regional jet operated by
Mesa Airlines at the Las Vegas airport. America West Express started as a regional carrier in association with America West Airlines with a hub at Sky Harbor International Airport in Phoenix, Arizona. The name "America West Express" was taken from the old America West Airlines cargo service which had begun in 1985. America West initially operated
de Havilland Canada Dash 8 turboprop aircraft with its own flight crews; however, on November 30, 1992, America West signed a codeshare agreement with
Mesa Airlines to operate
America West Airlines' regional and commuter services as America West Express. In the mid-1990s, with the opening of the America West Airlines hub at
Port Columbus International Airport in
Columbus, Ohio, America West Airlines used Mesa Airlines first with CRJ200s for 8 years with a crew base of pilots and flight attendants and then both
Chautauqua Airlines to provide
Embraer ERJ 145 regional jet service to feed the hub. When the Columbus hub was shut down, the Chautauqua Airlines code share was discontinued, leaving Mesa as the sole operator of AW Express services. In 2003, America West greatly increased the size of its express operation by starting new routes operated by regional jets from its hub at
McCarran International Airport in
Las Vegas, Nevada. In 2007, America West Express was branded as
US Airways Express following the merger of America West with US Airways. ==Operators and fleet==
