Chapter 11 Reorganization

Reorganizations [Abstract]

Chapter 11 Reorganization

Overview

On November 29, 2011 (the Petition Date), AMR Corporation (AMR), its principal subsidiary, American Airlines, Inc. (the Company) and certain of AMR'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). The Chapter 11 Cases are being jointly administered under the caption “In re AMR Corporation, et al., Case No. 11-15463-SHL.”

The Company and the other Debtors are operating as “debtors in possession” under the jurisdiction of the Bankruptcy Court and the applicable provisions of the Bankruptcy Code. In general, as debtors in possession under the Bankruptcy Code, we are authorized to continue to operate as an ongoing business but may not engage in transactions outside the ordinary course of business without the prior approval of the Bankruptcy Court. The Bankruptcy Code enables the Company to continue to operate its business without interruption, and the Bankruptcy Court has granted additional relief covering, among other things, obligations to (i) employees, (ii) taxing authorities, (iii) insurance providers, (iv) independent contractors for improvement projects, (v) foreign vendors, (vi) other airlines pursuant to certain interline agreements, and (vii) certain vendors deemed critical to the Debtors’ operations.

While operating as debtors in possession under Chapter 11 of the Bankruptcy Code, the Debtors may sell or otherwise dispose of or liquidate assets or settle liabilities, subject to the approval of the Bankruptcy Court or otherwise as permitted in the ordinary course of business. On April 15, 2013, the Company and other Debtors filed with the Bankruptcy Court its proposed Plan of Reorganization (the Plan) and related Disclosure Statement. The Debtors have an exclusive period to solicit and obtain acceptances of the Plan through and including July 29, 2013. It is possible that the Plan as filed may be challenged and undergo revision, perhaps substantially, prior to the time that it is finally approved by the Bankruptcy Court and submitted to the Debtors' stakeholders for a vote. The ultimate plan of reorganization, which would be subject to acceptance by the requisite majorities of empowered stakeholders under the Bankruptcy Code and approval by the Bankruptcy Court, could materially change the amounts and classifications in the Condensed Consolidated Financial Statements. See Note 13 to the Condensed Consolidated Financial Statements for further information on the plan of reorganization.

The Company’s Chapter 11 Cases followed an extended effort by the Company to restructure its business to strengthen its competitive and financial position. However, the Company’s substantial cost disadvantage compared to its larger competitors, all of which restructured their costs and debt through Chapter 11, became increasingly untenable given the accelerating impact of global economic uncertainty and resulting revenue instability, volatile and rising fuel prices, and intensifying competitive challenges.

Notwithstanding any indications of value that may be contained in the Plan, no assurance can be given as to the ultimate value, if any, that may be ascribed to the Debtors' various prepetition liabilities and other securities. The Company cannot predict what the ultimate value of any of its or the other Debtors' securities may be.

General Information

Notices to Creditors; Effect of Automatic Stay. The Debtors have notified all known current or potential creditors that the Chapter 11 Cases were filed. Subject to certain exceptions under the Bankruptcy Code, the filing of the Debtors’ Chapter 11 Cases automatically enjoined, or stayed, the continuation of most judicial or administrative proceedings or filing of other actions against the Debtors or their property to recover on, collect or secure a claim arising prior to the Petition Date. Thus, for example, most creditor actions to obtain possession of property from the Debtors, or to create, perfect or enforce any lien against the property of the Debtors, or to collect on monies owed or otherwise exercise rights or remedies with respect to a prepetition claim, are enjoined unless and until the Bankruptcy Court lifts the automatic stay as to any such claim. Vendors are being paid for goods furnished and services provided after the Petition Date in the ordinary course of business.

Appointment of Creditors’ Committee. On December 5, 2011, the U.S. Trustee appointed the Creditors’ Committee (Creditors' Committee) for the Chapter 11 Cases.

Retirement and Life Insurance Benefits. See Note 8 to the Condensed Consolidated Financial Statements for information regarding modifications to retirement and life insurance benefits.

Rejection of Executory Contracts. Under section 365 and other relevant sections of the Bankruptcy Code, the Debtors may assume, assume and assign, or reject certain executory contracts and unexpired leases, including, without limitation, agreements relating to aircraft and aircraft engines (collectively, Aircraft Property) and leases of real property, subject to the approval of the Bankruptcy Court and certain other conditions. As of March 31, 2013, the Bankruptcy Court had entered orders granting the Debtors' motions to assume 537 and reject 12 unexpired leases of non-residential real property and had entered various orders extending, by the Debtors' agreement with certain landlords, the date by which the Debtors must assume or reject an additional 24 unexpired leases of non-residential real property.

In general, rejection of an executory contract or unexpired lease is treated as a prepetition breach of the executory contract or unexpired lease in question and, subject to certain exceptions, relieves the Debtors from performing their future obligations under such executory contract or unexpired lease but entitles the contract counterparty or lessor to a prepetition general unsecured claim for damages caused by such deemed breach. Counterparties to such rejected contracts or leases have the right to file claims against the Debtors’ estate for such damages. Generally, the assumption of an executory contract or unexpired lease requires the Debtors to cure existing defaults under such executory contract or unexpired lease.

Any description of an executory contract or unexpired lease elsewhere in these Notes or in the report to which these Notes are attached, including where applicable the Debtors’ express termination rights or a quantification of their obligations, must be read in conjunction with, and is qualified by, any rights the Debtors or counterparties have under section 365 of the Bankruptcy Code.

The Debtors expect that liabilities subject to compromise and resolution in the Chapter 11 Cases will arise in the future as a result of damage claims created by the Debtors’ rejection of various executory contracts and unexpired leases. Due to the uncertain nature of many of the potential rejection claims, the magnitude of such claims is not reasonably estimable at this time. Such claims may be material (see “Liabilities Subject to Compromise” in Note 1 to the Condensed Consolidated Financial Statements).

Special Protection Applicable to Leases and Secured Financing of Aircraft and Aircraft Equipment. Notwithstanding the general discussion above of the impact of the automatic stay, under section 1110 of the Bankruptcy Code, beginning 60 days after filing a petition under Chapter 11, certain secured parties, lessors and conditional sales vendors may have a right to take possession of certain qualifying Aircraft Property that is leased or subject to a security interest or conditional sale contract, unless the Debtors, subject to approval by the Bankruptcy Court, agree to perform under the applicable agreement, and cure any defaults as provided in section 1110 (other than defaults of a kind specified in section 365(b)(2) of the Bankruptcy Code). Taking such action does not preclude the Debtors from later rejecting the applicable lease or abandoning the Aircraft Property subject to the related security agreement, or from later seeking to renegotiate the terms of the related financing.

The Debtors may extend the 60-day period by agreement of the relevant financing party, with Bankruptcy Court approval. In the absence of an agreement or cure as described above or such an extension, the financing party may take possession of the Aircraft Property and enforce its contractual rights or remedies to sell, lease or otherwise retain or dispose of such equipment.

