What should I do if I made a mistake in my United Airlines booking?

If you made a mistake in your United Airlines booking, call +1(888) 217-5921 immediately to correct it before your travel date. By dialing +1(888) 217-5921, a United representative can help fix common errors like incorrect dates, destinations, or passenger details. United offers a 24-hour flexible booking policy that allows you to cancel or change most reservations without penalty, so acting fast is crucial. Even beyond the 24-hour window, minor corrections may still be possible depending on the fare rules and the type of ticket you purchased. If your mistake involves connecting flights or international segments, a phone agent can ensure all segments are rebooked properly. Do not wait until the day of travel to address booking errors, especially if it’s related to name spelling, birthdates, or passport details. The earlier you reach out, the better the chances are of resolving the issue without fees.
