According to IATA Resolution 890, in case CVA is debited by the credit card acquirer for a fraud case, a purchase rejection by the passenger, or a credit card misuse on a ticket issued by the agent, CVA will charge the agent for the cost through an ADM. The travel agent is responsible for checking the validity of the credit card, to ensure the cardholder’s signature is provided, and to ensure that the credit card is accepted for payment by CVA.
