Asiana Airlines cancellation policy allows passengers to request a refund or make changes to their itinerary depending on the fare type and the time of cancellation. For refundable tickets, customers can typically receive a full or partial refund, while non-refundable tickets may be subject to penalties or fees. The amount refunded also depends on the timing of the cancellation, with earlier cancellations generally resulting in a higher refund. Asiana Airlines may also offer the option to reschedule the flight within a specific time frame without incurring additional charges. It is recommended for passengers to review the specific terms and conditions of their ticket and contact Asiana Airlines directly for further assistance regarding cancellations and refunds.
