If you’ve ever searched for an Atlanta airport diagram, you’re usually trying to answer one of two questions:
Below is a clear, text-based “diagram” of ATL’s layout, concourses, roads, and train systems, written specifically for people who live in Atlanta, are visiting Atlanta, or are connecting through ATL.
ATL is essentially built in a straight line:
Two terminal ends
Seven concourses in between, labeled:
T – A – B – C – D – E – F
Two main underground systems connecting everything
Think of it as:
You clear security in either terminal and can reach all concourses without going back through security.
A lot of confusion comes from mixing up terminals and concourses.
Domestic Terminal (West side)
International Terminal (East side)
All concourses are after security and linked together.
| Area Type | Name / Letter | What It Is | Notes for Travelers in Atlanta |
|---|---|---|---|
| Terminal | Domestic | Check-in, baggage claim, security | West side of the airport; MARTA access |
| Concourse | T | Gates T1–T15 (approximate range) | Closest to Domestic security; easy for quick in-and-out |
| Concourse | A | Domestic gates | High Delta activity; one of the busiest concourses |
| Concourse | B | Domestic gates | Another major Delta concourse |
| Concourse | C | Domestic gates | Mix of airlines; lots of food options |
| Concourse | D | Domestic gates | Mix of airlines; often used for regional and mid-size jets |
| Concourse | E | Primarily international, some domestic | Used for many international flights, customs for some |
| Concourse | F | International + International Terminal | Houses customs/immigration and international check-in area |
| Terminal | International | Check-in, baggage claim, security | East side, connected directly to Concourse F |
You can enter ATL through either:
Main Security Checkpoint (Domestic Terminal)
International Terminal Security (Concourse F)
Once through either security, you can reach all concourses T–F via the Plane Train or pedestrian tunnel.
Runs in a straight line under the concourses with stops at:
Domestic Terminal – T – A – B – C – D – E – F – International Terminal
For most Atlanta travelers, the Plane Train is the fastest way to navigate the airport.
If you prefer walking:
You can mix and match:
If you’re Atlanta-based and driving someone to the airport, the road layout matters more than the concourse diagram.
If you’re picking someone up from an international flight:
While gate assignments can change, many Atlanta travelers see these general patterns:
Delta Air Lines
Other Domestic Airlines
International Carriers
Always confirm:
Example: Atlanta to New York
Check your airline:
Clear security at the Domestic Terminal.
Check your boarding pass for your concourse (T–D) and gate.
Choose:
Example: Arriving from Orlando, connecting to Chicago
💡 Tip for Atlanta-based frequent flyers:
If you know you usually depart from certain concourses (like A or B with Delta), you can plan buffer time but often don’t need to arrive extremely early once you’re familiar with the layout.
Example: Atlanta to Paris
You have two main options depending on your booking:
Check-in at International Terminal:
Check-in at Domestic, depart from E or F (common with certain carriers and setups):
Either way, your plane diagram is the same: all concourses are linked in order.
Example: Arriving from London into Atlanta
For pickups:
Understanding the airport diagram also helps you choose how to get between ATL and your destination in the city.
If you arrive at the International Terminal and want MARTA:
Mentally “drawing” Atlanta airport:
Imagine a horizontal line:
Under that line:
On the ends:
If you live in or near Atlanta, this is one of the most practical decisions:
Use the Domestic Terminal if:
Use the International Terminal if:
If in doubt, check:
By treating ATL like a straight line of concourses anchored by two terminals, most Atlanta travelers find it much easier to navigate—whether you’re a local catching a quick flight out of Concourse T or a visitor connecting between international and domestic gates.
