Reorganization [Abstract]

Reorganization

1. Chapter 11 Reorganization

Overview

As previously discussed, on November 29, 2011, AMR and certain of its direct and indirect domestic subsidiaries filed voluntary petitions for relief under the Bankruptcy Code in the United States Bankruptcy Court for the Southern District of New York. 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. Moreover, the Debtors have not yet prepared or filed with the Bankruptcy Court a plan of reorganization. The ultimate plan of reorganization, which would be subject to acceptance by the requisite majorities of empowered creditors under the Bankruptcy Code and approved by the Bankruptcy Court, could materially change the amounts and classifications in the historical Condensed Consolidated Financial Statements.

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.

No assurance can be given as to the value, if any, that may be ascribed to the Debtors' various pre-petition liabilities and other securities. The Company cannot predict what the ultimate value of any of its securities may be and it remains too early to determine whether holders of any such securities will receive any distribution in the Debtors' reorganization. In particular, in most cases under Chapter 11 of the Bankruptcy Code, holders of equity securities receive little or no recovery of value from their investment. Accordingly, the Debtors urge that caution be exercised with respect to existing and future investments in any of these securities or other Debtor claims. In addition, trading in the Company's common stock and certain debt securities on the NYSE was suspended on January 5, 2012, and the Company's common stock and such debt securities were delisted by the Securities and Exchange Commission from the NYSE on January 30, 2012. On January 5, 2012, the Company's common stock began trading under the symbol "AAMRQ" on the OTCQB marketplace, operated by OTC Markets Group (www.otcmarkets.com).

General Information

Notices to Creditors; Effect of Automatic Stay. The Debtors have begun the process of seeking to notify all known current or potential creditors that the Chapter 11 Cases had been 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 for the Southern District of New York, a unit of the Department of Justice, appointed a statutory official committee of unsecured creditors for the Chapter 11 Cases. The Bankruptcy Code provides for the U.S. Trustee to appoint a statutory committee of creditors holding unsecured claims as soon as practicable after the commencement of a Chapter 11 case. The statutory creditors' committee ordinarily consists of holders of the seven largest unsecured claims who are willing to serve. A statutory creditors' committee represents the interests of all unsecured creditors in a bankruptcy case.

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. Under the Bankruptcy Code, the Debtors' rights to assume, assume and assign, or reject unexpired leases of non-residential real estate expire on March 27, 2012 (subject to further extension by the Bankruptcy Court but not to exceed 210 days from the Petition Date). 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 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.

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 any of 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. While the Debtors have reached agreements on, or agreements on key aspects of, renegotiated terms with respect to certain of their Aircraft Properties and are continuing to negotiate terms with respect to many of their other Aircraft Property financings, 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.

In accordance with Section 1110 of the Bankruptcy Code, as of December 31, 2011, the Company had rejected 24 aircraft leases relating to 20 MD-80 aircraft and four Fokker 100 aircraft. In addition, since December 31, 2011, the Company has rejected an additional 9 aircraft leases and mortgages relating to one MD-80 aircraft, seven Boeing 757-200 aircraft, and one Airbus A300-600R aircraft. In addition, the Company filed a motion with the Bankruptcy Court to modify the leases of the Super ATR aircraft. As of February 15, 2012, 21 of the aircraft had been returned to the lessor as allowed under the modified agreement. The remaining 18 aircraft will be returned to the lessor during 2012 and 2013. In January 2012, American entered into agreements under Section 1110(a) of the Bankruptcy Code to retain 350 aircraft, including Boeing 737-800, Boeing 757-200, Boeing 767-300ER, Boeing 777-200ER, Bombardier CRJ-700, and McDonnell Douglas MD-80 aircraft on the terms provided in the related financing documents.

Magnitude of Potential Claims The Debtors will file 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. The Bankruptcy Court has not yet established a date and time by which such proofs of claim must be filed.

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. The Bankruptcy Code provides a process for the modification and/or rejection of collective bargaining agreements (CBAs). In particular, Section 1113(c) of the Code permits a debtor to reject its CBAs if the debtor satisfies a number of statutorily prescribed substantive and procedural prerequisites and obtains the Bankruptcy Court's approval to reject the CBAs. The 1113(c) process requires that a debtor must make proposals to its unions to modify existing CBAs based on the most complete and reliable information available at the time the proposals are made. The proposed modifications must be necessary to permit the reorganization of the debtor and must assure that all the affected parties are treated fairly and equitably. The debtor must provide the unions with all information necessary to evaluate the proposals, and meet at reasonable times and confer in good faith with the unions in an effort to reach mutually agreeable modifications to the CBAs. If consensual agreements are not reached, the debtor may file a motion with the Bankruptcy Court requesting approval to reject the CBAs. Rejection of the CBAs is appropriate if the Court finds the debtor's proposals are necessary for its reorganization, are fair and equitable, and that the unions refused to agree to the proposals without good cause. American commenced the Section 1113(c) process with its unions on February 1, 2012. AMR Eagle intends to commence the Section 1113(c) process with its unions soon.

Plan of reorganization. The Debtors have the exclusive right for 120 days after the Petition Date to file a plan of reorganization and, if they do so, 60 additional days to obtain necessary acceptances of the plan. The Debtors exclusivity period may be extended by the Court, with good cause, for up to 18 months from the Petition Date. If the Debtors' exclusivity period lapses, any party in interest may file a plan of reorganization for any of the Debtors. In addition to being voted on by holders of impaired claims and equity interests, a plan of reorganization must satisfy certain requirements of the Bankruptcy Code and must be approved, or confirmed, by the Bankruptcy Court in order to become effective. A plan of reorganization has been accepted by holders of claims against and equity interests in the Debtors if (1) at least one-half in number and two-thirds in dollar amount of claims actually voting in each impaired class of claims have voted to accept the plan and (2) at least two-thirds in amount of equity interests actually voting in each impaired class of equity interests has voted to accept the plan.

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). Generally, with respect to common stock interests, a plan may be "crammed down" even if the shareowners receive no recovery if the proponent of the plan demonstrates that (1) no class junior to the common stock is receiving or retaining property under the plan and (2) no class of claims or interests senior to the common stock is being paid more than in full.

The availability and utilization of net operating losses (and utilization of AMT credits) post-emergence is uncertain at this time and will be highly influenced by the composition of restructuring plan alternatives that may be considered and 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 (Docket No. 890], which restricts trading in the Company's common stock and claims.

Liabilities Subject to Compromise

The following table summarizes the components of liabilities subject to compromise included on the Consolidated Balance Sheet as of December 31, 2011:


(in millions)

Long-term debt	$	2,482
Aircraft lease and facility bond related obligations		1,868
Accounts payable and other accrued liabilities		489
Accrued interest on long-term debt and unamortized debt issuance costs		4

Total liabilities subject to compromise	$	4,843

Long-term debt, including undersecured debt, classified as subject to compromise as of December 31, 2011 consisted of (in millions):


Secured variable and fixed rate indebtedness due through 2023 (effective rates from 1.00% - 13.00% at December 31, 2011)	$	1,456
6.00% - 8.50% special facility revenue bonds due through 2036		186
6.25% senior convertible notes due 2014		460
9.0% - 10.20% debentures due through 2021		214
7.88% - 10.55% notes due through 2039		166

	$	2,482

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.

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 proceedings 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 as a direct result of the Chapter 11 proceedings.

Summary Of Accounting Policies [Abstract]

Summary Of Accounting Policies

2. Summary of Accounting Policies

Basis of Presentation The accompanying consolidated financial statements as of December 31, 2011 and for the three years ended December 31, 2011 include the accounts of AMR and its wholly owned subsidiaries, including (i) its principal subsidiary, American Airlines, Inc. (American) and (ii) its regional airline subsidiary, AMR Eagle Holding Corporation and its primary subsidiaries, American Eagle Airlines, Inc. and Executive Airlines, Inc. (collectively, AMR Eagle). The consolidated financial statements as of and for the years ended December 31, 2011, 2010 and 2009 include the accounts of the Company and its wholly owned subsidiaries as well as VIEs for which the Company is the primary beneficiary. All significant intercompany transactions have been eliminated.

The accompanying Consolidated Financial Statements have been prepared in accordance with United States (U.S.) generally accepted accounting principles (GAAP), including the provisions of ASC 852 "Reorganizations" (ASC 852). 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 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 the Debtors in accordance with the requirements of reorganization accounting.

These 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 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 proceedings, 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 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 2). 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; (3) as to shareowners' equity accounts, the effect of any changes that may be made to the Debtors' capitalization; or (4) as to operations, the effect of any changes that may be made to the Debtors' business.

New Accounting Pronouncements In November of 2009, the Financial Accounting Standards Board (FASB) issued new guidance that significantly changes the accounting for revenue in arrangements with multiple deliverables by requiring entities to separately account for individual deliverables in more of these arrangements and estimate the fair value of each component individually on a pro-rata basis. The guidance no longer provides use of the residual method, but rather requires an estimate of fair value based on vendor-specific objective evidence (VSOE), third party evidence, or estimated selling price. The standard must be applied prospectively to revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. In addition, the FASB significantly expanded the disclosures related to multiple deliverable revenue arrangements. The impact of adoption was not material in 2011, but could have a significant impact on future results as new or materially modified revenue arrangements with certain partners are established in the normal course of business.

