	The accompanying unaudited condensed consolidated financial statements of US Airways Group, Inc. (“US Airways Group” or the “Company”) should be read in conjunction with the consolidated financial statements contained in US Airways Group’s Annual Report on Form 10-K for the year ended December 31, 2012. The accompanying unaudited condensed consolidated financial statements include the accounts of US Airways Group and its wholly owned subsidiaries. Wholly owned subsidiaries include US Airways, Inc. (“US Airways”), Piedmont Airlines, Inc. (“Piedmont”), PSA Airlines, Inc. (“PSA”), Material Services Company, Inc. (“MSC”) and Airways Assurance Limited (“AAL”). All significant intercompany accounts and transactions have been eliminated.
	Management believes that all adjustments necessary for the fair presentation of results, consisting of normally recurring items, have been included in the unaudited condensed consolidated financial statements for the interim periods presented. The preparation of financial statements in accordance with accounting principles generally accepted in the United States requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The most significant areas of judgment relate to passenger revenue recognition, impairment of long-lived and intangible assets, the frequent traveler program and the deferred tax asset valuation allowance. The Company’s accumulated other comprehensive loss balances at September 30, 2013 and December 31, 2012 related to pension and other postretirement benefits.

Earnings Per Share [Abstract]
Earnings Per Common Share	4. Earnings Per Common Share
	Basic earnings per common share (“EPS”) is computed on the basis of the weighted average number of shares of common stock outstanding during the period. Diluted EPS is computed on the basis of the weighted average number of shares of common stock plus the effect of potentially dilutive shares of common stock outstanding during the period using the treasury stock method. Potentially dilutive shares include outstanding employee stock options, employee stock appreciation rights (“SARs”), employee restricted stock units (“RSUs”) and convertible debt. The following table presents the computation of basic and diluted EPS (in millions, except share and per share amounts):