The 60-day period under section 1110 in the Chapter 11 Cases expired on January 27, 2012. In accordance with the Bankruptcy Court’s Order Authorizing the Debtors to (i) Enter into Agreements Under Section 1110(a) of the Bankruptcy Code, (ii) Enter into Stipulations to Extend the Time to Comply with Section 1110 of the Bankruptcy Code and (iii) File Redacted Section 1110(b) Stipulations, dated December 23, 2011, the Debtors have entered into agreements to extend the automatic stay or agreed to perform and cure defaults under financing agreements with respect to certain aircraft in their fleet and other Aircraft Property. The Debtors have reached agreement on revised terms with respect to substantially all of the aircraft for which the Debtors expect to negotiate revised terms, subject in a number of instances to certain conditions, including reaching agreement on definitive documentation. The ultimate outcome of these negotiations cannot be predicted with certainty. To the extent the Debtors are unable to reach definitive agreements with Aircraft Property financing parties, those parties may seek to repossess the subject Aircraft Property. The loss of a significant number of aircraft could result in a material adverse effect on the Debtors’ financial and operating performance.

Magnitude of Potential Claims. On February 27, 2012, the Debtors filed with the Bankruptcy Court schedules and statements of financial affairs setting forth, among other things, the assets and liabilities of the Debtors, subject to the assumptions filed in connection therewith. All of the schedules are subject to further amendment or modification.

Bankruptcy Rule 3003(c)(3) requires the Bankruptcy Court to fix the time within which proofs of claim must be filed in a Chapter 11 case pursuant to section 501 of the Bankruptcy Code. This Bankruptcy Rule also provides that any creditor who asserts a claim against the Debtors that arose prior to the Petition Date and whose claim (i) is not listed on the Debtors' schedules or (ii) is listed on the schedules as disputed, contingent, or unliquidated, must file a proof of claim. On May 4, 2012, the Bankruptcy Court entered an order that established July 16, 2012 at 5:00 p.m. (Eastern Time) (the Bar Date) as the deadline to file proofs of claim against any Debtor. More information regarding the filing of proofs of claim can be obtained at www.amrcaseinfo.com. Information on this website is not incorporated into or otherwise made a part of this report.

As of April 10, 2013, approximately 13,400 claims totaling about $290.0 billion have been filed with the Bankruptcy Court against the Debtors. Of those claims, approximately 350 claims aggregating approximately $58 million were filed after the Bar Date. We expect new and amended claims to be filed in the future, including claims amended to assign values to claims originally filed with no designated value. We intend to dispute the claims filed after the Bar Date as not having been filed timely and in accordance with the Bankruptcy Code. We have identified, and we expect to continue to identify, many claims that we believe should be disallowed by the Bankruptcy Court because they are duplicative, are without merit, are overstated or for other reasons. As of April 10, 2013, the Bankruptcy Court has disallowed approximately $100.2 billion of claims and has not yet ruled on our other objections to claims, the disputed portions of which aggregate to an additional $16.1 billion. We expect to continue to file objections in the future. Because the process of analyzing and objecting to claims is ongoing, the amount of disallowed claims may increase significantly in the future. The Debtors have recorded amounts for claims for which there was sufficient information to estimate the claim.

Differences between amounts scheduled by the Debtors and claims by creditors will be investigated and resolved in connection with the claims resolution process. In light of the expected number of creditors, the claims resolution process may take considerable time to complete. Accordingly, the ultimate number and amount of allowed claims is not presently known, nor can the ultimate recovery with respect to allowed claims be presently ascertained.

Collective Bargaining Agreements. Section 1113(c) of the Bankruptcy Code provides a process for the modification and/or rejection of collective bargaining agreements (CBAs). Through this process, American was able to achieve new CBAs with each of its unions (TWU, APFA and APA), covering nine unionized work groups.

In September 2012, the Bankruptcy Court authorized American to reject its pilot CBA, and thereafter American began implementing certain terms and conditions of employment for pilots. American and the APA continued to negotiate in good faith toward a new pilot agreement, and those negotiations resulted in a new pilot CBA that was approved by the Bankruptcy Court on December 19, 2012. A small group of American pilots is appealing the Bankruptcy Court's decisions granting American's request to reject the pilot CBA and approving the new pilot CBA, and those appeals are pending in the U.S. District Court for the Southern District of New York.

American Eagle Airlines, Inc. (AMR Eagle) also engaged in the Section 1113(c) process with its unions, and ultimately achieved new CBAs with AFA, ALPA and all four TWU-represented work groups.

In addition, American's pilots, flight attendants, and ground employee unions and the US Airways, Inc. pilots union have agreed to terms for improved CBAs, effective upon the closing of AMR's proposed merger with US Airways Group, Inc. (US Airways Group) (see Note 12 and Note 13 to the Condensed Consolidated Financial Statements for further information regarding the merger). The US Airways, Inc. flight attendants union has also reached a tentative agreement with US Airways, Inc., which includes support for the merger. American's unions representing pilots and flight attendants are working with their counterparts at US Airways, Inc. to determine representation and single agreement protocols to be used to integrate workforce after the merger.

Merger Agreement and Plan of Reorganization. See Notes 12 and 13 to the Condensed Consolidated Financial Statements for information regarding the Merger Agreement and Plan.

Availability and Utilization of Net Operating Losses. The availability and utilization of net operating losses (and utilization of alternative minimum tax credits) after the Debtors' emergence from Chapter 11 is uncertain at this time and will be highly influenced by the composition of the plan of reorganization that is ultimately pursued. On January 27, 2012, the Bankruptcy Court issued a Final Order Establishing Notification Procedures for Substantial Claimholders and Equityholders and Approving Restrictions on Certain Transfers of Interests in the Debtors' Estates, which restricted trading in the Company's common stock and established certain procedures and potential restrictions with respect to the transfer of claims. The order was intended to prevent, or otherwise institute procedures and notification requirements with respect to, certain transfers of AMR Common Stock and unsecured claims against the Debtors that could impair the ability of the Debtors to use their net operating loss carryovers and certain other tax attributes on a reorganized basis. However, the Original Procedures did not envision the proposed merger between AMR and US Airways Group and, if implemented to take into account the proposed merger or an equivalent transaction, might have unduly restricted the amount of claims that may be accumulated and retained by certain holders. Accordingly, on February 22, 2013, the Debtors filed a motion with the Bankruptcy Court to revise the Original Procedures (as so revised, the Revised Procedures).

On April 11, 2013, the Bankruptcy Court entered an order (the Revised Order) approving the Revised Procedures.

With respect to holders of unsecured claims against the Debtors, the Revised Procedures establish a process in which holders of unsecured claims in excess of a threshold amount may be required to file one or more Notices of Substantial Claim Ownership, and, under certain circumstances, may be required to sell all or a portion of any unsecured claims acquired during the Chapter 11 Cases. The Revised Procedures potentially apply to any person that beneficially owns either (1) more than $190 million of claims against the Debtors or (2) a lower amount of claims which, when added to certain specified interests, including stock, in AMR or US Airways Group, would result in such holder holding the “Applicable Percentage,” generally 4.5 percent, of the reorganized Debtors. In connection with the filing of a Notice of Substantial Claim Ownership, a holder must indicate if it will agree to refrain from acquiring additional AMR and US Airways Group common stock and such other specified interests until after the effective date of the Debtors' Chapter 11 plan of reorganization, and to dispose of any such interests acquired since February 22, 2013. This can affect the manner in which the Revised Procedures apply to certain holders.

