PRNewswire-FirstCall PHOENIX Nov. 26 :

America West announced today that it has initiated the only nonstop
service between Las Vegas and Billings, Mont. America West Express, which
is operated by Mesa Airlines, will provide the daily flights using the
50-seat Canadair Regional Jet.
This new service gives business and leisure travelers even more
opportunity to take advantage of America West`s business-friendly fares
which are 50 to 75 percent lower than most other major airlines and do not
require a Saturday night stay.

“We`ve received outstanding customer support for our flights between
Phoenix and Billings, so we`re pleased to be adding service to our hub in
Las Vegas, which is also a popular vacation destination,” said Dion
Flannery, vice president, scheduling, route planning and Internet
distribution. “Customers can also connect through both hubs to dozens of
destinations in the U.S., Mexico and as of Dec. 1, to San Jose, Costa
Rica.”

On Oct. 26, America West initiated new service between Las Vegas and St.
Louis and on Dec. 19 the airline will initiate new service between Las
Vegas and Des Moines, Iowa. America West also plans to add additional
flights between Las Vegas and the following cities, which will begin on
