George Bush Intercontinental Airport IAHKIAH

George Bush Intercontinental Airport (IAH) is Houston’s main long-haul airport and a major United Airlines hub, with Star Alliance strength and a strong Latin America role alongside broad domestic and international service. The five terminals are easier to connect than they first look: Skyway links terminals airside, while the Subway links them landside and also reaches the on-airport Marriott. For downtown Houston, the most practical choice depends on your trip: METRO 500 Downtown Direct is the cleanest public-transport option to the George R. Brown Convention Center area, while taxi or ride-app service is usually best for door-to-door hotel access. Connections are generally workable on one ticket, especially United-to-United, but international arrivals clear immigration in Terminal E and should not be treated like a simple domestic transfer.
