United Airlines’ cancellation policy offers flexibility depending on the fare type. All customers can cancel a booking within 24 hours of purchase for a full refund, as long as the ticket was booked at least seven days before departure. This applies even to Basic Economy fares. After 24 hours, the cancellation rules vary. Basic Economy tickets are generally non-refundable and non-changeable beyond the risk-free period, though you may get a flight credit minus a fee ($49.50 one-way or $99 round trip for domestic; $99.50 one-way or $199 round trip for international). Non-refundable tickets can be canceled for a travel credit after deducting a cancellation fee—typically $200 for domestic and up to $400 for international flights. Refundable tickets can be canceled at any time before departure for a full refund to the original payment method, with no cancellation fee. Award tickets booked using MileagePlus miles can be canceled for free if done 61 days before departure; closer to the date, fees apply based on membership status. In special cases like death, military duty, or jury duty, United may waive fees or issue full refunds upon submission of documents. Flights can be canceled online through the “My Trips” section on the United website or app, or by contacting customer service. For third-party bookings, cancellation must be done through the travel agency. Refunds are usually processed within 7 business days for credit card payments and up to 20 days for other methods.
