to compromise, including that related to pension and postretirement benefits.
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.

	-2	The Company’s weighted average diluted shares outstanding for all 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, 2012 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 two initial distributions made to date pursuant to the Company’s Plan, whereby holders of AAMRQ received shares of AAG Common Stock on the Effective Date, January 9, 2014 and February 10, 2014. 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 the approximate 13 million shares withheld by the Company in satisfaction of employee tax obligations.
	Former AAMRQ holders as of the Effective Date have and may in the future receive additional distributions based on the trading price of AAL common stock during the remaining 120 day period after the effective date and the total amount of allowed claims, in accordance with the terms of the Plan. Accordingly, the Company’s common shares outstanding and related GAAP basic and diluted EPS reported herein for all periods presented may change in the future, including amounts reported herein, to reflect additional retrospective adjustments for future common stock distributions to former holders of AAMRQ.
	The Company's fourth quarter 2013 performance reflects restructuring charges consisting of $1.7 billion related to labor-related claims, a $74 million accrual adjustment to the disputed claim reserve and a $218 million adjustment to claims related to the 3.5% premium (see Note 2 to AAG's Consolidated Financial Statements for additional information); merger-related charges include $192 million related to US Airways' pilot MOU that became effective upon the close of the Merger, $80 million related to professional fees and fees for US Airways to exit the Star Alliance, $58 million in severance to satisfy certain separation agreements resulting from the Merger, $56 million related to employee awards granted in connection with the merger, partially offset by a $67 million gain on the sale of slots at LaGuardia Airport as a result of the settlement reached with the DOJ; and special items including $107 million resulting from modifications and changes in assumptions for the pilot long-term disability plan in connection with the Chapter 11 process and $33 million to write down permanently grounded aircraft, partially offset by a gain related to the modification of our agreement with Citibank related to American's frequent flyer program.
	The Company's fourth quarter 2012 performance reflects restructuring charges and special items consisting of $361 million of severance related charges and write-off of leasehold improvements on aircraft and at airport facilities that were rejected during the Chapter 11 process and a $280 million benefit from a settlement of a commercial dispute. The second and third quarters of 2012 reflect $106 million and $211 million of such items, respectively.

These amounts are classified as Payable to affiliate on the accompanying consolidated balance sheets.
	Pursuant to a capacity purchase agreement between American and the American Eagle carriers, American receives all passenger revenue from flights performed for it by the American Eagle carriers and pays the American Eagle carriers a fee for each flight. The capacity purchase agreement reflects what American believes are current market rates received by third-party regional carriers for similar flying. Amounts paid to the American Eagle carriers under the capacity purchase agreement are available to pay for various operating expenses of the American Eagle carriers, such as crew expenses, maintenance, and other aircraft related expenses. As of December 31, 2013, the American Eagle carriers operated approximately 1,400 daily departures, offering scheduled passenger service to over 170 destinations in North America, Mexico and the Caribbean. On a separate company basis, AMR Eagle reported $1.2 billion in revenue in 2013. However, this historical financial information is not indicative of what AMR Eagle's future revenues might be if AMR Eagle were a stand-alone entity.
	In 2013 and 2012, American made payments to the American Eagle carriers of approximately $1.0 billion and $1.1 billion, respectively, related to the capacity purchase agreement. In addition, American incurred costs associated with generating third-party regional carriers' revenue for flights on AMR Eagle of $109 million and $128 million in 2013 and 2012, respectively, recorded in Regional expenses - fuel and Regional expenses - other in the accompanying consolidated statements of operations.
	In consideration for certain services provided, the AMR Eagle carriers paid American approximately $16 million, $16 million and $18 million in 2013, 2012 and 2011, respectively.

