Hartsfield–Jackson Atlanta International Airport (ATL) is huge, busy, and very organized—once you understand its layout. If you live in Atlanta, fly often through ATL, or you’re visiting the city, knowing how the Atlanta airport terminal map and concourse layout works will save you time and stress.
This guide walks you through the overall layout, terminals, concourses, security checkpoints, Plane Train, and baggage claim, all with a practical, Atlanta-focused perspective.
Instead of multiple disconnected terminals, ATL is laid out in a straight line:
Think of it like this:
You can reach any airline gate from either terminal once you’re past security, as long as you have time to ride the train or walk.
The Domestic Terminal sits at the western end of the airport and is split into two main sides:
You can walk between North and South inside the Domestic Terminal. If you’re getting dropped off and not sure which side to use:
The International Terminal sits on the east side of the airport, separate from the Domestic Terminal road access.
Key features:
Once you go through security at the International Terminal, you can still reach all other concourses (T–E) using the Plane Train or the pedestrian tunnel.
After security, ATL’s gates are in seven concourses, arranged in this order from west to east:
You move between them via the Plane Train or by walking underground.
| Concourse | Typical Use | Closest Terminal |
|---|---|---|
| T | Domestic flights, mix of airlines | Domestic Terminal |
| A | Heavy Delta presence, domestic | Between Domestic & middle |
| B | Mainly Delta domestic | Middle of the airport |
| C | Multiple domestic carriers | Middle–east side |
| D | Domestic and some international flights | East of C |
| E | International flights, some domestic | Between Domestic & Intl |
| F | International flights, main intl terminal | International Terminal |
Note: Airlines can shift gates, but Delta has a strong presence in T, A, B, C, D, E, and F.
You cannot see the actual terminal map clearly until you pass TSA security, so it helps to choose the right checkpoint from the start.
For most Atlanta-based travelers flying domestic:
Once you pass through this checkpoint, you can still use the Plane Train to visit any concourse.
The Plane Train is the airport’s underground people mover connecting:
Key points:
Times can vary slightly, but a general pattern is:
If you’re connecting from, say, Concourse B to Concourse E, you’ll likely ride through C and D on the way. Plan a few extra minutes per concourse crossed during tight connections.
If you prefer to walk or the Plane Train is crowded, there’s a pedestrian tunnel parallel to the train route.
Walking can be a good choice if:
However, if you’re going from T to F or similar long distances on a tight schedule, the Plane Train is faster.
Your baggage claim location depends on:
If you live in or are staying in Atlanta and flew in on a domestic U.S. flight, you will almost always claim bags here.
Some international arrivals use Concourse E, but passengers may still be routed toward the International Terminal for customs. Follow the posted arrival signs and airline instructions.
Once you’re out of baggage claim, the ground transportation layout differs between the Domestic and International sides.
You’ll find, in or around the Domestic side:
The MARTA Airport Station is directly attached to the Domestic Terminal, making it an easy option for:
The International side has:
If you arrive at the International Terminal but want to use MARTA or meet someone at the Domestic side, free airport shuttles connect the two.
As an Atlanta-area driver, it helps to understand parking by which terminal you’ll use.
You’ll see options like:
Best for:
Closer to the International Terminal:
If you park at the International side but depart from the Domestic side (or vice versa), allow extra time for:
Here are some Atlanta-specific tips for handling the airport layout:
Leaving from I-75/I-285 East or Northeast Atlanta?
Sometimes the International Terminal access road is more direct for international flights than driving around to the Domestic side.
Picking someone up?
Connecting through Atlanta often?
Traveling with kids or mobility concerns?
While you can’t see every detail of the concourses until you’re inside, ATL posts clear maps and signage throughout the airport. Once you’re at the airport:
Since the layout is linear, once you know:
you just follow signs and either:
Understanding the Atlanta airport terminal map and layout comes down to remembering a few core ideas: two main terminal sides (Domestic and International), seven concourses in a line, and the Plane Train tying everything together underground. Once you have that mental map, getting around ATL becomes much more predictable—whether you’re an Atlanta local heading out for a quick trip or a visitor connecting through the city.
