Travel hack

Getting from Houston airports to the city center

Fastest options: taxi and ride-hailing services. Best value: METRO bus routes.

Houston is served by two major airports offering various airport transfers to city center destinations. George Bush Intercontinental Airport (IAH) lies 37 km north of downtown Houston, while William P. Hobby Airport (HOU) is located 18 km southeast of the city center. Transport options include METRO buses, taxis, ride-hailing services, private transfers, and rental cars. Houston does not have direct rail service from either airport to downtown, so ground transportation relies primarily on road-based options. Journey times vary significantly depending on traffic conditions, particularly during rush hours.
