How online check-in works
Online check-in opens 24 hours before your departure and closes 45 minutes to 2 hours before the flight departs (timing varies by flight and airport). There are no online check-in fees. Check-in is quick and takes just a few minutes via the United Airlines website or mobile app.
Steps to check in online:
- Log in to United Airlines' website or mobile app 24 hours before departure
- Enter your booking reference and last name
- Select your seat (if not already assigned) and review baggage fees
- Print your boarding pass or save it to your mobile device
- Arrive at the airport according to recommended times and proceed to the gate
Practical tip: Complete mobile check-in the night before travel to avoid last-minute delays, and arrive early if you have checked baggage requiring processing.
