IAH Transport Between Terminals

At Houston George Bush Airport passengers have several options to transfer between terminals. 

All five terminals at Houston Airport are connected by an underground train (Subway) and the Skyway (elevated train).


This is the Airside Connection

The Skyway connects Terminals A, B, C, D, E for passengers with connecting flights in different terminals and provides airside connections. This allows travellers to move within the Airport without having to re-enter security. Service is free and operates every day.


Skywalk Station is located in Level 3 of each Terminal.


This is the Landside Connection

The Subway provides transportation between terminals from pre-security areas. It departs from Terminals A, B, C, D/E, and the Airport Hotel Marriott. The Subway operates daily from 3:30am to 12:30am and it’s closed between 12:30am and 3:30am.


Subway Station is located in Level LL of all Terminals.
