You can cancel United Airlines flights and get a refund depending on the ticket type and when you cancel. United allows free cancellation within 24 hours of booking if the reservation was made at least seven days before the flight. In this case, you get a full refund to your original payment method. This applies to most ticket types booked directly with United. After 24 hours, the refund rules depend on the fare. Basic Economy tickets are usually non-refundable and cannot be changed. If you cancel after the 24-hour window, you will not get a refund for Basic Economy tickets. For other non-refundable tickets, you won’t get a cash refund but may receive travel credit to use for future United flights. Cancellation fees may apply depending on the ticket rules. Refundable tickets allow cancellation at any time before departure with a full refund to the original payment method. If United cancels your flight or changes it significantly, you are entitled to a full refund regardless of the ticket type. This includes long delays or major schedule changes. Refunds usually take about seven business days to process for credit card payments. To cancel and request a refund, you can use United’s website or contact customer service. It is important to check your ticket’s specific rules and cancel as early as possible to maximize your refund chances.
