Operating as a pivotal global connecting hub, it has held the world's passenger traffic leadership continuously since 1998 (with the exception of 2020). ATL provides an extensive domestic and international network, offering nonstop flights to major global gateways including London, Paris, Amsterdam, Frankfurt, Tokyo, Seoul, Mexico City, Bogotá, and Panama City, in addition to reaching virtually every domestic commercial airport across North America.

Terminals
The airport complex operates 24 hours a day and consists of two main terminal complexes situated at opposite ends of the property, linked by a secure central spine that connects seven parallel linear concourses:
- Domestic Terminal: Located on the west side and divided into Domestic North and Domestic South for ticketing, check-in, and baggage claim. It features the central Main Atrium and provides direct secure access to Concourses T, A, B, C, and D.
- Maynard H. Jackson Jr. International Terminal: Located on the east side, handling international arrivals and departures and providing direct access to Concourses E and F.
To move between concourses and terminals post-security, passengers use The Plane Train, an automated underground people mover that travels between all concourses in approximately 5 minutes, supplemented by parallel pedestrian moving walkways. In the pre-security public area, free terminal shuttle buses run continuously between terminal curbsides. Learn more about terminal connections.
Annual Passenger Traffic (2025): 106,3 million passengers.

Customer service and information desks are located in the Domestic Terminal Atrium and in the international arrivals areas of Concourses E and F, with airport staff also stationed at Plane Train platforms. General information services are available Monday through Friday from 8:15 am to 5:00 pm.
