Phoenix–Mesa Gateway Airport continues to be owned and operated by the Phoenix Mesa Gateway Airport Authority. A six-member airport Board of Directors is composed of elected officials from neighboring cities and a tribal government. Authority communities are:  The airport covers and has three paved runways:  In the year ending December 31, 2018 the airport had 288,921 aircraft operations, average 791 per day: 78% general aviation, 16% air taxi, 4% airline and 2% military. In 2018, 126 aircraft were based at this airport: 87 single-engine, 20 multi-engine and 18 jet and 1 helicopter. One of the biggest issues at IWA is the increase in passengers since Allegiant Air started operations. IWA did not anticipate this growth within the first year. Due to the increase from 14,588 enplanements in 2007 to 159,481 in 2008, facilities were becoming crowded. To alleviate this problem, extensive renovations and expansions have been completed, adding nearly of new space within the terminal. This added eight gates since IWA was established in 1994. The Airport broke ground on a final expansion plan in early 2013, to increase gates to ten. However, IWA is running out of real estate on the west side of the airfield, which will bring a halt to expansions until the east terminal facilities are complete. In response to the expansion issues, PMGAA has begun planning for a new east terminal. The plan titled, Gateway 2030, was developed in June 2012. The Gateway 2030 plan outlines the process, major findings, and recommendations associated with the cost feasible phasing approach to the development of approximately of airport property and the supporting City infrastructure critical to ensure its success" (IWA, 2012b). The plan will be implemented in 4 phases. With the completion of phase one, IWA will be able to accommodate 1.5 million enplanements (3 million passengers). Much of phase one will address much needed access and infrastructure for access to the new terminal. The addition will include access roads, parking, taxiways, aprons capable of Group III and IV aircraft, and the new pier concept terminal. The new terminal will have 14 gates, constructed in such a way to make room for 12 Group III aircraft and two Group IV aircraft. Phase two has yet to be planned in detail, but will add another pier terminal to the main concourse, adding up to six gates, parking for 10,500 vehicles, and a extension of RW 12L/30R. Phase two will create the ability for IWA to handle 2.2 million enplanements.
