Cathay Pacific’s cancellation policy varies by ticket type. For fully refundable tickets, you can cancel your flight without a fee. Non-refundable tickets may have penalties. The 24-hour cancellation rule allows you to cancel within 24 hours of booking for a full refund. However, changes to your booking may incur charges based on fare type and timing. Review the fare rules in your booking or get in touch with Cathay Pacific’s support team for further clarification on how to cancel your flight effectively.
