In order to accommodate the increase in passenger numbers the airport authority has initiated the Phoenix-Mesa Gateway Airport Northeast Area Development Plan, entitled 'Gateway 2030', which was prepared over a 20-month period.

The second phase of expansion, which is expected to cost $145m, will expand the earlier development phase and allow the airport to handle 4.4 million passengers per year.
During the second phase, the airport will add four additional gates, expand parking spaces to accommodate 10,500 vehicles and carry out a 1,000ft runway 12L/30R extension.
Gateway Airport's third phase expansion, to be carried out with an investment of $963m, will increase the capacity of the terminal to 10 million passengers with expanded parking garages and 30 total aircraft gates.
Phase four improvements comprise a total of 60 aircraft gates, 21,000 vehicle parking spaces, and twin landside terminal arrival and departure curbs on two levels, which would allow the airport to serve 20 million passengers per year.
