The airport, owned and operated by the Phoenix Mesa Gateway Airport Authority, is a reliever airport for Phoenix Sky Harbor International Airport. It is a base for Allegiant Air. The airport authority is governed by a six-member board: the mayors of the towns of Gilbert and Queen Creek, the mayors of the cities of Mesa, Phoenix and Apache Junction, as well as the tribal governor of the Gila River Indian Community. The FAA’s National Plan of Integrated Airport Systems for 2007 2011 called Phoenix Mesa Gateway a reliever airport, which is a general aviation airport used to relieve congestion at a large airline airport. Allegiant Air began scheduled service from Mesa in October 2007. Phoenix Mesa Gateway Airport records say the airport had 1,338,216 passenger boardings in calendar year 2017. Most U. S. airports use the same three-letter location identifier for the FAA and IATA, but Phoenix Mesa Gateway Airport has different codes for each. The aviation community generally uses the FAA code of IWA, while commercial passenger flight organizations use the IATA code of AZA.
