Allow reservations to be canceled for a certain period after purchase
When you book and ticket a reservation through United Reservations, united.com, at our ticket counters or city ticket offices, or if you use MileagePlus® miles to book an award ticket on United, we will allow you to cancel the ticketed reservation without penalty and receive a 100 percent refund if you cancel the reservation within 24 hours of purchase and if the reservation is made one week or more prior to scheduled flight departure.
