Hartsfield–Jackson Atlanta International Airport is built around a single terminal complex with seven parallel concourses strung out in a row, all linked by an underground people mover known as the Plane Train. That layout — plus five parallel runways and a location within a two-hour flight of most of the US population — is why Delta Air Lines built its largest hub here and why Atlanta has topped ACI World's passenger ranking every year since 1998 except 2020. The current schedule feed lists 256 airports in 56 countries connected to Atlanta.
The walk between the domestic concourses and Concourse F passes through Zimbabwe Sculpture at the Atlanta Airport, one of the largest permanent exhibitions of stone sculpture from Zimbabwe anywhere in the world.
Hartsfield Jackson Atlanta International Airport is the 1st busiest airport in the world — it handled 106,302,208 passengers in 2025, according to ACI World's annual ranking.