The Revised Procedures did not alter the procedures applicable with respect to “Substantial Equityholders,” namely persons who are, or as a result of a transaction would become, the beneficial owner of approximately 4.5 percent of the outstanding shares of AMR Common Stock.

Any acquisition, disposition, or other transfer of equity or claims in violation of the restrictions set forth in the Revised Order will be null and void ab initio and/or subject to sanctions as an act in violation of the automatic stay under sections 105(a) and 362 of the United States Bankruptcy Code.

Liabilities Subject to Compromise

The following table summarizes the components of liabilities subject to compromise included on the Condensed Consolidated Balance Sheet as of March 31, 2013 and December 31, 2012:



(in millions)
	March 31, 2013		December 31, 2012
Long-term debt	$	358	$	358
Estimated allowed claims on aircraft lease and debt obligations and facility lease and bond obligations	3,874		3,716
Pension and postretirement benefits	1,237		1,250
Accounts payable and other accrued liabilities	314		370
Other	—		—
Total liabilities subject to compromise	$	5,783	$	5,694

Long-term debt, including undersecured debt, classified as subject to compromise as of March 31, 2013 and December 31, 2012 consisted of (in millions):



	March 31, 2013		December 31, 2012
Secured variable and fixed rate indebtedness due through 2023 (effective rates from 1.00% - 13.00% at March 31, 2013)	$	172	$	172
6.00%—8.50% special facility revenue bonds due through 2036	186		186
	$	358	$	358

Liabilities subject to compromise refers to prepetition obligations which may be impacted by the Chapter 11 reorganization process. These amounts represent the Debtors’ current estimate of known or potential prepetition obligations to be resolved in connection with the Chapter 11 Cases.

In accordance with ASC 852, substantially all of the Company’s unsecured debt has been classified as liabilities subject to compromise. Additionally, certain of the Company’s undersecured debt instruments have also been classified as liabilities subject to compromise.

Pursuant to the Support Agreement, as defined and further described in Note 12 to the Condensed Consolidated Financial Statements, the Debtors agreed to allow certain post-petition unsecured claims on obligations. As a result, the Company recorded interest charges of $116 million to liabilities subject to compromise to recognize post-petition interest expense on unsecured obligations.

As a result of the modifications to the retirement benefits as discussed in Note 8 to the Condensed 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. as of March 31, 2013.

Differences between liabilities the Debtors have estimated and the claims filed, or to be filed, will be investigated and resolved in connection with the claims resolution process. The Company will continue to evaluate these liabilities throughout the Chapter 11 Cases and adjust amounts as necessary. Such adjustments may be material. In light of the expected number of creditors, the claims resolution process may take considerable time to complete. Accordingly, the ultimate number and amount of allowed claims is not presently known.

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 three months ended March 31, 2013 and March 31, 2012:

(1)

Amounts include allowed claims (claims approved by the Bankruptcy Court) and estimated allowed claims relating to the rejection or modification of financings related to aircraft. The Debtors record an estimated claim associated with the rejection or modification of a financing when the applicable motion is filed with the Bankruptcy Court to reject or modify such financing and the Debtors believe that it is probable the motion will be approved, and there is sufficient information to estimate the claim. Modifications of the financings related to certain aircraft remain subject to conditions, including reaching agreement on definitive documentation. See above, “Special Protection Applicable to Leases and Secured Financing of Aircraft and Aircraft Equipment,” for further information.

(2)

Amounts include allowed claims (claims approved by the Bankruptcy Court) and estimated allowed claims relating to entry of orders treating as unsecured claims with respect to facility agreements supporting certain issuances of special facility revenue bonds. The Debtors record an estimated claim associated with the treatment of claims with respect to facility agreements when the applicable motion is filed with the Bankruptcy Court and the Debtors believe that it is probable that the motion will be approved, and there is sufficient information to estimate the claim. See above, “Rejection of Executory Contracts,” for further information.

(3)

Pursuant to the Support Agreement, as defined and further described in Note 12 to the Condensed Consolidated Financial Statements, the Debtors agreed to allow certain post-petition unsecured claims on obligations. As a result, the Company recorded reorganization charges to adjust estimated allowed claim amounts previously recorded on rejected special facility revenue bonds of $127 million, which is included in the table above.

Claims related to reorganization items are reflected in liabilities subject to compromise on the Condensed Consolidated Balance Sheet as of March 31, 2013.

Accounting Policies [Abstract]
Basis Of Presentation	Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with United States (U.S.) generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, these financial statements contain all adjustments, consisting of normal recurring accruals, necessary to present fairly the financial position, results of operations and cash flows for the periods indicated. Results of operations for the periods presented herein are not necessarily indicative of results of operations for the entire year. American is a wholly owned subsidiary of AMR. The Condensed Consolidated Financial Statements also include the accounts of variable interest entities for which the Company is the primary beneficiary. For further information, refer to the consolidated financial statements and footnotes included in the American Annual Report on Form 10-K filed on February 20, 2013, as amended by the Form 10-K/A filed on April 16, 2013 (2012 Form 10-K). In accordance with GAAP, the Debtors have applied ASC 852 “Reorganizations” (ASC 852), in preparing the Condensed 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, prepetition obligations that may be impacted by the Chapter 11 reorganization process have been classified on the Condensed Consolidated Balance Sheet in liabilities subject to compromise. These liabilities are reported at the amounts expected to be allowed by the Bankruptcy Court, even if they may be settled for lesser amounts. Certain of our non-U.S. subsidiaries were not part of the Chapter 11 filings. Since the non-US subsidiaries not part of the bankruptcy filing do not have significant transactions, we do not separately disclose the condensed combined financial statements of such non-U.S. subsidiaries in accordance with the requirements of reorganization accounting. These Condensed Consolidated Financial Statements have also been prepared on a going concern basis, which contemplates continuity of operations, realization of assets and satisfaction of liabilities in the ordinary course of business. Accordingly, the Condensed Consolidated Financial Statements do not include any adjustments relating to the recoverability of assets and classification of liabilities that might be necessary should the Debtors be unable to continue as a going concern. As a result of the Chapter 11 Cases, the satisfaction of our liabilities and funding of ongoing operations are subject to uncertainty and, accordingly, there is a substantial doubt of the Company’s ability to continue as a going concern. The accompanying Condensed Consolidated Financial Statements do not purport to reflect or provide for the consequences of the Chapter 11 Cases, other than as set forth under “liabilities subject to compromise” on the accompanying Condensed Consolidated Balance Sheet and “income (loss) before reorganization items” and “reorganization items, net” on the accompanying Consolidated Statement of Operations (see Note 1 to the Condensed Consolidated Financial Statements). In particular, the financial statements do not purport to show (1) as to assets, their realizable value on a liquidation basis or their availability to satisfy liabilities; (2) as to prepetition liabilities, the amounts that may be allowed for claims or contingencies, or the status and priority thereof; or (3) as to operations, the effect of any changes that may be made to the Debtors’ business.

Commitments, Contingencies and Guarantees

Restructuring of Agreements with The Boeing Company and Amendment of Agreement with Airbus S.A.S.

