EVA Air refund policy varies depending on the type of ticket and the time of cancellation. Here are some of the key points: For tickets purchased at EVA AIR's website or reservation/ticketing office, you can cancel your reservation within 24 hours of purchase and receive a full refund without penalty, as long as the ticket was purchased at least one week (168 hours) prior to the first flight departure. For tickets purchased more than one week (168 hours) prior to the first flight departure, you can cancel your reservation and receive a refund, but you may be subject to a cancellation fee. The amount of the cancellation fee will depend on the type of ticket and the time of cancellation.
