The online check-in process at United.com applies to most passengers, but some restrictions apply. Online check-in applies to individuals or groups with fewer than nine passengers on a trip with four flight segments or fewer. The first flight must be a United flight. Any reservations that were paper-ticketed require check-in at the airport. Some passengers requesting special services also need to check in with an agent.
Passengers can check in online starting 24 hours before the flight departs. Most flights require United passengers to check in at least 30 minutes before departure. Some departure airports require passengers to check in 45 minutes before departure.
The online check-in process allows passengers to print boarding passes at home. If you don't have access to a printer, arrive at the airport early to print one from a self-service kiosk. Departure flights from some cities allow United passengers to choose a mobile boarding pass.
Passengers with checked luggage can use the online check-in process. Indicate the number of checked bags when you check in online. At the airport, check the bags at a kiosk or with a United representative.Learn more about Geography
