Top 5 Aviation Hubs by Passenger Traffic
The annual passenger traffic at the world’s largest airports exceeds the population of most European countries. Here’s something to consider: Germany — the most populous country in the EU — has 83.5 million residents, while the world’s busiest airport handles 108 million passengers each year.
The Airports Council International (ACI) regularly publishes consolidated statistics on passenger volumes at airports worldwide and uses that data to identify the busiest aviation hubs.
Heathrow Airport (London, United Kingdom)
Fifth place goes to Heathrow Airport in London, which handled nearly 84 million passengers in 2024 — including arrivals, departures and connecting passengers. That figure is a record for Heathrow: in the pre-pandemic year of 2019, it handled 3 million fewer passengers. Heathrow is also Europe’s busiest airport and leads the continent in the number of destinations, with direct flights to 230 locations worldwide. Its two runways are currently operating at 99% capacity, prompting plans to build a third runway to significantly increase the airport’s already considerable capacity.
Haneda Airport (Tokyo, Japan)
Fourth place is held by Haneda Airport in Tokyo, which saw 85 million passengers in 2024. Haneda is widely regarded as the world’s most punctual major hub: 90.3% of its flights depart on time, versus a 77.1% average for airports of similar size. In 2024, Haneda also won a World Airport Award, being named the cleanest airport in the world.
Dallas–Fort Worth International Airport (Texas, USA)
Dallas–Fort Worth International Airport (DFW), which welcomed nearly 88 million passengers in 2024, comes in third. Among the world’s top three hubs, DFW demonstrated the most impressive post-pandemic growth — traffic is up 17% compared with 2019. The airport is so large it has its own ZIP code, along with independent fire, police and emergency medical services — essentially functioning as a city within a city.
Dubai International Airport (UAE)
Dubai International Airport ranks second, having handled over 92 million passengers in 2024 — another all-time record. For several consecutive years, Dubai has also led the world in international passenger traffic: the vast majority of its flights are cross-border routes. More than 100 airlines operate from the airport, connecting it to 272 destinations in 107 countries.
Hartsfield–Jackson Atlanta International Airport (Atlanta, USA)
And in first place is Hartsfield–Jackson Atlanta International Airport, which handled 108.1 million passengers. Except for 2020, it has been the world’s busiest airport — both by passenger numbers and aircraft movements — every year since 1998. It is also the planet’s largest aviation hub, supporting over 2,200 flights daily to 225 cities. The airport features the automated Plane Train, the most heavily used airport people-mover in the world. It transports around 250,000 passengers a day along a 4.5-kilometer underground loop.
