Chicago, IL, and Arlington, VA, (May 24, 2000) - UAL Corporation [NYSE: UAL] and
US Airways Group, Inc. [NYSE: U] today announced that their boards of directors have approved a definitive merger agreement pursuant to which US Airways will be acquired by United in an all-cash transaction valued at $4.3 billion (plus the assumption of $1.5 billion in net debt and $5.8 billion in aircraft operating leases).

Structure – Terms

Under the agreement, each share of common stock of US Airways will be converted into the right to receive $60.00 in cash in a one-step merger transaction. Based upon US Airways’ closing price of $26.31 on May 23, 2000, this represents a premium of about 130 percent to US Airways stockholders. The companies anticipate that the transaction will be completed in 2001. The combination will be accounted for as a purchase and is anticipated to be accretive to United’s earnings per share in the second year following the closing.

In recognition of the competitive issues connected with this transaction, United also plans to divest significant assets to maintain and enhance airline competition on routes into and out of Washington, DC. In connection with this planned divestiture, United and US Airways have entered into a Memorandum of Understanding with Robert Johnson, under which Mr. Johnson would buy certain of US Airways’ assets and create a new airline. This new carrier, to be called DC Air, will be the first significant new entrant at capacity-controlled Washington Reagan National Airport in over a decade. United would retain certain assets at Washington Reagan, including the US Airways Shuttle service to New York and Boston and the assets necessary for United to fly to Pittsburgh, Charlotte and Philadelphia from Washington Reagan.

The Combined Company - Unparalleled Convenience:

The combination of United and US Airways will deliver significant benefits to millions of passengers and hundreds of communities throughout the United States. The new network will make traveling more convenient for passengers, connecting US Airways’ eastern U.S. markets with United’s east-west and international networks. It will also give United passengers easier access to US Airways’ eastern United States network. Passengers will benefit from the convenience of one-airline, one-baggage check-in and one frequent flyer program.

•  United will offer "seamless" one-ticket, one-airline service on over 560 new city pairs – travelers will be able to fly without the inconvenience of changing airlines. There will also be fewer check-ins and baggage transfers.
•  Many US Airways cities will gain easier access to international destinations, strengthening their ability to attract international investment.
•  Travelers will be able to combine frequent flyer miles accumulated in both airline programs into United’s program. Passengers who now earn frequent flyer miles on two carriers will be able to consolidate their miles on United. This offers the opportunity to earn travel awards to more destinations in more countries than any other airline program offers.
•  Passengers will also benefit from United’s partnership with Star Alliance member airlines – Air Canada, Air New Zealand, All Nippon Airways, Ansett Australia, Lufthansa, SAS, Singapore Airlines, Thai Airways and VARIG. This will make international travel much simpler, with one-ticket booking, convenient baggage transfers and easier check-in.
•  United passengers will have the convenience of accruing United frequent flyer miles on the US Airways Shuttle. Shuttle users will be able to redeem their miles on United’s unmatched international network.
The Combined Company - Unparalleled Service:

United plans to serve all cities now served by US Airways. United plans to also offer 64 new daily non-stop flights in the U.S. and 29 new daily international flights. Passengers will benefit from more non-stop domestic flights. For example:

•  From Pittsburgh, United plans to introduce the only daily non-stop service to San Jose, CA and Portland, OR and add two non-stops a day to Denver.
•  From Philadelphia, United plans to offer the only daily non-stop service to San Jose, CA, Portland, OR and Orange County, CA.
•  From Charlotte, United plans to introduce the only daily non-stop service to Portland, OR, and San Antonio, TX.
•  From Washington Dulles, United plans to introduce the only daily non-stop service to Orange County, CA.
•  From Tampa, United plans to provide the only daily non-stop service to San Francisco.
Passengers will also benefit from more flights to Europe, Asia, Latin America and the Caribbean. Some examples of these flights include:

•  From Pittsburgh, United plans to introduce new one-stop service to significant Asian capitals, such as Beijing, Tokyo, Seoul and Singapore, as well as to Buenos Aires, Rio de Janeiro and other Latin American cities.
•  From Washington Dulles, United plans to add the only daily non-stop flights to Copenhagen and Bermuda.
•  From Philadelphia, United plans to introduce the only non-stop service to four international destinations - Amsterdam, Brussels, Vancouver and Barbados. United also plans to offer additional daily non-stop service to Frankfurt, Germany.
•  From Charlotte, United plans to provide the only one-stop service to Melbourne and Sydney, Australia; Auckland, New Zealand; Taipei, and Seoul and new one-stop service from Charlotte to Caracas, Rio de Janeiro, Sao Paulo, Buenos Aires and Santiago.
The transaction will significantly enhance the ability of US Airways hubs in Pittsburgh, Philadelphia and Charlotte to grow and compete with other hubs and international gateways, giving passengers easier access to the West and to destinations in Latin America, Asia and Europe.

