Phoenix Sky Harbor International Airport has named American Airlines as the primary carrier for its future West Terminal. The new facility targets a late 2033 opening. It will be the airport’s first new terminal in nearly 40 years. American already handles more than 40% of Sky Harbor’s total passenger traffic.
Your next flight — and your drive to the airport — are both going to change
If you fly American out of Sky Harbor today, you board from Terminal 4. By late 2033, that changes. American will move into an entirely new West Terminal built to handle more international flying and larger aircraft. That means more nonstop options to destinations that aren’t on your current route map.
The move reshuffles things for everyone else too. When American leaves Terminal 4, it opens room for carriers like Southwest Airlines to expand their own gate count. More gates generally mean more competition and more flight choices — good news whether you fly American or not.
On the ground, expect years of visible construction near Sky Harbor Boulevard and the airport’s west side well before the terminal opens. The project is large enough that road and airfield work alone will be hard to miss on your drives to the airport.
Sky Harbor already moves about 140,000 passengers per day. It drives more than $44 billion in annual economic impact across the Valley. The West Terminal is the airport’s answer to growth that isn’t slowing down.
What was announced — and where the terminal fits on the map
Phoenix Sky Harbor announced American Airlines as the anchor carrier for the West Terminal. The announcement came alongside the unveiling of Destination PHX 2050. That is a long-range development program with a goal of 90 million annual passengers by 2050.
The West Terminal will sit on the airport’s west side, between Terminal 3 and Taxiway U. If you flew Sky Harbor before 2000, you know that footprint: it’s roughly where the former Terminals 1 and 2 once stood. Long-time Valley residents have a ready geographic anchor for exactly where this new building goes.

Who pays for it — and it is not your property taxes
This is the question most Valley residents don’t think to ask, and every other outlet skips the answer. Sky Harbor is funded entirely through airport revenue and passenger facility charges, plus bonds backed by those same revenue streams. Not one dollar comes from City of Phoenix property taxes or state tax dollars. If you never set foot on a plane, this project does not appear on your tax bill.
That said, the final cost and funding mix aren’t locked in yet. The current estimate is about $4.5 billion. The airport has stated that both the final price and the specific funding sources are still being worked out.
Construction already underway: Taxiway U and the Terminal 3 north concourse
You don’t have to wait until 2033 to see work happen. Two enabling projects are already underway on the airport’s west side right now.
First is Taxiway U, a new north-south taxiway built to increase airfield efficiency on the west side. Second is a new six-gate concourse on the north side of Terminal 3. Both projects lay the groundwork for the West Terminal. Valley residents and airport workers will see this construction activity throughout the buildout years.

American Airlines at Sky Harbor: the numbers behind the anchor choice
American is Phoenix’s largest airline. It carries more than 20 million customers through Sky Harbor every year and accounts for more than 40% of the airport’s total passenger traffic. The airline employs 8,000 team members across Arizona. Those numbers explain why the airport built the new terminal around American rather than the other way around.
November 4 Industry Day — and what it means if you run a small business
Phoenix Sky Harbor is holding a West Terminal Industry Day on November 4. The event will share the vision for the new terminal. It will also explain how the project will be delivered, including opportunities for small business participation in construction.
If you own or run a small business in the Valley and have any interest in airport contracting, this is the event to watch. It is one of the earliest public windows into how the project will be structured and who can compete for work.
November 4 Industry Day, then years of groundwork before 2033
The West Terminal Industry Day on November 4 is the next major milestone you can put on your calendar. After that, the airport will move through procurement, design finalization, and phased construction. Taxiway U and the Terminal 3 north concourse will be the visible near-term activity. The larger terminal plans will take shape behind them.
The opening target is late 2033. Between now and then, the airport’s west side will be the most active construction zone in the Valley. Plan extra time on your drives to the airport as that work ramps up.
