United Airlines Cancellation Fee Policy states that "flight tickets can be canceled within 24 hours of booking and you will not be charged a cancellation fee." If you make your reservation at least one week before the flight's departure, you won't be charged any cancellation fees.

If you cancel your ticket more than 24 hours before the scheduled departure time, you will be charged a cancellation fee. Please check our website for more information on our cancellation fee policy.
