China Airlines cancellation policy depends on the type of ticket you have purchased and the circumstances surrounding your cancellation. If you have a refundable ticket, you can cancel your flight and get a full refund, minus any applicable cancellation fees. The exact amount of the China Airlines cancellation fee will depend on the type of ticket you have purchased and the fare rules associated with it. If you have a non-refundable ticket, you will not be eligible for a refund. Contact China Airlines Customer Service for more details.
