3DS authentication is short for 3-Domain Secure. They are online security verification services launched by international card-issuers, namely Visa, MasterCard and American Express, which require the cardholders to supply both the credit card information and a personal security password to complete the authorization process, in order to prove that the transaction is made by the actual cardholders. If your card-issuer offers VISA SECURE, MasterCard ID Check™, American Express SafeKey® or JCB J/Secure™, our e-ticketing website will automatically take you to your card issuer’s website, where you will be required to enter your personal password.
If your card issuer does not offer such verification services, you will be required to present the credit card used in your ticketing transaction upon check-in at the airport for verification purposes, noting that the cardholder must be one of the travel companions.
If your credit card transaction has been successfully authorized through VISA SECURE or MasterCard ID Check™ or American Express SafeKey® or JCB J/Secure™, you will NOT be required to present the credit card upon check-in at the airport. In addition, the cardholder does NOT need to be one of the travel companions.(However, if you have only entered the 3- (or 4-) digit card verification code on the back (or front) of the credit card, then you will still be required to present your credit card at the airport.) For any abnormal credit card transaction upon purchasing, an email will be sent to the email address provided as notification of the transaction error. We have the right to request the passenger/credit card holder to present the credit card used upon purchasing or the passenger/credit card holder may be requested to pay the flight ticket in cash before taking the flight.
