Quick Answer
Atlanta Airport operates through two main terminals (Domestic & International) linked airside by 7 concourses (T, A, B, C, D, E, F). You never need to exit security to change concourses during a domestic transfer. The Plane Train, an automated underground railway running 24/7, connects all concourses within minutes. Always allow extra time if your transfer involves international arrivals due to U.S. Customs and re-screening checkpoints.
Understanding the Layout: ATL's Terminal & Concourse Design
Atlanta Airport’s layout is famous for its parallel concourse arrangement designed for ultimate efficiency. The complex features two main entrance structures the Domestic Terminal (divided into North and South for ticketing/check-in) and the International Terminal (Maynard H. Jackson Jr.).
Positioned between these two terminal complexes are seven linear concourses (T, A, B, C, D, E, F). Because all concourses are linked continuously airside via the underground Transportation Mall, moving between gates is direct and straightforward.
