American Airlines Group Inc.

Warrants to Purchase 13,703,876 Shares of Common Stock

13,703,876 Shares of Common Stock

This prospectus supplement covers the resale of warrants (the “Warrants”) to purchase up to 13,703,876 shares of our common stock, par value $0.01 per share, and the shares of such common stock (the “Warrant Shares”) issuable upon the exercise of the Warrants, in each case, by the selling securityholder named herein.

On April 20, 2020 (the “PSP Closing Date”), American Airlines, Inc. (“American”), Envoy Air Inc., Piedmont Airlines, Inc. and PSA Airlines, Inc., each a wholly-owned subsidiary of our company, entered into a Payroll Support Program Agreement (the “PSP Agreement”) with the United States Department of the Treasury (“Treasury”), with respect to the payroll support program (the “Payroll Support Program”) under the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”). In connection with our entry into the PSP Agreement, on the PSP Closing Date, we entered into a Warrant Agreement (the “Warrant Agreement”) with Treasury.

Pursuant to the PSP Agreement, Treasury provided us with financial assistance in the aggregate amount of approximately $5,815 million. As partial compensation to the U.S. Government for the provision of financial assistance under the Payroll Support Program, we issued the Warrants to Treasury pursuant to the Warrant Agreement. The initial exercise price of each Warrant Share is $12.51 (which was the closing price of our common stock on The Nasdaq Global Select Market (“Nasdaq”) on April 9, 2020). The exercise price and the number of Warrant Shares to be issued are subject to adjustment as a result of certain anti-dilution provisions provided for in the Warrants.

We agreed to register the resale of the Warrants and Warrant Shares pursuant to the Warrant Agreement.

The selling securityholder may sell the Warrants and Warrant Shares described in this prospectus supplement in a number of different ways and at varying prices. We provide more information about how the selling securityholder may sell its Warrants and Warrant Shares in the section of this prospectus supplement entitled “Plan of Distribution.” We will not pay any underwriting discounts or commissions in connection with sales of the Warrants or Warrant Shares under this prospectus supplement. We are paying the cost of registering the Warrants and Warrant Shares covered by this prospectus supplement, as well as various related expenses. The selling securityholder is responsible for all selling commissions, transfer taxes and other costs related to the sale of the Warrants and Warrant Shares covered by this prospectus supplement.

We may amend or supplement this prospectus supplement from time to time by filing amendments or supplements as required. You should read the entire prospectus supplement and any amendments or supplements carefully before you make your investment decision.

Our common stock is listed on Nasdaq under the symbol “AAL.” On August 27, 2020, the last reported sale price of our common stock on Nasdaq was $13.28 per share.

Investing in our securities involves risks. See “Risk Factors” beginning on page S-4.

These risks and uncertainties include, but are not limited to, those set forth: (i) under the heading “Risk Factors” set forth elsewhere in this prospectus supplement, (ii) in our most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, as applicable, (especially in Management’s Discussion and Analysis of Financial Condition and Results of Operations, Quantitative and Qualitative Disclosures About Market Risk and Risk Factors) and (iii) in the Company’s other filings with the SEC.

RISK FACTORS

An investment in the Warrants and the Warrant Shares involves certain risks. You should carefully consider the risks described below in addition to those discussed from time to time in the “Risk Factors” section of our most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, as applicable, as well as the other information included or incorporated by reference in this prospectus supplement, before making an investment decision.

Our business, financial condition or results of operations could be materially adversely affected by any of these risks. The market or trading price of our common stock could decline due to any of these risks, and you may lose all or part of your investment. In addition, please read “Special note about forward-looking statements” in this prospectus supplement, where we describe additional uncertainties associated with our business and the forward-looking statements included or incorporated by reference in this prospectus supplement. Please note that additional risks not presently known to us or that we currently deem immaterial may also impair our business, financial condition or results of operations. The risk factors set forth in this prospectus supplement are in addition to, and not meant to be in lieu of, those that are in our reports referred to above and incorporated herein by reference from time to time.

Sales of shares of our common stock by the selling securityholder may cause our stock price to decline.

As of July 31, 2020, we had 508,561,718 shares of common stock outstanding. Sales of substantial amounts of our shares of common stock in the public market by the selling securityholder, or the perception that those sales may occur, could cause the market price of shares of our common stock to decline and impair our ability to raise capital through the sale of additional shares of our common stock.

USE OF PROCEEDS

We will not receive any of the proceeds from the sale or other disposition of the Warrants or the Warrant Shares held by the selling securityholder pursuant to this prospectus supplement.

We will bear the out-of-pocket costs, expenses and fees incurred in connection with the registration of the Warrants or Warrant Shares to be sold by the selling securityholder, including all registration, filing and listing fees, printing expenses, fees and disbursements of our counsel, blue sky fees and expenses, the reasonable fees and disbursements of the selling securityholder’s counsel, and expenses of our independent accountants (collectively, the “Registration Expenses”). The selling securityholder will bear all discounts, selling commissions and stock transfer taxes applicable to the sale of the Warrants or Warrant Shares and fees and disbursements to the selling securityholder’s counsel not included in the Registration Expenses.

