I'm flying United from the B Gates — do I check in at Terminal C?
During the Terminal B renovation that began in January 2025, the Terminal B check-in lobby is closed, and many B-gate passengers check in and clear security at Terminal C, then ride the Skyway train to the B Gates. Confirm your check-in location with United before heading to the airport.
