United Airlines at Atlanta Airport: Which Terminal You’ll Use and How to Get Around

If you’re flying United Airlines in Atlanta, you’ll be using Hartsfield–Jackson Atlanta International Airport (ATL). Even though ATL is the main hub for Delta, United has a clear and consistent setup here once you know where to look.

Quick Answer: What Terminal Is United Airlines in Atlanta?

At Hartsfield–Jackson Atlanta International Airport (ATL):

• United Airlines check-in and ticketing:
  Domestic Terminal – North (North Terminal)
• United Airlines gates:
  Primarily in Concourse T, sometimes in other concourses (A–D), but always reached after security via the Plane Train or walkways.
• Arrivals and baggage claim for United:
  Domestic Terminal – North baggage claim

You’ll only use the International Terminal (Concourse F) with United if you are:

• Connecting to or from an international flight on a partner airline, or
• Arriving on an international flight that clears customs in Atlanta.

Most United passengers in Atlanta will start and finish in the Domestic North Terminal.

Understanding ATL: Terminals vs. Concourses

ATL can be confusing because people use “terminal” and “concourse” interchangeably. For United, it helps to separate them:

Terminals (where you enter the airport from the street)

• Domestic Terminal – North
• Domestic Terminal – South
• Maynard H. Jackson Jr. International Terminal (for most international departures/arrivals)

These are the building fronts with ticket counters, security checkpoints, and baggage claim.

Concourses (where the gates are after security)

ATL has Concourses T, A, B, C, D, E, and F connected in a line.

• United gates are usually in Concourse T, sometimes in neighboring domestic concourses.
• You do not re-clear security when moving between concourses; you ride the Plane Train or use the underground walkways.

Think of it this way:

For United in Atlanta:
North Terminal for check-in and baggage → Concourse T (and nearby concourses) for gates

Where to Check In for United at ATL

If you’re departing on United from Atlanta:

• Go to the Domestic Terminal – North, often called the North Terminal.

Security Checkpoints for United Passengers

Once you’ve checked in or if you’re traveling with mobile boarding passes and no checked bags:

• Use the North security checkpoint in the Domestic North Terminal.
• After you clear security, you’ll enter the Concourse T area.

  • Walk directly to Concourse T gates, or
  • Take the Plane Train to Concourses A, B, C, D, E, or F if your United flight uses a different concourse.
