Atlanta Airport Delta Gates: How to Navigate Delta at Hartsfield-Jackson

If you’re flying Delta in or out of Atlanta, Georgia, you’re using Delta’s largest hub in the world: Hartsfield-Jackson Atlanta International Airport (ATL). Knowing which gates Delta uses, which concourses to expect, and how to move between them can save you a lot of stress and time—especially during busy travel days.

This guide walks you through Delta gates at Atlanta, how the airport is laid out, and what to expect whether you’re departing, arriving, or connecting through ATL.

Overview: Where Are Delta Gates in Atlanta?

Delta operates across multiple concourses at ATL. Most travelers will use:

• Domestic Terminal South (Terminal South) – Delta’s primary check-in and ticketing area
• Concourses T, A, B, C, D – Mainly domestic Delta gates
• Concourse E – Mix of Delta and other airlines, often international
• Concourse F – Maynard H. Jackson Jr. International Terminal, a major hub for Delta international flights

All concourses are connected by the Plane Train, an underground automated train that runs continuously.

Understanding the Atlanta Airport Layout for Delta Flyers

Terminals vs. Concourses

ATL can be confusing if it’s your first time. Here’s the key distinction:

• Terminals (North & South): Where you enter the airport from the street, check bags, and go through security.
  • Domestic Terminal – South: Delta’s main area for check-in and baggage drop.
• Concourses (T, A, B, C, D, E, F): Long hallways with gates where you actually board your plane.

You can check in at Domestic Terminal South and fly out of any domestic concourse, depending on your gate assignment.

Delta Check-In and Ticketing in Atlanta

Main Delta check-in:
Delta Air Lines – Domestic Terminal South
Hartsfield-Jackson Atlanta International Airport
6000 N Terminal Pkwy
Atlanta, GA 30320
Main airport info line (ATL): (800) 897‑1910 (general information)

Common setups you’ll find at Terminal South:

• Delta ticketing counters for standard check-in and bag drop
• Delta Sky Priority and First Class check-in areas
• Self-service kiosks for check-in and bag tags
• TSA security checkpoints leading toward the Concourse T entrance and the Plane Train

If you’re flying international with Delta, you may check in either:

Always confirm your departure terminal and check-in location on your booking or Delta’s app.

Which Concourses Does Delta Use in Atlanta?

Delta is heavily present across ATL. While gate assignments can change, Delta commonly uses:

Concourse T (Closest to Domestic Terminal)

• Located directly behind Domestic Terminal (you can walk here right after security).
• Often used for shorter domestic routes and some connection flights.
• Good option if you prefer to walk instead of taking the Plane Train for some flights.

Concourse A

• One of Delta’s primary domestic concourses.
• Many high-frequency routes (such as Atlanta–New York, Atlanta–Miami, etc.) depart here.
• Often busy during morning and evening peaks.

Concourse B

• Another major Delta-only concourse in ATL.
• Similar mix of domestic routes as Concourse A.
• Strong presence of Delta Sky Club locations.

Concourse C

• Mostly used by Delta and some partner regional flights.
• Common for short-haul domestic flights and regional connections.

Concourse D

• A mixed concourse, shared by Delta and other domestic carriers.
• Delta flights depart from many D gates, but not all gates here are Delta.

Concourse E

• Historically a primary international concourse, now used for both international and some domestic flights.
• Delta and other international airlines operate from here.
• Sometimes used for overflow or specific long-haul routes.

Concourse F (International Terminal)

• The Maynard H. Jackson Jr. International Terminal.
• Major Delta international departure and arrival area.
• Includes:
  • International check-in counters
  • Customs and immigration facilities
  • Several Delta-operated international gates

If you’re flying international on Delta (Europe, South America, some long-haul routes), there’s a good chance you’ll use Concourse F or E.

Quick Reference: Delta at ATL by Area

Getting Between Atlanta Delta Gates: The Plane Train

Most Delta passengers at ATL will ride the Plane Train at least once.

• The Plane Train is an underground tram that runs between:
  • Domestic Terminal (T)
  • Concourses A, B, C, D, E, and F
• Trains run frequently, usually every couple of minutes.
• Each concourse has clear signage and audio announcements.