DESCRIPTION OF WARRANTS

On the PSP Closing Date, American, Envoy Air Inc., Piedmont Airlines, Inc. and PSA Airlines, Inc., each a wholly-owned subsidiary of our company, entered into the PSP Agreement with Treasury with respect to the Payroll Support Program under the CARES Act. In connection with our entry into the PSP Agreement, on the PSP Closing Date, we entered into the Warrant Agreement with Treasury.

Pursuant to the PSP Agreement, Treasury provided us with financial assistance in the aggregate amount of approximately $5,815 million. As partial compensation to the U.S. Government for the provision of financial assistance under the Payroll Support Program, we issued the Warrants to Treasury to purchase up to 13,703,876 shares of our common stock pursuant to the Warrant Agreement. The initial exercise price of each Warrant Share is $12.51 (which was the closing price of our common stock on Nasdaq on April 9, 2020). The exercise price and the number of Warrant Shares to be issued are subject to adjustment as a result of certain anti-dilution provisions provided for in the Warrants.

The following is a summary of the general terms of the Warrants. This description is not complete and is subject to, and qualified in its entirety by reference to, the Warrants and the Warrant Agreement, copies of which are filed as exhibits to our Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2020.

Exercisability

The Warrants may be exercised, in whole or in part, at any time on or after their date of issuance, by delivering to us the exercised Warrant and a written notice of election to exercise such Warrant. Each Warrant is exercisable until the fifth anniversary of the issuance date of the applicable Warrant.

Exercise Price

The Warrants have an initial exercise price of $12.51 per share (which was the closing price of our common stock on Nasdaq on April 9, 2020). The exercise price is subject to certain anti-dilution provisions provided for in the Warrants.

Exercise

Upon our receiving a notice of exercise from a holder of the Warrants, we may choose whether to settle through net cash settlement or net share settlement. The holder of the Warrants does not elect whether the Warrants are settled in cash or in shares.

If we choose to settle through net cash settlement, the holder of the Warrants will not receive any shares of our common stock from the exercise; the holder will be entitled to receive cash equal to the product obtained by multiplying (A-B) by (C), where:

(A) = the average market price of a share of our common stock for the 15 consecutive trading day period ending on and including the trading day immediately preceding the date of exercise;

(B) = the exercise price per share of our common stock;

(C) = the number of shares of our common stock as to which the Warrant has been exercised.

If we choose to settle through net share settlement, the holder of the Warrants will be entitled to a number of shares of our common stock equal to the product obtained by multiplying (A-B)/A by C, where the letters have the same meanings indicated above.

S-5

Adjustments to Number of Shares and Exercise Price

The Warrants provide for proportional adjustment of the number and kind of securities issuable upon exercise of the Warrants and the per share exercise price upon the occurrence of certain events, such as stock splits, combinations, reverse stock splits and similar events. The Warrants also contain certain anti-dilution protections providing for the adjustment of the number and kind of securities issuable upon exercise of the Warrants and the per share exercise price due to certain repurchases of common stock, certain issuances of securities or certain distributions to securityholders.

Transferability

Subject to applicable laws, the Warrants are freely transferable. Pursuant to the Warrant Agreement, holders of the Warrants must provide us at least 30 days’ notice prior to selling the Warrants pursuant to the registration statement of which this prospectus supplement is a part.

Rights as a Stockholder

Except as otherwise provided in the Warrants or Warrant Agreement or by virtue of a holder’s ownership of shares of our common stock, the holders of Warrants do not have rights or privileges of holders of our common stock, including any voting rights, unless and until they exercise their Warrants.

Business Combinations

In the case of any merger, consolidation, share exchange or similar transaction that requires approval of our shareholders (“Business Combination”) or reclassification of our common stock, a holder’s right to receive our common stock upon exercise of the Warrants shall be converted into the right to exercise the Warrants to acquire the number of shares of stock, other securities or property that our common stock would have been entitled to receive upon consummation of the Business Combination or reclassification.

No Fractional Shares

No fractional shares of our common stock will be issued upon exercise of the Warrants. If, upon exercise of the Warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon exercise, round down to the nearest whole number of shares of common stock to be issued to the holder of the Warrants and pay such holder cash in lieu of such fractional interest in our common stock.

No Listing

We do not plan on applying to list the Warrants on Nasdaq, any other national securities exchange or any other nationally recognized trading system.

Registration

Pursuant to the Warrant Agreement, we have agreed to use reasonable best efforts to keep the registration statement of which this prospectus supplement is a part (or a replacement) continuously effective and in compliance with the Securities Act until, subject to certain exceptions, the Warrants and Warrant Shares: (i) have been sold pursuant to an effective registration statement; (ii) are able to be sold pursuant to Rule 144 of the Securities Act without limitation on volume or manner of sale; (iii) cease to be outstanding; or (iv) have been sold in a private transaction in which the transferor’s rights under the Warrant Agreement are not assigned to the transferee of the securities.

Indemnification

Under the Warrants and Warrant Agreement, subject to certain exceptions, we agreed to indemnify the holders of the Warrants and certain related persons and entities against any losses, claims, damages, actions,

S-6

liabilities, costs and expenses, arising out of or based on any untrue statement or alleged untrue statement of material fact contained in any registration statement or any document contained therein prepared or authorized by us in writing for use by the holders, including the registration statement of which this prospectus supplement is a part (or a replacement), or any omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

S-7

SELLING SECURITYHOLDER

We are registering the resale of warrants (the “Warrants”) to purchase up to 13,703,876 shares of our common stock, par value $0.01 per share, and the shares of such common stock (the “Warrant Shares”) issuable upon the exercise of the Warrants, in each case, by the selling securityholder named herein from time to time.