American entered into an agreement on January 11, 2013 (the Restructuring Agreement) with Boeing that provides for the assumption and restructuring of certain existing aircraft purchase agreements (the Restructured Aircraft Purchase Agreements) between Boeing and American, the entering into of a definitive purchase agreement (the MAX purchase agreement) with respect to Boeing 737 MAX aircraft (the MAX aircraft), certain financing commitments for the Boeing 787 aircraft (the 787 aircraft) and certain Boeing 737-8 aircraft (the 737 aircraft), the assumption of certain other aircraft spare parts, support and services agreements, and a comprehensive settlement of the relationship among American and its affiliates and Boeing and certain affiliates of Boeing, including all claims asserted by Boeing and such affiliates in the Chapter 11 Cases, with certain limited exceptions.

The Bankruptcy Court issued an order on January 23, 2013 approving the Restructuring Agreement, assumption of the Restructured Aircraft Purchase Agreements, and the MAX purchase agreement. The Restructured Aircraft Purchase Agreements provide for the substitution of 787-8 aircraft for certain 787-9 aircraft, an accelerated delivery schedule for the 787 aircraft with deliveries scheduled to commence in November 2014 and continue in each calendar year through September 2018, and the confirmation of the purchase of the Boeing 787 aircraft, which previously had been subject to certain reconfirmation rights. Under the Restructured Aircraft Purchase Agreements, American will have the option to purchase 40 737 aircraft, 13 777 aircraft and 58 787 aircraft.

Pursuant to the Restructuring Agreement, American entered into the MAX purchase agreement pursuant to which American will acquire 100 MAX aircraft, equipped with new, more fuel efficient engines. The MAX purchase agreement constitutes the definitive purchase agreement contemplated by, and supersedes, the agreement entered into by American and Boeing on July 19, 2011 (the 2011 MAX order) that provided for the commitment of American to purchase such MAX aircraft (referred to in the 2011 MAX order as 737RE aircraft). The 2011 MAX order was subject to a number of contingencies, including the parties entering into a definitive purchase agreement and Boeing's approval of the launch of the Boeing 737 re-engined aircraft program, which was approved in August, 2011. Under the MAX purchase agreement, MAX aircraft are scheduled to be delivered to American in each of the years 2018 through 2022. In addition, under the MAX purchase agreement, American will have the option to purchase 60 additional MAX aircraft in the years 2020-2025.

American also, on January 11, 2013, entered into an amendment to the A320 Family Aircraft Purchase Agreement with Airbus, dated July 20, 2011 (the Airbus Amendment) specifying the scheduled delivery months of certain aircraft and revising the date by which American must notify Airbus of the engine selection of certain aircraft types. The Airbus Amendment became effective on January 23, 2013, when the Court entered an order approving assumption of the A320 Family Purchase Agreement. Agreements pursuant to which Airbus agreed to providing financing for the purchase of certain aircraft also were assumed.

American had total aircraft acquisition commitments as of March 31, 2013 as follows:



		Boeing				Airbus
		737 Family	737 MAX	777-300 ER	787 Family	A320 Family	A320 NEO	Total
Remainder of 2013	Purchase	22	—	5	—	—	—	27

Total	Purchase	38	100	15	42	—	130	325
Total	Lease	64	—	—	—	130	—	194

As of March 31, 2013, and subject to assumption of certain of the related agreements, payments for the above purchase commitments and certain engines will approximate $1.6 billion in the remainder of 2013, $1.9 billion in 2014, $1.7 billion in 2015, $2.1 billion in 2016, $2.1 billion in 2017, and $12.6 billion for 2018 and beyond. These amounts are net of purchase deposits currently held by the manufacturers. American has granted Boeing a security interest in American’s purchase deposits with Boeing. The Company’s purchase deposits totaled $721 million as of March 31, 2013.

As of March 31, 2013, and subject to assumption of certain of the related agreements, total future lease payments for all leased aircraft, including aircraft not yet delivered, will approximate $624 million in the remainder of 2013, $945 million in 2014, $1.2 billion in 2015, $1.4 billion in 2016, $1.6 billion in 2017, and $11.7 billion in 2018 and beyond.

In 2010, American and Japan Airlines (JAL) entered into a Joint Business Agreement (JBA) under which, amongst other things, American provided JAL a guarantee of certain minimum incremental revenue resulting from the successful operation of the joint business for the first three years following its implementation (which period will end June 30, 2015), subject to certain terms and conditions. The amount required to be paid by the Company under the guarantee in any one of such years may not exceed $100 million, and is reduced if capacity for one of such years is less than a defined base year period capacity. Based on current Trans-Pacific capacity, the guarantee in any one of such years may not exceed approximately $85 million. As of March 31, 2013, based on an expected probability model, American had a recorded guarantee liability that is not material.

Capacity Purchase Agreements with Third Party Regional Airlines

During 2012, American entered into capacity purchase agreements with SkyWest Airlines, Inc. (SkyWest) and with ExpressJet Airlines, Inc. (ExpressJet), both wholly owned subsidiaries of SkyWest, Inc., to provide 50-seat regional jet feed. Both airlines operate the services under the American Eagle^® brand. SkyWest began service from Los Angeles International Airport on November 15, 2012, and ExpressJet began service from Dallas-Ft. Worth International Airport on February 14, 2013. In addition, Chautauqua Airlines, Inc. (Chautauqua) continues to operate under the brand AmericanConnection^®under a capacity purchase agreement with American.

On January 23, 2013, American entered into a 12 year capacity purchase agreement with Republic Airline Inc. (Republic), a subsidiary of Republic Airways Holdings, to provide large regional jet flying. Through the agreement, Republic will acquire 47 Embraer E-175 aircraft featuring a two-class cabin with 12 first class seats and 64 seats in the main cabin. The aircraft, which will fly under the American Eagle^® brand, will phase into operation at approximately two to three aircraft per month beginning in mid-2013. All 47 aircraft are expected to be in operation by the first quarter of 2015.

As of March 31, 2013, American's minimum fixed obligations under its capacity purchase agreements with third party regional airlines were approximately $257 million in the remainder of 2013, $521 million in 2014, $670 million in 2015, $676 million in 2016, $520 million in 2017 and $4.4 billion in 2018 and beyond. These obligations contemplate minimum levels of flying by the third party airlines under the respective agreements and also reflect assumptions regarding certain costs associated with the minimum levels of flying such as the cost of fuel, insurance, catering, property tax and landing fees. Accordingly, actual payments under these agreements could differ materially from the minimum fixed obligations set forth above.

Other

As a result of the filing of the Chapter 11 Cases, attempts to prosecute, collect, secure or enforce remedies with respect to prepetition claims against the Debtors are subject to the automatic stay provisions of Section 362(a) of the Bankruptcy Code, except in such cases where the Bankruptcy Court has entered an order modifying or lifting the automatic stay. Notwithstanding the general application of the automatic stay described above, governmental authorities, both domestic and foreign, may determine to continue actions brought under their regulatory powers. Therefore, the automatic stay may have no effect on certain matters, and the Debtors cannot predict the impact, if any, that its Chapter 11 Cases might have on its commitments and obligations.

