Hartsfield-Jackson Atlanta is one of the easiest big airports to connect through, and the reason is the Plane Train — a free underground people mover that links every concourse airside, so you change concourses without ever leaving security. Trains come about every 2 minutes, and the full run from the domestic terminal to the international concourse takes under 10 minutes. Here’s how the Atlanta airport Plane Train works and how to use it for a smooth connection.
What is the Atlanta airport Plane Train?
The Plane Train is ATL’s automated underground shuttle running the length of the airport, connecting the Domestic Terminal (T) and concourses A, B, C, D, E and F. It’s free, runs 24/7 (in reduced mode 1–5 am), and arrives roughly every 2 minutes at peak. Crucially, it runs airside — inside the secure zone — so a connecting passenger stays past security the whole way. There’s also a parallel walkway above the tracks (the Transportation Mall) if you’d rather walk.
Plane Train stops and route
| Stop | What’s there |
|---|---|
| T — Domestic Terminal | Main security checkpoints, baggage claim, ground transport |
| Concourse A | Domestic gates (largely Delta) |
| Concourse B | Domestic gates |
| Concourse C | Domestic gates |
| Concourse D | Domestic gates |
| Concourse E | International and domestic gates |
| Concourse F | Maynard H. Jackson International Terminal — most international arrivals/departures |
The train runs in order T → A → B → C → D → E → F, so you simply board in the direction of your concourse and count the stops.
Do you have to re-clear security to change concourses?
No — and this is what makes Atlanta so connection-friendly. Because the Plane Train runs airside, moving between concourses on a domestic connection means you stay inside security the whole time. Just follow the signs down to the train, ride to your concourse and walk up to your gate. You only clear security once, when you first enter at the Domestic Terminal.
How long between concourses?
Each hop between adjacent stops is about 1–2 minutes, and the entire run from the Domestic Terminal to Concourse F is roughly 7–10 minutes including stops. Add a few minutes to reach the platform and walk to your gate. For a typical domestic-to-domestic connection at ATL, staying airside on the Plane Train, 45–60 minutes is usually comfortable — run tight connections through the layover calculator to be sure.
Arriving on an international flight (Concourse F or E)
International arrivals land at Concourse F (or E) and clear immigration and customs there. If you’re connecting to a domestic flight, you’ll re-check your bags and pass through security before rejoining the airside Plane Train to your departure concourse. That adds real time, so for an international-to-domestic connection at ATL budget at least 2 hours, more during busy arrival banks.
Frequently asked questions
How does the Atlanta airport Plane Train work?
It’s a free automated train running airside between the Domestic Terminal and concourses A to F, arriving about every 2 minutes. You stay inside security, so you can change concourses without re-screening.
Do you have to go through security again to change concourses at ATL?
No. The Plane Train runs airside, so on a domestic connection you stay inside the secure zone the whole way and only clear security once, at the Domestic Terminal.
How long does the Plane Train take from end to end?
About 7 to 10 minutes from the Domestic Terminal to Concourse F including all stops, with each hop between adjacent concourses taking 1 to 2 minutes.
How much time do I need to connect at Atlanta?
For a domestic-to-domestic connection on the airside Plane Train, 45 to 60 minutes is usually comfortable. For an international arrival connecting to a domestic flight, budget at least 2 hours to clear customs, re-check bags and pass security.
Can you walk between concourses at ATL instead of the train?
Yes. A walkway (the Transportation Mall) runs above the Plane Train tracks with moving walkways, so you can walk the whole length airside — but for far-apart concourses the train is much faster.
