George Bush Airport (IAH) Terminal B : Gates, Concourses, Levels & Airlines
The IAH Terminal B handles the regional and domestic flights of United Airlines. Terminal B at George Bush Intercontinental Airport (IAH) is being rebuilt as part of Houston’s bold plan to improve the future of travel. The project will add 22 new gates in the North Concourse, improve 18 gates in the South Concourse, and almost double the size of the central area used for check-in, security, and baggage claim. The new design also features massive glass, approximately 67,000 square feet in total, with windows reaching up to 45 feet in height. This will allow more natural light inside and create a bright, welcoming space for passengers.