	2013 Citicorp Credit Facility
	On May 23, 2013, US Airways entered into a term loan credit facility (the “2013 Citicorp credit facility”) with Citicorp North America, Inc., as administrative agent, and a syndicate of lenders pursuant to which US Airways borrowed an aggregate principal amount of $1.6 billion. Approximately $1.3 billion of the net proceeds were applied to repay US Airways Group’s former Citicorp North America loan and certain other secured debt of US Airways with remaining net proceeds to be used for general corporate purposes. As a result of the repayment of this loan, the Company recorded approximately $8 million in special debt extinguishment charges which are included within other nonoperating expense, net on the accompanying condensed consolidated statement of operations. US Airways Group and certain other subsidiaries of US Airways Group are guarantors of the 2013 Citicorp credit facility.
	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”). The 2013 Citicorp credit facility is prepayable at any time with a premium of 1% applicable to certain prepayments made prior to November 23, 2013.
	The 2013 Citicorp credit facility bears interest at an index rate plus an applicable index margin or, at US Airways’ option, LIBOR (subject to a floor) plus an applicable LIBOR margin. As of September 30, 2013, the interest rate was 4.25% based on a 3.25% LIBOR margin for Tranche B-1 and 3.50% based on a 2.50% LIBOR margin for Tranche B-2.
	Tranche B-1 and Tranche B-2 mature on May 23, 2019 and November 23, 2016, respectively, and each is repayable in annual installments to be paid on each anniversary of the closing date in an amount equal to 1% 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 to operate between certain specified cities, certain take-off and landing rights at certain airports and certain other assets of US Airways.
	The 2013 Citicorp credit facility includes covenants that, among other things, (a) require US Airways to maintain (i) unrestricted liquidity of not less than $850 million prior to the Merger and AMR (or its successor) to maintain unrestricted liquidity of not less than $2 billion following the Merger, in both cases with not less than $750 million held in accounts subject to control agreements, and (ii) a minimum ratio of appraised value of collateral to the outstanding loans under the facility of 1.5 to 1.0 and (b) restrict the ability of US Airways Group and its subsidiaries party to the 2013 Citicorp credit facility (and after the Merger AMR, or its successor, and its subsidiaries party to the 2013 Citicorp credit facility) to make certain investments and restricted payments. The 2013 Citicorp credit facility contains events of default customary for similar financings, including a cross-acceleration provision to certain other material indebtedness of US Airways and the guarantors.
	6.125% Senior Notes
	On May 24, 2013, US Airways Group issued $500 million aggregate principal amount of 6.125% Senior Notes due 2018 (the “6.125% senior notes”), the net proceeds of which will be used for general corporate purposes. These notes bear interest at a rate of 6.125% per annum, which is payable semi-annually on each June 1 and December 1, beginning December 1, 2013. The 6.125% senior notes mature on June 1, 2018 and are fully and unconditionally guaranteed by US Airways. The 6.125% senior notes are general unsecured senior obligations of the Company.
	The 6.125% senior notes may be accelerated upon the occurrence of events of default, which are customary for securities of this nature. The Company, at its option, may redeem some or all of the 6.125% senior notes at any time at a redemption price equal to the greater of (1) 100% of the principal amount of the 6.125% senior notes to be redeemed and (2) a make-whole amount based on the sum of the present values of the remaining scheduled payments of principal and interest on the 6.125% senior notes discounted to the redemption date using a rate based on comparable U.S. Treasury securities plus 50 basis points, plus in either case accrued and unpaid interest to the redemption date. In the event of a specified change in control (not including the Merger), each holder may require the Company to repurchase all or a portion of their 6.125% senior notes for cash at a price equal to 101% of the principal amount of the 6.125% senior notes to be repurchased plus any accrued and unpaid interest, if any, to (but not including) the repurchase date.
	2013-1 EETCs
	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 September 30, 2013, $77 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 $58 million bearing interest at 3.95% per annum and Series B equipment notes in the amount of $19 million bearing interest at 5.375% per annum. Interest on the equipment notes is payable semiannually in May and November of each year, beginning 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 two Airbus aircraft delivered in September 2013. The equipment notes are secured by liens on aircraft. The remaining $743 million of escrowed proceeds will be used to purchase equipment notes as new aircraft are delivered.
	2012-2 EETCs
	In June 2013, US Airways created a new pass-through trust and issued a new class of its US Airways Pass Through Certificates, Series 2012-2: Class C in the aggregate face amount of $100 million. US Airways previously issued two classes of US Airways Pass Through Certificates, Series 2012-2: Class A and Class B in the aggregate face amount of $546 million, pursuant to separate trusts established for each of the Class A certificates and Class B certificates at the time of the issuance thereof in December 2012.
	As of September 30, 2013, US Airways has issued $563 million of equipment notes in three series under its 2012-2 EETCs: Series A equipment notes in the amount of $365 million bearing interest at 4.625% per annum, Series B equipment notes in the amount of $112 million bearing interest at 6.75% per annum and Series C equipment notes in the amount of $86 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 will begin in December 2013 for Series C. Principal payments on the Series A and Series B equipment notes are scheduled to begin 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 10 Airbus aircraft delivered from May 2013 through August 2013. The equipment notes are secured by liens on aircraft. The remaining $83 million of escrowed proceeds will be used to purchase equipment notes as new aircraft are delivered.
	Other Aircraft Financing Transactions
	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.
	In the third quarter of 2012, US Airways entered into an agreement to acquire five Embraer 190 aircraft from Republic Airline, Inc. (“Republic”). US Airways took delivery of three aircraft in 2012 and the remaining two aircraft in the first quarter of 2013. In connection with this agreement, US Airways assumed the outstanding debt on these aircraft upon delivery and Republic was released from its obligations associated with the principal due under the debt.
	7.25% Convertible Senior Notes
	In the first nine months of 2013, holders converted approximately $149 million principal amount of the 7.25% convertible senior notes, resulting in the issuance of approximately 32.6 million shares of the Company’s common stock. In connection with the conversion of these notes, the Company recorded approximately $28 million in special debt extinguishment charges which are included within other nonoperating expense, net on the accompanying condensed consolidated statement of operations.
	Barclays Prepaid Miles
	In July 2013, the Company repaid in full the Barclays prepaid miles loan at its face amount of $200 million plus accrued interest.
	Fair Value of Debt
	The carrying value and estimated fair value of the Company’s long-term debt was (in millions):

	Long-term debt, including current maturities	$	5,911		$	5,984		$	4,793	$	5,021
	The fair values were estimated using quoted market prices where available. For long-term debt not actively traded, fair values were estimated using a discounted cash flow analysis based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. If the Company’s long-term debt was measured at fair value, it would have been categorized as Level 2 in the fair value hierarchy.