	Earnings (Loss) Per Share
	Pursuant to the Plan, all shares of our common stock outstanding prior to the Effective Date were canceled and the issuance of 756 million new shares of American Airlines Group Inc. common stock was authorized to satisfy allowed unsecured claims, labor-related deemed claims, and former AMR Corporation shareholder interests; to consummate the Merger; and to issue shares pursuant to the AAG Incentive Plans. As of the Effective Date, a combination of AAG Series A Preferred Stock and other bankruptcy settlement obligations were issued or placed into effect to satisfy allowed unsecured claims, labor-related deemed claims, and former AMR Corporation shareholder interests. As of December 31, 2013, approximately 261 million shares were issued by the Company primarily to consummate the Merger, distribute a specified number of initial shares to holders of labor-related deemed claims and former AMR Corporation shareholder interests, and to issue shares pursuant to the AAG Incentive Plans. Additionally, as of the Effective Date, the Company paid approximately $300 million in cash for employee withholding taxes in lieu of issuing shares which reduced the total number of shares to be issued pursuant to the Plan by approximately 13 million.
	As of December 31, 2013, approximately 463 million shares remain to be distributed pursuant to the Plan upon the conversion of AAG Series A Preferred Stock and to satisfy other bankruptcy settlement obligations related to allowed unsecured claims, including disputed claims, labor-related deemed claims and legacy AMR common stock shareholders. After the issuances of AAG Common Stock upon conversion of AAG Series A Preferred Stock and after the issuance of AAG Common Stock to satisfy the claim-related other bankruptcy settlement obligations, to the extent that any shares of AAG Common Stock remain undistributed, such shares will not be returned to us but rather will be distributed pro-rata to former AMR Corporation shareholders as of the Effective Date. Therefore approximately 743 million shares will have been distributed, however, the Company may on future distributions to employees remit cash for employee withholding taxes in lieu of distributing shares. Accordingly, as of the Effective Date, although undistributed shares are not yet issued and outstanding, all conditions of distribution except the passage of time have been met and such shares are considered issued and are included in our calculation of weighted average shares outstanding for both basic and diluted earnings per share.
	The cancellation of all shares of our common stock outstanding prior to the Effective Date and subsequent issuance of, pursuant to the Plan, AAG Common Stock to former AMR Corporation shareholder interests, represents a share exchange with the Company's owners that is accounted for as a reverse stock split applicable to all financial statement periods prior to the Effective Date. Accordingly, weighted average shares outstanding for all periods presented prior to the Effective Date include only the weighted average of common shares previously outstanding (traded as AAMRQ) which have been retroactively adjusted to reflect the reverse stock split. The retroactive adjustment for periods prior to the Effective Date has been made at a rate of 0.3735 shares of AAG Common Stock for each previously held share of AAMRQ, based upon all distributions to former AMR Corporation shareholder interests that have been made on or since the Effective Date, including those made on December 9, 2013, January 9, 2014, and February 10th, 2014. 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 the approximately 13 million shares withheld by the Company in satisfaction of employee tax obligations.
	Former AAMRQ holders as of the effective date have and may in the future receive additional distributions based on the trading price of AAL common stock during the remaining 120 day period after the effective date and the total amount of allowed claims, in accordance with the terms of the Plan. Further stock splits will occur as additional shares of AAG Common Stock are distributed to former AMR Corporation shareholders. Accordingly, the Company's common shares outstanding and related basic and diluted earnings per share reported herein for all periods presented may change in the future.

