How to United airlines flight cancellation policy

United Airlines’ cancellation policy allows flexibility based on ticket type. For standard Economy and premium tickets, you can cancel within 24 hours of booking for a full refund, provided the booking was made at least 7 days before departure. Basic Economy tickets are generally non-refundable, but cancellations within the 24-hour window are permitted. For non-refundable tickets, cancellations incur a fee, with the remaining value issued as travel credit. Refundable tickets can be canceled anytime for a full refund. United also waives fees for changes or cancellations on most domestic and international flights for MileagePlus Premier members and other eligible fares.
