Helpline united airlines cancellation

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.
