United Airlines Check-in Information

United Airlines Check-in

United Airlines offers various convenient check-in options for passengers.

Here is a reiteration of the check-in options provided:

Online check-in (Web check-in)

Passengers can check-in online starting 24 hours before the scheduled departure time and ending 60 minutes before (depending on the departure city and destination). This allows passengers to receive a mobile boarding pass on their mobile device or a printable boarding pass. This option is available for passengers with an electronic ticket on United Airlines, and they can access their reservation using the confirmation code, e-ticket number, or frequent flyer account.

Mobile Check-in

Passengers can check-in for their flight using their mobile device starting 24 hours before the scheduled departure time and ending 60 minutes before (depending on the departure city and destination). This allows passengers to receive a mobile boarding pass on their mobile device. The requirements and eligibility criteria are similar to online check-in, and the departure airport should accept mobile boarding passes.

Curbside Check-in

At most U.S. airport locations, passengers can check-in for their flight curbside from 30 minutes to 4 hours before the scheduled departure time (depending on the departure city and destination). Passengers need to present their photo ID and flight reservation code, flight number, destination, or electronic ticket number for check-in. The exact list of participating airports and minimum check-in times can be found on the United Airlines website.

Self-service Kiosk Check-in

Passengers can check-in for their flight using self-service kiosks at the airport from 30 minutes to 3 hours before the scheduled departure time (depending on the departure city and destination). This allows passengers to receive a printed boarding pass.

Ticket Counter Check-in

Passengers can check-in for their flight at the airport ticket counter from 30 minutes to 3 hours before the scheduled departure time (depending on the departure city and destination). This allows passengers to receive a printed boarding pass.

Voice Check-in

Passengers within the U.S. or Canada with less than 10 people in their party can perform voice check-in over the phone by calling 1-800-864-8331. This option is available for those who don't have access to the internet or a mobile device. By using voice check-in, passengers can inform the number of bags they want to check, hear baggage service charges, and arrange for boarding documents to be delivered by email or picked up at an airport kiosk.

Auto Check-in

Eligible passengers have the option to select Auto Check-in for the remaining segment or a return flight when checking in for the first segment of their flight. When the remaining segment or return flight is within the 24-hour window, Auto Check-in will automatically check them in for the flight. Passengers can choose their preferred method of receiving the boarding pass, such as by email or mobile device.