On April 20, 2020 (the “PSP Closing Date”), American, Envoy Air Inc., Piedmont Airlines, Inc. and PSA Airlines, Inc., each a wholly-owned subsidiary of our company, entered into the PSP Agreement with Treasury, with respect to the Payroll Support Program under the CARES Act. In connection with our entry into the PSP Agreement, on the PSP Closing Date, we entered into a Warrant Agreement (the “Warrant Agreement”) with Treasury.

Pursuant to the PSP Agreement, Treasury provided us with financial assistance in the aggregate amount of approximately $5,815 million. As partial compensation to the U.S. Government for the provision of financial assistance under the Payroll Support Program, we issued the Warrants to Treasury pursuant to the Warrant Agreement. The initial exercise price of each Warrant Share is $12.51 (which was the closing price of our common stock on Nasdaq on April 9, 2020). The exercise price and the number of Warrant Shares to be issued are subject to adjustment as a result of certain anti-dilution provisions provided for in the Warrants.

We issued Warrants to Treasury on the PSP Closing Date, May 29, 2020, June 30, 2020 and July 30, 2020 with the right to purchase 6,732,034 Warrant Shares, 2,788,737 Warrant Shares, 2,788,737 Warrant Shares and 1,394,368 Warrant Shares, respectively. The Warrants are exercisable until the fifth anniversary of the issuance date of the applicable Warrant.

We agreed to register the resale of the Warrants and Warrant Shares pursuant to the Warrant Agreement.

Additionally, we may issue warrants to Treasury for up to approximately 38 million shares of our common stock, assuming we draw the full $4.75 billion principal amount of the secured loan pursuant to the CARES Act that is contemplated by a term sheet we have entered into with the Treasury.

The following tables set forth information as of July 31, 2020, with respect to the selling securityholder for whom we are registering Warrants and Warrant Shares for sale to the public, the number of shares of our common stock and Warrants owned by the selling securityholder prior to this offering, the percentage of common stock and Warrants owned by the selling securityholder prior to this offering, the number of Warrants and Warrant Shares being offered pursuant to this prospectus supplement, the number of shares of our common stock and Warrants to be owned upon completion of this offering, assuming all such Warrants and Warrant Shares are sold, and the percentage of common stock and Warrants owned by the selling securityholder after this offering, assuming all such Warrants and Warrant Shares are sold.

In the table below for the Warrant Shares, the number of Warrant Shares that may be offered pursuant to this prospectus supplement is the number of shares of common stock issuable pursuant to the Warrants. Pursuant to Rule 416 under the Securities Act, this prospectus supplement also covers any additional shares of our common stock that may become issuable in connection with the Warrant Shares by reason of a stock dividend, stock split or other similar transaction effected without us receiving any cash or other value, which results in an increase in the number of shares of our common stock outstanding.

As used in this prospectus supplement, the term “selling securityholder” includes the selling securityholder listed below, and any donees, pledgees, transferees or other successors in interest selling Warrant Shares received after the date of this prospectus supplement from the selling securityholder as a gift, pledge, or other non-sale related transfer. The number of shares in the column “Number of Warrant Shares Offered” represents all of the Warrant Shares that the selling securityholder may offer under this prospectus supplement. The number of Warrants in the column “Number of Warrants Offered” represents all of the Warrants that the selling

S-8

securityholder may offer under this prospectus supplement. The selling securityholder may sell some, all or none of its Warrants or Warrant Shares. The selling securityholder may sell or transfer all or a portion of its Warrants or Warrant Shares pursuant to an available exemption from the registration requirements of the Securities Act. We do not know how long the selling securityholder will hold the Warrants or Warrant Shares before selling them, and we currently have no agreements, arrangements or understandings with the selling securityholder regarding the sale of any of the Warrants or Warrant Shares. Pursuant to the Warrant Agreement, Treasury must provide 30 days’ notice to us prior to the sale of the Warrants or any portion thereof.

Beneficial ownership is determined in accordance with Rule 13d-3(d) promulgated by the SEC under the Exchange Act. The percentage of shares beneficially owned prior to the offering is based on 508,561,718 shares of our common stock outstanding as of July 31, 2020.

S-9

PLAN OF DISTRIBUTION

The selling securityholder and any of its donees, pledgees, transferees or other successors in interest may, from time to time, sell any or all of their Warrant Shares covered hereby on Nasdaq or sell any or all of their Warrant Shares or Warrants on any other stock exchange, market or trading facility on which such securities become tradeable or in private transactions. These sales may be at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices.

The selling securityholder will act independently of us in making decisions with respect to the timing, manner and size of each sale. Such sales may be made on one or more exchanges or in the over-the-counter market or otherwise, at prices and under terms then prevailing or at prices related to the then current market price or in negotiated transactions. However, there is no established public trading market for the Warrants and we do not intend to apply for listing of the Warrants on any securities exchange or recognized trading system. The price at which the Warrants may be sold will depend, in part, on the manner and timing of such sales, but, in any event, we expect such price will likely be derived from the market price of shares of our common stock traded on Nasdaq.

