It is the largest hub for American Airlines, which is headquartered near the airport, and is the third-busiest airport in the world by aircraft movements and the second-busiest airport in the world by passenger traffic in 2022 and 2023, according to the Airports Council International. As of 2025, it is the eighth-busiest international gateway in the United States and the busiest international gateway in Texas.
