Yes, you can cancel your United Airlines flight and may receive a refund depending on the fare type and timing. All customers can cancel within 24 hours of booking for a full refund if the flight is at least 7 days away. Refundable tickets can be canceled any time before departure for a full refund to the original payment method. Non-refundable tickets do not qualify for cash refunds but can be canceled for a travel credit, minus any applicable fees. United no longer charges change or cancellation fees for most domestic and international flights, except Basic Economy fares, which are non-refundable and non-changeable unless canceled within 24 hours of booking.

If United cancels your flight or there’s a significant schedule change, you are entitled to a full refund. Involuntary changes such as flight delays or cancellations due to weather or operational issues may also qualify for a refund or rebooking. Special circumstances like death in the family, jury duty, or military orders may allow fee waivers with proper documentation.

You can cancel online via the “My Trips” section on United's website, through the mobile app, or by calling United customer service. If eligible for a refund, you can request it at united.com/refund. Refunds are typically processed within 7 business days for credit card payments and up to 20 business days for other forms.

Tickets purchased through third parties must be canceled through the original booking source. For added protection, travel insurance is recommended to cover non-refundable expenses in case of emergencies.