In June of 2011, the FASB issued new guidance revising the manner in which entities present comprehensive income in their financial statements. The new guidance requires entities to report components of comprehensive income in either (1) a continuous statement of comprehensive income or (2) two separate but consecutive statements. Under the two-statement approach, the first statement would include components of net income, which is consistent with the income statement format used today, and the second statement would include components of OCI. Items that must be reported in OCI do not change. For public entities, the guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. Guidance must be applied retrospectively for all periods presented in the financial statements. Early adoption is permitted, and as such the Company elected to early adopt this guidance for the fiscal year ended December 31, 2011.

Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the accompanying consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Restricted Cash and Short-term Investments The Company has restricted cash and short-term investments related primarily to collateral held to support projected workers' compensation obligations and funds held for certain tax obligations.

Inventories Spare parts, materials and supplies relating to flight equipment are carried at average acquisition cost and are expensed when used in operations. Allowances for obsolescence are provided—over the estimated useful life of the related aircraft and engines—for spare parts expected to be on hand at the date aircraft are retired from service. Allowances are also provided for spare parts currently identified as excess and obsolete. These allowances are based on management estimates, which are subject to change.

Maintenance and Repair Costs Maintenance and repair costs for owned and leased flight equipment are charged to operating expense as incurred, except costs incurred for maintenance and repair under flight hour maintenance contract agreements, which are accrued based on contractual terms when an obligation exists.

Intangible Assets Route acquisition costs and airport operating and gate lease rights represent the purchase price attributable to route authorities (including international airport take-off and landing slots), domestic airport take-off and landing slots and airport gate leasehold rights acquired. Indefinite-lived intangible assets (route acquisition costs and international slots and related international take-off and landing slots) are tested for impairment annually on December 31, rather than amortized, or when a triggering event occurs, in accordance with U.S. GAAP. Such triggering events may include significant changes to the Company's network or capacity, or the implementation of open skies agreements in countries where the Company operates flights. Airport operating and gate lease rights are being amortized on a straight-line basis over 25 years to a zero residual value.

Statements of Cash Flows Short-term investments, without regard to remaining maturity at acquisition, are not considered as cash equivalents for purposes of the statements of cash flows.

Measurement of Asset Impairments The Company records impairment charges on long-lived assets used in operations when events and circumstances indicate that the assets may be impaired. An asset or group of assets is considered impaired when the undiscounted cash flows estimated to be generated by the asset are less than the carrying amount of the asset and the net book value of the asset exceeds its estimated fair value. In making these determinations, the Company uses certain assumptions, including, but not limited to: (i) estimated fair value of the asset; and (ii) estimated future cash flows expected to be generated by the asset, which are based on additional assumptions such as asset utilization, length of service the asset will be used in the Company's operations and estimated salvage values.

Equipment and Property The provision for depreciation of operating equipment and property is computed on the straight-line method applied to each unit of property, except that major rotable parts, avionics and assemblies are depreciated on a group basis. The depreciable lives used for the principal depreciable asset classifications are:


		Depreciable Life

American jet aircraft and engines		20- 30 years
Other regional aircraft and engines		16- 20 years
Major rotable parts, avionics and assemblies		Life of equipment to which applicable
Improvements to leased flight equipment		Lesser of remaining lease term or expected useful life
Buildings and improvements (principally on leased land)		5- 30 years or term of lease, including estimated renewal options when renewal is economically compelled at key airports
Furniture, fixtures and other equipment		3 - 10 years
Capitalized software		5- 10 years

Residual values for aircraft, engines, major rotable parts, avionics and assemblies are generally five to ten percent, except when guaranteed by a third party for a different amount.

Equipment and property under capital leases are amortized over the term of the leases or, in the case of certain aircraft, over their expected useful lives. Lease terms vary but are generally six to 25 years for aircraft and seven to 40 years for other leased equipment and property.

Regional Affiliates Revenue from ticket sales is generally recognized when service is provided. Regional Affiliates revenues for flights connecting to American flights are based on industry standard proration agreements.

Passenger Revenue Passenger ticket sales are initially recorded as a component of Air traffic liability. Revenue derived from ticket sales is recognized at the time service is provided. However, due to various factors, including the complex pricing structure and interline agreements throughout the industry, certain amounts are recognized in revenue using estimates regarding both the timing of the revenue recognition and the amount of revenue to be recognized, including breakage. These estimates are generally based upon the evaluation of historical trends, including the use of regression analysis and other methods to model the outcome of future events based on the Company's historical experience, and are recorded at the scheduled time of departure.

Various taxes and fees assessed on the sale of tickets to end customers are collected by the Company as an agent and remitted to taxing authorities. These taxes and fees have been presented on a net basis in the accompanying consolidated statement of operations and recorded as a liability until remitted to the appropriate taxing authority.

Frequent Flyer Program The estimated incremental cost of providing free travel awards is accrued for mileage credits earned by using American's service that are expected to be redeemed in the future. American also accrues a frequent flyer liability for the mileage credits that are expected to be used for travel on participating airlines based on historical usage patterns and contractual rates. American sells mileage credits and related services to companies participating in its frequent flyer program. The portion of the revenue related to the sale of mileage credits, representing the revenue for air transportation sold, is valued at fair value and is deferred and amortized over 28 months, which approximates the expected period over which the mileage credits are used. Breakage of sold miles is recognized over the estimated period of usage. The remaining portion of the revenue, representing the marketing services sold and administrative costs associated with operating the AAdvantage program, is recognized upon sale as a component of Other revenues, as the related services have been provided. The Company's total liability for future AAdvantage award redemptions for free, discounted or upgraded travel on American, American Eagle or participating airlines as well as unrecognized revenue from selling AAdvantage miles was approximately $1.6 billion (and is recorded as a component of Air traffic liability on the accompanying consolidated balance sheets) at December 31, 2011 and $1.4 billion as ofDecember 31, 2010.

Income Taxes The Company generally believes that the positions taken on previously filed income tax returns are more likely than not to be sustained by the taxing authorities. The Company has recorded income tax and related interest liabilities where the Company believes its position may not be sustained or where the full income tax benefit will not be recognized. Thus, the effects of potential income tax benefits resulting from the Company's unrecognized tax positions are not reflected in the tax balances of the financial statements. Recognized and unrecognized tax positions are reviewed and adjusted as events occur that affect the Company's judgment about the recognizability of income tax benefits, such as lapsing of applicable statutes of limitations, conclusion of tax audits, release of administrative guidance, or rendering of a court decision affecting a particular tax position.

Advertising Costs The Company expenses on a straight-line basis the costs of advertising as incurred throughout the year. Advertising expense was $186 million for the year ended December 31, 2011, $165 million for the year ended December 31, 2010 and $153 million for the year ended December 31, 2009.

Subsequent Events In connection with preparation of the consolidated financial statements and in accordance U.S. GAAP, the Company evaluated subsequent events after the balance sheet date of December 31, 2011 and identified items as set forth in Note 18 to the consolidated financial statements.

Special Charges And Restructuring Activities

3. Special Charges and Restructuring Activities

Current Year As previously announced, American entered into agreements with Airbus and Boeing in the second quarter of 2011 under which it plans to acquire 460 narrowbody aircraft from the Boeing 737 and Airbus A320 families during the period 2013-2022. The Bankruptcy Court has not approved American's assumption of the Boeing and Airbus contracts, but has approved certain procedures to allow American to continue taking delivery of Boeing 737 and Boeing 777 aircraft for the remainder of 2012, subject to objection by the Creditors' Committee, and subject to certain limitations. In connection with these Boeing and Airbus aircraft agreements and the Company's anticipated acceleration of its fleet renewal and replacement plan, the Company evaluated the useful lives of certain fleets including McDonnell Douglas MD-80, Boeing 757 and Boeing 767 aircraft. Upon finalization of the fleet plan in the fourth quarter of 2011 (prior to the filing of the Chapter 11 Cases), the Company concluded that a triggering event had occurred, requiring that certain assets be tested for impairment. As a result of this test, the Company concluded the carrying value of Boeing 757 aircraft used in its domestic markets was no longer recoverable. Consequently, the 2011 results include an impairment charge of $713 million to write these and certain related long-lived assets down to their estimated fair values. The impairment charge is non-cash. The impaired B757 aircraft are being depreciated over their remaining useful lives averaging approximately 4 years.

In determining the asset recoverability, management estimated the undiscounted future cash flows utilizing models used by the Company in making fleet and scheduling decisions. In determining fair market value, the Company utilized recent external appraisals of its fleets and two published aircraft pricing surveys, adjusted based on estimates of maintenance status and to consider the impact of recent industry events on these values. As a result of the write down of these aircraft to fair value, as well as the acceleration of the retirement dates, depreciation expense related to these assets is expected to decrease by approximately $24 million in 2012.

Prior Years As a result of the revenue environment, high fuel prices and the Company's restructuring activities, including its capacity reductions, the Company recorded a number of charges during the last few years. In 2008 and 2009, the Company announced capacity reductions due to unprecedented high fuel costs at that time and the other challenges facing the industry. In connection with these capacity reductions, the Company incurred special charges related to aircraft, people reductions and certain other charges.

