Short answer: no we cannot update your credit card info as we do not store it. Our Payment Service Provider Adyen.com stores it.
If the remaining amount is scheduled to be automatically deducted from an expired credit card, you can choose from either of these options:
Navigate to the 'My Bookings' page and in the booking overview, scroll down and click the yellow 'Pay' button, and pay with your new card.
Click the payment link in any of the booking related emails we sent you, and pay with your new card.
Wait until the auto deduction of the remaining payment amount fails, and pay with your new card by clicking the payment link in the notification email we send.
Please note, you do not have to wait until the final due date. You can pay the remaining amount whenever you wish.
