Travelers departing through Terminal B at Houston’s George Bush Intercontinental Airport (IAH) will need to allow extra time to get to their gates. The terminal’s lobby will be closed for several months beginning this Tuesday, January 21.

During the closure, which is expected to last until sometime in 2026, the lobby will undergo extensive renovations that include changes to the ground-level check-in and baggage claim areas as well as three times more curb frontage, according to a press release. The terminal will also be home to the largest United Club in the world and 22 new gates.

Since the Terminal B gates will remain open while its lobby is closed, travelers who are departing from Terminal B will need to check in at Terminal C. Signage on the way to the airport will remind people of the Terminal B lobby closure.

United Airlines, which is funding the $2.5 billion Terminal B renovation project, will run a free shuttle between the Terminal A/B parking garage and Terminal C to assist travelers. However, people are encouraged to park in the Terminal C garage if spaces are available.

Once passengers have checked in at Terminal C, they may use the above-ground Skyway train to get to Terminal B. The airport suggests travelers with Terminal B departures arrive two to three hours early to allow enough time for parking, check in, and getting to their gate.

"United Airlines is thrilled to lead this monumental investment in Houston's future with the Terminal B Transformation Program," United vice president of airport operations Phil Griffith said in a statement. "This expansion not only enhances the passenger experience but also strengthens Houston's role as a global hub. With cutting-edge amenities, an expanded baggage handling system, and the addition of 22 new gates, this project will serve millions of passengers annually while creating thousands of local jobs. The Terminal B Lobby closure marks a transformative milestone for both United Airlines and its partners, and we are fully committed to supporting our passengers throughout this process, ensuring a smooth travel experience with resources such as intuitive signage, on-site wayfinding assistance, and timely reminders via the United app.”