The selling securityholder may use any one or more of the following methods when selling the Warrants or Warrant Shares:

The selling securityholder may also sell Warrants or Warrant Shares under Rule 144 under the Securities Act, if available, rather than under this prospectus supplement.

Broker-dealers engaged by the selling securityholder may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling securityholder (or, if any broker-dealer acts as agent for the purchaser of Warrants or Warrant Shares, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus supplement, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with FINRA IM-2440-1.

In connection with the sale of the Warrants or Warrant Shares, the selling securityholder may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales

S-10

of the common stock in the course of hedging the positions they assume. The selling securityholder may also sell shares of our common stock short and deliver these securities to close out its short positions or to return borrowed shares in connection with such short sales, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling securityholder may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities, which require the delivery to such broker-dealer or other financial institution of Warrants or Warrant Shares offered by this prospectus supplement, which Warrants or Warrant Shares, as applicable, such broker-dealer or other financial institution may resell pursuant to this prospectus supplement (as supplemented or amended to reflect such transaction).

The selling securityholder and any broker-dealers or agents that are involved in selling the Warrants or Warrant Shares may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the Warrants or Warrant Shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.

We are required to pay certain fees and expenses incurred by us incident to the registration of the Warrants and Warrant Shares. We have agreed to indemnify the selling securityholder against certain losses, claims, damages, actions, liabilities, costs and expenses, including liabilities under the Securities Act, and the selling securityholder may be entitled to contribution.

The selling securityholder will be subject to the prospectus delivery requirements of the Securities Act including Rule 172 thereunder unless an exemption therefrom is available.

To our knowledge, there are currently no plans, arrangements or understandings between the selling securityholder and any underwriter, broker-dealer or agent regarding the sale by the selling securityholder of the Warrants or Warrant Shares.

We have agreed to use reasonable best efforts to keep the registration statement of which this prospectus supplement is a part (or a replacement) continuously effective and in compliance with the Securities Act until, subject to certain exceptions, the Warrants and Warrant Shares: (i) have been sold pursuant to an effective registration statement; (ii) are able to be sold pursuant to Rule 144 of the Securities Act without limitation on volume or manner of sale; (iii) cease to be outstanding; or (iv) have been sold in a private transaction in which the transferor’s rights under the Warrant Agreement are not assigned to the transferee of the securities.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the Warrants and Warrant Shares may not simultaneously engage in market making activities with respect to those securities for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling securityholder will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of Warrants and Warrant Shares by the selling securityholder or any other person. We will make copies of this prospectus supplement available to the selling securityholder and have informed them of the need to deliver a copy of this prospectus supplement to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

There can be no assurance that the selling securityholder will sell any or all of the Warrants or Warrant Shares registered pursuant to the registration statement, of which this prospectus supplement forms a part.

Once sold under the registration statement, of which this prospectus supplement forms a part, the Warrants and Warrant Shares will be freely tradable in the hands of persons other than our affiliates.

DESCRIPTION OF CAPITAL STOCK

The following description of AAG’s capital stock is not complete and may not contain all the information you should consider before investing in our capital stock. This description is summarized from, and qualified in its entirety by reference to, our certificate of incorporation and bylaws, which have been publicly filed with the SEC. See “Where You Can Find More Information; Incorporation by Reference.”

AAG’s authorized capital stock consists of:

Common Stock

Dividends

Holders of AAG common stock are entitled to receive dividends or other distributions in cash, stock or property of AAG when, as and if declared on the common stock by AAG’s board of directors from time to time out of assets or funds of AAG legally available therefor, subject to the rights of holders of any outstanding preferred stock.

Voting Rights

Holders of AAG common stock are entitled to one vote per share on all matters submitted to a vote of common stockholders, except that voting rights of non-U.S. citizens are limited as described below under “—Other Provisions Restricting Transfer and Ownership.” Holders of AAG common stock have no right to cumulate their votes.

Liquidation Rights

In the event of any voluntary or involuntary liquidation, dissolution, or winding up of AAG, holders of AAG common stock are entitled to receive the assets and funds legally available for distribution in proportion to the number of shares held by them after payments to creditors and of preferential amounts, if any, to which any holders of AAG preferred stock may be entitled. If AAG has any preferred stock outstanding at such time, holders of the preferred stock may be entitled to distributions and/or liquidation preferences. In such case, AAG must pay the applicable distribution to holders of its preferred stock, if required pursuant to the terms of any such preferred stock, before it may pay distributions to holders of AAG common stock.

Other Rights

In the event of a merger or consolidation of AAG with or into another entity, the holders of AAG common stock are entitled to receive the same per share consideration on a per share basis.

Holders of AAG’s common stock are not entitled to preemptive rights to purchase additional shares.

Transfer Agent

The transfer agent and registrar for AAG’s common stock is American Stock Transfer & Trust Company, LLC.

Preferred Stock

AAG’s certificate of incorporation authorizes the issuance of up to 200 million shares of preferred stock from time to time, in one or more series, with such voting powers, full or limited, or without voting powers and

5

with such designations, preferences, and relative, participating, optional, or other special rights, and qualifications, limitations, or restrictions thereof, as are stated and expressed in the resolution or resolutions providing for the issuance thereof adopted by AAG’s board of directors.

Holders of shares of AAG’s preferred stock are not entitled to preemptive rights to purchase additional shares.

