Exhibit 99.1

INVESTOR RELATIONS UPDATE

October 3, 2013

General Comments

In July, the Company repaid in full the Barclays prepaid miles at their face amount of $200 million. The Company expects to end the third quarter with approximately $3.85 billion in total cash and investments of which approximately $350 million is restricted.

At June 30, 2013, NOLs available for use by the Company were approximately $1.1 billion for federal income tax purposes. To the extent profitable in 2013, the Company expects to continue to record federal non-cash income tax expense for financial reporting purposes. The Company currently estimates that its effective tax rate on future earnings excluding special items will approximate 36% for the third quarter, and 38% for the fourth quarter and beyond. This effective tax rate includes federal and state income taxes and takes into account the permanent differences between book income and taxable income. Notwithstanding such a book provision for federal income taxes, the income tax NOL described above is expected to be available to avoid the obligation to pay cash federal income taxes until it is fully consumed.

The Company may be obligated to record and pay state income tax related to certain states where NOLs may be limited or not available to be used. The Company recorded $2 million of state income tax expense in the second quarter of 2013. Additionally, when profitable the Company is ordinarily subject to AMT. However as the result of a special tax election made in 2009, the Company expects to be able to utilize AMT NOLs to offset AMT taxable income, if profitable in 2013.

As previously announced, in conjunction with execution of the Merger Agreement with AMR Corporation, US Airways Group adopted a tax benefit preservation plan designed to help preserve the value of the net operating losses and other deferred tax benefits of US Airways Group and the combined enterprise resulting from the merger with AMR. US Airways Group shareholders with ownership positions near or above the 4.9% threshold specified in the tax benefit preservation plan are urged to review its terms carefully. Further details about the plan are contained in a Form 8-K filed on February 14, 2013 by US Airways Group with the Securities and Exchange Commission.

2013 GAAP to Non-GAAP RECONCILIATION

October 3, 2013

Reconciliation of GAAP to Non-GAAP Financial Information

The Company is providing disclosure of the reconciliation of reported non-GAAP financial measures to their comparable financial measures on a GAAP basis. The Company believes that the non-GAAP financial measures provide investors the ability to measure financial performance excluding special items and profit sharing, which is more indicative of the Company’s ongoing performance and is more comparable to measures reported by other major airlines. The Company believes that the presentation of mainline CASM excluding fuel, special items & profit sharing and Express CASM excluding fuel and special items is useful to investors as both the cost and availability of fuel are subject to many economic and political factors beyond the Company’s control.

Notes: Amounts may not recalculate due to rounding.
