I'm an additional cardholder on an account; what happens if the primary cardholder closes their account?

When a primary cardholder closes their Flybuys account, as an additional cardholder, you will also lose access to the account and any existing points, offers, Flybuys Dollars and rewards will be removed. 

You can open a new account here but will not retain any points, offers, Flybuys Dollars and rewards from the old account.
