So, you’re looking for Terminal A at Phoenix Sky Harbor International Airport. I’m going to level with you right now: you aren’t going to find it. If you’re standing in the middle of the desert heat looking at a map and wondering why you can’t find a sign for Terminal A, don't worry. You haven't lost your mind.
Phoenix Sky Harbor (PHX) is one of the busiest airports in the United States, serving as a massive hub for American Airlines and Southwest. But it has a naming convention that feels like a riddle. Currently, Sky Harbor only operates two terminals: Terminal 3 and Terminal 4. There is no Terminal A. There isn't even a Terminal 1 or a Terminal 2 anymore.
It’s weird. I know.
Most people assume that "Terminal A" refers to the massive concourse inside Terminal 4, which is technically labeled as the "A" gates. If your boarding pass says "Gate A17" or something similar, you are heading to the John S. McCain III Terminal 4. This is the heart of the airport. It handles about 80% of the traffic at PHX. If you're flying American Airlines, you're almost certainly going here.
The Ghost of Terminals Past
To understand why everyone keeps searching for terminal a phoenix airport, you have to look at the history of how this place grew. Sky Harbor used to have a Terminal 1. It was built in 1952 and looked exactly like what you’d imagine a mid-century airport to look like—small, cramped, and eventually obsolete. It was demolished in the early 90s.
Then we had Terminal 2. It was famous for that massive, beautiful mural by Paul Coze called "The Phoenix." For decades, Terminal 2 was the spot for United, Alaska, and Delta. But as the city grew, Terminal 2 just couldn't keep up. It closed its doors for good in early 2020. The mural was saved, but the building is gone.
So why didn't they renumber them? Why jump straight to 3 and 4?
The airport authorities decided to keep the existing numbers to avoid mass confusion for pilots, ground crew, and frequent fliers who had spent twenty years memorizing the layout. If they had renamed Terminal 4 to "Terminal 1," every map, every digital system, and every road sign in the city of Phoenix would have had to change overnight. They chose the path of least resistance.

Navigating the "A" Concourse in Terminal 4
When people talk about Terminal A Phoenix Airport today, they are usually talking about the North Concourse of Terminal 4. This area is a beast.
Terminal 4 is divided into several "lettered" concourses. On the north side, you have the A gates (divided into A1-A14 and A15-A30). On the south side, you have the B gates. Then you have the C and D gates which primarily handle the massive Southwest Airlines operation.
If you are flying American Airlines, you are likely in the A or B gates.
If you are flying international (British Airways, Condor, Volaris), you are in the B gates.
If you are flying Southwest, you are in C or D.
The "A" gates at Terminal 4 underwent a massive expansion recently. The new eight-gate concourse (the "Eighth Concourse") opened to handle the overflow of American Airlines flights. It’s actually pretty nice. They added a bunch of local flavors like Pedal Haus Brewery and Berry Divine Acai Bowls. It doesn't feel like a standard, sterile airport hallway. It feels like Phoenix.
Terminal 3: The Other Player
Wait, if you aren't in Terminal 4, where are you? You're in Terminal 3, officially named the John S. McCain III Terminal (though both 3 and 4 technically share the name in various capacities, Terminal 3 is the "boutique" experience).
Terminal 3 is where you’ll find Delta, United, JetBlue, and Hawaiian. It was recently modernized in a multi-million dollar project. Honestly? It's the better terminal if you hate crowds. It’s airy, it has incredible views of the Camelback Mountain, and the security lines are generally faster than the chaotic mess you find at Terminal 4 during the Monday morning business rush.
Getting Between the Gates
If you accidentally go to the wrong place—which happens more than you’d think—you need the PHX Sky Train.

