Where to Find Southwest Airlines at ATL

When arriving at Hartsfield-Jackson Atlanta International Airport for a Southwest flight, you’ll be using Terminal North (Domestic Terminal).

It’s best to arrive at least two hours before your flight, especially during peak travel times. The lines can get long, especially at security checkpoints.

Security Screening and Concourse Access

Once you’ve checked in, it’s time to head through security. Passengers flying from the Southwest Airlines Atlanta Airport Terminal will use the North Security Checkpoint. This checkpoint is often less crowded than the main security lines, but it’s always wise to allow extra time just in case.

Once you’re past security, you’ll take the airport’s Plane Train, an automated people mover system that transports passengers to the various concourses. For Southwest flights, you’ll be heading to Concourse C.

The Plane Train ride takes only a few minutes and is well-signed for easy navigation. Concourse C is exclusively used by Southwest Airlines, making it convenient for travelers to find their gate and relax without needing to navigate multiple airline zones.

Southwest Boarding Process at ATL

Southwest’s boarding process is unique, and it applies at the Atlanta Airport Terminal just like at any other location. Passengers are assigned a boarding group (A, B, or C) and a number (1-60). Boarding starts with Group A and proceeds in numerical order. There are no assigned seats, so the earlier your group and number, the more choices you’ll have when finding a seat on the plane.

For the smoothest boarding experience, be sure to check in exactly 24 hours before your flight to get the best possible position, unless you’ve purchased EarlyBird Check-In.

Once boarding begins, passengers line up in the designated lanes according to their group and number. This process is well-organized at the Southwest Airlines Atlanta Airport Terminal, and staff members are always available to guide you if you’re unsure.
