Key points
- Airports Council International confirmed its final 2025 rankings on July 15, 2026. Global passenger traffic reached about 9.8 billion, up 3.6 percent on 2024 and 7.3 percent above 2019. The 20 busiest airports handled 1.59 billion passengers, about 16 percent of the world total.
- Atlanta stayed first at 106.3 million passengers but fell 1.6 percent year over year and sits 3.8 percent below 2019. Dubai (95.2 million, up 3.1 percent) and Tokyo Haneda (91.7 million, up 6.7 percent) are closing the gap, and Haneda passed Dallas/Fort Worth for third.
- A "busiest airports" list is a media owner's planning frame. For an advertiser, the useful questions are who those passengers are, whether they leave the secure area, and where your audience actually concentrates.
The rankings
| Rank (2025) | Airport | Passengers | vs. 2024 |
|---|---|---|---|
| 1 | Atlanta (ATL) | 106.3M | −1.6% |
| 2 | Dubai (DXB) | 95.2M | +3.1% |
| 3 | Tokyo Haneda (HND) | 91.7M | +6.7% |
| 4 | Dallas/Fort Worth (DFW) | — | — |
| 5–9 | Shanghai Pudong, Chicago O'Hare, London Heathrow (84.5M), Istanbul, Guangzhou | — | — |
Positions four through nine are from ACI's April preliminary release; ACI publishes the full table with every airport's count in its final July report. Two other cuts matter for planners. On international passengers, Dubai is first, with London Heathrow and Seoul Incheon second and third. On aircraft movements, Chicago O'Hare is first, ahead of Atlanta and Dallas/Fort Worth.
International traffic grew faster than total traffic: 4 billion international passengers in 2025, up 5.9 percent. The growth is concentrated in the Gulf and Asia-Pacific hubs, while the large US hubs are flat to slightly down.
Why "busiest" is the wrong first question
Media owners sell airport advertising on total passenger counts, and the ACI list is the most-quoted number in every airport media kit. It is accurate, and it is the wrong first question for a buyer. Three reasons:
1. Total passengers include connections. Atlanta's 106 million includes tens of millions of people who change planes without leaving the secure area. They never see baggage claim, arrivals halls, landside spectaculars, or the roadway. If your plan is built on arrival-path media, the number that matters is origin-and-destination traffic, which the airport publishes and the media kit usually doesn't. Ask for it.
2. Volume isn't audience. Haneda's growth is domestic Japanese traffic plus inbound tourism. Dubai's traffic is almost entirely international and heavily transfer. Atlanta is a domestic connecting hub. The same rank, three completely different audiences, three different reasons to buy or not buy.
3. Growth tells you about pricing pressure, not fit. An airport growing at 6.7 percent a year will raise rates and sell out faster. An airport down 1.6 percent will have better availability and more flexible terms. Neither fact tells you whether your buyer walks through it.

How to use the list on a global plan
The rankings are most useful as a check on weighting once the audience is defined. For a multi-market B2B plan aimed at international business travel, the 2025 data points in a clear direction:
- Gulf and Asia hubs for international reach: Dubai, Heathrow, Incheon, Haneda, and Singapore carry the world's international business traffic and are growing. For a brand selling into Asia-Pacific or the Middle East, these airports should carry more weight in 2027 than they did in 2024.
- US hubs for domestic reach: Atlanta, Dallas/Fort Worth, Chicago, Denver, and Charlotte remain the volume leaders for the domestic business traveler, with soft totals and good availability. Weight them for the audience, buy them for the terms.
- Watch the climbers: Istanbul, Guangzhou, and Shanghai Pudong are in the top ten on traffic and barely on most Western brands' plans. For a global category launch, they are where share of voice is cheapest.
How EAM Advertising handles it
We treat the ACI table as the media owner's starting point, not ours. Planning starts with who the client needs to reach and where that person actually walks, then the airports get weighted by origin-and-destination traffic, by terminal, and by what's available in the weeks that matter. A 125-airport footprint means the plan can follow the audience across Gulf, Asian, European, and US hubs under a single contract. See the airport advertising hub or send a brief.
