Future West Terminal to Enhance Convenience, Connectivity for Travelers
October 14, 2026
The planned future West Terminal is envisioned to be built on the west side of Phoenix Sky Harbor and will be the airport’s first new terminal since Terminal 4 opened in 1990. It will serve as the main front door for growing international travel and will be designed to accommodate additional wide-body aircraft.
American Airlines, which serves more than 40% of all passengers at Phoenix Sky Harbor, will be the primary carrier for the new terminal. The project also provides opportunities for all airlines at PHX to continue expanding and serving travelers across Arizona.
The number of gates and final design features are still being developed. Construction could potentially begin in late 2029 with an opening in late 2033. The project will be funded with passenger facility charges, bonds, and airport funding. No local tax dollars will be used.
Phoenix Sky Harbor is also investing in improvements to Terminal 4, which currently handles the majority of airport traffic. Upgrades include modernization of the baggage system, concessions, building infrastructure and more.
This project along with other capital improvements outlined in Destination PHX 2050, the airport’s long-term development program, demonstrates Phoenix Sky Harbor’s commitment to improving the passenger experience and preparing for long-term growth.