Certain Anti-takeover Provisions of AAG’s Certificate of Incorporation and Bylaws

Certain provisions of AAG’s certificate of incorporation and bylaws may have the effect of delaying or preventing a change in control if AAG’s board of directors determines such change in control is not in the best interests of AAG and its stockholders. These provisions include, among other things, the following:

AAG is also subject to the provisions of Section 203 of the Delaware General Corporation Law. Under Section 203, we would generally be prohibited from engaging in any business combination with any interested stockholder for a period of three years following the time that such stockholder became an interested stockholder unless:

6

Under Section 203, a “business combination” includes:

In general, Section 203 defines an interested stockholder as an entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by such entity or person.

Other Provisions Restricting Transfer and Ownership

The AAG certificate of incorporation and bylaws also impose certain restrictions on the transferability and ownership of AAG common stock, preferred stock, warrants, rights or options to purchase AAG common stock and certain other equity-type interests of AAG, which we refer to collectively as AAG Securities, in order to comply with U.S. law and related rules and regulations of the U.S. Department of Transportation, which we refer to as the DOT, and to reduce the possibility that subsequent changes in the ownership of AAG Securities could result in limitations on the use of the significant deductions in any year for net operating losses carried over from prior taxable years, and other valuable income tax attributes of AAG and its subsidiaries.

Restrictions on Transfer

Subject to certain exceptions, or the prior approval of AAG’s board of directors, the AAG certificate of incorporation restricts any person or entity (including certain groups of persons) from directly or indirectly acquiring or accumulating AAG Securities if such person or entity would become a Substantial Stockholder, which the AAG certificate of incorporation defines generally as a person or entity with a percentage ownership of 4.75% or more of the outstanding capital stock of AAG or if such acquisition would increase the percentage stock ownership (as determined under applicable tax law principles) of a Substantial Stockholder. These restrictions may remain in effect until December 9, 2021 and may be waived by the board of directors of AAG on a case-by-case basis.

Foreign Ownership Limitations

The AAG certificate of incorporation and bylaws provide that, consistent with the requirements of Subtitle VII of Title 49 of the United States Code, as amended (the “Aviation Act”), any persons or entities who are not a “citizen of the United States” (as defined under the Aviation Act and administrative interpretations issued by the DOT, its predecessors and successors, from time to time), including any agent, trustee or representative of such persons or entities (a non-citizen), shall not, in the aggregate, own (beneficially or of record) and/or control more than (a) 24.9% of the aggregate votes of all of our outstanding equity securities or (b) 49.0% of our outstanding equity securities. The AAG certificate of incorporation and bylaws further specify that it is the duty of each stockholder who is a non-citizen to register his, her or its equity securities on our foreign stock record and provide for remedies applicable to stockholders that exceed the voting and ownership caps described above. In addition, any attempt to transfer AAG Securities to a non-U.S. person in excess of 49.0% of our outstanding equity securities will be void and of no effect and will not be recorded in our books and records.

DESCRIPTION OF DEBT SECURITIES

The following description, together with the additional information we include in any prospectus supplement or free writing prospectus, as applicable, summarizes certain general terms and provisions of the debt securities that we may offer under this prospectus. When we offer to sell one or more particular series of debt securities, we will describe the specific terms of such series in a supplement to this prospectus. We will also indicate in the supplement to what extent the general terms and provisions described in this prospectus apply to a particular series of debt securities.

We may issue debt securities either separately, or together with, or upon the conversion or exercise of or in exchange for, other securities described in this prospectus. Debt securities and guarantees, if any, may be our senior, senior subordinated or subordinated obligations and, unless otherwise specified in a supplement to this prospectus, the debt securities will be our direct, unsecured obligations and may be issued in one or more series. The debt securities issued by AAG may be fully and unconditionally guaranteed on a secured or unsecured, senior or subordinated basis by AAI or any of AAG’s other subsidiaries.

The debt securities will be issued under an indenture between us and Wilmington Trust, National Association, as trustee. We have summarized select portions of the indenture below. The summary is not complete. The form of the indenture has been filed as an exhibit to the registration statement and you should read the indenture for provisions that may be important to you. In the summary below, we have included references to the section numbers of the indenture so that you can easily locate these provisions. Capitalized terms used in the summary and not defined herein have the meanings specified in the indenture.

As used in this section only, “AAG,” “we,” “our” or “us” refer to American Airlines Group Inc. excluding our subsidiaries, unless expressly stated or the context otherwise requires, and “AAI” refers to American Airlines, Inc. excluding its subsidiaries, unless expressly stated or the context otherwise requires.

General

The terms of each series of debt securities will be established by or pursuant to a resolution of our board of directors and set forth or determined in the manner provided in a resolution of our board of directors, in an officer’s certificate or by a supplemental indenture. (Section 2.2) The particular terms of each series of debt securities will be described in a prospectus supplement relating to such series (including any pricing supplement or term sheet).

We can issue an unlimited amount of debt securities under the indenture that may be in one or more series with the same or various maturities, at par, at a premium, or at a discount. (Section 2.1) We will set forth in a prospectus supplement (including any pricing supplement or term sheet) relating to any series of debt securities being offered, the aggregate principal amount and the following terms of the debt securities, if applicable:

8

9

We may issue debt securities that provide for an amount less than their stated principal amount to be due and payable upon declaration of acceleration of their maturity pursuant to the terms of the indenture. We will provide you with information on the federal income tax considerations and other special considerations applicable to any of these debt securities in the applicable prospectus supplement.

