If you’re flying in or out of Hartsfield–Jackson Atlanta International Airport (ATL), there’s a good chance you’re on Delta Air Lines. Atlanta is Delta’s main hub, and understanding which gates and terminals Delta uses at ATL can save you time, stress, and a lot of unnecessary walking.
This guide is written specifically for people living in Atlanta, visiting Atlanta, or connecting through ATL, and focuses on the Delta gates at Atlanta Airport and how to move around the airport smoothly.
At ATL, Delta dominates most of the concourses on the domestic side and also has major operations on the international side.
In general:
You’ll always want to check your boarding pass or airline app for your exact gate and concourse, because gate assignments can change.
ATL can be confusing if you’re not used to it. A key point:
Domestic Terminal – South
Domestic Terminal – North
International Terminal (Concourse F)
In order from west to east (closest to the Domestic Terminal on the left, International Terminal on the right):
All concourses are connected airside (after security). You can walk or use the Plane Train between any of them.
Here’s a simple view of Delta’s main concourses and typical use:
| Concourse | Main Use for Delta | Notes |
|---|---|---|
| T | Domestic departures/arrivals | Closest to Domestic Terminal; some Delta gates mixed with other carriers |
| A | Heavy Delta domestic traffic | Very busy; lots of business and frequent ATL flyers |
| B | Heavy Delta domestic traffic | One of the largest Delta concourses |
| C | Mostly Delta domestic, some other airlines | Moderate to heavy use |
| D | Mixed airlines, some Delta | Often used for domestic and some shorter routes |
| E | Delta international + some domestic | Close to F; can be used for domestic overflow |
| F | Delta and partners’ international flights | Attached to International Terminal |
Key takeaway:
If you’re flying Delta within the U.S., expect T through D, and possibly E.
If you’re flying Delta internationally, expect E or F.
Most Atlanta-based travelers use the Domestic Terminal – South when flying Delta within the U.S. or when starting an international trip from Atlanta.
At the South Terminal, you’ll find:
If you live in metro Atlanta and are driving yourself:
If you’re flying Delta to or from an international destination, you may check in at or arrive through the International Terminal, linked to Concourse F.
At the International Terminal, Delta provides:
Many international Delta flights use gates in Concourse F, but some depart or arrive from Concourse E. Your boarding pass will specify which.
If you’re coming from Atlanta or surrounding areas:
If you get dropped at the Domestic Terminal by mistake but your flight checks in at the International Terminal, you can still take the Plane Train after security to Concourse F—but if you need to check bags, it’s usually better to be dropped at the correct terminal from the beginning.
Once you’re past security, all Delta gates are connected on the secure side. You do not have to go through security again to change concourses.
The Plane Train is the quickest way to get between concourses:
If your Delta connection is tight (short layover), the Plane Train is almost always the best choice.
There are also underground pedestrian walkways connecting all concourses:
For example, walking from Concourse A to B is very doable; walking from T to F is long, but possible for those who prefer it and have time.
If you’re departing from Atlanta on Delta, your nearest security checkpoint will depend on your terminal:
Delta Domestic flights:

Local drivers sometimes underestimate how long it takes to:
Use the Delta app.
Many Atlanta-based travelers rely on it for:
Know that all concourses are connected airside.
If your gate changes from B to E at the last minute, you still don’t have to exit security—just hop on the Plane Train.
With this layout in mind, navigating Delta’s gates at Atlanta Airport becomes much more manageable, whether you’re a local ATL traveler, a visitor, or just connecting through one of the busiest hubs in the world.
