In 2024, Hartsfield-Jackson Atlanta International Airport (ATL) has once again secured its position as the world's busiest airport, a title it has held for 26 out of the past 27 years. The Atlanta airport, which serves as the main hub for Delta Air Lines, topped the Airports Council International's annual rankings by handling over 108 million passengers, marking an increase of slightly over 3% from 2023.
This achievement coincides with a record number of airline passengers globally, as 2024 witnessed close to 5 billion travelers, according to ACI. This figure exhibits a 9% rise from the previous year and nearly 4% over the levels seen prior to the pandemic in 2019. In the U.S., the Transportation Security Administration recorded its 10 busiest days at airport security checkpoints in 2024, with December 1 marking the highest volume ever, exceeding 3 million passengers on that single day.
Following ATL, Dubai International Airport (DXB) ranked second with over 92 million passengers. Dallas Fort Worth International Airport (DFW) came third, with Denver International Airport (DEN) and O'Hare International Airport (ORD) placing sixth and eighth, respectively, among the world's top 10 busiest airports.
