Air travel was so popular last year, Houston Airports exceeded its previous record by 3 million passengers while improving traffic flow.

HOUSTON—According to air service data, Houston Airports welcomed 63.1 million passengers in 2024. The total combines passenger counts at George Bush Intercontinental Airport (IAH) and William P. Hobby Airport (HOU). The previous record was set in 2023 with 60.1 million passengers.