Aircraft Charges

As part of these capacity reductions, the Company grounded its leased Airbus A300 aircraft prior to lease expiration. In 2009, the Company incurred approximately $94 million in net present value of future lease payments and lease return costs related to the grounding of the leased Airbus A300 fleet. The Company estimates that virtually all of these charges will result in future cash expenditures. Further, the Company also wrote down its owned Airbus A300 aircraft and related inventory to estimated salvage value in the fourth quarter of 2009, resulting in a non-cash expense of $20 million. All Airbus A300 aircraft were permanently retired as of 2009.

In the fourth quarter of 2009, due to the continuing severe downturn in the global economy and weakness in the regional jet aircraft market, the Company's plan to sell certain of its Embraer RJ-135 aircraft was no longer feasible at the amount for which these aircraft had been valued. Consequently, the Company reclassified these aircraft from held for sale to held for use, tested them for impairment and concluded the carrying values of certain of its Embraer RJ-135 aircraft were no longer recoverable. Therefore, during the fourth quarter of 2009, the Company recorded an impairment charge of $42 million to write these aircraft down to their estimated fair values. In addition, these aircraft will now resume depreciation prospectively. In determining the fair values of these aircraft, the Company considered recent transactions for sales of similar aircraft and the value of the underlying engines. No portion of the impairment charge will result in future cash expenditures.

Employee Charges

In conjunction with the capacity reductions announced in 2008, the Company reduced its workforce commensurate with the announced system-wide capacity reductions. This reduction in workforce was accomplished through various measures, including voluntary programs, part-time work schedules, furloughs in accordance with collective bargaining agreements, and other reductions.

The following table summarizes the components of the Company's special charges, the remaining accruals for these charges and the capacity reduction related charges (in millions) as of December 31, 2011:


	Aircraft Charges			Facility Exit Costs			Employee Charges			Total
Remaining accrual at January 1, 2009	$	110		$	16		$	16		$	142

Payments		(36	)		(4	)		-			(40	)

Remaining accrual at December 31, 2011	$	49		$	16		$	-		$	65

Cash outlays related to the accruals for aircraft charges and facility exit costs will occur through 2017 and 2018, respectively. However, these cash outlays could be modified in the Chapter 11 proceedings.

Other

On September 22, 2001, the Air Transportation Safety and System Stabilization Act (the Stabilization Act) was signed into law. The Stabilization Act provides that, notwithstanding any other provision of law, liability for all claims, whether compensatory or punitive, arising from the Terrorist Attacks, against any air carrier shall not exceed the liability coverage maintained by the air carrier. Based upon estimates provided by the Company's insurance providers, the Company initially recorded a liability of approximately $2.3 billion for claims arising from the Terrorist Attacks, after considering the liability protections provided for by the Stabilization Act. In the second quarter of 2011, the Company received $576 million in insurance proceeds as partial settlement of claims related to the Terrorist Attacks. The Company used these funds to pay a portion of its share of the associated liability. Reflecting this settlement, the receivable and the liability, recorded in the accompanying consolidated balance sheet as Other assets and Other liabilities and deferred credits, respectively, was $1.1 billion and $1.6 billion at December 31, 2011 and 2010, respectively.

	$	3,718

All short-term investments are classified as available-for-sale and stated at fair value. Unrealized gains and losses are reflected as a component of Accumulated other comprehensive income (loss).

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 of commodity collars and calls, 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. No changes in valuation techniques or inputs occurred during the year ended December 31, 2011.

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

Commitments, Contingencies And Guarantees

5. Commitments, Contingencies and Guarantees

On July 19, 2011, American entered into agreements (the Boeing Agreements) with The Boeing Company (Boeing) to acquire 100 additional Boeing 737 Next Generation aircraft (the firm NG Aircraft), which, subject to certain limitations, may consist of Boeing 737-700, 737-800, or 737-900 ER aircraft. The firm NG Aircraft include three Boeing 737-800 aircraft for which American exercised purchase rights on June 30, 2011. Twenty of the firm NG Aircraft are scheduled to be delivered in each of the years 2013-2017. Under the Boeing Agreements, American also expects to acquire 100 Boeing 737 Next Generation "re-engined" aircraft (the Boeing 737 MAX Aircraft), to be equipped with new, more fuel efficient engines. American's acquisition of Boeing 737 MAX Aircraft is subject to a number of conditions, including negotiation of definitive agreements with Boeing to acquire such aircraft. If acquired, 20 Boeing 737 MAX Aircraft would be scheduled to be delivered in each of the years 2018-2022. In addition, under the Boeing Agreements, American retained purchase rights for 40 Boeing 737 Next Generation aircraft, which, if exercised, would be delivered in the years 2015-2018, and acquired purchase rights for 60 additional Boeing 737 MAX Aircraft, which, if exercised, would be delivered in the years 2020-2025.

Boeing agreed to provide primary lease financing to American for the firm NG Aircraft. If American elects to use this lease financing on any firm NG Aircraft, then subject to certain terms and conditions, including the absence of defaults under certain other agreements, BCC Equipment Leasing Corporation (a subsidiary of Boeing) or a third party arranged by Boeing will enter into a lease for such aircraft with American for an initial term of ten years. Each lease will include customary terms and conditions, including covenants regarding maintenance, operation, registration, liens and insurance with respect to the aircraft, as well as defaults relating to payment and performance of lease obligations and certain cross-default arrangements. If American does not elect to lease any firm NG Aircraft using the lease financing provided by Boeing, American may purchase such aircraft using other financing provided by a third party and arranged directly by American.

Further, American entered into agreements (the Airbus Agreements) with Airbus S.A.S. (Airbus) on July 20, 2011. Under the Airbus Agreements, American committed to lease 130 Airbus current generation A320 family aircraft (the firm Current Generation Airbus Aircraft) which, subject to certain limitations, may consist of A319, A320 or A321 aircraft, and committed to purchase 130 Airbus A320 family "new engine option" aircraft (the firm NEO Airbus Aircraft), to be equipped with new, more fuel efficient engines. Between 20-35 of the firm Current Generation Airbus Aircraft are scheduled to be delivered in each of the years 2013-2017. Ten firm NEO Airbus Aircraft are scheduled to be delivered in 2017 and thereafter between 20-25 firm NEO Airbus Aircraft are scheduled to be delivered in each of the years 2018-2022. In addition, American acquired 70 options and 15 purchase rights for additional Airbus current generation A320 family aircraft, which, if exercised, would be delivered in years 2014-2017, and options for 280 additional Airbus A320 family "new engine option" aircraft, which, if exercised, would be delivered in the years 2017-2025. Under the Airbus Agreements, subject to American's rights to purchase firm Current Generation Airbus Aircraft in certain circumstances, and subject to certain terms and conditions, including the absence of defaults under certain other agreements, the firm Current Generation Airbus Aircraft will be financed under leases with initial terms of ten years with Airbus or one of its affiliates, or with a third party arranged by Airbus. The leases will include customary terms and conditions, including covenants regarding maintenance, operation, registration, liens and insurance with respect to the aircraft, as well as defaults relating to payment and performance of lease obligations and certain cross-default arrangements.

The Bankruptcy Court has not approved American's assumption of the Boeing and Airbus contracts, but has approved certain procedures to allow American to continue taking delivery of Boeing 737 and Boeing 777 aircraft for the remainder of 2012, subject to objection by the Creditors' Committee, and subject to certain limitations.

Reflecting the above transactions, American had total aircraft acquisition commitments as of December 31, 2011 as follows:

¹ As of December 31, 2011, American had elected to purchase nine of the firm NG aircraft using the sale-leaseback financing arranged directly by American with a third party leasing company.

These aircraft are therefore reflected as purchases in the above table. As of December 31, 2011, payments for the above purchase commitments and certain engines will approximate $1.2 billion in 2012, $1.5 billion in 2013, $494 million in 2014, $243 million in 2015, $276 million in 2016 and $7.1 billion for 2017 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 $746 million as of December 31, 2011.

As of December 31, 2011, total future lease payments for all leased aircraft, including aircraft not yet delivered, will approximate $905 million in 2012, $895 million in 2013, $1.0 billion in 2014, $1.2 billion in 2015, $1.4 billion in 2016 and $13.1 billion in 2017 and beyond.

In 2008, American entered into a purchase agreement with Boeing (subject to certain reconfirmation rights) to acquire 42 Boeing 787-9 aircraft, with the right to acquire an additional 58 Boeing 787-9 aircraft. The first such Boeing 787-9 aircraft is currently scheduled to be delivered (subject to such reconfirmation rights) in 2014. American has selected GE Aviation as the exclusive provider of engines for its expected order of Boeing 787-9 aircraft.

In 2010, American and Japan Airlines (JAL) entered into a Joint Business Agreement (JBA) to enhance their scope of cooperation on routes between North America and Asia through adjustments to their respective networks, flight schedules, and other business activities. The carriers also received antitrust immunity (ATI) approval on these routes from the DOT and the Ministry of Land, Infrastructure, Transport, and Tourism of Japan and began implementing the JBA on April 1, 2011. The JBA provides for expanded codesharing, enhanced frequent flyer program reciprocity, and cooperation in other areas. American and JAL entered into a Revenue Sharing Agreement, effective April 1, 2011, as envisaged by the JBA. Under this agreement, American and JAL share certain revenues of their operations. In addition, 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, 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 $75 million. As of December 31, 2011, based on an expected probability model, American had recorded a guarantee liability that is not material.

