A: You can use them. However, please note the following precautions and use them accordingly.

• Due to the nature of the cards, the payment will be withdrawn from your account at the time the transaction is processed.
• If the reservation fails, the payment will be canceled immediately, but it may take about 75 days for the refund to be processed by the card company.
• Refunds due to cancellations may take a considerable amount of time regardless of the reason for cancellation (customer convenience, flight cancellations due to bad weather, etc.).
• The refund period varies depending on the policies of the credit card company you use. For details, please contact your credit card company.
