Redeem now - OAG named Hartsfield-Jackson Atlanta International Airport as the busiest US airport for 2023.
- With a capacity of 62 million, Atlanta was also crowned the busiest airport in the world.
- Atlanta has won the title 25 times since 1998, minus a brief dethronement in 2020.
Atlanta's Hartsfield-Jackson International Airport is the busiest in the US, global data provider OAG said this week.
The airport also got top honors this week in OAG's rankings for the top 10 busiest global airports.
For the US awards, the rankings were based on each airport's total domestic and international airline seat capacity, which collectively accounted for about 413 million seats across the top 10.
It's Atlanta's 25th win as busiest airport since 1998 — taking the top spot not only in the US, but also for the entire world. The airport only lost its No. 1 spot once when China's Guangzhou Baiyun International Airport briefly overtook Atlanta in 2020 amid the pandemic.
Delta's giant hub, Atlanta's favorable Southeast location, and the lack of competing nearby airports all contribute to the top airport's high foot traffic.
In total, Atlanta saw a 62 million seat capacity in 2023, according to OAG, with the next busiest airport being Dallas/Fort Worth International Airport with about 48 million available seats this year.
Comparing numbers to previous years, the top 10 are all above 2022 in terms of capacity, and only a handful are still trailing behind 2019.
