Apparently bathrooms are not bigger in Texas. Leave your bags at the front of the bathroom if your in Terminal B and need to pee. They will not fit in with you.

In Terminal B, if you're taking a Continental Express flight, wait until the last minute before you move to your gate. The Continental Exp. "area" reminds me of an overcrowded ghetto.
George Bush Intercontinental Airport is the 8th busiest airport in the U.S. and offers service to more Mexican destinations than any other airport in the nation.
