The World’s Busiest Airports, by Passenger Count

In 2022, worldwide passenger traffic came near to 7 billion, an increase of almost 54% from 2021, and a 74% recovery from pre-pandemic levels.

These 10 airports made up 10% of all passenger traffic in the world last year. Half of these airports are in the U.S. and their numbers were largely buoyed by domestic travelers, according to the ACI Director General.

While Atlanta’s airport saw the highest number of passengers at nearly 94 million, London’s Heathrow airport saw passenger traffic grow the most annually by over 217%.

In this dataset, such big percentage increases between 2021 and 2022 are usually linked to the scaling back or full removal of COVID-19 restrictions.