Income Taxes	3 Months Ended
Income Taxes	Mar. 31, 2013
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company provides a valuation allowance for deferred tax assets when it is more likely than not that some portion, or all, of its deferred tax assets will not be realized. The Company’s deferred tax asset valuation allowance increased from $5.1 billion as of December 31, 2012 to $5.2 billion as of March 31, 2013, including the impact of comprehensive income for the three months ended March 31, 2013 and changes from other adjustments. These other adjustments include the realization of an income tax expense credit of approximately $30 million recorded for the three months ended March 31, 2013 by the Company as a result of passage of the American Taxpayer Relief Act of 2012. There was no amount of adjustment recorded by the Company during the quarter ended March 31, 2012. 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. Due to the significant volatility of items impacting other comprehensive income on a quarterly basis, the Company generally does not record any such tax benefit allocation until all items impacting other comprehensive income are known for the annual period. Thus, any such interim tax benefit allocation may subsequently be subject to reversal.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

The financings listed in the table above are considered not subject to compromise. For information regarding the liabilities subject to compromise, see Note 1 to the Condensed Consolidated Financial Statements.

The Company’s future long-term debt and operating lease payments have changed as its ordered aircraft are delivered and such deliveries have been financed. As of March 31, 2013, maturities of long-term debt (including sinking fund requirements) for the next five years are:



Years Ending December 31 (in millions)	Principal Not Subject to Compromise		Principal Subject to Compromise		Total Principal Amount
Remainder of 2013	$	1,004	$	93	$	1,097
2014	870		152		1,022
2015	768		5		773
2016	1,762		5		1,767
2017	503		42		545

Principal Not Subject to Compromise and Subject to Compromise includes payments not made due to the Chapter 11 Cases of $451 million and $64 million, respectively.

Future minimum lease payments required under operating leases that have initial or remaining non-cancelable lease terms in excess of a year as of March 31, 2013, were: remainder of 2013 – $853 million, 2014 – $1.0 billion, 2015 – $977 million, 2016 – $900 million, 2017 – $860 million, and 2018 and beyond – $5.1 billion. As of March 31, 2013, $201 million and $163 million are included on the accompanying balance sheet in Liabilities Subject to Compromise and Accrued liabilities and other liabilities and deferred credits, respectively, relating to rent expense being recorded in advance of future operating lease payments.

As of March 31, 2013, AMR had issued guarantees covering approximately $1.5 billion of American’s tax-exempt bond debt (and interest thereon) and $4.1 billion of American’s secured debt (and interest thereon). American had issued guarantees covering approximately $842 million of AMR’s unsecured debt (and interest thereon).

EETC Transactions

On March 12, 2013, American closed its private offering of two tranches of enhanced equipment trust certificates (the Series 2013-1 EETCs) in the aggregate face amount of $664 million. The Series 2013-1 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 2013-1 EETCs represent an interest in the assets of two separate pass through trusts, each of which hold equipment notes issued or expected to be 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. The equipment notes are secured by eight currently owned Boeing 737-823 aircraft and one currently owned Boeing 777-223ER aircraft and are expected to be secured by four new Boeing 777-323ER aircraft currently scheduled for delivery to American during the period from April 2013 to July 2013. 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).

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 postpetition 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 prepetition 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. American expects the Refinancing EETC structure to be substantially similar to the structure of the Series 2011-2 Pass Through Certificates, other than the economic terms (such as the interest rate) and certain terms and conditions to be in effect during its current Chapter 11 bankruptcy case.

The Bankruptcy Court approved the motion on January 17, 2013 and entered an order (the EETC Order) pursuant to such effect on February 1, 2013. The trustees for the Existing Financings have appealed the EETC Order and judgments rendered in certain related adversary proceedings. The appeals are currently being briefed before the Second Circuit Court of Appeals and will be fully submitted by April 30, 2013. The Company intends to continue to assert vigorously its rights to repay the Existing Financings without the payment of any make-whole amount or other premium or prepayment penalty, and the Company is considering all of its options, including the payment of the Existing Financings and closing the Refinancing EETC notwithstanding such appeal. There can be no assurance that the refinancing EETC will be able to be effected on acceptable terms, if at all.

Sale-leaseback Arrangements

American has entered into sale-leaseback arrangements with certain leasing companies to finance 32 Boeing 737-800 aircraft scheduled to be delivered from April 2013 through 2014. The financings of each aircraft under these arrangements are subject to certain terms and conditions. In addition, in some instances, they are also subject to collaboration with the Creditors' Committee and other key stakeholders and to the approval of the Bankruptcy Court.

During the first three months of 2013, American financed 8 Boeing 737-800 and three Boeing 777-300ER aircraft under sale-leaseback arrangements, which are accounted for as operating leases. These sale-leaseback transactions resulted in gains which are being amortized over the respective remaining lease terms.

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) 10.5% $450 million Senior Secured Notes due 2012 (the 10.5% Notes) and (2) Senior Secured Notes, as described below:



	10.5% Notes		Senior Secured Notes
Frequency of Appraisals	Semi-Annual (April and October)		Semi-Annual (June and December)
LTV Requirement	43%; failure to meet collateral test requires posting of additional collateral		1.5x Collateral valuation to amount of debt outstanding (67% LTV); failure to meet collateral test results in American paying 2% additional interest until the ratio is at least 1.5x; additional collateral can be posted to meet this requirement
LTV as of Last Measurement Date	47.5%		38.8%
			Generally, certain route authorities, take-off and landing slots, and rights to airport facilities used by American to operate certain services between the U.S. and London Heathrow, Tokyo Narita/Haneda, and China
Collateral Description	143 aircraft consisting of:
	Type	# of Aircraft

	MD-80	74
	B757-200	41
	B767-200ER	3
	B767-300ER	25
	TOTAL	143

At March 31, 2013, the Company was in compliance with the most recently completed collateral coverage tests for the Senior Secured Notes. As of March 31, 2013, American had $41 million of cash collateral posted with respect to the 10.5% notes, which matured in 2012. The Company has not satisfied the debt with respect to the 10.5% notes due to the ongoing Chapter 11 Cases.

Other

Almost all of the Company’s aircraft assets (including aircraft and aircraft-related assets eligible for the benefits of section 1110 of the Bankruptcy Code) are encumbered, and the Company has a very limited quantity of assets which could be used as collateral in financing.

The Chapter 11 Cases triggered defaults on substantially all debt and lease obligations of the Debtors. However, under section 362 of the Bankruptcy Code, the commencement of a Chapter 11 case automatically stays most creditor actions against the Debtors’ estates.

As discussed in Note 1 to the Condensed Consolidated Financial Statements, the Company has been using the benefits afforded by the Bankruptcy Code to restructure the terms of much of its indebtedness and lease obligations. The Company cannot predict at this time the outcome of its efforts to restructure its indebtedness and lease obligations. It is possible that holders of the Company's unsecured indebtedness may lose a portion of their investment depending on the outcome of the Chapter 11 Cases.

