United Issues Travel Waiver for Customers Affected by Today's Delays and Cancellations

CHICAGO, April 2, 2008 /PRNewswire-FirstCall/ -- United customers who are traveling today and tomorrow on a United Boeing 777 aircraft may take advantage of its travel waiver and consider changing their travel plans, as certain change fees have been waived.

United flies its Boeing 777 aircraft on many international routes and some domestic routes between its hubs in Denver, Chicago, Los Angeles, San Francisco and Washington Dulles. Customers may log on to united.com, call United reservations at 1-800-UNITED-1 or a travel agency to determine what type of aircraft they are flying on and to make changes to their itineraries.

Customers with already canceled flights are eligible for a full refund.

We apologize for any inconvenience and ask customers to check their flight status on united.com before leaving for the airport. United is currently working to provide additional aircraft where available and is accommodating customers on other flights and other airlines.

Earlier today, United Airlines informed customers traveling on April 2, 2008 on United's Boeing 777 aircraft that they will experience flight delays or cancellations as a result of a functional check being performed on the aircraft.

As part of a regular review of maintenance records, the company discovered that the functional test that checks the firing system on one of the five bottles in the cargo fire suppression system on the Boeing 777 was not performed, and this was voluntarily disclosed to the FAA. United is in the process of checking this part of the system. This system is regularly tested as part of the pre-flight safety checks.

These checks are related to compliance. United will not operate these aircraft until the tests are complete.

United will conduct the check on all 52 Boeing 777 aircraft in the company's fleet.
