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 do either of 2 things:
Navigate to the 'My Bookings' page and in the booking overview, scroll down and click the orange '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.
In both cases you do not have to wait until the due date. You can pay the remaining amount whenever you wish.
