EXHIBIT 99.1

INVESTOR RELATIONS UPDATE
January 30, 2007

General Comments

•	Profit Sharing / CASM —Profit sharing equals 10% of pre-tax earnings excluding transition expenses and special items up to a 10% pre-tax margin and 15% above the 10% margin. Profit sharing is included in the CASM guidance given below.
•	Cargo / Other Revenue —Cargo / Other Revenue includes: cargo revenue, ticket change fees, excess/overweight baggage fees, contract services, simulator rental, airport clubs, Materials Service Corporation (MSC), and inflight service revenues.
•	Fuel —US Airways uses costless collars on Heating Oil Futures as a fuel-hedging vehicle. For Q107, the Company has 56% of its mainline fuel hedged, and expects to pay between $1.98 and $2.03 per gallon of jet fuel (including taxes and hedges). The collar range of the hedges in place is between $1.88 and $2.08 per gallon of heating oil, or between $64.66 and $73.06 per barrel of crude oil. Forecasted volume, fuel prices, hedge percentages, and equivalent price per barrel of crude oil are provided in the table below.
•	Taxes / NOLs —As of December 31, 2006, US Airways and America West had a total of approximately $900 million of net operating loss carryforwards (NOL) to reduce future taxable income. Of this amount approximately $700 million is available to reduce federal taxable income in the calendar year 2007. The Company’s deferred tax asset, which includes the $700 million of NOL discussed above, has been subject to a valuation allowance. As of December 31, 2006, that valuation allowance was approximately $250 million.
	For the full year 2006, US Airways recognized $85 million of non cash income tax expense, as the Company utilized NOL that was generated by US Airways prior to the merger. Of this amount $26 million was recorded in the fourth quarter. In accordance with SFAS No. 109, as this was acquired NOL, the decrease in the valuation allowance associated with this NOL reduced goodwill instead of the provision for income taxes. As of December 31, 2006, the remaining valuation allowance associated with acquired NOL was approximately $30 million.
	The Company was subject to Alternative Minimum Tax liability (“AMT”) in 2006. In most cases the recognition of AMT does not result in tax expense. However, since the Company’s NOL was subject to a full valuation allowance, any liability for AMT is recorded as tax expense. The Company recorded AMT tax expense of $10 million for the full year 2006 of which $4 million was recorded in the fourth quarter. The Company also recorded $3 million of state income tax in the fourth quarter of 2006 related to certain states where NOL was limited or not available to be used.
	The Company again will use NOL to reduce taxable income in 2007. In Q107 and Q207, the Company expects the reversal of AWA’s remaining valuation allowance, which was established through the recognition of tax expense, will be recognized as a reduction of tax expense. In Q307 and Q407 the Company expects to recognize non-cash tax expense associated with the use of NOL, as the balance of valuation allowance should be reduced to zero.
	The Company also expects to be subject to AMT liability and to record and pay certain state income tax in 2007. Current estimates are less than $5 million per quarter.
•	Share Count —At the end of Q406, the Company had 89.9 million basic, and 91.9 million diluted weighted average shares outstanding. Both basic and diluted shares guidance is provided in the table below.
•	Cash —At the end of 2006, the Company had approximately $3.0 billion in total cash, of which $2.4 billion was unrestricted.

GAAP to Non-GAAP RECONCILIATION
January 30, 2007

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, 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 & transition expense 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, 2006, and its other securities filings, including any amendments thereto, which identify important matters such as the consequences of fuel, 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.