The Company has contracts related to facility construction or improvement projects, primarily at airport locations. The contractual obligations related to these projects totaled approximately $74 million as of December 31, 2011. The Company expects to make payments on these obligations of $44 million and $12 million in 2012 and 2013, respectively. In addition, the Company has an information technology support related contract that requires minimum annual payments of $90 million in 2012 and declining to $70 million in 2014 through 2019.

American has a capacity purchase agreement with Chautauqua Airlines, Inc. to provide Embraer -140 regional jet services to certain markets under the brand AmericanConnection^®. Under these arrangements, the Company pays the AmericanConnection^® carrier a fee per block hour to operate the aircraft. The block hour fees are designed to cover the AmericanConnection^® carrier's fully allocated costs plus a margin. Assumptions for certain costs such as fuel, landing fees, insurance, and aircraft ownership are trued up to actual values on a pass through basis. In consideration for these payments, the Company retains all passenger and other revenues resulting from the operation of the AmericanConnection^® regional jets. Minimum payments under the contracts are $60 million in 2012 and $5 million in 2013. In addition, if the Company terminates the Chautauqua contract without cause, Chautauqua has the right to put its 15 Embraer aircraft to the Company. If this were to happen, the Company would take possession of the aircraft and become liable for lease obligations totaling approximately $21 million per year with lease expirations in 2018 and 2019.

The Company is a party to many routine contracts in which it provides general indemnities in the normal course of business to third parties for various risks. The Company is not able to estimate the potential amount of any liability resulting from the indemnities. These indemnities are discussed in the following paragraphs.

In its aircraft financing agreements, the Company generally indemnifies the financing parties, trustees acting on their behalf and other relevant parties against liabilities (including certain taxes) resulting from the financing, manufacture, design, ownership, operation and maintenance of the aircraft regardless of whether these liabilities (or taxes) relate to the negligence of the indemnified parties.

The Company's loan agreements and other London Interbank Offered Rate (LIBOR)-based financing transactions (including certain leveraged aircraft leases) generally obligate the Company to reimburse the applicable lender for incremental costs due to a change in law that imposes (i) any reserve or special deposit requirement against assets of, deposits with or credit extended by such lender related to the loan, (ii) any tax, duty or other charge with respect to the loan (except standard income tax) or (iii) capital adequacy requirements. In addition, the Company's loan agreements, derivative contracts and other financing arrangements typically contain a withholding tax provision that requires the Company to pay additional amounts to the applicable lender or other financing party, generally if withholding taxes are imposed on such lender or other financing party as a result of a change in the applicable tax law.

These increased cost and withholding tax provisions continue for the entire term of the applicable transaction, and there is no limitation on the maximum additional amounts the Company could be obligated to pay under such provisions. Any failure to pay amounts due under such provisions generally would trigger an event of default and, in a secured financing transaction, would entitle the lender to foreclose on the collateral to realize the amount due.

In certain transactions, including certain aircraft financing leases and loans and derivative transactions, the lessors, lenders and/or other parties have rights to terminate the transaction based on changes in foreign tax law, illegality or certain other events or circumstances. In such a case, the Company may be required to make a lump sum payment to terminate the relevant transaction.

The Company has general indemnity clauses in many of its airport and other real estate leases where the Company as lessee indemnifies the lessor (and related parties) against liabilities related to the Company's use of the leased property. Generally, these indemnifications cover liabilities resulting from the negligence of the indemnified parties, but not liabilities resulting from the gross negligence or willful misconduct of the indemnified parties. In addition, the Company provides environmental indemnities in many of these leases for contamination related to the Company's use of the leased property.

Under certain contracts with third parties, the Company indemnifies the third party against legal liability arising out of an action by the third party, or certain other parties. The terms of these contracts vary and the potential exposure under these indemnities cannot be determined. The Company has liability insurance protecting the Company for some of the obligations it has undertaken under these indemnities.

AMR and American have event risk covenants in approximately $844 million of indebtedness and operating leases as of December 31, 2011. These covenants permit the holders of such obligations to receive a higher rate of return (between 100 and 600 basis points above the state rate) if a designated event, as defined, should occur and the credit ratings of such obligations are downgraded below certain levels within a certain period of time. No designated event, as defined, had occurred as of December 31, 2011.

The Company is involved in certain claims and litigation related to its operations. The Company is also subject to regulatory assessments in the ordinary course of business. AMR establishes reserves for litigation and regulatory matters when those matters present loss contingencies that are both probable and can be reasonably estimated. In the opinion of management, liabilities, if any, arising from these claims and litigation will not have a material adverse effect on the Company's consolidated financial position, results of operations, or cash flows, after consideration of available insurance.

As a result of the current Chapter 11 filings, attempts to prosecute, collect, secure or enforce remedies with respect to pre-petition 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.

Leases

Leases [Abstract]

Leases

6. Leases

AMR's subsidiaries lease various types of equipment and property, primarily aircraft and airport facilities. As allowed 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, leases of real property, aircraft, and aircraft engines, subject to the approval of the Bankruptcy Court and other conditions, including compliance with Section 1110 with respect to aircraft and aircraft-related assets. Consequently, the Company anticipates that its liabilities pertaining to leases will change significantly in the future.

The future minimum lease payments required under capital leases, together with the present value of such payments, and future minimum lease payments required under operating leases that have initial or remaining non-cancelable lease terms in excess of one year as of December 31, 2011, were (in millions):

As of December 31, 2011, included in Liabilities Subject to Compromise on the accompanying consolidated balance sheet is approximately $1.1 billion relating to rent expense being recorded in advance of future operating lease payments.

At December 31, 2011, the Company was operating 203 jet aircraft and 36 turboprop aircraft under operating leases and 60 jet aircraft under capital leases. The aircraft leases can generally be renewed at rates based on fair market value at the end of the lease term for one to five years. Some aircraft leases have purchase options at or near the end of the lease term at fair market value, but generally not to exceed a stated percentage of the defined lessor's cost of the aircraft or a predetermined fixed amount.

During 2011, the Company incurred approximately $31 million in non-recurring non-cash charges related to certain sale leaseback transactions. During 2010, the Company financed 36 deliveries of Boeing 737-800 aircraft through sale leaseback transactions resulting in gains which are being amortized over the respective remaining lease terms. During 2009 non-recurring charges related to losses on certain sale/leasebacks of vintage aircraft of $88 million were realized and included in Other operating income.

Special facility revenue bonds have been issued by certain municipalities primarily to improve airport facilities and purchase equipment. To the extent these transactions were committed to prior to May 21, 1998, they are accounted for as operating leases under U.S. GAAP. Approximately $1.5 billion of these bonds (with total future payments of approximately $3.2 billion as of December 31, 2011) are guaranteed by American, AMR, or both. Approximately $177 million of these special facility revenue bonds contain mandatory tender provisions that require American to make operating lease payments sufficient to repurchase the bonds at various times: $112 million in 2014 and $65 million in 2015. Although American has the right to remarket the bonds, there can be no assurance that these bonds will be successfully remarketed. Any payments to redeem or purchase bonds that are not remarketed would generally reduce existing rent leveling accruals or be considered prepaid facility rentals and would reduce future operating lease commitments. The special facility revenue bonds that contain mandatory tender provisions are listed in the table above at their ultimate maturity date rather than their mandatory tender provision date.

Rent expense, excluding landing fees, was $1.6 billion, $1.5 billion and $1.3 billion in 2011, 2010 and 2009, respectively.

American has determined that it holds a significant variable interest in, but is not the primary beneficiary of, certain trusts that are the lessors under 70 of its aircraft operating leases. These leases contain a fixed price purchase option, which allows American to purchase the aircraft at a predetermined price on a specified date. However, American does not guarantee the residual value of the aircraft. As of December 31, 2011, future lease payments required under these leases totaled $794 million.

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 December 31, 2011, 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

As of December 31, 2011, AMR had issued guarantees covering approximately $1.6 billion of American's tax-exempt bond debt (and interest thereon) and $4.4 billion of American's secured debt (and interest thereon), including debt related to aircraft transfers from AMR Eagle to American (see Note 17 to the consolidated financial statements). American had issued guarantees covering approximately $842 million of AMR's unsecured debt (and interest thereon). AMR also guarantees $105 million of American's leases of certain Super ATR aircraft, which are subleased to AMR Eagle.

On January 25, 2011, American closed on a $657 million offering of Class A and Class B Pass Through Trust Certificates, Series 2011-1 (the 2011-1 Certificates). The equipment notes held by each pass through trust were issued for each of (a) 15 Boeing 737-823 aircraft delivered new to American from 1999 to 2001, (b) six Boeing 757-223 aircraft delivered new to American in 1999 and 2001, (c) two Boeing 767-323ER aircraft delivered new to American in 1999 and (d) seven Boeing 777-223ER aircraft delivered new to American from 1999 to 2000. Interest of 5.25% and 7.00% per annum on the issued and outstanding Series A equipment notes and Series B equipment notes, respectively, will be payable semiannually on January 31 and July 31 of each year, commencing on July 31, 2011, and principal on such equipment notes is scheduled for payment on January 31 and July 31 of certain years, commencing on July 31, 2011. The payment obligations of American under the equipment notes are fully and unconditionally guaranteed by AMR. All proceeds from the sale of the Series 2011-1 Certificates have been received by American.