Approximate travel pattern:

1. Enter security at Domestic Terminal South.
2. Follow signs to the Plane Train.
3. Ride to your assigned concourse (T, A, B, C, D, E, or F).
4. Walk down the concourse to your specific Delta gate (e.g., B12, A21).

You can also walk between concourses using the underground pedestrian tunnels, which feature art and displays, but that takes longer. The train is usually fastest, especially with tight connections.

Connecting Through Atlanta on Delta

If you’re connecting in Atlanta on Delta, your experience depends on whether you’re:

Domestic-to-Domestic Delta Connection

• Stay inside security; you do not need to exit to the terminal.
• Check your boarding pass or monitors for your next gate and concourse.
• Use the Plane Train to move between concourses.
• Typical connection times can be tight, so:
  • Head straight to your gate if your layover is under 45 minutes.
  • Use nearby restrooms and grab-and-go options near your departing gate.

Domestic-to-International Delta Connection

• You’ll arrive at a domestic concourse (often A, B, C, or D).
• Use the Plane Train to reach Concourse F or E, depending on your international gate.
• If your flight departs from Concourse F, you’ll be in the International Terminal with its own security side and amenities.

If you’re starting in Atlanta and flying international on Delta, check whether your itinerary suggests check-in at:

• Domestic Terminal South (common for connecting passengers), or
• International Terminal (Concourse F) if that’s more convenient for you

International-to-Domestic Delta Connection

If you arrive internationally into ATL on Delta:

1. You will arrive at Concourse F or E.
2. You must go through U.S. Customs and Border Protection and immigration.
3. Collect your checked baggage and re-check it after customs (if you have a connecting Delta flight).
4. Follow signs to domestic connections, then go through TSA security again.
5. Take the Plane Train to your new concourse (T, A, B, C, D, or sometimes E) for your domestic flight.

Give yourself a longer connection window for this, especially during peak international arrival times.

Where to Find Your Exact Delta Gate in Atlanta

Gate assignments in Atlanta change often, even on the day of travel. To find your exact Delta gate:

• Delta app or website
  • Enter your confirmation number or log in.
  • Check “Flight Status” for the most current gate and concourse.
• Airport departure boards
  • Located throughout Terminal South and all concourses.
  • Look up your flight number and destination.
• Announcements at the airport
  • Delta agents will announce gate changes and boarding times.

If you’re already at the airport and unsure, you can also ask a Delta gate agent or a customer service desk in any concourse.

Tips for Navigating Delta Gates at ATL Efficiently

A few practical ways to make Atlanta’s Delta operations easier to handle:

• Arrive early
  • For domestic Delta flights: arriving 2 hours before departure is often recommended.
  • For international Delta flights: 3 hours is safer, especially during busy seasons.
• Use mobile boarding passes
  • This can speed up security and reduce the need to stop at kiosks.
• Know your concourse before you eat or shop
  • ATL has good food and retail options, but if your gate is in Concourse B, it’s usually best to stay nearby rather than wandering to a distant concourse.
• Plan for walking time
  • Even once you’re on the right concourse, some gates are a long walk.
  • If mobility is a concern, you can request wheelchair assistance through Delta before your trip.
• Watch for last-minute gate changes
  • Especially in busy hubs like Atlanta, gates can shift up to departure time.
  • Check the monitors each time you pass one, and re-check the Delta app periodically.

Using the International Terminal (Concourse F) with Delta

If your Delta itinerary involves the International Terminal, here’s what to expect:

• Separate entrance by car:
  • Signage from I-75 and surrounding roads points to the International Terminal.
  • Different parking areas from the Domestic Terminal.
• Check-in and ticketing:
  • Delta has international check-in counters here, including lines for Sky Priority and premium cabins.
• Customs and arrivals:
  • Many Delta international flights arrive at F, where passengers clear customs and immigration.
• Connection to other concourses:
  • After clearing formalities, you can ride the Plane Train just like any other concourse.
  • You’ll remain on the secure side once you’ve re-cleared TSA (for connecting flights).

If you live in the Atlanta metro area and your flight starts in Concourse F, you may find it easier to go directly to the International Terminal instead of the Domestic side—especially if someone is dropping you off.
