Compared with other airports in TX notably DFW, this place is outdated, with little waiting space at the gates. Some interesting food options though if you have enough time.
Sign-up for TSA Pre-check! 60 seconds or less in security. If too few people use it they will remove the service from the C terminal. Currently not in the E terminal.
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.
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.
Airport shut down for over an hour, our plane had to fly almost to Beaumont, sat on tarmac probably 30-40 min, meanwhile my connecting flight home was being boarded. Chaotic and confusing
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.
