What United Is Building at IAH

United's rebuild of 1969-vintage Terminal B. The big piece is done: the 765,000 sq ft, 22-gate North Concourse opened to passengers on October 22, 2026, with United bringing its gates into service in stages through Christmas. Still to come are a nearly doubled central processor for check-in, security and baggage claim, the modernized South Concourse (48 Terminal B gates in all), and a new bag system. United is in for $1.9B+, the City of Houston ~$624M. The B lobby has been closed since January 2025 and is still closed — B passengers check in at Terminal C.

The headliner, open since October 22, 2026: 54,000 sq ft near gate B11 with 800 seats, two bars, two buffets and a 1,350 sq ft outdoor terrace — the largest club in United's network, and in United's words the largest club of any airline in the Americas. More than 50% bigger than Denver's B-East, which held United's crown until now.

United's second grab-and-go Club Fly (after Denver), near gates B12/B20: barista coffee, grab-and-go food, a charging counter — no seating, no alcohol. Built for connectors who want ten good minutes, not two loitering hours.

Houston Airports' own $1.46B program — not United's money, but United's international passengers live in it: the six-gate D-West pier (open since October 2024), a new international ticketing hall, and a rebuilt roadway. 'Open' here means substantially complete — the airport's stated February 2026 finish for the last item, baggage-system certification, not a ribbon-cutting.