In March 2011, American issued $1 billion aggregate principal amount of senior secured notes due 2016 (the Senior Secured Notes) guaranteed by the Company. The Senior Secured Notes bear interest at a rate of 7.50% per annum, payable semi-annually on March 15 and September 15 of each year, beginning September 15, 2011. As is customary for financings of this nature, the indebtedness evidenced by the Senior Secured Notes may be accelerated upon the occurrence of events of default under the related indenture. The Senior Secured Notes are senior secured obligations of American and are unconditionally guaranteed on an unsecured basis by the Company. Subject to certain limitations and exceptions, the Senior Secured Notes are secured by certain route authorities, airport landing and takeoff slots, and rights to use or occupy space in airport terminals, in each case that American uses to operate non-stop services between certain airports in the United States and London's Heathrow Airport, and between certain airports in the United States and certain airports in Japan and China.

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

The indenture for the Senior Secured Notes includes covenants that, among other things, limit the ability of the Company and its subsidiaries to merge, consolidate, sell assets, incur additional indebtedness, issue preferred stock, make investments and pay dividends. In addition, if American fails to maintain a collateral ratio of 1.5 to 1.0, American must pay additional interest on the notes at the rate of 2% per annum until the collateral coverage ratio equals at least 1.5 to 1.0.

On October 4, 2011, American closed on a $726 million offering of Class A Pass Through Trust Certificates, Series 2011-2 (the 2011-2 Certificates). Subsequent to the closing, the equipment notes held by each pass through trust were issued for each of (a) 14 Boeing 737-823 aircraft delivered new to American from 1999 to 2001 and 2 Boeing 737-823 aircraft delivered new to American in 2009, (b) 14 Boeing 757-223 aircraft delivered new to American in 1999 and 2001 and (c) 13 Boeing 777-223ER aircraft delivered new to American in 2001. Interest of 8.625% per annum on the issued and outstanding 2011-2 Certificates will be payable semiannually on April 15 and October 15 of each year, commencing on April 15, 2012, and principal on such equipment notes is scheduled for payment on April 15 and October 15 of certain years, commencing on April 15, 2012. The payment obligations of American under the equipment notes are fully and unconditionally guaranteed by AMR. All proceeds from the sale of the Series 2011-2 Certificates have been received by American.

Further, in July 2011, American entered into a sale-leaseback arrangement with a leasing company to finance 35 Boeing 737-800 aircraft scheduled to be delivered in 2011 through 2014, subject to certain terms and conditions. During 2011, American financed 13 Boeing 737-800 aircraft under this and other arrangements, which are accounted for as operating leases.

In 2009, American entered into an arrangement under which Citibank paid to American $1.0 billion in order to pre-purchase AAdvantage Miles (the Advance Purchase Miles) under American's AAdvantage frequent flier loyalty program (the Advance Purchase). Approximately $890 million of the Advance Purchase proceeds is accounted for as a loan from Citibank with the remaining $110 million recorded as Deferred Revenue in Other liabilities and deferred credits.

To effect the Advance Purchase, American and Citibank entered into an Amended and Restated AAdvantage Participation (as so amended and restated, the Amended Participation Agreement). Under the Amended Participation Agreement, American agreed that it would apply in equal monthly installments, over a five year period beginning on January 1, 2012, the Advance Purchase Miles to Citibank cardholders' AAdvantage accounts.

Pursuant to the Advance Purchase, Citibank has been granted a first-priority lien on certain of American's AAdvantage program assets, and a second lien on the collateral that secures the Senior Secured Notes. Commencing on December 31, 2011, American has the right to repurchase, without premium or penalty, any or all of the Advance Purchase Miles that have not then been posted to Citibank cardholders' accounts. American is also obligated, in certain circumstances (including certain specified termination events under the Amended Participation Agreement, certain cross defaults and cross acceleration events, and if any Advance Purchase Miles remain at the end of the term) to repurchase for cash all of the Advance Purchase Miles that have not then been used by Citibank.

The Amended Participation Agreement includes provisions that grant Citibank the right to use Advance Purchase Miles on an accelerated basis under specified circumstances. American also has the right under certain circumstances to release, or substitute other comparable collateral for, the Heathrow and Narita route and slot related collateral.

At December 31, 2011, the Company had outstanding $460 million principal amount of its 6.25 percent senior convertible notes due 2014, which is classified as liabilities subject to compromise (see Note 1 to the consolidated financial statements). Each note is convertible by holders into shares of AMR common stock at an initial conversion rate of 101.0101 shares per $1,000 principal amount of notes (which represents an equivalent initial conversion price of approximately $9.90 per share), subject to adjustment upon the occurrence of certain events, at any time prior to the close of business on the business day immediately preceding the maturity date of the notes. The Company must pay the conversion price of the notes in common stock. If the holders of the notes do not convert prior to maturity, the Company will retire the debt in cash. These notes are guaranteed by American. In the case of the Senior Secured Notes, an additional alternative is to pay a higher rate of interest on such notes until such time, if any, as the loan to value ratio is below the specified threshold.

Certain of the Company's debt financing agreements contain loan to value ratio covenants and require the Company to periodically appraise the collateral. Pursuant to such agreements, if the loan to value ratio exceeds a specified threshold, we may be required to subject additional qualifying collateral (which in some cases may include cash collateral) or, in the alternative, to pay down such financing, in whole or in part, with premium (if any).

Specifically, the Company is required to meet certain collateral coverage tests on a periodic basis on three financing transactions: (1) 10.5% $450 million Senior Secured Notes due 2012, (2) Senior Secured Notes, and (3) 2005 Spare Engine EETC due in 2012, as described below:

At December 31, 2011, the Company was in compliance with the most recently completed collateral coverage tests for the Senior Secured Notes and the 2005 Spare Engine EETC, and was not in compliance with the most recently completed collateral coverage test for the 10.5% $450 million Senior Secured Notes due 2012. The Company has not remedied the covenant due to the ongoing Chapter 11 proceedings. The Company continues to monitor compliance with the Senior Secured Notes and the 2005 Spare Engine EETC covenants and, if needed, intends to take necessary steps as permitted by the Bankruptcy Court, to maintain compliance.

Cash payments for interest, net of capitalized interest, were $747 million, $735 million and $631 million for 2011, 2010 and 2009, respectively.

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

The Debtors cannot predict the impact, if any, that the Chapter 11 Cases might have on these obligations. For further information regarding the Chapter 11 Cases, see Note 1 to the consolidated financial statements.

Financial Instruments And Risk Management [Abstract]

Financial Instruments And Risk Management

8. Financial Instruments and Risk Management

Fuel Price Risk Management As part of the Company's risk management program, it uses a variety of financial instruments, primarily heating oil option and collar contracts, as cash flow hedges to mitigate commodity price risk. The Company does not hold or issue derivative financial instruments for trading purposes. As of December 31, 2011, the Company had fuel derivative contracts outstanding covering 16 million barrels of jet fuel that will be settled over the next 12 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.

In accordance with U.S. GAAP, the Company assesses, both at the inception of each hedge and on an ongoing basis, whether the derivatives that are used in its hedging transactions are highly effective in offsetting changes in cash flows of the hedged items. Derivatives that meet the requirements are granted special hedge accounting treatment, and the Company's hedges generally meet these requirements. Accordingly, the Company's fuel derivative contracts are accounted for as cash flow hedges, and the fair value of the Company's hedging contracts is recorded in Current Assets or Current Liabilities in the accompanying consolidated balance sheets until the underlying jet fuel is purchased. The Company determines the ineffective portion of its fuel hedge contracts by comparing the cumulative change in the total value of the fuel hedge contract, or group of fuel hedge contracts, to the cumulative change in a hypothetical jet fuel hedge. If the total cumulative change in value of the fuel hedge contract more than offsets the total cumulative change in a hypothetical jet fuel hedge, the difference is considered ineffective and is immediately recognized as a component of Aircraft fuel expense. Effective gains or losses on fuel hedging contracts are deferred in Accumulated other comprehensive income (loss) and are recognized in earnings as a component of Aircraft fuel expense when the underlying jet fuel being hedged is used.

Ineffectiveness is inherent in hedging jet fuel with derivative positions based in crude oil or other crude oil related commodities. In assessing effectiveness, the Company uses a regression model to determine the correlation of the change in prices of the commodities used to hedge jet fuel (e.g., NYMEX Heating oil) to the change in the price of jet fuel. The Company also monitors the actual dollar offset of the hedges' market values as compared to hypothetical jet fuel hedges. The fuel hedge contracts are generally deemed to be "highly effective" if the R-squared is greater than 80 percent and dollar offset correlation is within 80 percent to 125 percent. The Company discontinues hedge accounting prospectively if it determines that a derivative is no longer expected to be highly effective as a hedge or if it decides to discontinue the hedging relationship. Subsequently, any changes in the fair value of these derivatives are marked to market through earnings in the period of change.

For the years ended December 31, 2011, 2010 and 2009, the Company recognized net gains (losses) of approximately $335 million, ($142) million and $(651) million, respectively, as a component of Aircraft fuel expense on the accompanying consolidated statements of operations related to its fuel hedging agreements, including the ineffective portion of the hedges. The fair value of the Company's fuel hedging agreements at December 31, 2011 and 2010, representing the amount the Company would receive upon termination of the agreements (net of settled contract assets), totaled $80 million and $257 million, respectively. As of December 31, 2011, the Company estimates that during the next twelve months it will reclassify from Accumulated other comprehensive loss into earnings approximately $11 million in net gains (based on prices as of December 31, 2011) related to its fuel derivative hedges.

