Hartsfield‑Jackson Atlanta International Airport (ATL) is huge, busy, and central to life in and around Atlanta. Whether you live in the metro area, fly out a few times a year, or are visiting the city for work or fun, understanding Atlanta airport terminals will save you time, stress, and a lot of walking.
This guide breaks down how the terminals are set up, where airlines operate, how to move between concourses, and what to expect if you’re arriving, departing, or just connecting through ATL.
ATL is organized around one main terminal building plus a series of concourses that spread out like a spine.
Even though people often say “Atlanta airport terminals,” what you really use day‑to‑day are:
Once you’re past security, all concourses are connected airside, so you can move between them without going through security again.
If you’re flying within the U.S. from Atlanta, you’ll start on the Domestic side.
The North Terminal handles several major domestic airlines. This is where you’ll typically check in and drop bags if you’re flying with:
You’ll find:
The South Terminal is essentially Delta’s terminal. If you live in Atlanta, chances are you’ve used this side frequently.
You’ll find:
Because ATL is Delta’s main hub, the South Terminal and Concourses T, A, B, C, and D are heavily used by Delta and Delta Connection flights.
If you’re flying to or from another country, you’ll likely interact with the Maynard H. Jackson Jr. International Terminal, which is linked to Concourse F and close to Concourse E.
Many international airlines serving Atlanta use this terminal for:
International flights may use E or F for arrivals and departures. Your actual gate could be in either, even if you checked in at the International Terminal.
| Area | Main Use | Who Typically Uses It |
|---|---|---|
| Domestic Terminal – North | U.S. domestic check‑in, baggage, arrivals | United, Spirit, Frontier, Alaska, JetBlue, etc. |
| Domestic Terminal – South | Delta check‑in, baggage, arrivals | Delta & Delta Connection |
| Concourse T | Domestic gates | Delta + other domestic carriers |
| Concourse A | Mostly domestic | Heavy Delta presence |
| Concourse B | Mostly domestic | Nearly all Delta |
| Concourse C | Mostly domestic | Mixed airlines, many Delta flights |
| Concourse D | Domestic/regional | Mixed carriers |
| Concourse E | International + some domestic | Delta + international partners |
| Concourse F (Intl. Terminal) | Main international gates & arrivals | Delta + many foreign carriers |
| International Terminal (F side) | Intl. check‑in, customs, arrivals | All international travelers using F |
Always confirm your airline, terminal, and gate before you leave for the airport, because gate and concourse assignments can change.
Once you clear security on either the Domestic side or the International side, the airport is designed so you can move easily between concourses.
The Plane Train is the fastest way to move between:
Trains run continuously, and stops are clearly announced. From one end to the other (T to F) usually takes just a few minutes.
There are also underground pedestrian walkways connecting the concourses. These are:
You do not need to exit security to move between concourses T–F.
Where you arrive depends on whether your flight is domestic or international.
If Atlanta is your final stop in the U.S.:
If you’re connecting onward within the U.S., you’ll go back into the secure area after re‑checking bags and then use the Plane Train to your domestic concourse.
If you’re leaving Atlanta, your experience will differ slightly based on whether you’re flying domestic or international.
If your flight departs from Concourse F and your airline uses the International Terminal, you may:
If you’re leaving from Concourse E or another concourse on a connecting itinerary, you might check in on the domestic side and then connect airside.
When in doubt, confirm:
Atlanta residents and visitors should pay attention to which side of the airport they’re using, especially when meeting someone or scheduling a pickup.
This is the side most local travelers use for everyday domestic flights.
If you’re picking up someone flying in from overseas, confirm whether they are arriving via Concourse E or F and where their airline directs them to meet rides.
Security screening is located at:
Once you’ve passed through any of these checkpoints, you can reach all concourses (T–F) without exiting security.
Atlanta‑area residents often choose checkpoints based on:
Atlanta is one of the busiest connection hubs in the world. If you’re just connecting through:
For international‑to‑domestic connections, you’ll need to:
Plan extra time for this if you’re connecting to a domestic flight back to Atlanta suburbs or another U.S. city.
You’ll find restaurants, shops, and services throughout the airport, but some areas are more fully built out than others.
For Atlanta‑area travelers, it can be worth arriving a little early if you want to enjoy a meal at the airport, especially in Concourses A, B, or F, where the variety is often larger.
Here are some locally useful, time‑saving points for dealing with ATL’s terminals and concourses:
Know your side before you go.
Domestic vs. International, and then North vs. South for domestic check‑in.
Plan extra time for parking and shuttles.
With ATL’s size, simply getting from parking into your terminal can take longer than you expect, especially at peak times.
If you’re meeting someone, clarify the exact pickup area.
“International Terminal arrivals” vs. “Domestic Terminal South curb” makes a big difference in traffic and timing.
Use the Plane Train if you’re in a hurry.
Walking is possible, but concourses are far apart; the train saves many minutes.
If you live in metro Atlanta, consider how you’re getting to the airport.
Understanding this structure makes it much easier to plan rides, meet visitors, and move confidently through Atlanta’s airport—whether you call Atlanta home or you’re just passing through.
