Even if your ANA Mileage Club number changes, your registration on Travel CUBE is not automatically updated. Until you complete the update, you will be unable to log in using either your old or new ANA number.
Please log in using your Travel CUBE ID (registered email address) instead. Once logged in, go to "My Page" > "Member Information" to update your account with the new number.
Please refer to the FAQ below for information on how to update.
