The top 10 busiest airports in the world by passenger numbers
Read on to discover which airports had the highest passenger numbers in 2025, based on the total number of departing, arriving, transferring and direct passengers.
The following list is based on figures from Airports Council International (ACI) and displays the top 10 busiest airports in order of total passenger numbers in 2025. Passenger figures are calculated by summing the totals of departing passengers, arriving passengers, transferring passengers and direct transit passengers at each airport throughout the course of the year.
Hartsfield-Jackson Atlanta International Airport remains the world’s busiest airport for passenger traffic, followed by Dubai International Airport and Tokyo Haneda Airport.
ACI World Director General Justin Erbacci said: “We congratulate the world’s busiest airports for managing growing air travel demand amid increasing operational complexity. These hubs keep people and goods moving, supporting global trade, tourism, and economic growth in their communities and regions. To help keep pace with rising demand, governments must prioritise sustained investment in airports and the broader aviation ecosystem.”
