Understanding the Layout: Domestic Terminal vs. International Terminal

ATL can feel overwhelming, especially if you’re new to Atlanta or connecting through. The key is to understand the two main terminal areas:

Domestic Arrivals on Delta in Atlanta

1. Take the Plane Train or walk to the Domestic Terminal.
2. Follow signs for “Baggage Claim”.

Connecting in Atlanta on Delta Domestic Flights

Domestic-to-Domestic Delta Connections

If you’re connecting between two Delta domestic flights at ATL:

• You do not leave the secure area.
• Check the monitors or app for your next gate and concourse.
• Use the Plane Train to move quickly between concourses.
• Typical connection path might be:
  • Arrive at Concourse B → depart from Concourse A, and so on.

Since ATL is a major Delta hub, many itineraries through Atlanta involve very short connections. You’ll want to move directly to your next gate, especially if your arrival gate is far from your departure gate.

Domestic-to-International with Delta in Atlanta

If you’re flying Delta domestic into Atlanta and then connecting to an international Delta flight:

• You may arrive at a domestic concourse (T, A, B, C, or D).
• Your international flight could depart from:
  • Concourse E
  • Concourse F (International Terminal)

You’ll still remain airside (inside security) and follow signs to your next gate. You do not usually need to switch to the outside, landside terminal area during a normal connection.

International-to-Domestic with Delta into Atlanta

If you arrive in Atlanta on an international Delta flight, your process may be different:

• You’ll typically arrive at Concourse F or E.
• You’ll go through U.S. Customs and Border Protection and baggage claim at the international facilities.
• After customs, if you’re connecting to a domestic Delta flight, you’ll typically re-check your luggage and then:
  • Either proceed directly to domestic gates via the airport’s secure connection path, or
  • Follow airport signs guiding you to the Domestic Terminal transit.

Even though this involves extra steps, your domestic flight will still depart from the Domestic Terminal concourses (T, A, B, C, or D).

If you have a baggage issue on a Delta domestic flight in Atlanta (lost bag, delayed bag, damaged luggage), you’ll generally need to:

• Go to the Delta Baggage Service Office in the Domestic Terminal South baggage claim area.
• Follow airport signs for “Lost & Found / Baggage Service” near the Delta carousels.

You can also contact Delta through their published customer service numbers if you prefer to start a claim by phone.

Tips for Navigating Delta Domestic at ATL

Here are some practical, Atlanta-focused tips to keep your Delta domestic trip smoother:

• Plan extra time for traffic
  Metro Atlanta traffic on I-75/85, I-285, and surrounding routes can be heavy, especially during weekday rush hours. Build in additional time to reach the Domestic Terminal South.

• Use the Plane Train
  ATL’s Plane Train runs frequently and connects every concourse plus the Domestic Terminal. It’s usually faster than walking if your gate is far.

• Check your concourse early
  Your boarding pass and airline app will show which concourse you’re using. Knowing this ahead of time helps you plan where to eat, shop, or rest.

• Pack for security
  Security lines at the Domestic Terminal South can be busy. Have your ID ready, follow TSA guidelines, and consider entering earlier if you’re traveling during peak times (early morning and late afternoon are often busier).

• Know where you’re meeting rides
  If you’re using rideshare services, follow the posted signs after collecting baggage. ATL designates specific pickup areas for app-based rides near the Domestic Terminal.