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

Fair Value Measurements

The Company utilizes the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. The Company’s short-term investments classified as Level 2 primarily utilize broker quotes in a non-active market for valuation of these securities. The Company’s fuel derivative contracts, which consist primarily of collars (consisting of a purchased call option and a sold put option) and call spreads (consisting of a purchased call option and a sold call option), are valued using energy and commodity market data which is derived by combining raw inputs with quantitative models and processes to generate forward curves and volatilities. Heating oil, jet fuel and crude oil are the primary underlying commodities in the hedge portfolio. No changes in valuation techniques or inputs occurred during the three months ended March 31, 2013.

Assets and liabilities measured at fair value on a recurring basis are summarized below:



(in millions)	Fair Value Measurements as of March 31, 2013

¹ Unrealized gains or losses on short-term investments, restricted cash and short-term investments and derivatives qualifying for hedge accounting are recorded in Accumulated other comprehensive income (loss) at each measurement date.

² The Company’s short-term investments mature in one year or less except for $350 million of Bank notes/Certificates of deposit/Time deposits, $609 million of U.S. Government agency investments and $470 million of Corporate obligations which have maturity dates exceeding one year.

No significant transfers between Level 1 and Level 2 occurred during the three months ended March 31, 2013. The Company’s policy regarding the recording of transfers between levels is to reflect any such transfers at the end of the reporting period.

As of March 31, 2013, the Company had no exposure to European sovereign debt.

The fair values of the Company’s long-term debt classified as Level 2 were estimated using quoted market prices or discounted cash flow analyses, based on the Company’s current estimated incremental borrowing rates for similar types of borrowing arrangements. All of the Company’s long term debt not classified as subject to compromise is classified as Level 2.

The carrying value and estimated fair values of the Company’s long-term debt, including current maturities, not classified as subject to compromise, were (in millions):

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, and the Pension Relief Act of 2010. As a result of the Chapter 11 Cases, AMR contributed $33 million to its U.S. defined benefit pension plans during the first quarter of 2013 covering post-petition periods. The Company’s remaining 2013 contributions to its defined benefit pension plans are subject to the Chapter 11 proceedings. Prior to the closing of the Merger (see Note 13 to the Condensed Consolidated Financial Statements for further information), AMR and/or its subsidiaries will make all minimum required contributions to each AMR compensation and benefit plan that are required to have been made and were not made prior to the effective date of the Merger. As a result of the Company only contributing the post-petition portion of required contributions, the PBGC filed a lien against certain assets of the Company in 2012.

Recent Modifications to Pension and Other Post-Employment Benefits

The Company's defined benefit pension plans were frozen effective November 1, 2012. Eligible employees began to receive a replacement benefit under the $uper $aver 401(k) Plan on November 1, 2012.

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 approving 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. Plan B assets will be distributed to pilots in mid-2013.

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 and initiated retiree medical coverage before November 1, 2012. 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. Those negotiations are continuing.

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. See Note 1 to the Condensed Consolidated Financial Statements for the breakout of liabilities subject to compromise, including that related to pension and postretirement benefits.

Financial Instruments And Risk Management

3 Months Ended

Mar. 31, 2013

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Financial Instruments And Risk Management

Financial Instruments and Risk Management

As part of the Company’s risk management program, it uses a variety of financial instruments, primarily heating oil, jet fuel, and Brent crude collars (consisting of a purchased call option and a sold put option) and call spreads (consisting of a purchased call option and a sold call option), as cash flow hedges to mitigate commodity price risk. The Company does not hold or issue derivative financial instruments for trading purposes. As of March 31, 2013, the Company had fuel derivative contracts outstanding covering 19 million barrels of jet fuel that will be settled over the next 18 months. A deterioration of the Company’s liquidity position and its Chapter 11 filing may negatively affect the Company’s ability to hedge fuel in the future.

For the three months ended March 31, 2013 and March 31, 2012, the Company recognized a decrease of approximately $8 million and $29 million, respectively, in 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 March 31, 2013 and December 31, 2012, representing the amount the Company would receive upon termination of the agreements (net of settled contract assets), totaled $61 million and $62 million, respectively. As of March 31, 2013, the Company estimates that during the next twelve months it will reclassify from Accumulated other comprehensive loss into earnings approximately $1 million in net gains.

The impact of cash flow hedges on the Company’s Condensed Consolidated Financial Statements is depicted below (in millions):

The Company is party to certain interest rate swap agreements that are accounted for as cash flow hedges. Ineffectiveness for these instruments is required to be measured at each reporting period. The ineffectiveness and fair value associated with all of the Company's interest rate cash flow hedges for all periods presented was not material.

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 Condensed Consolidated Balance Sheets. Certain of these agreements would also allow for the offsetting of fuel derivatives with interest rate derivatives. The impact of offsetting derivative instruments is depicted below (in millions):

As of March 31, 2013:



							Gross asset (liability) not offset in Balance Sheet
	Gross asset (liability)		Gross asset (liability) offset in Balance Sheet		Net recognized asset (liability) in Balance Sheet		Financial Instruments		Cash Collateral Received (Posted)		Net Amount
Fuel derivatives	$	66	$	—	$	66	$	—	$	—	$	66

As of December 31, 2012:



							Gross asset (liability) not offset in Balance Sheet
	Gross asset (liability)		Gross asset (liability) offset in Balance Sheet		Net recognized asset (liability) in Balance Sheet		Financial Instruments		Cash Collateral Received (Posted)		Net Amount
Fuel derivatives	$	65	$	—	$	65	$	—	$	—	$	65

As of March 31, 2013, the Company had posted cash collateral of an immaterial amount.

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 its 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 exceed specified mark-to-market thresholds or upon certain changes in credit ratings.

- Definition

The entire disclosure for the entity's entire derivative instruments and hedging activities. Describes an entity's risk management strategies, derivatives in hedging activities and non-hedging derivative instruments, the assets, obligations, liabilities, revenues and expenses arising therefrom, and the amounts of and methodologies and assumptions used in determining the amounts of such items.

Merger Agreement

3 Months Ended

Mar. 31, 2013

Business Combinations [Abstract]

Business Combination Disclosure [Text Block]

12. Merger Agreement

Description of Agreement and Plan of Merger

On February 13, 2013, AMR, US Airways Group, Inc., a Delaware corporation (US Airways Group), and AMR Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of AMR (Merger Sub), entered into an Agreement and Plan of Merger (the Merger Agreement), providing for a business combination of AMR and US Airways Group. The Merger Agreement provides that, upon the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into US Airways Group (the Merger), with US Airways Group surviving as a wholly owned subsidiary of AMR. AMR and US Airways Group anticipate that immediately following the merger closing, AMR will change its name to American Airlines Group Inc. (AAG). Following the Merger, AAG will own, directly or indirectly, all of the equity interests of American, US Airways Group and their direct and indirect subsidiaries. The Merger Agreement and the transactions contemplated thereby, including the Merger, are subject to the approval of the Bankruptcy Court, and are to be effected pursuant to a plan of reorganization (the Plan) of the Debtors in connection with the Chapter 11 Cases. The Plan was filed on April 15, 2013, and is subject to confirmation and consummation in accordance with the requirements of the Bankruptcy Code.

