If you are trying to find a Houston Airport Map, the first thing to know is which Houston airport you are using. This page focuses on George W. Bush Intercontinental Airport (IAH), not William P. Hobby Airport (HOU). IAH has five terminals: A, B, C, D and E. The airport map can help you locate your gate, baggage claim, parking area and ground transportation before you start walking around the airport.

For connecting passengers, the most important detail is how the airport levels link. IAH has two free train systems: the Skyway, which operates after security, and the Subway, which operates before security. Knowing which one to use can save you a long walk and help you avoid leaving the secure area unnecessarily. 

The official maps also show different levels for ticketing, gates, baggage claim, ground transportation and train stations.
