The airline knows that you may need to cancel your trip unexpectedly, and thus it offers a flexible booking policy for the convenience of its passengers. The policy gives freedom to all travelers to make changes, including cancellations to their existing bookings within 24 hours of ticketing without paying any fee. To avail of this benefit, make sure that you have made a reservation at least seven days or more prior to the scheduled flight. If you are completing your United Airlines cancellation within this time limit then you are eligible for a full refund.
