Busiest airport in the world

What to remember

In 2025, 106,302,208 passengers passed through Hartsfield-Jackson Atlanta International Airport in Georgia. No airport in the world handled more that year, and traffic rose by 1.6% on the year before.

From 1998 to 2025, Atlanta was the busiest airport every year with one exception: 2020, when travel restrictions cut its traffic for a year. It regained first place in 2021. Located 16 km south of Downtown Atlanta, it is the primary hub of Delta Air Lines, which also has its corporate headquarters there. It is named after two former Atlanta mayors, William B. Hartsfield and Maynard Jackson.

Anyone who arrives, departs or transits through an airport counts as a passenger. The United States has 14 airports in the 2025 top 50, ahead of China with 12. Counting all airports of a city together, London has the world's busiest city airport system.
