Airlines with a major presence at Sky Harbor include Ameriflight, Great Lakes Airlines, US Airways and Southwest Airlines. Some Phoenix flights land at Phoenix-Mesa Gateway Airport (AZA), which is located in the nearby city of Mesa. Formerly an air force base, Phoenix-Mesa now services the Phoenix metropolitan area. Only two airlines fly to Phoenix-Mesa: Allegiant Air and Spirit Airlines.
Allegiant Airlines announced Tuesday they are making plans to leave Mesa Gateway Airport, where they have operated since 2007, in favor of Sky Harbor International Airport in Phoenix. This comes after the airport signed a deal with Maine-based Elite Airways to fly into Salt Lake City and San Diego.
