Hartsfield-Jackson Atlanta International Airport doesn't actually use a "Terminal S"—a common point of confusion for travelers looking at outdated or confused routing guides. Instead, ATL operates two primary entry structures: the Domestic Terminal on the west side and the Maynard H. Jackson Jr. International Terminal on the east. Connecting these facilities are seven distinct concourses labeled T, A, B, C, D, E, and F. If you're hunting for a nonexistent terminal letter, you're likely trying to find the South Terminal checkpoints or parking decks within the domestic building.
Understanding this layout saves you from walking miles in the wrong direction. The airport handles nearly a hundred million passengers yearly, meaning a wrong turn at security can add thirty minutes to your transit time. This guide breaks down the actual layout, security locations, and transit methods so you can move through the property without stress.
Breaking Down the ATL Layout
The footprint splits cleanly down the middle. On the west sits the domestic complex, split into North and South sides. On the east sits the international structure. Running beneath all of them is the transportation spine containing the underground train and pedestrian walkways.
Domestic Terminal Sections
The domestic building is a single massive structure divided into two distinct halves for ticketing and baggage claim:
- North Terminal: Primarily handles airlines other than Delta, though check your boarding pass carefully since gate assignments shift.
- South Terminal: Dedicated heavily to Delta Air Lines, featuring high-volume bag drop and check-in counters.
- Parking Decks: North and sandwich the central atrium, offering direct hourly and daily access.
The Seven Concourses
From west to east, planes park at seven sequential concourses. You can reach any of them using either the underground Plane Train or the pedestrian tunnel featuring the moving walkways and art displays.
- Concourse T: Closest to the domestic main terminal, featuring gates T1 through T21.
- Concourse A through D: Heavy domestic traffic hubs, dominated by Delta operations alongside select carriers.
- Concourse E and F: International flight handlers. Concourse F connects directly to the Maynard H. Jackson Jr. International Terminal.
Navigating Between Concourses
You have two main choices when moving between gates: riding or walking.
The underground Plane Train arrives every couple of minutes at every concourse. It takes less than five minutes to travel from Concourse T all the way to Concourse F. Listen to the automated announcements so you don't miss your stop.
If you prefer walking, the pedestrian tunnel sits right beneath the train tracks. It features the famous multi-sensory forest light display and moving sidewalks. Walking the entire length from the domestic terminal to Concourse F takes about fifteen to twenty minutes if you maintain a steady pace.
Security Checkpoints and Access Points
Where you clear security depends entirely on your airline and ticket type.
The domestic side features North, South, and Main checkpoints. The South checkpoint handles heavy volume and features dedicated PreCheck lanes. The international terminal operates independent security checkpoints on its upper level.
- TSA PreCheck: Available at both domestic and international entrances. Look for designated queue markers before joining the line.
- CLEAR Lanes: Positioned at primary domestic and international checkpoints for biometric fast-tracking.
If you arrive via the domestic side for an international flight on an airline like Air France or British Airways, you can check in at the domestic counters, but many international carriers prefer you use the international terminal facilities on the east side. Check your airline's app before heading to the curb.
Common Mistakes to Avoid
Travelers frequently trip up on a few logistical hurdles at Hartsfield-Jackson. Keep these points in mind to protect your schedule:
- Going to the wrong terminal entrance: If you are flying domestically, don't go to the international terminal on I-75. It forces a long shuttle ride back across the airfield.
- Ignoring the Plane Train loop: Once you clear security, you can visit any concourse freely. Don't exit security just to change concourses.
- Underestimating check-in cutoffs: International bag drop closes strictly 60 minutes before departure for most carriers. Arrive at least three hours before international flights.

Frequently Asked Questions
Is there really a Terminal S at Atlanta Airport?
No. "Terminal S" is a misnomer. Travelers often confuse the South Terminal domestic check-in area with a separate lettered terminal.
How do I get between the domestic and international terminals?
You can ride the complimentary terminal shuttle bus from outside the arrivals curb, or clear security and take the Plane Train underground.
Can I walk between all concourses?
Yes. A well-lit pedestrian tunnel with moving walkways connects every single concourse from T to F, running parallel to the underground train.
Where is baggage claim for international arrivals?
Passengers arriving on international flights clear customs and collect checked bags directly inside the Maynard H. Jackson Jr. International Terminal on the east side.
