You are required to present the credit card used to purchase the ticket during check-in at the airport. If you will not be among the travel party, you must go to any EVA Air office and sign an Indemnity of Payment form during business hours and at least 48 hours before the passenger's scheduled departure. Passengers who fail to do so will be denied boarding unless they purchase a full-fare ticket. I agree to the above terms and conditions for using a credit card.
