Williams Gateway Airport (IWA): Mesa's Military-Heritage Commercial Aviation Hub
Williams Gateway Airport (IATA: IWA) is the historical identifier for what is now officially known as Phoenix-Mesa Gateway Airport (AZA), built on the site of Williams Air Force Base in Mesa, Arizona. The "IWA" IATA code and "Williams Gateway" name honor the Air Force base history while the facility has transitioned into a major commercial and general aviation airport serving the Phoenix East Valley. Williams AFB trained over 25,000 Air Force pilots during its operational history from 1941 to 1993, including many astronauts and foreign military pilots through international training programs. The airport's conversion from military use to civilian commercial service represents one of the most successful military base reuse projects in American aviation history.
The Williams Gateway / Phoenix-Mesa Gateway Airport campus encompasses approximately 3,700 acres with multiple long runways (10,000 feet) that can handle wide-body commercial aircraft and support the aircraft maintenance and storage operations that have established the airport as a major MRO (Maintenance, Repair, and Overhaul) center. The FAA Western-Pacific Region oversees the airport's airspace within the Phoenix TRACON, and the Arizona Department of Transportation Aeronautics Group works with the Mesa Airport Authority on the facility's ongoing commercial and general aviation development. Airlines using the IWA/AZA facility serve the East Valley's 1.5 million-plus residents with ultra-low-cost carrier service to leisure destinations across the United States.
What is the history of Williams Air Force Base at this airport?
Williams AFB operated from 1941 to 1993 as one of the US Air Force's premier undergraduate pilot training bases, graduating over 25,000 military aviators during its 52-year history. The base flew training aircraft including the T-37 and T-38 Talon jets, and its sunny Arizona climate enabled year-round flying operations. The base was recommended for closure in the 1991 BRAC process and closed in 1993.
Why are there two IATA codes for this airport (IWA and AZA)?
IWA was the original IATA code assigned to Williams Gateway Airport, while AZA is the code used for Phoenix-Mesa Gateway Airport following the official renaming. Both codes may appear in aviation databases and booking systems depending on when the data was last updated. Travelers should confirm which code is active when booking flights.
What MRO operations are based at Williams Gateway/Phoenix-Mesa Gateway?
The large hangar and ramp infrastructure from Williams AFB has attracted major aircraft maintenance operations to the campus. Airlines including Allegiant and others use the facility for aircraft storage and maintenance, and specialty MRO companies operate on the airport campus, making it one of Arizona's most significant aircraft maintenance centers.

Williams Gateway/Phoenix-Mesa Gateway: Military Legacy, Commercial Future
The transformation of Williams Air Force Base into a thriving commercial and general aviation airport is a testament to Arizona's aviation heritage and the effective conversion of military infrastructure to civilian benefit. The Williams AFB Heritage Museum preserves the history of the base's pilot training legacy, and the airport's educational partnerships with Embry-Riddle Aeronautical University and Chandler-Gilbert Community College create a pipeline of aviation professionals who carry on the tradition of excellence in aviation that Williams AFB exemplified. The East Valley's aviation culture—concentrated around Mesa, Chandler, Gilbert, and Queen Creek—owes much to the Williams heritage.
Phoenix-Mesa Gateway Airport (IWA/AZA) serves the 1.5 million-plus residents of the Phoenix East Valley with commercial airline access through Allegiant Air and other carriers, providing alternatives to Sky Harbor for leisure travel. General aviation pilots find the facility's long runways, extensive facilities, and lower congestion than PHX or SDL attractive for both based aircraft and transient operations. The Arizona Department of Transportation Aeronautics Group considers AZA/IWA an important component of the Phoenix metro aviation system, and the FAA Western-Pacific Region coordinates its airspace within the Phoenix TRACON to ensure safe, efficient operations in one of the busiest general aviation metropolitan areas in the country.