If we denominate the purchase price of any of the debt securities in a foreign currency or currencies or a foreign currency unit or units, or if the principal of and any premium and interest on any series of debt securities is payable in a foreign currency or currencies or a foreign currency unit or units, we will provide you with information on the restrictions, elections, general tax considerations, specific terms and other information with respect to that issue of debt securities and such foreign currency or currencies or foreign currency unit or units in the applicable prospectus supplement.

Transfer and Exchange

Each debt security will be represented by either one or more global securities registered in the name of The Depository Trust Company, or the Depositary, or a nominee of the Depositary (we will refer to any debt security represented by a global debt security as a “book-entry debt security”), or a certificate issued in definitive registered form (we will refer to any debt security represented by a certificated security as a “certificated debt security”) as set forth in the applicable prospectus supplement. Except as set forth under the heading “Global Debt Securities and Book-Entry System” below, book-entry debt securities will not be issuable in certificated form.

Certificated Debt Securities. You may transfer or exchange certificated debt securities at any office we maintain for this purpose in accordance with the terms of the indenture. (Section 2.4) No service charge will be made for any transfer or exchange of certificated debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with a transfer or exchange. (Section 2.7)

You may effect the transfer of certificated debt securities and the right to receive the principal of, premium and interest on certificated debt securities only by surrendering the certificate representing those certificated debt securities and either reissuance by us or the trustee of the certificate to the new holder or the issuance by us or the trustee of a new certificate to the new holder.

Global Debt Securities and Book-Entry System. Each global debt security representing book-entry debt securities will be deposited with, or on behalf of, the Depositary, and registered in the name of the Depositary or a nominee of the Depositary. Please see “Global Securities.”

Covenants

We will set forth in the applicable prospectus supplement any restrictive covenants applicable to any issue of debt securities. (Article IV)

No Protection In the Event of a Change of Control

Unless we state otherwise in the applicable prospectus supplement, the debt securities will not contain any provisions which may afford holders of the debt securities protection in the event we have a change in control or in the event of a highly leveraged transaction (whether or not such transaction results in a change in control) which could adversely affect holders of debt securities.

10

Consolidation, Merger and Sale of Assets

We may not consolidate with or merge with or into, or convey, transfer or lease all or substantially all of our properties and assets to, any person (a “successor person”) unless:

Notwithstanding the above, any subsidiary of AAG may consolidate with, merge into or transfer all or part of its properties to AAG. (Section 5.1)

Events of Default

“Event of Default” means with respect to any series of debt securities, any of the following:

No Event of Default with respect to a particular series of debt securities (except as to certain events of bankruptcy, insolvency or reorganization) necessarily constitutes an Event of Default with respect to any other series of debt securities. (Section 6.1) The occurrence of certain Events of Default or an acceleration under the indenture may constitute an event of default under certain indebtedness of ours or our subsidiaries outstanding from time to time.

We will provide the trustee written notice of any Default or Event of Default within 30 days of becoming aware of the occurrence of such Default or Event of Default, which notice will describe in reasonable detail the status of such Default or Event of Default and what action we are taking or propose to take in respect thereof. (Section 6.1)

If an Event of Default with respect to debt securities of any series at the time outstanding occurs and is continuing, then the trustee or the holders of not less than 25% in principal amount of the outstanding debt securities of that series may, by a notice in writing to us (and to the trustee if given by the holders), declare to be due and payable immediately the principal of (or, if the debt securities of that series are discount securities, that portion of the principal amount as may be specified in the terms of that series) and accrued and unpaid interest, if any, on all debt securities of that series. In the case of an Event of Default resulting from certain events of bankruptcy, insolvency or reorganization, the principal (or such specified amount) of and accrued and unpaid

11

interest, if any, on all outstanding debt securities will become and be immediately due and payable without any declaration or other act on the part of the trustee or any holder of outstanding debt securities. At any time after a declaration of acceleration with respect to debt securities of any series has been made, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in principal amount of the outstanding debt securities of that series may rescind and annul the acceleration if all Events of Default, other than the non-payment of accelerated principal and interest, if any, with respect to debt securities of that series, have been cured or waived as provided in the indenture. (Section 6.2) We refer you to the prospectus supplement relating to any series of debt securities that are discount securities for the particular provisions relating to acceleration of a portion of the principal amount of such discount securities upon the occurrence of an Event of Default.

The indenture provides that the trustee may refuse to perform any duty or exercise any of its rights or powers under the indenture unless the trustee receives indemnity satisfactory to it against any cost, liability or expense which might be incurred by it in performing such duty or exercising such right or power. (Section 7.1(e)) Subject to certain rights of the trustee, the holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the debt securities of that series. (Section 6.12)

No holder of any debt security of any series will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture or for the appointment of a receiver or trustee, or for any remedy under the indenture, unless:

Notwithstanding any other provision in the indenture, the holder of any debt security will have an absolute and unconditional right to receive payment of the principal of, premium and any interest on that debt security on or after the due dates expressed in that debt security and to institute suit for the enforcement of payment. (Section 6.8)

