In 2025, the world’s busiest airport was not in Dubai, London, or Tokyo. It was Atlanta.

Why Atlanta Still Ranks #1
The Atlanta airport, which celebrates its 100th anniversary in 2026, has been the world’s busiest airport every year since 1998, except for 2020 during pandemic-era travel restrictions.
This table lists the world’s busiest airports by 2025 passenger count.

Named after two former mayors, Hartsfield-Jackson serves as the main hub and headquarters for Delta Air Lines, the world’s top airline by both revenue and brand value.
Smaller airlines like Frontier and Southwest also maintain operating bases at the airport. Consequently, more than 1,000 flights depart from Hartsfield-Jackson each day.
The U.S. Big Four Airports
Atlanta is not the only U.S. airport near the top. The U.S. accounts for four of the 10 busiest airports worldwide, more than any other country in the ranking.
Dallas Fort Worth (85.7 million), which anchors two of the country’s largest cities, ranks fourth worldwide in passenger traffic, while Denver’s sprawling airport lands in the 10th position with 82.4 million passengers in 2025.
Sixth-ranked Chicago O’Hare (84.8 million) held the title of world’s busiest airport for a quarter-century before losing it to Atlanta in 1998. It continues to be the airport with the most takeoffs and landings, recording more than 860,000 aircraft movements in 2025.
Eurasia’s Biggest Airports
No African or South American airport cracks the world’s 10 busiest airports, which are instead dominated by East Asian and Middle Eastern hubs like Tokyo Haneda (91.7 million), Shanghai Pudong (85 million), and Istanbul (84.4 million).
London Heathrow is Europe’s busiest airport, handling 84.5 million passengers in 2025.
Meanwhile, Dubai (95.2 million) has become the world’s second-busiest airport, while remaining the busiest for international passengers. This reflects the United Arab Emirates’ strategy of positioning Dubai as a global aviation hub connecting Asia, Europe, and the West.