Accounting Policies [Line Items]	'
Basis of Presentation - Consolidation	'
	The Consolidated Financial Statements as of and for the years ended December 31, 2013, 2012 and 2011 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 AMR Eagle, for periods ended prior to December 9, 2013 and consolidated results of AAG, which includes American, AMR Eagle and US Airways Group, for periods ending on or after December 9, 2013. Accordingly, the Consolidated Financial Statements for the year ended December 31, 2013 include the accounts of US Airways Group for the 23 days ended December 31, 2013. Certain prior period amounts have been reclassified to conform to the current year financial statement presentation. All significant intercompany transactions have been eliminated.
Chapter 11 Matters	'
	Chapter 11 Matters
	In accordance with GAAP, the Debtors applied ASC 852 "Reorganizations" (ASC 852), in preparing the Consolidated Financial Statements. ASC 852 requires that the financial statements, for periods subsequent to the Chapter 11 Cases, 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 are recorded in Reorganization Items, Net on the accompanying Consolidated Statement of Operations. In addition, pre-petition obligations that may be impacted by the Chapter 11 reorganization process as of December 31, 2012 were classified on the Consolidated Balance Sheet in Liabilities Subject to Compromise.
	Certain of AMR's non-U.S. subsidiaries were not part of the Chapter 11 Cases. Since these non-US subsidiaries do not have significant transactions, AAG does not separately disclose the combined financial statements of such non-U.S. subsidiaries in accordance with the requirements of reorganization accounting.
	In accordance with ASC 852, AAG did not meet the criteria for and will not adopt "fresh start" accounting as the reorganization value of AMR's assets, as determined based upon an estimate of the fair value of AMR's equity using the trading market price of US Airways Group and the amount of post-petition liabilities as of the Effective Date was greater than total pre-petition liabilities and expected allowed claims. As a result, AAG's assets and liabilities were not adjusted to fair value.

