Yes, you can cancel United Airlines flights and get a refund, depending on the fare type and timing. United offers a full refund if you cancel within 24 hours of booking, as long as the flight is at least seven days away. This applies to all fare types, including Basic Economy. After that period, Basic Economy tickets are non-refundable unless United cancels or significantly changes your flight. Non-refundable tickets can be canceled, but you'll receive a travel credit rather than a cash refund. These credits are valid for one year from the original booking date and can be used toward future United flights. Refundable fares, which are typically more expensive, allow you to cancel at any time before departure and receive a full refund to your original payment method. If United cancels your flight or changes the schedule significantly, you are entitled to a full refund, even for non-refundable tickets. Award tickets can be canceled, and miles may be redeposited with or without a fee depending on your MileagePlus status and how close to departure you cancel. Refunds typically take 7–10 business days for credit cards and up to 20 days for other payment methods. You can cancel or request refunds online through your United account or by calling customer service. United may also offer refunds in special cases such as medical emergencies or jury duty, but documentation is usually required. Always check the specific fare rules when booking, as they determine whether you’re eligible for a refund or travel credit.
