International flights at Hartsfield-Jackson Atlanta International Airport (ATL) primarily operate out of Concourse F and Concourse E. Concourse F is directly connected to the Maynard H. Jackson Jr. International Terminal and is the main hub for foreign carriers and major international departures. Concourse E, which previously served as the primary international hub, is still heavily used for international arrivals and departures, particularly for Delta Air Lines. If you are arriving from an international destination and Atlanta is your final stop, you will exit through the International Terminal (Concourse F). If you are connecting to a domestic flight, you may arrive at E or F, clear customs, and then take the "Plane Train" or the underground walkway to Concourses T, A, B, C, or D. It is important to note that the International Terminal has its own separate entrance and parking off Interstate 75, which is physically distinct from the Domestic Terminal entrance off Interstate 85.