Subject to the terms and conditions of the Merger Agreement, which has been approved by the boards of directors of the respective parties, upon completion of the Merger, US Airways Group stockholders will receive one share of common stock of AAG (AAG Common Stock) for each share of US Airways Group common stock. The aggregate number of shares of AAG Common Stock issuable to holders of US Airways Group equity instruments (including stockholders and holders of convertible notes, options, stock appreciation rights and restricted stock units) will represent 28% of the diluted capitalization of AAG after giving effect to the Plan. The remaining 72% diluted equity ownership of AAG will be distributable, pursuant to the Plan, to the Debtors' stakeholders, labor unions and certain employees.

All of the equity interests in AAG will be issued solely pursuant to the Merger Agreement or the Plan. Pursuant to the proposed Plan filed with the Bankruptcy Court on April 15, 2013, holders of AMR equity interests are expected to receive a recovery on such interests in the form of a distribution of AAG common stock. Implementation of the Plan and the making of any distributions thereunder are subject to confirmation thereof in accordance with the provisions of the Bankruptcy Code, the occurrence of the effective date under the Plan and the consummation of the Merger.

The Merger is intended to qualify, for federal income tax purposes, as a reorganization under the provisions of Section 368(a) of the Internal Revenue Code of 1986, as amended.

The Merger Agreement provides that, upon consummation of the Merger, the board of directors of the combined company will initially consist of 12 members, composed of (i) Thomas W. Horton, AMR's current chairman, chief executive officer and president, who will serve as chairman of AAG until the earlier of (A) one year after the closing of the Merger and (B) the day immediately prior to the first annual meeting of stockholders of the combined company (provided that such meeting will not occur prior to May 1, 2014), (ii) W. Douglas Parker, US Airways Group current chief executive officer, who will serve as chief executive officer of AAG and will serve as chairman of AAG following the end of Mr. Horton's term, (iii) two independent directors designated by AMR, (iv) three independent directors designated by US Airways Group, and (iv) five independent directors designated by a search committee consisting of representatives of the Creditors' Committee and certain representatives of creditors signatory to the support agreement with AMR referred to below. One of such independent directors will serve as lead independent director. Subject to applicable law, prior to the Merger, senior executives from each of AMR and US Airways Group will engage in a planning process for integration purposes.

AMR and US Airways Group have each made customary representations, warranties and covenants in the Merger Agreement, including, among others, covenants to conduct their businesses in the ordinary and usual course between the execution of the Merger Agreement and the consummation of the Merger, subject to certain restrictions as set forth in the Merger Agreement. In addition, the Merger Agreement contains “no shop” provisions that restrict each party's ability to initiate, solicit or knowingly encourage or facilitate competing third-party proposals for any transaction involving a merger of such party or the acquisition of a significant portion of its stock or assets, although each party may consider competing, unsolicited proposals and enter into discussions or negotiations regarding such proposals, if its board of directors determines that any such acquisition proposal constitutes, or is reasonably likely to lead to, a superior proposal and that the failure to take such action is reasonably likely to be inconsistent with its fiduciary duties under applicable law.

US Airways Group has agreed to certain additional customary covenants in the Merger Agreement, including, among others, subject to certain exceptions, (i) to cause a stockholder meeting to be held to consider adoption of the Merger Agreement and (ii) for its board of directors to recommend adoption of the Merger Agreement by US Airways Group stockholders. AMR has also agreed to certain additional customary covenants in the Merger Agreement, including, among others, subject to certain exceptions, (i) to pursue confirmation of the Plan and (ii) for its board of directors to recommend adoption of the Merger Agreement by the Debtors' stakeholders.

Consummation of the Merger is subject to customary conditions, including, among others: (i) approval by the stockholders of US Airways Group; (ii) expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the receipt of certain other regulatory approvals; (iii) absence of any order or injunction prohibiting the consummation of the Merger; (iv) Bankruptcy Court confirmation of the Plan, which must contain certain specified provisions defined in the Merger Agreement; (v) subject to certain exceptions, the accuracy of representations and warranties with respect to the business of AMR or US Airways Group, as applicable; (vi) each of AMR and US Airways Group having performed their respective obligations pursuant to the Merger Agreement; and (vii) receipt by each of the Company and US Airways Group of a customary tax opinion.

The Merger Agreement contains certain termination rights for AMR and US Airways Group, and further provides that, upon termination of the Merger Agreement under specified circumstances, (i) AMR may be required to pay US Airways Group a termination fee of $135 million in the event it terminates the agreement to enter into a superior proposal and $195 million if US Airways Group terminates the Merger Agreement in the event of a knowing and deliberate breach of the Merger Agreement by AMR and (ii) US Airways Group may be required to pay AMR a termination fee of $55 million in the event it terminates the agreement to enter into a superior proposal and $195 million if AMR terminates the Merger Agreement in the event of a knowing and deliberate breach of the Merger Agreement by US Airways Group.

On February 22, 2013, the Debtors filed a motion for entry of the Merger Support Order, which is defined as an order of the Bankruptcy Court approving the Merger Agreement and certain related matters contemplated thereby in the form required by the Merger Agreement. The Bankruptcy Court conducted a hearing on the Debtors' motion on March 27, 2013. As of April 16, 2013, the Bankruptcy Court has not entered the Merger Support Order in the form required by the Merger Agreement. If the Merger Support Order is not entered on or before May 14, 2013, the Merger Agreement may be terminated in accordance with its termination provisions. Unless and until the Merger Support Order is entered, the Merger Agreement is not binding on or enforceable against AMR, US Airways Group or AMR Merger Sub. Based on the Bankruptcy Court hearing on March 27, 2013 to consider the Merger Support Motion and any related objections and the memorandum of decision issued by the Bankruptcy Court on April 11, 2013, AMR and US Airways Group anticipate that the Bankruptcy Court will enter an order that fails to meet all of the requirements of the Merger Agreement. AMR and US Airways Group are discussing how to address this anticipated issue.

Support Agreement and Term Sheet

On February 13, 2013, AMR and the other Debtors entered into a Support and Settlement Agreement (the Support Agreement) with certain significant holders of certain prepetition claims against one or more of the Debtors (such holders of claims, the Consenting Creditors), aggregating approximately $1.2 billion of prepetition unsecured claims. Pursuant to the terms of the Support Agreement, each Consenting Creditor has agreed, among other things, and subject to certain conditions, to (a) vote in favor of a Plan, which must include certain terms specified in a Term Sheet attached to the Support Agreement (the Term Sheet), (b) generally support confirmation and consummation of the Plan and (c) not to support or solicit any plan in opposition to the Plan. Confirmation and consummation of the Plan are subject to compliance with the provisions of the Bankruptcy Code and to the closing of the Merger.

The Support Agreement may be terminated upon the occurrence of certain events, including: (a) certain breaches by the Debtors or Consenting Creditors under the Support Agreement; (b) termination of the Merger Agreement or the announcement by AMR or US Airways Group of their intent to terminate the Merger Agreement (in which case the Support Agreement would terminate automatically); (c) the failure to meet certain milestones with respect to achieving confirmation and consummation of the Plan; (d) the filing, amendment or modification of certain documents, including the Plan, in a manner materially inconsistent with the Support Agreement and materially adverse to a Consenting Creditor (in which case the Support Agreement can be terminated by such Consenting Creditor solely with respect to itself); (e) the amendment or modification of the Merger Agreement in a manner that is materially adverse to a Consenting Creditor (in which case the Support Agreement can be terminated by such Consenting Creditor solely with respect to itself); and (f) if the volume weighted average price of US Airways Group common stock for the thirty trading days ending on the last trading day immediately prior to the date of termination is less than $10.40. Termination of the Support Agreement would give the Consenting Creditors the right to withdraw their support of the Plan.

