The Desert Sun Airlines division was created in 1995 to inaugurate Mesa's first jet service utilizing Fokker 70 aircraft. It operated as America West Express from a Phoenix hub. The first two cities to receive jet service were Spokane and Des Moines. In 1996, the division was merged into Mesa's America West Express operation, and the Fokker 70 aircraft were replaced by Bombardier CRJ aircraft as they were introduced. There was also a previous Desert Sun Airlines not affiliated with Mesa that operated scheduled passenger commuter service in southern California during the mid-1980s with Beechcraft 99 turboprops and Piper Chieftain prop aircraft.
