Global air travel has rebounded, with total passenger traffic surging past pre-pandemic levels to hit a record 9.4 billion travelers in 2024. The data from the Airports Council International (ACI) reveals which airports handled the massive surge, with U.S. hubs continuing to dominate and Istanbul showing explosive growth.
The aviation industry is officially in recovery! Data from the Airports Council International (ACI) confirms that global passenger traffic in 2024 finally surpassed pre-pandemic levels, hitting a record 9.4 billion travelers. This marks a robust increase of about 2.7% compared to the figures recorded in 2019.
Despite this global surge, the perennial winner, Atlanta Hartsfield-Jackson, maintained its title as the world’s busiest airport, serving 108 million passengers. Interestingly, even at number one, Atlanta’s traffic was still down two percent compared to its 2019 figures.

The U.S. continues to dominate the rankings, but emerging global hubs are making huge gains, particularly Istanbul Airport, which saw traffic increase by over 50% since 2019—a jump the ACI credits to “airline expansion, infrastructure growth and enhanced global connectivity.”