New Accounting Pronouncements	'
	New Accounting Pronouncements
	Effective January 1, 2013, the Company adopted revised guidance on the Comprehensive Income topic of the FASB Codification which requires an entity to present, either parenthetically on the face of the financial statements or in the notes, significant amounts reclassified from each component of accumulated other comprehensive income (loss) and the income statement line items affected by the reclassification. The adoption did not have any impact on the Company’s financial position, results of operations or cash flows.
	Effective January 1, 2013, the Company adopted revised guidance on Balance Sheet topic of the FASB Codification, which clarifies the scope of disclosures about offsetting assets and liabilities. The clarification applies only to derivatives, repurchase agreements and reverse purchase agreements, and to certain securities borrowing and securities lending transactions, and not to ordinary trade receivables and payables. The adoption did not have any impact on the Company’s financial position, results of operations or cash flows.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States (GAAP) requires management to make estimates and assumptions that affect the amounts reported in the accompanying Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates.
Restricted Cash and Short-term Investments	'
	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, credit card processing holdback requirements.
Aircraft Fuel, Spare Parts, and Supplies, Net	'
	Aircraft fuel, spare parts, and supplies, net
	Aircraft fuel, spare parts, and supplies, 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.
Maintenance, Materials and Repairs	'
	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.
Goodwill	'
	Goodwill
	Goodwill represents the excess of the purchase price over the net fair value of the assets acquired and liabilities assumed by AAG on December 9, 2013, in connection with the Merger. Goodwill will not be amortized but tested for impairment annually.
Other Intangibles, Net	'
	Other Intangibles, net
	Intangible assets consist primarily of airport take-off and landing rights (Slots), customer relationships, market partners, international route authorities, 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.
	In connection with the application of acquisition accounting as of December 9, 2013, the intangible assets acquired from US Airways were measured at fair value using the market and income approaches. The Company utilized the market approach to value airport Slots, when sufficient market information was available, and included prices and other relevant information generated by market transactions involving comparable assets as well as pricing guides and other sources. The Company utilized the income approach to value the customer relationships and marketing agreements, certain international route authorities and the US Airways 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 following table provides information relating to the Company's amortized intangible assets as of December 31, 2013 and 2012 (in millions):
			2013				2012
	Airport Slots		$	332			$	515
	Customer relationships		300				—
	Marketing agreements		105				—
	Tradenames		35				—
	Airport gate leasehold rights		155				155
	Accumulated amortization		(373		)		(509		)
	Total		$	554			$	161
	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 will be amortized over approximately nine years, 30 years and 15 months, respectively.
	The Company recorded amortization expense related to these intangible assets of approximately $20 million, $25 million, and $27 million for the years ended December 31, 2013, 2012 and 2011, respectively. The Company expects to record annual amortization expense for the aforementioned definite-life intangible assets as follows (in millions):
			2014				2015				2016			2017		2018
	Amortization expense		$	79			$	54			$	48		$	44	$	40
	The Company'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, 2013, and 2012, the Company had $1.8 billion and $708 million, respectively, of indefinite-lived intangible assets on its Consolidated Balance Sheet.
Operating Property and Equipment	'
	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, 2013, 2012 and 2011 was $47 million, $50 million and $40 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		Shorter 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%, except when guaranteed by a third-party for a different amount.
	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.
Passenger Revenue	'
	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 statement of operations and recorded as a liability until remitted to the appropriate taxing authority.
Frequent Flyer Programs	'
	Frequent Flyer Programs
	The Company 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 and oneworld carriers and US Airways and Star Alliance carriers, respectively, as well as certain other partner airlines that participate in the programs. Effective March 31, 2014, US Airways will join the oneworld alliance and exit the Star Alliance. At that point, frequent travel reciprocity will be discontinued for many Star Alliance airlines. Mileage credits can also be earned through purchases from other non-airline partners that participate in our 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 our 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. In addition, the Company also includes in the determination of incremental cost the amount of certain fees related to redemptions expected to be collected from AAdvantage and Dividend Miles members. These redemption fees reduce incremental cost. No profit or overhead margin is included in the accrual of incremental cost. These estimates are generally updated based upon our 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, 2013, the liability for outstanding mileage credits expected to be redeemed for future travel awards for US Airways under the Dividend Miles program was $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, 2013 the liability for outstanding mileage credits for the AAdvantage program was $580 million 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 our adoption of Accounting Standards Update (ASU) No. 2009-13, "Revenue Recognition (Topic 605) - Multiple-Deliverable Revenue Arrangements" on January 1, 2011.
	During the fourth quarter, American and Citibank amended their current 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 will apply 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 the fourth quarter 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, 2013 and 2012, the Company had $1.5 billion and $1.2 billion, respectively 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, 2013, 2012 and 2011, the marketing component of mileage sales recognized at the time of sale in other revenues was approximately $834 million, $725 million and $761 million, respectively.
Income Taxes	'
	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.
Selling Expenses	'
	Selling Expenses
	Selling expenses include commissions, credit card fees, computerized reservations systems fees and advertising. Advertising expenses are expensed on a straight-line basis as incurred throughout the year. Advertising expense was $166 million, $153 million and $186 million for the years ended December 31, 2013, 2012 and 2011, respectively.
Deferred Gains and Credits, Net	'
	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 and certain vendor incentives.
Share-based Compensation	'
	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 12 for further discussion of share-based compensation.
Foreign Currency Gains and Losses	'
	Foreign Currency Gains and Losses
	Foreign currency gains and losses are recorded as part of other nonoperating expense, net in AAG's Consolidated Statements of Operations. Foreign currency losses for 2013, 2012 and 2011 were $56 million, $41 million and $17 million, respectively.