Do not try to walk. You can't. The terminals are separated by active taxiways and a lot of asphalt that gets hot enough to melt shoes in July. The Sky Train is free, it runs 24/7, and it connects the East Economy Parking, Terminal 4, Terminal 3, and the Rental Car Center. It’s incredibly efficient. If you’re looking for terminal a phoenix airport and you realize your flight is actually in Terminal 3, just hop on the train. It’s a 5-minute ride.
The Realities of Parking and Traffic
Phoenix is a "car city." Most people drive to the airport.
If you are heading to those "A Gates" in Terminal 4, you want to park in the Terminal 4 garage. But here is a pro-tip: that garage fills up fast. Like, really fast. Especially on Tuesday mornings when the consultants are all flying out.
The East Economy lot is usually the better bet. You park, you hop on the Sky Train, and it drops you right at the level 3 bridge of Terminal 4. From there, you just walk across the bridge, hit security, and you’re at the A gates in ten minutes.
If you’re being dropped off by an Uber or Lyft, tell them your airline. They know the drill. If you say "Terminal A," they might give you a confused look before correctly assuming you mean Terminal 4 American Airlines gates.
Where to Eat Near the A Gates
Since the "A" concourse is where most people end up when searching for Terminal A, let's talk food. Airport food usually sucks. It’s overpriced and soggy. But Sky Harbor actually tried to do something different by bringing in local restaurants instead of just Chili’s Express.
- Four Peaks Brewing: A local staple. The Kilt Lifter Scottish-style Ale is basically the unofficial beer of Arizona.
- Zinburger: If you want a decent burger that doesn't feel like a hockey puck.
- Blanco Tacos + Tequila: This is located in the pre-security area of Terminal 4, but it’s worth it if you have a long layover.
The new "A" gates extension (the 8th concourse) also brought in Bobby’s Burgers by Bobby Flay. It’s fine, but if you want the real Phoenix experience, stick to the local brands.

Common Misconceptions About PHX
I see this all the time on travel forums. Someone asks, "Which terminal is American Airlines in?" and someone else replies "Terminal A."
Strictly speaking, that’s wrong. It’s Terminal 4. If you put "Terminal A" into a GPS, it might get confused. Always look for the number.
Another big mistake is the Rental Car Center. It is not at the terminals. It is at a completely separate location miles away. You have to take the Sky Train to get there. If you return your car and think you can just walk to the A gates, you’re going to be walking through a very industrial, very hot part of town. Don’t do it.
What about International Arrivals?
If you are coming in from London or Frankfurt, you will land at the B gates in Terminal 4. You go through Customs and Border Protection there. Once you clear customs, you’re dumped out into the arrivals level of Terminal 4. If you have a connecting flight departing from an A gate, you have to go back through security.
This is the part that trips up international travelers. They see the "A" signs and think they can just walk there. You can, but only after you’ve re-cleared the TSA checkpoint.
Practical Steps for Your Trip
- Check your airline, not the letter. If you are flying Delta, Alaska, United, or Frontier, go to Terminal 3. If you are flying American, Southwest, or any international carrier, go to Terminal 4.
- Download the PHX Sky Harbor App. It sounds nerdy, but it has a real-time tracker for security wait times. If the North security checkpoint at Terminal 4 (near the A gates) is backed up, you can often go to the South checkpoint and walk across.
- Book parking in advance. The airport website offers discounts if you pre-book your parking spot in the Terminal 4 or East Economy garages. It can save you $5-$10 a day.
- Give yourself 2 hours. Even though PHX is efficient, the A gates are a long walk from the security terminal. If you’re at Gate A30, you’re looking at a 15-minute hike after you get through the metal detectors.
- Ignore the "Terminal A" search results. If a website tells you there is a standalone Terminal A, that website is outdated or using AI that hasn't checked a map since 1990.
Phoenix Sky Harbor is a great airport, honestly. It’s clean, the staff is generally friendlier than what you’ll find at LAX or O’Hare, and the Sky Train makes the layout manageable. Just remember: there is no Terminal A. There is only the "A" gates in Terminal 4. Follow the signs for 4, and you’ll be exactly where you need to be.
