Phoenix Sky Harbor Unveils West Terminal and American Airlines Hub

On September 21, 2026, Phoenix Sky Harbor International Airport officially announced American Airlines as the primary carrier for its forthcoming West Terminal. This development is a cornerstone of the airport's newly unveiled 'Destination PHX 2050' master plan, an ambitious infrastructure program aimed at preparing the airport to handle an anticipated 90 million annual passengers by 2050. The West Terminal project marks the first major terminal construction at the airport since Terminal 4 opened in 1990.

In addition to the new terminal, the airport is investing hundreds of millions of dollars into modernizing the existing 36-year-old Terminal 4, which currently processes over 75% of the airport's total passenger volume. Planned upgrades focus on critical passenger-facing infrastructure, including baggage handling systems, moving walkways, and the concessions program. This strategic partnership with American Airlines is intended to solidify Phoenix's role as a major global gateway and facilitate increased tourism and business connectivity for the region.

Passengers traveling through Phoenix Sky Harbor, particularly those flying on American Airlines, will be affected by these long-term infrastructure improvements. While the current impact is primarily related to ongoing facility upgrades in Terminal 4, future travelers should anticipate construction activity as the West Terminal project progresses.

Makutet expects that by anchoring the new West Terminal to a major legacy carrier like American Airlines, Phoenix Sky Harbor is positioning itself to capture a larger share of transcontinental and international traffic. We forecast that as 'Destination PHX 2050' matures, the airport will likely see an increase in direct long-haul routes, leveraging the modernized facility to compete more aggressively with other Western US hubs.
