2025 Update

Wikipedia now says that "Since 1998, Hartsfield–Jackson has been the world's busiest airport by passenger traffic, with the exception of 2020, when its passenger traffic dipped for that year due to travel restrictions resulting from the COVID–19 pandemic. In 2023, the airport served over 104.6 million passengers, the most of any airport in the world. Hartsfield–Jackson is also the world's busiest airport by aircraft movements. In 2024, it was again named the busiest airport in the world, and saw 2% more capacity than the previous year."