As described in the Term Sheet, the Plan implements the Merger, incorporates a compromise and settlement of certain intercreditor and intercompany claim issues, and is to contain the following provisions relating to the treatment of prepetition unsecured claims against the Debtors and equity interests in AMR:

•

Unless they elect to receive alternative treatment, holders of prepetition unsecured claims against AMR or American that also are guaranteed by either such company (Double-Dip Unsecured Claims) will receive shares of preferred stock of AAG (the AAG Preferred Stock) that will be mandatorily convertible into shares of AAG Common Stock on each of the 30th, 60th, 90th and 120th day after the effective date of the Plan. Upon the conversion of the remaining AAG Preferred Stock on the 120th day after the effective date of the Plan, all AAG Preferred Stock will have been converted to AAG Common Stock and no AAG Preferred Stock will remain outstanding. The conversion price of the AAG Preferred Stock will vary on each conversion date, based on the volume weighted average price of the shares of the AAG Common Stock on the five trading days immediately preceding each conversion date, at a 3.5% discount, subject to a cap and a floor price. The AAG Preferred Stock allocable to the Double-Dip Unsecured Claims will have a face amount equal to the allowed amount of their claims, including post-petition interest at the non-default rate;


•	Holders of prepetition unsecured claims (other than claims of the Debtors' unions) that are not Double-Dip Unsecured Claims (and holders of Double-Dip Unsecured Claims that elect to receive such treatment) will receive shares of AAG Preferred Stock, as well as shares of AAG Common Stock;


•	Holders of existing AMR equity interests (including stock, warrants, restricted stock units and options) will receive a distribution of shares of AAG Common Stock representing 3.5% of the total number of shares of AAG Common Stock (on an as-converted basis) in addition to the potential to receive shares of AAG Common Stock above such amount; and


•	The satisfaction of certain labor-related claims through the allocation to such claims of shares of AAG Common Stock representing 23.6% of the total number of such shares of AAG Common Stock ultimately distributed to holders of prepetition general unsecured claims against the Debtors.

In each case, the distributions made to each of the foregoing stakeholders will be adjusted to take into account any reserves made for disputed claims under the Plan. The Debtors have filed a motion with the Bankruptcy Court seeking approval of the Support Agreement.

- Definition

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

Subsequent Events	Mar. 31, 2013
Subsequent Events [Abstract]
Subsequent Events [Text Block]	Subsequent Events Filing of Plan of Reorganization, Disclosure Statement and Form S-4 On April 15, 2013, the Company and other Debtors filed with the Bankruptcy Court the Plan of Reorganization (the Plan) and a related Disclosure Statement (the Disclosure Statement), which contemplate that AMR will emerge from Chapter 11 and merge with US Airways Group (as further described in Note 12 to the Condensed Consolidated Financial Statements). The Plan addresses various subjects with respect to the Debtors, including the resolution of pre-petition obligations as well as the capital structure and corporate governance after exit from the Chapter 11 Cases. The Plan further provides that, upon the effectiveness of the Plan and the Merger, which are anticipated to occur contemporaneously, all shares of existing AMR common stock and other equity interests in AMR will be cancelled and any rights with respect thereto will cease to exist. Generally, for purposes of the Plan, all 20 Debtors will be “substantively consolidated” into three nodes, consisting of: (i) AMR Debtors, (ii) American Debtors, and (iii) Eagle Debtors. As among the AMR Debtors, the American Debtors, and the Eagle Debtors, the Plan will separately classify creditor claims. However, pursuant to the compromises incorporated into the Plan relating to certain inter-creditor issues and the treatment of intercompany claims among the Debtors, general unsecured claims of similar rank and priority will be treated the same under the Plan regardless of the Debtor against which such claim was filed. The Plan contains provisions related to the treatment of prepetition unsecured claims against the Debtors and equity interests in AMR as described in Note 13 to the Condensed Consolidated Financial Statements under "Support Agreement and Term Sheet." On April 15, 2013, the Company also filed a Form S-4 registration statement with the Securities and Exchange Commission (the SEC) to register the shares of AAG Common Stock that will be issued to stockholders of US Airways Group as consideration in the Merger in exchange for their US Airways Group common stock. The AAG Common Stock cannot be issued to US Airways Group stockholders until the SEC declares the registration statement to be effective. The Company and other Debtors have until July 29, 2013 to solicit and obtain acceptances for the Plan. To be accepted by holders of claims against the Debtors, the Plan must be approved by at least one-half in number and two-thirds in dollar amount of claims actually voting in each impaired class. Under certain circumstances set forth in Section 1129(b) of the Bankruptcy Code, the Bankruptcy Court may confirm a plan even if such plan has not been accepted by all impaired classes of claims and equity interests. A class of claims or equity interests that does not receive or retain any property under the plan on account of such claims or interests is deemed to have voted to reject the plan. The precise requirements and evidentiary showing for confirming a plan notwithstanding its rejection by one or more impaired classes of claims or equity interests depends upon a number of factors, including the status and seniority of the claims or equity interests in the rejecting class (i.e., secured claims or unsecured claims, subordinated or senior claims, preferred or common stock). The information contained in the Disclosure Statement is subject to change, whether as a result of amendments to the Plan of Reorganization, actions of third parties or otherwise. Nothing contained in this Form 10-Q is intended to be, nor should it be construed as, a solicitation for a vote on the Plan. The Plan will become effective only if it receives the requisite approval and is confirmed by the Bankruptcy Court. There can be no assurance that the Bankruptcy Court will confirm the Plan of Reorganization or that any such plan will be implemented successfully. Other On April 3, 2013, the Bankruptcy Court entered an order approving a stipulation providing that, among other things, (i) the 1990 and 1994 series of special facility revenue bonds that financed certain improvements at John F. Kennedy International Airport (JFK) will be treated as general unsecured claims, (ii) the Debtors may continue to use any premises and improvements at JFK or LaGuardia Airport financed by the 1990 or 1994 series of special facility revenue bonds, (iii) the Debtors will assume the leases at JFK that currently relate to the 2002 and 2005 series of special facility revenue bonds, and (iv) the Debtors' use of premises at JFK will continue to be governed by those leases as well as any other leases that may apply (including leases with the Port Authority of New York and New Jersey). As a result, the Company expects a claim of $171 million, of which $124 million has been previously accrued, plus post-petition interest.

- Definition

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item represents Available-for-sale Securities which consist of all investments in certain debt and equity securities neither classified as trading or held-to-maturity securities. A debt security represents a creditor relationship with an enterprise. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt. An entity may opt to provide the reader with additional narrative text to better understand the nature of investments in debt and equity securities which are categorized as Available-for-sale.
