Which Terminal Does Delta Use at Atlanta Airport? A Clear Guide for Hartsfield-Jackson

If you’re flying Delta in or out of Atlanta, Georgia, you’re using Delta’s main hub at Hartsfield-Jackson Atlanta International Airport (ATL). But ATL is big and can be confusing, especially when you’re not sure which terminal or concourse you need.

Here’s the short answer:

• Domestic Delta flights: Usually through the Domestic Terminal – South and Concourses T, A, B, C, and D
• Most international Delta departures/arrivals: Through the Maynard H. Jackson Jr. International Terminal and Concourses E and F
• You never have to leave the secure area to move between concourses once you’re past security.

Below is a detailed, Atlanta-focused guide to help you get exactly where you need to go.

Delta at ATL: Terminals vs. Concourses (What’s the Difference?)

At Hartsfield-Jackson, it helps to separate two ideas:

• Terminals = where you enter the airport from the street (ticketing, check-in, baggage claim)
• Concourses = where your gates are located once you’re past security

ATL has:

• Domestic Terminal (West side)
  • North (mostly for other airlines)
  • South (Delta’s main check-in area)
• International Terminal (East side) – Maynard H. Jackson Jr. International Terminal

Behind security, there are seven concourses in a straight line:

T – A – B – C – D – E – F

All concourses are connected by:

• The Plane Train (underground people mover)
• Walkable corridors (with moving walkways)

Once you go through security at either terminal, you can reach any concourse and any Delta gate without re-screening.

Which Terminal Do I Use for Delta in Atlanta?

For Most Domestic Delta Flights

If you’re flying within the U.S. on Delta (for example, to New York, Orlando, Dallas, etc.):

• You will typically use the
  ➡ Domestic Terminal – South (Delta)
• After security, your gate will be in one of these concourses:
  • Concourse T (closest to the Domestic Terminal)
  • Concourse A
  • Concourse B
  • Concourse C
  • Concourse D

You can check your exact departure concourse and gate on your:

• Delta app
• Boarding pass
• Departure boards once you arrive at ATL

📝 Local tip for Atlanta-area travelers:
If you’re getting dropped off or parking for a domestic Delta flight, it’s usually fastest to use the Domestic Terminal – South side.

For International Delta Flights

Delta also runs many international routes from Atlanta. These often use:

• International Terminal (Maynard H. Jackson Jr.)
• Concourses E and F

In general:

• International departures on Delta:
  • Check in at the International Terminal (especially if flying directly abroad)
  • Go through security there
  • Your gate will usually be in Concourse F or Concourse E
• International arrivals on Delta:
  • Typically arrive at Concourse F or Concourse E
  • You’ll clear U.S. Customs and Border Protection (CBP) in the International Terminal area
  • After customs, you can connect onward to another Delta flight if needed

If you live in Atlanta and are flying internationally, your booking or confirmation usually tells you which terminal to check in at, but Delta international flights commonly use the International Terminal for check-in.

How to Choose the Right Drop-Off Point

1. If You’re Being Dropped Off by Car (Friends, Family, Rideshare)

• Domestic Delta flight
  • Ask to be dropped at:
    “Domestic Terminal – South, Delta departures.”
• International Delta flight
  • Ask to be dropped at:
    “International Terminal, Maynard H. Jackson Jr. Terminal.”

This avoids riding the airport shuttle across the property after you arrive.

2. If You’re Driving and Parking

Both sides of ATL have parking options, but for simplicity:

• Flying domestic on Delta:
  • Follow signs for Domestic Terminal – South parking (Hourly, Daily, Economy, or Park-Ride lots)
• Flying international on Delta:
  • Follow signs for International Terminal parking
  • There is a dedicated parking deck for the International Terminal

If you accidentally park at the wrong side, ATL runs terminal shuttle buses between the Domestic and International terminals—but it can add time, so plan for this if you’re cutting it close.

Connecting Flights on Delta in Atlanta

A lot of travelers connect through Atlanta on Delta, sometimes without ever leaving the airport.

Already in the Airport? You Probably Don’t Change Terminals

If you’re just connecting from one Delta flight to another:

• You do not need to go back to the street-level terminals
• Simply follow signs to the Plane Train and ride to your next concourse
• All concourses T through F are linked behind security

Only if you must:

• Collect checked bags and re-check after customs on certain international routes
• Or exit to meet someone or change airports/ground transport

would you need to go out to a terminal entrance again.

Getting Between Domestic and International Sides

If you live in metro Atlanta, you may wonder: What if I go to the wrong terminal?

Inside the Secure Area

If you’re already past security:

• Use the Plane Train to ride between:
  Concourse T ↔ A ↔ B ↔ C ↔ D ↔ E ↔ F
• From Concourse F, you can walk directly to the International Terminal baggage claim and arrivals area

You do not have to re-clear security when changing concourses.

Outside the Secure Area (Curbside Level)

If you end up at the wrong terminal entrance:

• Look for the Free Terminal Shuttle between:
  • Domestic Terminal (North and South)
  • International Terminal (Maynard H. Jackson Jr.)

Allow extra time—this shuttle runs regularly but still adds a buffer to your schedule.
