United Airlines has reached a significant milestone in the redevelopment of Terminal B at George Bush Intercontinental Airport (IAH), which aims to enhance passenger experience and capacity. As a result, the Terminal B lobby, where some passengers currently check in for their flights, pass through TSA security and claim their baggage upon arrival, will temporarily close on January 21, 2025. 

The Terminal B Ticketing Lobby is expected to reopen in 2026 with a modern design and upgraded passenger amenities. 

During the lobby closure, signage along Will Clayton Parkway and JFK Blvd will direct United Airlines passengers to check in at Terminal C. 

The IAH A/B Parking Garages will remain open. However, United Airlines travelers are encouraged to arrive and park or reserve parking in advance in the Terminal C parking garage as a point of terminal entry. The Houston Airports ecopark lots are also an option. 

United Airlines passengers flying from IAH Terminals A, B, C or E should check in, drop luggage and pass through TSA security at Terminal C. United Airlines encourages all passengers to arrive at Bush Airport 2-3 hours before their flights. Passengers should use the above-ground Skyway train for easy access to Terminals A, B or E. United Airlines gates B3–B31 will remain operational throughout the lobby closure.