The impact of cash flow hedges on the Company's consolidated financial statements for the years ending December 31, 2011 and 2010, respectively, is depicted below (in millions):

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.

As of December 31, 2011, the Company had received collateral of $0.5 million which is included in short-term investments.

Fair Values of Financial Instruments The fair values of the Company's long-term debt were estimated using quoted market prices where available. For long-term debt not actively traded, fair values were estimated using discounted cash flow analyses, based on the Company's current incremental borrowing rates for similar types of borrowing arrangements.

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):

Income Taxes [Abstract]

Income Taxes

9. Income Taxes

The significant components of the income tax provision (benefit) were (in millions);

Current	$	(25	)	$	(5	)	$	(36	)
Deferred		25			(30	)		(248	)


Income tax benefit	$	0		$	(35	)	$	(284	)

The income tax expense (benefit) differed from amounts computed at the statutory federal income tax rate as follows (in millions):


	Year Ended December 31,
	2011			2010			2009
Statutory income tax provision expense/(benefit)	$	(691	)	$	(177	)	$	(613	)
State income tax expense/(benefit), net of federal tax effect		(37	)		(1	)		(41	)
Meal expense		8			7			7
Change in valuation allowance		705			121			597
Tax benefit resulting from OCI allocation		0			0			(248	)
Other, net		15			15			14

Income tax benefit	$	(0	)	$	(35	)	$	(284	)

The change in the valuation allowance reflects the recording by the Company in 2011, 2010 and 2009 of an income tax expense credit of approximately $0 million, $30 million and $36 million, respectively, resulting from the Company's elections under applicable sections of the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 and the Housing and Economic Recovery Act of 2008 (as extended by the American Recovery and Reinvestment Act of 2009), allowing corporations to accelerate utilization of certain research and alternative minimum tax (AMT) credit carryforwards in lieu of applicable bonus depreciation on certain qualifying capital investments.

In addition to the changes in the valuation allowance from operations described in the table above, the valuation allowance was also impacted by the changes in the components of Accumulated other comprehensive income (loss), described in Note 13 to the consolidated financial statements. The total increase in the valuation allowance was $1.2 billion, $121 million, and $135 million in 2011, 2010, and 2009, respectively.

The Company provides a valuation allowance for deferred tax assets when it is more likely than not that some portion, or all of its deferred tax assets, will not be realized. In assessing the realizability of the deferred tax assets, management considers whether it is more likely than not that some portion, or all of the deferred tax assets, will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income (including reversals of deferred tax liabilities) during the periods in which those temporary differences will become deductible.

The Company recorded a $248 million non-cash income tax benefit from continuing operations during the fourth quarter of 2009. Under current accounting rules, the Company is required to consider all items (including items recorded in other comprehensive income) in determining the amount of tax benefit that results from a loss from continuing operations and that should be allocated to continuing operations. As a result, the Company recorded a tax benefit on the loss from continuing operations for the year, which will be exactly offset by income tax expense on other comprehensive income. However, while the income tax benefit from continuing operations is reported on the income statement, the income tax expense on other comprehensive income is recorded directly to Accumulated other comprehensive income, which is a component of stockholders' equity. Because the income tax expense on other comprehensive income is equal to the income tax benefit from continuing operations, the Company's year-end net deferred tax position is not impacted by this tax allocation.

The components of AMR's deferred tax assets and liabilities were (in millions):


	December 31,
	2011			2010
Deferred tax assets:
Postretirement benefits other than pensions	$	1,074		$	1,056
Rent expense		325			333
Alternative minimum tax credit carryforwards		367			392
Operating loss carryforwards		2,389			2,271
Pensions		2,341			1,865
Frequent flyer obligation		681			630
Gains from lease transactions		28			55
Other		681			583

Total deferred tax assets		7,886			7,185
Valuation allowance		(4,148	)		(2,990	)

Net deferred tax assets		3,738			4,195

Deferred tax liabilities:
Accelerated depreciation and amortization		(3,543	)		(3,985	)
Other		(195	)		(185	)

Total deferred tax liabilities		(3,738	)		(4,170	)

Net deferred tax asset	$	0		$	25

At December 31, 2011, the Company had available for federal income tax purposes an AMT credit carryforward of approximately $367 million, which is available for an indefinite period, and federal net operating losses of approximately $7 billion for regular tax purposes, which will expire, if unused, beginning in 2022. These net operating losses include an unrealized benefit of approximately $666 million related to the implementation of share-based compensation accounting guidance that will be recorded in equity when realized. The Company had available for state income tax purposes net operating losses of $3.8 billion, which expire, if unused, in years 2012 through 2027. The amount that will expire in 2012 is $9 million.

The Company files its tax returns as prescribed by the tax laws of the jurisdictions in which it operates. The Company's 2004 through 2010 tax years are still subject to examination by the Internal Revenue Service. Various state and foreign jurisdiction tax years remain open to examination and the Company is under examination, in administrative appeals, or engaged in tax litigation in certain jurisdictions. The Company believes that the effect of any additional assessment(s) will be immaterial to its consolidated financial statements.

Cash payments (refunds) for income taxes were $1 million, $(32) million and $6 million for 2011, 2010 and 2009, respectively.

Under special tax rules (the Section 382 Limitation), cumulative stock ownership changes among material shareholders exceeding 50 percent during a 3-year period can potentially limit a company's future use of net operating losses and tax credits. Chapter 11 proceedings could impact the availability and utilization of net operating losses and tax credits. Based on available information, the Company believes it is not currently subject to the Section 382 Limitation.

The Company has an unrecognized tax benefit of approximately $6 million, which did not change during the twelve months ended December 31, 2011. Changes in the unrecognized tax benefit have no impact on the effective tax rate due to the existence of the valuation allowance. Accrued interest on tax positions is recorded as a component of interest expense but was not significant at December 31, 2011.

The reconciliation of the beginning and ending amounts of unrecognized tax benefit are (in millions):


	2011		2010

Unrecognized Tax Benefit at January 1	$	6	$	6
No Activity		0		0

Unrecognized Tax Benefit at December 31	$	6	$	6

The Company estimates that the unrecognized tax benefit will not significantly change within the next twelve months.

Share Based Compensation [Abstract]

Share Based Compensation

10. Share Based Compensation

Prior to the Petition Date, the Company adopted certain plans which provide for the issuance of common stock in connection with the exercise of stock options and for other stock-based awards. AMR has granted stock compensation under three plans: the 1998 Long Term Incentive Plan (the 1998 Plan), the 2003 Employee Stock Incentive Plan (the 2003 Plan) and the 2009 Long Term Incentive Plan (the 2009 Plan). Collectively, the 1998 Plan and the 2009 Plan are referred to as the LTIP Plans.

The Company believes that all of its stock options will be cancelled as part of its emergence from Chapter 11. The following includes additional information about these plans as of December 31, 2011. It is expected that no future awards will be made under these plans.

Under the LTIP Plans, officers and key people of AMR and its subsidiaries were granted certain types of stock or performance based awards. At December 31, 2011, the Company had stock option awards, stock appreciation right (SAR) awards, performance share awards, deferred share awards and other awards outstanding under these plans. The total number of common shares authorized for distribution under the 1998 Plan and the 2009 Plan is 23,700,000 and 4,000,000 shares, respectively. The 1998 Plan expired by its terms in 2008.

The Company established the 2003 Plan to provide equity awards to employees. Under the 2003 Plan, employees may be granted stock options, restricted stock and deferred stock. At December 31, 2011, the Company had stock options and deferred awards outstanding under this plan. The total number of shares authorized for distribution under the 2003 Plan is 42,680,000 shares.

In 2011, 2010 and 2009 the total charge for share-based compensation expense included in Wages, salaries and benefits expense was $40 million, $53 million and $61 million, respectively. In 2011, 2010 and 2009, the amount of cash used to settle equity instruments granted under share-based compensation plans was $2 million, $2 million and $1 million, respectively.

Stock Options/SARs During 2006, the AMR Board of Directors approved an amendment covering all of the outstanding stock options previously granted under the 1998 Plan. The amendment added to each of the outstanding options an additional SAR in tandem with each of the then outstanding stock options. The addition of the SAR did not impact the fair value of the stock options, but simply allowed the Company to settle the exercise of the option by issuing the net number of shares equal to the in-the-money value of the option. This amendment is estimated to make available enough shares to permit the Company to settle all outstanding performance and deferred share awards under the 1998 Plan in stock rather than cash.

Options/SARs granted under the LTIP Plans and the 2003 Plan are awarded with an exercise price equal to the fair market value of the stock on date of grant, become exercisable in equal annual installments over periods ranging from three to five years and expire no later than ten years from the date of grant. Expense for the options is recognized on a straight-line basis. The fair value of each award is estimated on the date of grant using the modified Black-Scholes option valuation model and the assumptions noted in the following table. Expected volatilities are based on implied volatilities from traded options on the Company's stock, historical volatility of the Company's stock, and other factors. The Company uses historical employee exercise data to estimate the expected term of awards granted used in the valuation model. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant. The dividend yield is assumed to be zero based on the Company's history and expectation of not paying dividends.