Basis of Presentation - Consolidation	'
	The Consolidated Financial Statements as of and for the years ended December 31, 2013, 2012 and 2011 include the accounts of American. Certain prior period amounts have been reclassified to conform to the current year financial statement presentation. All significant intercompany transactions have been eliminated.
Chapter 11 Matters	'
	Chapter 11 Matters
	In accordance with GAAP, the Debtors applied ASC 852 "Reorganizations" (ASC 852), in preparing the Consolidated Financial Statements. ASC 852 requires that the financial statements, for periods subsequent to the Chapter 11 Cases, 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 are recorded in Reorganization Items, Net on the accompanying Consolidated Statement of Operations. In addition, pre-petition obligations that may be impacted by the Chapter 11 reorganization process as of December 31, 2012 were classified on the Consolidated Balance Sheet in Liabilities Subject to Compromise.
	Certain of American's non-U.S. subsidiaries are not part of the Chapter 11 Cases. Since these non-US subsidiaries do not have significant transactions, American does not separately disclose the combined financial statements of such non-U.S. subsidiaries in accordance with the requirements of reorganization accounting.
	In accordance with ASC 852, American did not meet the criteria for and will not adopt "fresh start" accounting as the reorganization value of American's assets, as determined based upon an estimate of the fair value of AMR's equity using the trading market price of US Airways Group, the amount of post-petition liabilities as of the Effective Date was significantly greater than the total pre-petition liabilities and expected allowed claims. As a result, our assets and liabilities were not adjusted to fair value; but rather liabilities compromised by the Plan are stated at present values of amounts to be paid.

New Accounting Pronouncements	'
	New Accounting Pronouncements
	Effective January 1, 2013, American adopted revised guidance on the Comprehensive Income topic of the FASB Codification which requires an entity to present either parenthetically on the face of the financial statements or in the notes, significant amounts reclassified from each component of accumulated other comprehensive income (loss) and the income statement line items affected by the reclassification. The adoption did not have any impact on American’s financial position, results of operations or cash flows.
	Effective January 1, 2013, American adopted revised guidance on Balance Sheet topic of the FASB Codification, which clarifies the scope of disclosures about offsetting assets and liabilities. The clarification applies only to derivatives, repurchase agreements and reverse purchase agreements, and to certain securities borrowing and securities lending transactions, and not to ordinary trade receivables and payables. The adoption did not have any impact on the American’s financial position, results of operations or cash flows.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the accompanying Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates.
Restricted Cash and Short-term Investments	'
	Restricted 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	'
	Aircraft fuel, spare parts, and supplies, net
	Aircraft fuel, spare parts, and supplies, 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.
Maintenance, Materials and Repairs	'
	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.
Other Intangibles, Net	'
	Other Intangibles, net
	Intangible assets consist primarily of airport take-off and landing rights (Slots). 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.
	Indefinite-lived intangible assets (route acquisition costs and international Slots) are tested for impairment annually on December 31, rather than amortized, or when a triggering event occurs, in accordance with U.S. GAAP. Such triggering events may include significant changes to the Company's network or capacity, or the implementation of open skies agreements in countries where the Company operates flights.
	As there is minimal market activity for the valuation of routes and international Slots, the Company measures fair value with inputs using the income approach. The income approach uses valuation techniques, such as future cash flows, to convert future amounts to a single present discounted amount. The inputs utilized for these valuations are unobservable and reflect the Company's assumptions about market participants and what they would use to value the routes and accordingly are considered Level 3 in the fair value hierarchy. The Company's unobservable inputs are developed based on the best information available as of December 31, 2013.
	The following table provides information relating to the Company's amortized intangible assets as of December 31, 2013 and 2012 (in millions):
			2013				2012
	Airport Slots		$	277			$	515
	Airport gate leasehold rights		155				155
	Accumulated amortization		(375		)		(509		)
	Total		$	57			$	161
	Airport operating and gate lease rights are being amortized on a straight-line basis over 25 years to a zero residual value. The Dividend Miles customer relationships, marketing agreements and trademarks were identified as intangible assets subject to amortization and will be amortized over approximately 9 years, 30 years and 15 months, respectively.
	American recorded amortization expense related to these intangible assets of approximately $18 million, $25 million, and $27 million for the years ended December 31, 2013, 2012 and 2011, respectively. American expects to record annual amortization expense for the aforementioned definite-life intangible assets as follows (in millions):
			2014				2015				2016			2017		2018
	Amortization expense		$	12			$	10			$	9		$	5	$	1
	The Company'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, 2013, and 2012, the Company had $755 million and $708 million, respectively, of indefinite-lived intangible assets on its Consolidated Balance Sheet.
Operating Property and Equipment	'
	Equipment and Property
	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, 2013, 2012 and 2011 was $47 million, $50 million and $40 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
	American 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		Shorter 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%, except when guaranteed by a third-party for a different amount.
	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.
Passenger Revenue	'
	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 the Company's wholly-owned regional air carriers 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. American's wholly-owned regional air carriers 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 statement of operations and recorded as a liability until remitted to the appropriate taxing authority.
Frequent Flyer Programs	'
	Frequent Flyer Programs
	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 our frequent flyer liability incurred when AAdvantage members earn mileage credits by flying on American 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, 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. In addition, American also includes in the determination of incremental cost the amount of certain fees related to redemptions expected to be collected from AAdvantage members. These redemption fees reduce incremental cost. No profit or overhead margin is included in the accrual of incremental cost. These estimates are generally updated based upon our 12-month historical average of such costs.
	As of December 31, 2013 the liability for outstanding mileage credits for the AAdvantage program was $580 million 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 our adoption of Accounting Standards Update (ASU) No. 2009-13, "Revenue Recognition (Topic 605) - Multiple-Deliverable Revenue Arrangements" on January 1, 2011.
	During the fourth quarter, 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 will apply 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 the 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 the fourth quarter 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, 2013 and 2012, 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, 2013, 2012 and 2011, the marketing component of mileage sales recognized at the time of sale in other revenues was approximately $816 million, $725 million and $761 million, respectively.
Income Taxes	'
	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.
Selling Expenses	'
	Selling Expenses
	Selling expenses include commissions, credit card fees, computerized reservations systems fees and advertising. Advertising expenses are expensed on a straight-line basis as incurred throughout the year. Advertising expense was $166 million, $153 million and $186 million for the years ended December 31, 2013, 2012 and 2011, respectively.
Share-based Compensation	'
	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 11 for further discussion of share-based compensation.
Foreign Currency Gains and Losses	'
	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 2013, 2012 and 2011 were $55 million, $41 million and $17 million, respectively.

