These are the world's Top 10 busiest airports of 2023

Not only does Atlanta host Delta's sprawling network, but its Southeast location puts it within a two-hour flight of 80% of the US population.

• The Official Airline Guide published its list of the busiest airports in the world for 2023.
• For the 25th time since 1998, Atlanta Hartsfield-Jackson International Airport took the crown.
• Half of this year's Top 10 busiest global airports are in the US.

The Official Airlines Guide has published its annual list of the Top 10 busiest airports in the world for 2023 — and half were in the US.

Based on total airline domestic and international seat capacity, OAG crowned Atlanta Hartsfield-Jackson International Airport, or ATL, as this year's busiest global airport, with about 62.2 million available seats.

The results should not come as a shock considering the Georgia capital's airport has earned the title every year since 1998, except 2020 when China's Guangzhou Baiyun International Airport briefly dethroned Atlanta amid the coronavirus pandemic.

The other nine airports spanned the US, Europe, and Asia — and represent a collective 500 million seats offered by global carriers in 2023, according to OAG data.

Of the Top 10 airports, every one exceeded 2022 numbers. A few airports even managed to surpass 2019 levels, with the biggest jump at Denver International Airport — which boasted 17% more capacity compared to pre-pandemic levels.

Dallas/Fort Worth International Airport and Turkey's Istanbul Airport each increased by 10%, while Dubai International Airport's available seats jumped 5%, according to OAG data.

Atlanta, for its part, is still down 3% compared to the 63.3 million seats that were available there in 2019. But its 2023 numbers still beat the second-busiest airport by about five million seats.

Atlanta's high-traffic airport is popular for myriad reasons. Not only does it host Delta Air Lines' sprawling network, but its Southeast location puts it within a two-hour flight of 80% of the US population.

And unlike like London, Dallas, Chicago, and Tokyo, the airport known as ATL doesn't compete for passengers with other airports nearby.