	2011		2010		2009
Expected volatility		73.5% to 75.4%		74.4% to 75.9%		73.6% to 76.7%
Expected term (in years)		4.0		4.0		4.0
Risk-free rate		0.90% to 2.11%		1.18% to 2.58%		2.33% to 2.46%
Annual forfeiture rate		10.0%		10.0%		10.0%

A summary of stock option/SARs activity under the LTIP Plans and the 2003 Plan as of December 31, 2011, and changes during the year then ended is presented below:


	LTIP Plans					The 2003 Plan
	Options/SARs			Weighted Average Exercise Price		Options			Weighted Average Exercise Price
Outstanding at January 1		15,384,288		$	13.99		13,208,383		$	5.66

Weighted Average Remaining Contractual Term of Options Outstanding (in years)		6.6					1.4


Aggregate Intrinsic Value of Options Outstanding	$	0				$	0

The aggregate intrinsic value of all vested options/SARs is $0 and those options have an average remaining contractual life of 2.5 years. The weighted-average grant date fair value of options/SARs granted during 2011, 2010 and 2009 was $3.59, $3.97 and $2.54, respectively. The total intrinsic value of options/SARs exercised during 2011, 2010 and 2009 was less than $1 million, $1 million and less than $1 million, respectively.

A summary of the status of the Company's non-vested options/SARs under all plans as of December 31, 2011, and changes during the year ended December 31, 2011, is presented below:


				Weighted
	Options/SARs			Average Grant Date Fair Value
Outstanding at January 1		8,096,002		$	3.83
Granted		2,556,305			3.59
Vested		(2,195,172	)		4.46
Forfeited		(989,116	)		3.59


Outstanding at December 31		7,468,019		$	3.59

As of December 31, 2011, there was $11 million of total unrecognized compensation cost related to non-vested stock options/SARs granted under the LTIP Plans and the 2003 Plan that is expected to be recognized over a weighted-average period of 3.2 years. The total fair value of stock options/SARs vested during the years ended December 31, 2011, 2010 and 2009, was $7 million, $11 million and $10 million, respectively.

Cash received by the Company from exercise of stock options for the years ended December 31, 2011, 2010 and 2009, was $1 million for each of those years. No tax benefit was realized as a result of stock options/SARs exercised in 2011 due to the tax valuation allowance discussed in Note 9.

Performance Share Awards Performance share awards are granted under the LTIP Plans, generally vest pursuant to a three year measurement period and are settled on the vesting date. The number of awards ultimately issued under performance share awards is contingent on AMR's relative stock price performance compared to certain of its competitors over a three year period and can range from zero to 175 percent of the awards granted. The fair value of performance awards is calculated by multiplying the stock price on the date of grant by the expected payout percentage and the number of shares granted.

Activity during 2011 for performance awards accounted for as equity awards was:


	Awards			Weighted Average Remaining Contractual Term		Aggregate Intrinsic Value
Outstanding at January 1		9,290,446
Granted		795,305
Settled		(1,392,447	)
Forfeited or Expired		(2,351,609	)


Outstanding at December 31		6,341,695			0.8	$	2,219,593

The aggregate intrinsic value represents the Company's current estimate of the number of shares (6,341,695 shares at December 31, 2011) that will ultimately be distributed for outstanding awards computed using the market value of the Company's common stock at December 31, 2011. The weighted-average grant date fair value per share of performance share awards granted during 2011, 2010, and 2009 was $6.58, $7.01 and $4.53, respectively. The total fair value of equity awards settled during the year ended December 31, 2011 was $7 million. As of December 31, 2011, there was $9 million of total unrecognized compensation cost related to performance share awards that is expected to be recognized over a period of 1.2 years

Deferred Share Awards The distribution of deferred share awards granted under the LTIP Plans is based solely on a requisite service period (generally 36 months). Career equity awards granted to certain employees of the Company vest upon the retirement of those individuals. The fair value of each deferred award is based on AMR's stock price on the measurement date.

Activity during 2011 for deferred awards accounted for as equity awards was:


	Shares			Weighted Average Remaining Contractual Term		Aggregate Intrinsic Value
Outstanding at January 1		8,724,559
Granted		1,068,391
Settled		(1,416,519	)
Forfeited or Expired		(1,105,410	)


Outstanding at December 31		7,271,021			1.6	$	2,544,858

The weighted-average grant date fair value per share of deferred awards granted during 2011, 2010 and 2009 was $6.29, $7.05 and $4.57, respectively. The total fair value of awards settled during the years ended December 31, 2011, 2010 and 2009 was $1 million, $3 million and $3 million, respectively. As of December 31, 2011, there was $15 million of total unrecognized compensation cost related to deferred awards that is expected to be recognized over a weighted average period of 2.1 years.

Other Awards As of December 31, 2011, certain performance share agreements and deferred share award agreements were accounted for as a liability, or as equity, as appropriate, in the consolidated balance sheet as the plans only permit settlement in cash or the awards required that the employee meet certain performance conditions which were not subject to market measurement. As a result, awards under these agreements are marked to current market value. As of December 31, 2011, the aggregate intrinsic value of these awards was $1 million and the weighted average remaining contractual term of these awards was 2.2 years. The total fair value of awards settled during the years ended December 31, 2011, 2010 and 2009 was $2 million, $2 million, and $1 million respectively. As of December 31, 2011, there was $1 million of total unrecognized compensation cost related to other awards that is expected to be recognized over a weighted average period of 2.3 years.

Due to its Chapter 11 filings, the Company does not plan to continue to distribute shares to recipients under any outstanding equity-based awards.

Retirement Benefits [Abstract]

Retirement Benefits

11. Retirement Benefits

All employees of the Company may participate in pension plans if they meet the plans' eligibility requirements. The defined benefit plans provide benefits for participating employees based on years of service and average compensation for a specified period of time before retirement. The Company uses a December 31 measurement date for all of its defined benefit plans. American's pilots also participate in a defined contribution plan for which Company contributions are determined as a percentage (11 percent) of participant compensation. Certain non-contract employees (including all new non-contract employees) participate in a defined contribution plan in which the Company will match the employees' before-tax contribution on a dollar-for-dollar basis, up to 5.5 percent of their pensionable pay. The effect of the Chapter 11 Cases on the Company's obligations for retirement benefits cannot be predicted at this time.

In addition to pension benefits, retiree medical and other postretirement benefits, including certain health care and life insurance benefits (which provide secondary coverage to Medicare), are provided to retired employees. The amount of health care benefits is limited to lifetime maximums as outlined in the plan. Certain employees of American and employees of certain other subsidiaries may become eligible for these benefits if they satisfy eligibility requirements during their working lives.

Certain employee groups make contributions toward funding a portion of their retiree health care benefits during their working lives. The Company funds benefits as incurred and makes contributions to match employee prefunding.

The following table provides a reconciliation of the changes in the pension and retiree medical and other benefit obligations and fair value of assets for the years ended December 31, 2011 and 2010, and a statement of funded status as of December 31, 2011 and 2010 (in millions):

Expected return on plan assets		8.50			8.50			8.50			8.50

As of December 31, 2011, the Company's estimate of the long-term rate of return on plan assets was 8.25 percent based on the target asset allocation. Expected returns on longer duration bonds are based on yields to maturity of the bonds held at year-end. Expected returns on other assets are based on a combination of long-term historical returns, actual returns on plan assets achieved over the last ten years, current and expected market conditions, and expected value to be generated through active management, currency overlay and securities lending programs. The Company's annualized ten-year rate of return on plan assets as of December 31, 2011, was approximately 8.58 percent.

The objectives of the Company's investment policies are to: maintain sufficient income and liquidity to pay retirement benefits; produce a long-term rate of return that meets or exceeds the assumed rate of return for plan assets; limit the volatility of asset performance and funded status; and diversify assets among asset classes and investment managers.

Based on these investment objectives, a long-term strategic asset allocation has been established. This strategic allocation seeks to balance the potential benefit of improving funded position with the potential risk that the funded position would decline. The current strategic target asset allocation is as follows:


Asset Class/Sub-Class	Allowed Range


Equity		60% - 70%
Public:
U.S. Value		18% - 33%
International Value		14% - 24%
Emerging Markets		5% - 11%
Alternative Investments		0% - 18%
Fixed Income		30% - 40%
U.S. Long Duration		30% - 40%

Other		0% - 5%
Cash Equivalents		0% - 5%

Each asset class is actively managed and, historically, the plans' assets have produced returns, net of management fees, in excess of the expected rate of return over the last ten years. Stocks and emerging market bonds are used to provide diversification and are expected to generate higher returns over the long-term than longer duration U.S. bonds. Public stocks are managed using a value investment approach in order to participate in the returns generated by stocks in the long-term, while reducing year-over-year volatility. Longer duration U.S. bonds are used to partially hedge the assets from declines in interest rates. Alternative (private) investments are used to provide expected returns in excess of the public markets over the long-term. Additionally, the Company engages currency overlay managers in an attempt to increase returns by protecting non-U.S. dollar denominated assets from a rise in the relative value of the U.S. dollar. The Company also participates in securities lending programs to generate additional income by loaning plan assets to borrowers on a fully collateralized basis. These programs are subject to market risk.

