Online check-in help and FAQs

Online check-in lets you check in from your home or office and print your own boarding pass. You can also choose to have a link to your boarding pass emailed to your mobile device. Just display your boarding pass barcode on the screen of your device at the security checkpoint and when boarding your flight, and you're on your way.

You can also use the United app to access your boarding pass for over 30 different partner airlines — you just need to be connecting from a United flight to a flight on one of the participating airlines. Learn more about the United app

Check-in is available starting 24 hours before your scheduled departure. Required timing for check-in, baggage check and boarding may vary based on your departure airport and destination. See our Check-in and Airport Processing Times page for details.

If seats are needed on your flight, you may be asked if you'd like to be added to the volunteer list during check-in. To learn more, you can visit on our Volunteering Your Seat  page.
