US Airways 8-K Results of Operations and Financial Condition

Exhibit 99.1

INVESTOR RELATIONS UPDATE
January 5, 2011

General Comments

• 2010 Capacity Guidance— For 2010, total system capacity is expected to be up slightly. Mainline is forecast to be up approximately one percent, with domestic down approximately one percent and international up approximately eight percent. Express is expected to be down approximately one percent.

• Cash— As of September 30, 2010, the Company had approximately $2.4 billion in total cash and investments, of which $389 million was restricted. In addition, as of September 30, 2010, the Company’s auction rate securities had a book value of $59 million ($93 million par value). While these securities are held as investments in non-current marketable securities on our balance sheet, they are included in our unrestricted cash calculation.

The Company expects to end the fourth quarter with approximately $2.3 billion of total cash and investments, of which $365 million is restricted.

• Fuel— For the fourth quarter 2010, the Company anticipates paying between $2.38 and $2.43 per gallon of mainline jet fuel (including taxes). Forecasted volume and fuel prices are provided in the table below.

• Profit Sharing / CASM— Profit sharing equals 10% of pre-tax earnings excluding special items up to a 10% pre-tax margin and 15% above the 10% margin. Profit sharing is excluded in the CASM guidance given below.

• Cargo / Other Revenue— Cargo revenue, ticket change fees, excess / overweight baggage fees, first and second bag fees, contract services, simulator rental, airport clubs, Materials Services Company (MSC), and inflight service revenues. The Company’s a la carte revenue initiatives are expected to generate in excess of $500 million in revenue in 2010.

• Taxes / NOL— As of December 31, 2009, net operating losses (NOL) available for use by the Company is approximately $2.1 billion, all of which is expected to be available for use in 2010. The Company’s net deferred tax asset, which includes the NOL, is subject to a full valuation allowance. As of December 31, 2009, the valuation allowances associated with Federal and state NOL are $546 million and $77 million, respectively. In accordance with generally accepted accounting principles, future utilization of the NOL will result in a corresponding decrease in the valuation allowance and offset the Company’s tax provision dollar for dollar. As a result, income tax benefits are not recognized in the Company’s statement of operations.

For the full year 2010, the Company expects to be profitable and will use NOL to reduce its federal and state income tax obligation. The Company’s full year state income tax obligation related to certain states where use of NOL is restricted is expected to approximate $1 million. The Company does not expect to be subject to AMT Liability in 2010 as a result of certain elections the Company made under the Worker, Homeownership, and Business Assistance Act of 2009.

GAAP to Non-GAAP RECONCILIATION
January 5, 2011

Reconciliation of GAAP to Non-GAAP Financial Information

US Airways Group, Inc. (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 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.

This update contains forward-looking statements that are not limited to historical facts, but reflect the Company’s current beliefs, expectations or intentions regarding future events. All forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from those in the forward-looking statements. For examples of such risks and uncertainties, please see the risk factors set forth in the Company’s Form 10-Q for the quarter ended September 30, 2010, and its other securities filings, including any amendments thereto, which identify important matters such as the consequences of fuel costs, labor costs, competition, and industry conditions, including the demand for air travel, the airline pricing environment and industry capacity decisions, regulatory matters and the seasonal nature of the airline business. The Company undertakes no obligation to publicly update or revise any forward-looking statements to reflect events or circumstances that may arise after the date of this update.
