Please check the following and use a different credit card or contact the credit card company.
- Please enter the card number, expiration date, cardholder name, and security code the way they are shown on your credit card, including the use of uppercase and lowercase letters.
- If your credit card is locked because the limit has been reached or it has been used continuously or the 3D Secure (security standard for online credit card payments) registration and authentication cannot be confirmed, an error may occur when you try to make a credit card payment, and your credit card is checked.
*Caution*
When you booked and purchased a flight on an air ticket comparison website instead of AirJapan’s official website or at a travel agency, you may not be able to add optional services on the booking confirmation website. （[Note] About the purchase of air tickets on air ticket comparison websites）
Please contact the booking website or travel agency where you purchased your ticket. We apologize for the inconvenience.
