The world's busiest airports by flights, counted from a year of real flights

The top 20 by flights

These are airliner take-offs and landings a day, on average, counted from the ADS-B records our prints are drawn from: the 379 days we hold between 27 September 2025 and 26 October 2026. Each airport links to its print page.

Roughly half of each figure is departures, the lines our prints draw: about 1,200 a day at O'Hare, 1,070 at Atlanta.

How we counted

Aircraft broadcast their position by ADS-B, and volunteers' receivers pick it up and share it through ADSB.lol. From those records our flight database works out every take-off and landing at each airport. We count airliners only, on every day the database holds, leaving out days when the whole database was short. The same records decide which days can be printed. How a day of flights becomes a print explains the data in more detail.

Our count is not an official statistic, but it agrees with the best-known rankings. Those come from Airports Council International (ACI), the airports' own trade body, and its preliminary figures for 2025 put O'Hare first by aircraft movements, then Atlanta and Dallas Fort Worth: the same top three, in the same order.

Busiest by flights is not busiest by passengers

By passengers, the order changes. ACI's preliminary figures for 2025 put Atlanta first with 106.3 million, then Dubai with 95.2 million and Tokyo Haneda with 91.7 million.

The difference is the size of the aircraft. Haneda carried roughly 86% as many passengers as Atlanta with only about 60% as many flights in our count: its domestic routes are flown with big jets, many of them wide-bodies. Thirteen of our top 20 are in the US, where airlines run large domestic networks through a few hubs, often with smaller jets flying more often. Each flight carries fewer people, so a US hub handles more flights for each passenger than most airports elsewhere.

Europe and Asia

Europe's three biggest hubs are almost level: Paris Charles de Gaulle at 1,269 a day, Heathrow at 1,266 and Schiphol at 1,256. Heathrow manages it with two runways, where Charles de Gaulle has four and Schiphol six. Frankfurt (1,175) and Madrid (1,136) follow, then Barcelona at 958.

In Asia and the Pacific, Tokyo Haneda (1,283) and Seoul Incheon (1,173) lead our list, ahead of Bangkok Suvarnabhumi (993), Sydney (791) and Mumbai (774).

Who is missing, and why

A ranking from receivers can only count what the receivers hear, so we leave out any airport we don't see well all year:

• Mainland China. Few volunteers there share flight data, so Shanghai Pudong and Guangzhou, both in ACI's top ten by passengers for 2025, and Beijing are not in our list at all.
• Istanbul. Busy, but its departures are seen far less often than its arrivals, so we can't count it fairly.
• Dubai, Hong Kong and Singapore. All three are in our shop, but we saw them well on only some days of the year, and an average over those days would not compare with the airports above.

Every one of them is a print

Behind each number is a day you can see. Our prints draw every take-off of one day at one airport, and the busiest airports make the densest pictures: on a busy day at O'Hare, more than 1,300 lines leave the runways. Pick an airport from the list, then a day that means something to you.
