Honestly, if you've ever stepped foot in Hartsfield-Jackson Atlanta International Airport (ATL), you know the feeling of absolute scale. It’s huge. It’s overwhelming. You look at a map and it looks like a giant, metal centipede stretched across the Georgia landscape. One of the biggest points of confusion for travelers—whether it's your first time or you're a seasoned Delta loyalist—is a deceptively simple question: how many terminals does Atlanta airport have?
Most people will tell you there are three. Or maybe seven? Some might even say one.
The truth is actually pretty straightforward, but the way the airport is laid out makes it feel way more complicated than it needs to be. Technically, Hartsfield-Jackson has two main terminals: the Domestic Terminal and the Maynard H. Jackson Jr. International Terminal.
That’s it. Just two.
But if you’ve ever looked at your boarding pass and seen "Terminal S" or "Terminal N," or wandered through the alphabet soup of Concourses A through F, you know the "two terminal" answer doesn't tell the whole story. Let’s break down what’s actually happening on the ground so you don't end up sprinting through the world's busiest airport for no reason.
The Two-Terminal Setup: A Tale of Two Sides
Basically, the Atlanta airport is designed like a "fishbone." The two terminals sit at opposite ends of the spine, and the concourses—where the actual planes are—sit in the middle like ribs.

The Domestic Terminal (The West Side)
This is where most of the action happens. Located on the west side of the airport, the Domestic Terminal is divided into two parts: Terminal North and Terminal South.
This is where the confusion starts. People see "North" and "South" and assume they are separate buildings. They aren't. They are two sides of the same massive hall, separated by a giant atrium filled with restaurants and shops.
- Terminal South: This is basically Delta territory. If you’re flying Delta domestic, this is where you check your bags.
- Terminal North: This is for literally everyone else—Southwest, American, United, Spirit, Frontier.
The International Terminal (The East Side)
On the far east side of the complex sits the Maynard H. Jackson Jr. International Terminal. It’s newer, shinier, and completely separate from the domestic side in terms of road access. If you are flying to London, Paris, or Tokyo, this is where you need to be.
Crucially, the International Terminal has its own entrance off I-75. If you accidentally drive to the Domestic Terminal (off I-85) for an international flight, you’re in for a 15-minute shuttle ride around the perimeter of the airfield. Not fun.
Concourses vs. Terminals: Don't Let the Letters Fool You
When people ask "how many terminals does Atlanta airport have," they are usually thinking of the concourses. In Atlanta, a "terminal" is where you check in and grab your bags. A "concourse" is where the gates are.

ATL has seven concourses: T, A, B, C, D, E, and F.
- Concourse T: This is the only one actually attached to the Domestic Terminal.
- Concourses A, B, C, and D: These are the "domestic" ribs.
- Concourse E: The original international concourse. It still handles international flights but is located in the middle of the "spine."
- Concourse F: This is the international concourse directly attached to the International Terminal.
If your gate is B19, you aren't in "Terminal B." You are in Concourse B. It sounds like semantics, but knowing the difference helps you understand the signage when you're rushing to a connection.
The Secret Weapon: The Plane Train
How do you get between these two terminals and seven concourses? You hop on the Plane Train.
This automated people mover is the heartbeat of the airport. It runs in a tunnel underneath the concourses. It’s fast, it’s free, and it comes every two minutes. If you’re at the Domestic Terminal and your flight leaves from Concourse C, you go downstairs, hop the train for two stops, and you’re there.
One thing I love? The walk between concourses. If you have time, there’s a pedestrian walkway parallel to the train tracks. Between Concourses A and B, there’s an "underground rainforest" art installation with bird sounds and specialized lighting. It’s a great way to decompress between flights.

What Most Travelers Get Wrong
Here is the "pro tip" that saves a lot of headaches. The "Terminal" on your boarding pass usually only matters for check-in and baggage claim.
If you are just connecting through Atlanta—say, flying from Birmingham to New York with a stop in ATL—you don't need to worry about the Domestic or International terminals at all. You just land at one gate, check the monitors for your next gate (e.g., "Gate B24"), and take the Plane Train to that letter. You never have to leave the secure area.
However, if you are starting your journey in Atlanta, you must go to the correct terminal to check your bags. Delta = South. Everything else domestic = North. International = International.
Actionable Tips for Your Next ATL Visit
Navigating this beast of an airport doesn't have to be a nightmare. Here’s how to handle it like a local:
- Check the Entrance: If you're taking an Uber or being dropped off, double-check if your flight is international. Driving to the wrong terminal can cost you 20 minutes you might not have.
- Use the SkyTrain for Parking: Don't confuse the "Plane Train" (inside security) with the "SkyTrain" (outside security). The SkyTrain takes you from the Domestic Terminal to the Rental Car Center and the GICC.
- The "T" Gate Shortcut: If you aren't checking bags and your gate is in Concourse T, use the North or South security checkpoints. You’ll walk right out onto the concourse without needing the train.
- International Bag Recheck: If you arrive on an international flight and Atlanta is your final destination, you pick up your bags at the International Terminal. If you’re connecting to a domestic flight, you’ll clear customs, recheck your bags right there, and then take the Plane Train to your domestic concourse.
Atlanta is efficient, but it’s unforgiving to the unprepared. Now that you know there are really only two terminals—and how they connect to the seven concourses—you’re already ahead of 90% of the people wandering around looking lost.
To make your trip even smoother, download the ATL airport app or the Delta FlyReady app. They provide real-time updates on security wait times at each terminal entrance, which can vary wildly between the North, South, and International checkpoints. If the North checkpoint is backed up, sometimes the International side is a ghost town. Just remember: once you're through security, the whole airport is your oyster.
Next Steps:
- Check your airline’s terminal assignment before leaving for the airport.
- If you have a layover longer than two hours, plan to walk between at least two concourses to see the art installations.
- Verify your gate number on the overhead monitors as soon as you land; gate changes are frequent in a hub this size.
