ATL Air Traffic

Short answer: Hartsfield-Jackson Atlanta International Airport (ATL) was again the world's busiest airport by passengers in 2025, with 106.3 million passengers. That was down 1.6% from 2024, and Dubai (95.2 million) and Tokyo Haneda (91.7 million) were closing the gap, according to Airports Council International.

ACI says four of the five US airports in the top 20 are mainly domestic hubs, with 80-95% domestic passengers, which describes ATL's traffic. By aircraft movements, though, Chicago O'Hare ranked first in 2025. ATL has five parallel runways and two terminals, the Domestic Terminal and the Maynard H. Jackson Jr. International Terminal, with seven concourses linked by an underground train. It's Delta Air Lines' main hub and is named after two Atlanta mayors, William B. Hartsfield and Maynard Jackson.
