On September 25, 2014, American Airlines Group Inc., a Delaware corporation (the “Company” or “AAG”), completed its previously announced offering of $750 million aggregate principal amount of 5.50% Senior Notes due 2019 (the “Notes”). The obligations of AAG under the Notes are fully and unconditionally guaranteed by its direct wholly-owned subsidiaries, American Airlines, Inc. and US Airways Group, Inc., and its indirect wholly-owned subsidiary, US Airways, Inc. (collectively, the “Guarantors”). The Notes were issued pursuant to an indenture, dated as of September 25, 2014 (the “Indenture”), by and among the Company, the Guarantors and Wilmington Trust, National Association, as trustee (the “Trustee”). The Notes were offered and sold only to persons reasonably believed to be qualified institutional buyers, as defined in, and in reliance on, Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to certain non-U.S. persons in transactions outside the United States in reliance on Regulation S under the Securities Act.

Interest on the Notes is payable semiannually in arrears on April 1 and October 1 of each year, beginning on April 1, 2015. The Notes will mature on October 1, 2019.

The Notes will be AAG’s senior unsecured obligations and the note guarantees will be the senior unsecured obligations of each Guarantor. The Notes and the note guarantees will rank pari passu in right of payment with AAG’s and each Guarantor’s respective existing and future senior indebtedness and senior in right of payment to AAG’s and each Guarantor’s respective future subordinated indebtedness. The Notes and the note guarantees will be effectively subordinated to AAG’s and each Guarantor’s respective existing and future secured indebtedness to the extent of the value of the assets pledged to secure those obligations. The Notes will also be structurally subordinated to all existing and future indebtedness of AAG’s non-guarantor subsidiaries.

If the Company experiences specific kinds of changes of control, the Company must offer to repurchase the Notes from holders at a price of 101% of the principal amount plus accrued and unpaid interest, if any, to the repurchase date.

The Indenture contains covenants that, among other things, restrict the ability of the Company and the ability of its restricted subsidiaries to: (i) pay dividends, redeem or repurchase stock or make other distributions or restricted payments, (ii) repay subordinated indebtedness, (iii) make certain loans and investments, (iv) incur indebtedness or issue preferred stock, (v) merge, consolidate or sell assets, (vi) undergo certain change of control transactions, and (vii) designate subsidiaries as unrestricted. These covenants are subject to a number of important exceptions and qualifications set forth in the Indenture.

Upon the occurrence of any event of default (other than certain bankruptcy or insolvency events affecting the Company or certain of its subsidiaries), the Trustee or the holders of at least 25% in aggregate principal amount of the outstanding Notes may declare all the Notes to be due and payable immediately. Upon the occurrence of certain bankruptcy or insolvency events affecting the Company or certain of its subsidiaries, all outstanding Notes will become due and payable immediately without further action or notice on the part of the Trustee or any holder.

Copies of the Indenture and the form of the Notes are filed herewith as Exhibits 4.1 and 4.2, respectively, and are incorporated by reference herein. The foregoing descriptions of the Indenture and the Notes are qualified in their entirety by reference to such exhibits.

The description set forth under Item 1.01 of this Form 8-K is incorporated by reference herein in its entirety.