The indenture requires us, within 120 days after the end of our fiscal year, to furnish to the trustee a statement as to compliance with the indenture. (Section 4.3) If a Default or Event of Default occurs and is continuing with respect to the securities of any series and if it is known to a responsible officer of the trustee, the trustee shall mail to each Securityholder of the securities of that series notice of a Default or Event of Default within 90 days after it occurs or, if later, after a responsible officer of the trustee has knowledge of such Default or Event of Default. The indenture provides that the trustee may withhold notice to the holders of debt securities of any series of any Default or Event of Default (except in payment on any debt securities of that series) with respect to debt securities of that series if the trustee determines in good faith that withholding notice is in the interest of the holders of those debt securities. (Section 7.5)

Modification and Waiver

We and the trustee may modify, amend or supplement the indenture or the debt securities of any series without the consent of any holder of any debt security:

12

We may also modify and amend the indenture with the consent of the holders of at least a majority in principal amount of the outstanding debt securities of each series affected by the modifications or amendments (with the securities of each series voting as a class). We may not make any modification or amendment without the consent of the holders of each affected debt security then outstanding if that amendment will:

Except for certain specified provisions, the holders of at least a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all debt securities of that series waive our compliance with provisions of the indenture. (Section 9.2) The holders of a majority in principal amount of

13

the outstanding debt securities of any series may on behalf of the holders of all the debt securities of such series waive any past default under the indenture with respect to that series and its consequences, except a default in the payment of the principal of, premium or any interest on any debt security of that series; provided, however, that the holders of a majority in principal amount of the outstanding debt securities of any series may rescind an acceleration and its consequences, including any related payment default that resulted from the acceleration. (Section 6.13)

Defeasance of Debt Securities and Certain Covenants in Certain Circumstances

Legal Defeasance. The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, we may be discharged from any and all obligations in respect of the debt securities of any series (subject to certain exceptions). We will be so discharged upon the irrevocable deposit with the trustee, in trust, of money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. Dollars, government obligations of the government that issued or caused to be issued such currency, that, through the payment of interest and principal in accordance with their terms, will provide money or U.S. government obligations in an amount sufficient in the opinion of a nationally recognized firm of independent public accountants or investment bank to pay and discharge each installment of principal, premium and interest on and any mandatory sinking fund payments in respect of the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities.

This discharge may occur only if, among other things, we have delivered to the trustee an opinion of counsel stating that we have received from, or there has been published by, the United States Internal Revenue Service a ruling or, since the date of execution of the indenture, there has been a change in the applicable United States federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the holders of the debt securities of that series will not recognize income, gain or loss for United States federal income tax purposes as a result of the deposit, defeasance and discharge and will be subject to United States federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit, defeasance and discharge had not occurred. (Section 8.3)

Defeasance of Certain Covenants. The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, upon compliance with certain conditions:

The conditions include:

14

No Personal Liability of Directors, Officers, Employees or Stockholders

None of our past, present or future directors, officers, employees or stockholders, as such, will have any liability for any of our obligations under the debt securities or the indenture or for any claim based on, or in respect or by reason of, such obligations or their creation. By accepting a debt security, each holder waives and releases all such liability. This waiver and release is part of the consideration for the issue of the debt securities. However, this waiver and release may not be effective to waive liabilities under U.S. federal securities laws, and it is the view of the SEC that such a waiver is against public policy.

Governing Law

GLOBAL SECURITIES

Book-Entry, Delivery and Form

Unless we indicate differently in any applicable prospectus supplement or free writing prospectus, the securities initially will be issued in book-entry form and represented by one or more global notes or global securities, or, collectively, global securities. The global securities will be deposited with, or on behalf of, The Depository Trust Company, New York, New York, as depositary, or DTC, and registered in the name of Cede & Co., the nominee of DTC. Unless and until it is exchanged for individual certificates evidencing securities under the limited circumstances described below, a global security may not be transferred except as a whole by the depositary to its nominee or by the nominee to the depositary, or by the depositary or its nominee to a successor depositary or to a nominee of the successor depositary.

DTC has advised us that it is:

DTC holds securities that its participants deposit with DTC. DTC also facilitates the settlement among its participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, thereby eliminating the need for physical movement of securities certificates. “Direct participants” in DTC include securities brokers and dealers, including underwriters, banks, trust companies, clearing corporations and other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation, or DTCC. DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others, which we sometimes refer to as indirect participants, that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. The rules applicable to DTC and its participants are on file with the SEC.

Purchases of securities under the DTC system must be made by or through direct participants, which will receive a credit for the securities on DTC’s records. The ownership interest of the actual purchaser of a security, which we sometimes refer to as a beneficial owner, is in turn recorded on the direct and indirect participants’ records. Beneficial owners of securities will not receive written confirmation from DTC of their purchases. However, beneficial owners are expected to receive written confirmations providing details of their transactions, as well as periodic statements of their holdings, from the direct or indirect participants through which they purchased securities. Transfers of ownership interests in global securities are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the global securities, except under the limited circumstances described below.

To facilitate subsequent transfers, all global securities deposited by direct participants with DTC will be registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of securities with DTC and their registration in the name of Cede & Co. or such other nominee will not change the beneficial ownership of the securities. DTC has no knowledge of the actual beneficial owners of the securities. DTC’s records reflect only the identity of the direct participants to whose accounts the securities are credited, which may or may not be the beneficial owners. The participants are responsible for keeping account of their holdings on behalf of their customers.

