EVA Air's cancellation policy varies by fare type and route. Generally, they offer a 24-hour cancellation window for tickets booked directly, allowing free cancellation within this period. Beyond 24 hours, cancellation fees may apply. Refundable tickets offer a full refund minus any fees, while non-refundable tickets may only refund taxes and surcharges. The specific terms depend on the ticket class (e.g., Economy, Premium Economy, Business) and fare conditions.
