UNITED Airline Check In +1 - 866 - 551 - 1186

Flying with a UNITED Airline? You can check in online starting 48 hours before your flight—or 24 hours ahead if you’re traveling to or from the U.S. Use their website or app to choose your seat, add bags, and get your boarding pass. If you prefer, you can also check in at the airport at a kiosk or the counter. UNITED Airline suggests arriving three hours early to make sure you’ve got plenty of time before boarding.