Investments in securities traded on recognized securities exchanges are valued at the last reported sales price on the last business day of the year. Securities traded in the over-the-counter market are valued at the last bid price. The money market fund is valued at fair value which represents the net asset value of the shares of such fund as of the close of business at the end of the period. Investments in limited partnerships are carried at estimated net asset value as determined by and reported by the general partners of the partnerships and represent the proportionate share of the estimated fair value of the underlying assets of the limited partnerships. Common/collective trusts are valued at net asset value based on the fair values of the underlying investments of the trusts as determined by the sponsor of the trusts. The 103-12 investment trust is valued at net asset value which is determined by the issuer at the end of each month and is based on the aggregate fair value of trust assets less liabilities, divided by the number of units outstanding. No changes in valuation techniques or inputs occurred during the period.

The fair values of the Company's pension plan assets at December 31, 2011 and 2010, by asset category are as follows:

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 and the Pension Protection Act of 2006.

As a result of the Chapter 11 Cases, AMR contributed $6.5 million to its defined benefit pension plans on January 13, 2012 to cover the post-petition period of November 29, 2011 to December 31, 2011. As a result of only contributing the post-petition portion of the required contribution, the Pension Benefit Guaranty Corporation filed a lien against certain assets of the Company. The Company's 2012 contribution to its defined benefit pension plans is subject to the Chapter 11 proceedings.

The following benefit payments, which reflect expected future service as appropriate, are expected to be paid:

Intangible Assets

Intangible Assets [Abstract]

Intangible Assets

12. Intangible Assets

The Company has recorded international slot and route authorities of $708 million as of December 31, 2011 and 2010. The Company considers these assets indefinite life assets and as a result, they are not amortized but instead are tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. Such triggering events may include significant changes to the Company's network or capacity, or the implementation of open skies agreements in countries where the Company operates flights.

As there is minimal market activity for the valuation of routes and international slots and landing rights, the Company measures fair value with inputs using the income approach. The income approach uses valuation techniques, such as future cash flows, to convert future amounts to a single present discounted amount. The inputs utilized for these valuations are unobservable and reflect the Company's assumptions about market participants and what they would use to value the routes and accordingly are considered Level 3 in the fair value hierarchy. The Company's unobservable inputs are developed based on the best information available as of December 31, 2011.

The following tables provide information relating to the Company's amortized intangible assets as of December 31 (in millions):


	2011
			Accumulated
	Cost		Amortization		Net Book Value
Amortized intangible assets:
Airport operating rights	$	515	$	364	$	151
Gate lease rights		160		125		35

Total	$	675	$	489	$	186


	2010
	Cost		Accumulated Amortization		Net Book Value
Amortized intangible assets:
Airport operating rights	$	515	$	344	$	171
Gate lease rights		182		129		53

Total	$	697	$	473	$	224

Airport operating and gate lease rights are being amortized on a straight-line basis over 25 years to a zero residual value. The Company recorded amortization expense related to these intangible assets of approximately $27 million, $28 million, and $28 million for the years ended December 31, 2011, 2010 and 2009, respectively. The Company expects to record annual amortization expense averaging approximately $22 million in each of the next five years related to these intangible assets.

Segment Reporting [Abstract]

Segment Reporting

15. Segment Reporting

The Company's operations of American and AMR Eagle are treated as an integrated route network and the route scheduling system maximizes the operating results of the Company. The Company's chief operating decision maker makes resource allocation decisions to maximize the Company's consolidated financial results. Based on the way the Company treats the network and the manner in which resource allocation decisions are made, the Company has only one operating segment for financial reporting purposes consisting of the operations of American and AMR Eagle.

American, AMR Eagle and the AmericanConnection^® airline serve more than 250 cities in approximately 50 countries with, on average, 3,400 daily flights. The combined network fleet numbers approximately 900 aircraft. American is also one of the largest scheduled air freight carriers in the world, providing a wide range of freight and mail services to shippers throughout its system onboard American's passenger fleet. AMR Eagle owns two regional airlines, which do business as "American Eagle" - American Eagle Airlines, Inc. and Executive Airlines, Inc. The American Eagle^® carriers provide service from throughout the U.S., Canada, Mexico and the Caribbean.

Revenues from other segments are below the quantitative threshold for determining reportable segments and consist primarily of revenues from Americas Ground Services, Inc. The difference between the financial information of the Company's one reportable segment and the financial information included in the accompanying consolidated statements of operations and balance sheets as a result of these entities is not material.

The Company's operating revenues by geographic region (as defined by DOT) are summarized below (in millions):

		0000000000		0000000000		0000000000
	Year Ended December 31,
	2011		2010		2009

DOT Domestic	$	13,804	$	13,081	$	11,974
DOT Latin America		5,460		4,619		4,114
DOT Atlantic		3,499		3,365		2,973
DOT Pacific		1,216		1,105		856


Total consolidated revenues	$	23,979	$	22,170	$	19,917

The Company attributes operating revenues by geographic region based upon the origin and destination of each flight segment. The Company's tangible assets consist primarily of flight equipment, which are mobile across geographic markets and, therefore, have not been allocated.

- Definition

The entire disclosure for reporting segments including data and tables. Reportable segments include those that meet any of the following quantitative thresholds a) it's reported revenue, including sales to external customers and intersegment sales or transfers is 10 percent or more of the combined revenue, internal and external, of all operating segments b) the absolute amount of its reported profit or loss is 10 percent or more of the greater, in absolute amount of 1) the combined reported profit of all operating segments that did not report a loss or 2) the combined reported loss of all operating segments that did report a loss c) its assets are 10 percent or more of the combined assets of all operating segments.

AMR Eagle Divestiture	12 Months Ended
AMR Eagle Divestiture	Dec. 31, 2011
AMR Eagle Divestiture [Abstract]
AMR Eagle Divestiture	17. AMR Eagle Divestiture On August 11, 2011, AMR Eagle filed a Form 10 registration statement (subsequently amended on September 26, 2011 and October 6, 2011) with the Securities and Exchange Commission in connection with a potential spin-off of AMR Eagle. As contemplated by the Form 10, on August 31, 2011, American entered into a Master Purchase Agreement (the Purchase Agreement) with Eagle and Executive under which Eagle sold to American 47 CRJ-700 Jet Aircraft and 216 Embraer 135, 140 and 145 Jet Aircraft, including the engines installed on each such aircraft and other related assets (each, a Jet Aircraft). In addition, American purchased from Eagle and Executive certain specified fixed assets, generally consisting of equipment and leasehold improvements owned by Eagle or Executive and used in connection with the regional flight operations conducted by Eagle and Executive on American's behalf and the ground handling operations of Eagle and Executive (collectively, the Other Assets). Each Jet Aircraft was purchased by American on the date of delivery of such aircraft to American, and the Other Assets was purchased by American ten days after delivery of the last Jet Aircraft to American, or November 27, 2011. Delivery of the Jet Aircraft began on August 31, 2011, and the last Jet Aircraft was delivered on November 17, 2011. Following the delivery of each Jet Aircraft, American has leased the Jet Aircraft to Eagle, and Eagle continues to provide certain regional flight operations to American. American has taken each Jet Aircraft subject to, and Eagle has been released from, all outstanding indebtedness relating to such Jet Aircraft. The indebtedness related to the Jet Aircraft consists of individual notes for each Jet Aircraft. The notes are secured by the related Jet Aircraft and certain other assets, have either fixed or floating interest rates and mature over various periods through 2023. As of December 31, 2011, the fixed rate notes had effective interest rates ranging from 4.25% to 7.50% and the floating rate notes had effective interest rates ranging from 2.247% to 3.261%. The notes include customary terms and conditions, including customary events of default and certain cross-default provisions. As of the end of 2011, the net book value of such transferred Jet Aircraft was $2.3 billion, and the aggregate outstanding indebtedness (net of discount) associated with such transferred Jet Aircraft was $2.1 billion, including liabilities classified as not subject to compromise and liabilities classified as subject to compromise. As a result of the Chapter 11 Cases, AMR's planned divestiture of AMR Eagle has been placed on hold, pending the outcome of the restructuring.

Subsequent Events [Abstract]
Subsequent Events	18. Subsequent Events On February 1, 2012, the Company announced the principal terms of a new business plan. The chief components of this business plan include targets of an annual $2 billion in cost savings and $1 billion in revenue enhancement. The business plan contemplates, among other things, reducing headcount by approximately 13,000, terminating American's defined benefit pension plans, and discontinuing subsidized retiree medical coverage for current employees. The Company may incur significant accounting charges as a result of the business plan, including severance costs and pension related curtailment or settlement charges. The business plan will require collaboration with the Creditors Committee, various economic stakeholders and union representatives, and in some instances, approval of the Bankruptcy Court. The Company cannot predict whether, or to what extent, the business plan will be implemented. As such, at this time, the Company is not able to reasonably estimate the amount and timing of such charges or the portion of these charges that will result in future cash expenditures.

- Definition

1) For defined benefit pension plans, the benefit obligation is the projected benefit obligation, which is the actuarial present value as of a date of all benefits attributed by the pension benefit formula to employee service rendered prior to that date. 2) For other postretirement defined benefit plans, the benefit obligation is the accumulated postretirement benefit obligation, which is the actuarial present value of benefits attributed to employee service rendered to a particular date.

- Definition

Assets, usually stocks, bonds, and other investments, that have been segregated and restricted (usually in a trust) to provide benefits, at their fair value as of the measurement date. Plan assets include amounts contributed by the employer (and by employees for a contributory plan) and amounts earned from investing the contributions, less benefits paid. If a plan has liabilities other than for benefits, those non-benefit obligations may be considered as reductions of plan assets.