17

So long as the securities are in book-entry form, you will receive payments and may transfer securities only through the facilities of the depositary and its direct and indirect participants. We will maintain an office or agency in the location specified in the prospectus supplement for the applicable securities, where notices and demands in respect of the securities and the indenture may be delivered to us and where certificated securities may be surrendered for payment, registration of transfer or exchange.

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any legal requirements in effect from time to time.

Redemption notices will be sent to DTC. If less than all of the securities of a particular series are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participant in the securities of such series to be redeemed.

Neither DTC nor Cede & Co. (or such other DTC nominee) will consent or vote with respect to the securities. Under its usual procedures, DTC will mail an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns the consenting or voting rights of Cede & Co. to those direct participants to whose accounts the securities of such series are credited on the record date, identified in a listing attached to the omnibus proxy.

So long as securities are in book-entry form, we will make payments on those securities to the depositary or its nominee, as the registered owner of such securities, by wire transfer of immediately available funds. If securities are issued in definitive certificated form under the limited circumstances described below and unless otherwise provided in the description of the applicable securities herein or in the applicable prospectus supplement, we will have the option of making payments by check mailed to the addresses of the persons entitled to payment or by wire transfer to bank accounts in the United States designated in writing to the applicable trustee or other designated party at least 15 days before the applicable payment date by the persons entitled to payment, unless a shorter period is satisfactory to the applicable trustee or other designated party.

Redemption proceeds, distributions and dividend payments, as applicable, on the securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit direct participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us on the payment date in accordance with their respective holdings shown on DTC records. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the account of customers in bearer form or registered in “street name.” Those payments will be the responsibility of participants and not of DTC or us, subject to any statutory or regulatory requirements in effect from time to time. Payment of redemption proceeds, distributions and dividend payments to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC, is our responsibility; disbursement of payments to direct participants is the responsibility of DTC; and disbursement of payments to the beneficial owners is the responsibility of direct and indirect participants.

Except under the limited circumstances described below, purchasers of securities will not be entitled to have securities registered in their names and will not receive physical delivery of securities. Accordingly, each beneficial owner must rely on the procedures of DTC and its participants to exercise any rights under the securities and the indenture.

The laws of some jurisdictions may require that some purchasers of securities take physical delivery of securities in definitive form. Those laws may impair the ability to transfer or pledge beneficial interests in securities.

DTC may discontinue providing its services as securities depositary with respect to the securities at any time by giving reasonable notice to us. Under such circumstances, in the event that a successor depositary is not

18

obtained, securities certificates are required to be printed and delivered to the holders of beneficial interests in the securities.

As noted above, beneficial owners of a particular series of securities generally will not receive certificates representing their ownership interests in those securities. However, if:

we will prepare and deliver certificates for such securities in exchange for beneficial interests in the global securities. Any beneficial interest in a global security that is exchangeable under the circumstances described in the preceding sentence will be exchangeable for securities in definitive certificated form registered in the names that the depositary directs. It is expected that these directions will be based upon directions received by the depositary from its participants with respect to ownership of beneficial interests in the global securities.

Euroclear and Clearstream

If so provided in the applicable prospectus supplement, you may hold interests in a global security through Clearstream Banking S.A., which we refer to as “Clearstream,” or Euroclear Bank S.A./N.V., as operator of the Euroclear System, which we refer to as “Euroclear,” either directly if you are a participant in Clearstream or Euroclear, or indirectly through organizations which are participants in Clearstream or Euroclear. Clearstream and Euroclear will hold interests on behalf of their respective participants through customers’ securities accounts in the names of Clearstream and Euroclear, respectively, on the books of their respective U.S. depositaries, which in turn will hold such interests in customers’ securities accounts in such depositaries’ names on DTC’s books.

Clearstream and Euroclear are securities clearance systems in Europe. Clearstream and Euroclear hold securities for their respective participating organizations and facilitate the clearance and settlement of securities transactions between those participants through electronic book-entry changes in their accounts, thereby eliminating the need for physical movement of certificates.

Payments, deliveries, transfers, exchanges, notices and other matters relating to beneficial interests in global securities owned through Euroclear or Clearstream must comply with the rules and procedures of those systems. Transactions between participants in Euroclear or Clearstream, on one hand, and other participants in DTC, on the other hand, are also subject to DTC’s rules and procedures.

Investors will be able to make and receive through Euroclear and Clearstream payments, deliveries, transfers and other transactions involving any beneficial interests in global securities held through those systems only on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States.

Cross-market transfers between participants in DTC, on the one hand, and participants in Euroclear or Clearstream, on the other hand, will be effected through DTC in accordance with the DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by their respective U.S. depositaries; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines

19

(European time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the global securities through DTC, and making or receiving payment in accordance with normal procedures for same-day fund settlement. Participants in Euroclear or Clearstream may not deliver instructions directly to their respective U.S. depositaries.

Due to time zone differences, the securities accounts of a participant in Euroclear or Clearstream purchasing an interest in a global security from a direct participant in DTC will be credited, and any such crediting will be reported to the relevant participant in Euroclear or Clearstream, during the securities settlement processing day (which must be a business day for Euroclear or Clearstream) immediately following the settlement date of DTC. Cash received in Euroclear or Clearstream as a result of sales of interests in a global security by or through a participant in Euroclear or Clearstream to a direct participant in DTC will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC’s settlement date.
