24-hour flexible booking policy

We’ve permanently gotten rid of change fees for most Economy and premium cabin tickets for travel within the U.S., or between the U.S. and Mexico or the Caribbean. There also won't be change fees for other international travel originating in the U.S.

For all other standard Economy and premium cabin tickets, change fees are waived through September 30, 2021. Basic Economy tickets can be changed if they’re issued by December 31, 2021, for travel commencing by December 31, 2021.

We know that life happens, and you may need to change your travel plans unexpectedly. United's 24-hour flexible booking policy gives you the freedom to make changes to select reservations within 24 hours of booking and ticketing, without being charged change fees if you made your purchase one week or more before the flight was scheduled to depart. This includes canceling your reservation and requesting a full refund of the ticket price. Although Basic Economy reservations aren’t eligible for changes within 24 hours, they’re still eligible for a full refund if you cancel within 24 hours and you made your purchase one week or more before the flight was scheduled to depart. Please view the terms and conditions below for more details.
