America West Airlines was a U.S. airline headquartered in Tempe, Arizona. Its main hub was at Phoenix Sky Harbor International Airport. The airline became part of the US Airways Group after a merger in 2005.
Prior to the merger, America West operated two hubs: its base location at Sky Harbor Airport in Phoenix, Arizona and a secondary hub (now defunct) at McCarran International Airport in Las Vegas, Nevada. America West was the second largest low-cost carrier in the US and served approximately 100 destinations in the US, Canada, and Mexico. Service to Europe was provided through codeshare partners.
As of March 2005, the airline operated a fleet of 140 aircraft, with a single maintenance base at Sky Harbor Airport in Phoenix.
