United Airlines’ cancellation policy depends on the type of ticket and when the cancellation is made. All customers can cancel their ticket within 24 hours of booking for a full refund if the ticket was purchased at least seven days before the flight. This applies to all ticket types, including Basic Economy. If United cancels a flight or changes it significantly, passengers are entitled to a full refund to their original payment method. Refunds are usually processed within seven business days for credit card payments and up to twenty business days for other payment types. For refundable tickets, passengers can cancel at any time before departure and get a full refund. For non-refundable tickets, canceling after the 24-hour window does not provide a cash refund, but the value of the ticket can be used for future travel after paying a change or cancellation fee. These fees can range from $0 to $400 depending on the route and fare class. Basic Economy tickets are generally non-refundable and non-changeable, except during the 24-hour window. In some special cases, such as death, military orders, or jury duty, United may offer refunds for non-refundable tickets if proper documents are provided. For award tickets booked with miles, passengers can cancel with no fee if done more than 31 days before the flight. If canceled within 30 days, a redeposit fee may apply unless the passenger has elite MileagePlus status. Changes and cancellations can be made online, on the app, or by contacting customer service. United recommends passengers check their ticket rules before canceling to avoid unexpected fees.
