MILEAGE PLUS TO BE THE LOYALTY PROGRAM FOR THE NEW UNITED AIRLINES

MEMBERS OF CONTINENTAL’S ONEPASS TO BE AUTO-ENROLLED FOR 2012

CHICAGO, June 29, 2011 - United Continental Holdings, Inc. (NYSE: UAL) today announced that Mileage Plus will be the loyalty program for its wholly owned subsidiaries United Airlines and Continental Airlines beginning in 2012. Moving to a single loyalty program is a significant milestone in the integration of the two airlines and will provide a more consistent travel experience for customers.

United will announce complete details of the Mileage Plus program – including elite levels, qualifications and benefits, lifetime benefits, and other program developments that will take effect in 2012 – in the coming months.

Continental OnePass miles and status safe

Continental’s OnePass loyalty program will end on Dec. 31, 2011. United will automatically enroll OnePass members in Mileage Plus and deposit into Mileage Plus award miles equal to their OnePass award miles balance. OnePass members’ 2011 OnePass elite qualifying activity will be recognized fully in their 2012 Mileage Plus elite status. Chase OnePass credit cards, including OnePass Plus and Presidential Plus, will continue to earn miles and benefits in the Mileage Plus program.

In the meantime, United and Continental customers who are currently enrolled in both Mileage Plus and OnePass may link their accounts, enabling them to combine their miles and earn awards faster this year.

Launched in 1981, Mileage Plus is the world’s most rewarding loyalty program, with a wide array of travel, credit card and retail partners. Mileage Plus members may earn elite travel benefits, including Premier Access airport services, and have access to one of the most extensive merchandise redemption programs in the industry. With the new United’s leading global route network, no other airline offers more destinations for award travel.

Mileage Plus received the Frequent Traveler award for best airline elite program in 2011, the second year in a row. In addition, readers of Global Traveler magazine voted Mileage Plus best frequent flyer program in 2010 for the seventh year in a row.
