This airport is out-dated and extremely overcrowded. There are phone charging stations everywhere so you don't have to worry about running out of juice.
Best part of this airport is leaving it. It's an embarrassment. People are apathetic. Bathrooms are disgusting and suffer from infrequent cleanings and deferred maintenance issues. Food is mediocre.
Si viajan con niños y no tienen asientos juntos asignados, no esperen por personal en la puerta para hacer el cambio, mejor vayan al centro de servicio frente a la puerta E24 y ellos pueden hacerlo.
Give yourself plenty of time in between connecting flights to hunt down a restroom. When you find one, don't be surprised by uncleanliness. I prefer Hobby.
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.
