What Terminal Is United at IAH?
United Airlines has a major hub at George Bush Intercontinental Airport (IAH) and operates across several terminals, including Terminals A, B, C, and E. Terminal C is especially important for United passengers because it currently handles check-in for passengers traveling from Terminal B gates while the Terminal B ticketing lobby is being renovated.
