Not a great airport....old, dated bathrooms, TSA Pre-check on only one side of A terminal, pretty small number of services. Needs a refresh as of Winter 2019...
The Fox Sports Skybar is a good dining atmosphere in terminal E, but the chili was no good. The burgers look pretty tasty though. $7 draft beer, not as bad as the ballpark but it will add up quick.
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.