	-2	The Company’s weighted average diluted shares outstanding for all 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, 2012 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 two initial distributions made to date pursuant to the Company’s Plan, whereby holders of AAMRQ received shares of AAG Common Stock on the Effective Date, January 9, 2014 and February 10, 2014. 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 the approximate 13 million shares withheld by the Company in satisfaction of employee tax obligations.
	Former AAMRQ holders as of the Effective Date have and may in the future receive additional distributions based on the trading price of AAL common stock during the remaining 120 day period after the effective date and the total amount of allowed claims, in accordance with the terms of the Plan. Accordingly, the Company’s common shares outstanding and related GAAP basic and diluted EPS reported herein for all periods presented may change in the future, including amounts reported herein, to reflect additional retrospective adjustments for future common stock distributions to former holders of AAMRQ.

[1]	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 JFK and rejected bonds that financed certain improvements at ORD, which are included in the table above.
[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 agreements when the applicable motion was filed with the Bankruptcy Court to reject or modify such financing and the Debtors believed that it was probable the motion would be approved, and there was sufficient information to estimate the claim.
[3]	The Plan allows 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.

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 the approximate 13 million shares withheld by the Company in satisfaction of employee tax obligations.Former AAMRQ holders as of the Effective Date have and may in the future receive additional distributions based on the trading price of AAL common stock during the remaining 120 day period after the effective date and the total amount of allowed claims, in accordance with the terms of the Plan. Accordingly, the Company’s common shares outstanding and related GAAP basic and diluted EPS reported herein for all periods presented may change in the future, including amounts reported herein, to reflect additional retrospective adjustments for future common stock distributions to former holders of AAMRQ.

The year ended December 31, 2013 does not include the impact of post-petition interest recorded in first quarter of 2013. If such amounts were included, results would have been anti-dilutive and conversion would not have been assumed.
