This US airport was once again named the busiest in the world: See the top 10

Hartsfield-Jackson Atlanta International Airport has officially been named the busiest airport in the world for the second year in a row.

OAG’s annual ranking of major airports again has ATL in the top spot after it handled 62.7 million seats in 2024. The aviation analytics firm specifies that it bases its rankings on capacity airlines scheduled through the airports on the list, not the exact number of passengers who flew.

Four of the top ten busiest global airports were in the U.S. last year, with Dallas/Fort Worth at number five, Denver at number six, and Chicago-O’Hare at number 10.

1. Atlanta Hartsfield-Jackson International (ATL)
2. Dubai International (DXB)
3. Tokyo International – Haneda (HND)
4. London Heathrow (LHR)
5. Dallas Dallas/Fort Worth International (DFW)
6. Denver International (DEN)
7. Guangzhou Baiyun (CAN)
8. Istanbul (IST)
9. Shanghai Pudong International (PVG)
10. Chicago O’Hare International (ORD)

“Atlanta’s continued global leadership reflects the airport’s strength as a major connecting hub for both domestic and international capacity, supported by a strong set of base airlines,” OAG’s Chief Analyst, John Grant, said in a statement. “Recent developments in both Dallas/Fort Worth and Denver highlight the competitive nature of the market in the United States which results in choices for the connecting traveler market.”

According to OAG, Atlanta saw 2% more capacity in 2024 than the year prior, and all 10 of the busiest global airports saw growth last year.

Shanghai Pudong had the most growth in the top 10, jumping from number 15 in 2023 to number 9 in 2024, with a 29% increase in capacity.

Dallas-Fort Worth, Denver and Chicago all saw capacity up by 5-9%.