United is committing that it will not increase U.S. point-to-point structure fares for two years following the closing of the merger, with exceptions only for increases in fuel cost and consumer price index (CPI).

United is also committing that for two years following completion of the merger, travel agents are guaranteed no reduction in domestic standard base commission rates.

Following the transaction, US Airways’ facilities, routes, equipment and personnel will operate under the United Airlines name. The combined company would have approximately
145,000 employees worldwide. This combination would create a global airline with revenue in excess of $25 billion.

James E. Goodwin, chairman and chief executive officer of UAL Corporation, said, "This combination provides significant benefits to the communities and customers served by both companies. The addition of US Airways will greatly improve United’s ability to serve customers in the East and to open its worldwide network to them. Similarly, the combination creates more travel options and convenience for Star Alliance passengers who travel to the cities US Airways serves. As the first carrier with a strong presence across the U.S., United will be positioned to provide a competitive challenge in new areas. We have the financial strength and unencumbered assets to continue to grow the company."

Mr. Goodwin continued, "For the passenger and cargo customers of United, this merger will fill a geographic void along the East coast and offers new reach to the East and Southeast. It also will provide new competition to others currently serving those regions. US Airways’ system will allow United to serve Trans-Atlantic, Latin American and Caribbean routes more effectively, intensifying competition in those markets, and will improve our ability to reach Asian destinations from across the U.S. This combination will also allow us to enhance our code-sharing alliance, with our Star Alliance partners, particularly across the Atlantic, making use of US Airways’ Pittsburgh, Philadelphia and Charlotte hubs. Together, we will be able to upgrade service and access to the world for our customers. Our customers will be linked to a system that will directly carry them to the commercial centers of the world. In short, United and US Airways together will create a more efficient global airline network that can improve the quality of service for its customers.

"We welcome the US Airways employees who will be joining the United family. Both United and US Airways employees are known for their commitment to service and professionalism. We look forward to offering them additional opportunity in the combined company. In addition, United intends to honor all union contracts, and this transaction will not result in any furloughs of United or US Airways employees," Mr. Goodwin added.

Stephen M. Wolf, chairman of US Airways Group, Inc., said, "The agreement we are announcing today, in which United and US Airways will merge, is a milestone in aviation history, melding the route systems and assets of two proud and successful carriers into this nation’s and the world’s largest and most comprehensive airline network. During the past four years, working closely with the 40,000 dedicated employees at US Airways, we have made enormous strides toward achieving our aim of becoming the carrier of choice. Today we have the opportunity to achieve our goal of becoming a world-class global carrier in a single stroke.

"By joining US Airways with United, we deliver value for our stockholders, provide dramatically improved global service for customers and achieve long-term security and career opportunities for US Airways’ employees. This is the right combination, the right partner, the right time and the right step for our customers, communities, shareholders and our employees," Mr. Wolf added.

Memorandum of Understanding to Divest Assets to Create a New Carrier

United proposes to address potential competitive issues related to the transaction in Washington DC by divesting sufficient assets to create another airline to compete in numerous routes currently served by US Airways in the Washington, DC area. In connection with this planned divestiture, United and US Airways have entered into a Memorandum of Understanding under which Robert Johnson would buy certain assets and create a new carrier to be called DC Air. This divestiture of assets will ensure that competition is maintained and enhanced and further consumer benefits will result from the merger.

The sale would include most of US Airways’ assets and route structure operating from Washington Reagan National Airport. These assets would create a base of operations for the new carrier out of Washington Reagan.

Mr. Johnson is the founder, chairman and chief executive officer of BET Holdings II, Inc., and a member of the US Airways Board.

Dividend

The transaction is not expected to affect United’s recently instituted annual dividend of
$1.25 per share of common stock.

The merger is conditioned upon, among other things, the approvals of US Airways stockholders, regulatory clearance and other customary closing conditions.
