Terminal Access Note

IAH has five terminals (A, B, C, D, and E) connected by the Subway, an underground automated train. The Subway runs between all terminals and takes about 2 minutes between stops. You can ride it freely after clearing security, making it easy to visit lounges in other terminals without re-screening.
