International travelers BEWARE! This airport is testing a NEW system of border control/customs. It is a disaster. Do not connect through here unless you have Global Entry.

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.