	At December 31, 2012, gross net operating losses (“NOLs”) available for use by the Company were approximately $1.5 billion for federal income tax purposes. All of the Company’s NOLs are expected to be available for use in 2013 and expire during the years 2025 through 2031. The Company will use these NOLs to reduce its cash tax obligations when profitable going forward. The Company also had approximately $69 million of tax-effected state NOLs at December 31, 2012.
	At December 31, 2012, the Company was in a net deferred tax asset position for financial reporting purposes, which included the NOLs, and was subject to a full valuation allowance. The federal and state valuation allowances were $118 million and $42 million, respectively, which included $32 million allocated primarily to certain federal capital loss carryforwards.
	For each of the three and nine months ended September 30, 2013, the Company utilized NOLs to offset its taxable income. Historically, utilization of NOLs reduced the Company’s net deferred tax asset and in turn resulted in the release of its valuation allowance, which offset the Company’s tax provision dollar for dollar. In the second quarter of 2013, the Company’s pre-tax income and NOL utilization resulted in the use of its remaining valuation allowance associated with federal income taxes. Accordingly, with no remaining valuation allowance to release, the Company recorded $118 million and $183 million of non-cash federal income tax expense in the three and nine months ended September 30, 2013, respectively. The Company also recorded $2 million and $4 million of state income tax expense in the three and nine months ended September 30, 2013, respectively, related to certain states where NOLs were limited or unavailable to be used. As of September 30, 2013, the Company had approximately $1.2 billion of NOLs remaining for federal income tax purposes.
	For each of the three and nine months ended September 30, 2012, NOL usage and release of valuation allowance offset the Company’s tax provision. As a result, the Company did not record federal income tax expense and recorded $1 million of state income tax expense related to certain states where NOLs were limited or unavailable to be used.
	When profitable, the Company is ordinarily subject to Alternative Minimum Tax (“AMT”). However as the result of a special tax election made in 2009, the Company was able to utilize AMT NOLs to fully offset its AMT taxable income for each of the three and nine months ended September 30, 2013 and 2012.

The lawsuit alleges, among other things, that Sabre has engaged in anticompetitive practices that illegally restrain US Airways’ ability to distribute its products to its customers. The lawsuit also alleges that these actions have prevented US Airways from employing new competing technologies and have allowed Sabre to continue to charge US Airways supracompetitive fees. 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. The Company intends to pursue its claims against Sabre vigorously, but there can be no assurance of the outcome of this litigation.
	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 shareholders 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 Company’s Annual Meeting of Stockholders. The above-referenced action has been stayed pending the outcome of the antitrust lawsuit filed by the United States government and various states on August 13, 2013 (described below). The Company believes this lawsuit is without merit and intends to vigorously defend against the allegations.
	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 Airlines, Inc. as defendants, and on October 2, 2013, dismissed the initial California action. The Company believes this lawsuit is without merit and intends to vigorously defend against the allegations.
	On August 13, 2013, the United States government (acting under the U.S. Attorney General), along with the states of Arizona, Florida, Tennessee and Texas, the commonwealths of Pennsylvania and Virginia, and the District of Columbia, acting by and through their respective Attorneys General, filed a complaint against US Airways Group and AMR in the U.S. District Court for the District of Columbia. The plaintiffs allege, among other things, that the proposed Merger would substantially lessen competition in violation of Section 7 of the Clayton Act and seek to permanently enjoin the transaction. On September 5, 2013, the plaintiffs filed an amended complaint, adding the state of Michigan (by and through its Attorney General) as a plaintiff. On October 1, 2013, the state of Texas entered into an agreement with US Airways Group and AMR that resolved the state’s objections to the Merger, and its claims were dismissed with prejudice on October 7, 2013. The U.S. District Court has set a trial date of November 25, 2013. The Company believes this lawsuit is without merit and intends to vigorously defend against the allegations.
	The Company and/or its subsidiaries are defendants in various other pending lawsuits and proceedings, and from time to time are subject to other claims arising in the normal course of its business, many of which are covered in whole or in part by insurance. The outcome of those matters cannot be predicted with certainty at this time, but the Company, having consulted with outside counsel, believes that the ultimate disposition of these contingencies will not materially affect its consolidated financial position or results of operations.

The decrease in the intercompany payable to US Airways Group primarily resulted from the repayment of US Airways Group’s former Citicorp North America term loan and Barclays prepaid miles loan, offset in part by proceeds from the issuance of US Airways Group’s 6.125% Senior Notes.
	The net payable to US Airways Group’s wholly owned subsidiaries consists of amounts due under regional capacity agreements with the other airline subsidiaries and fuel purchase arrangements with a non-airline subsidiary.
