How big is Atlanta International airport?

Hartsfield–Jackson Atlanta International Airport, also known as Atlanta Hartsfield–Jackson International Airport, Hartsfield–Jackson International Airport, Atlanta Airport, Hartsfield–Jackson, and formerly as the Atlanta Municipal Airport, is the primary international airport serving Atlanta, Georgia, United States.



Hartsfield-Jackson Atlanta International Airport (ATL) is a massive facility covering approximately 4,700 acres (about 7.3 square miles) of land. While it is not the largest airport by land area (a title held by Denver International), it is consistently ranked as the world's busiest airport by passenger traffic. The terminal complex itself covers 130 acres and includes two main terminals (North and South) and seven parallel concourses (T, A, B, C, D, E, and F). These are connected by an underground automated people mover known as the Plane Train, which runs for roughly 1.4 miles. In 2026, the airport continues to operate five parallel runways that run east-to-west, allowing for more than 100 arrivals and departures per hour during peak operations, making it the most efficient and high-volume aviation hub in the global transport system.
