Hi littleheaven
Your Airpoints account will continue. I have a credit card linked to mine so i will still earn Airpoints, and you can still use the Onesmart card as an airpoints card to swipe to collect airpoints, but the really good use of the onesmart for the US Itunes account is gone so i'm looking at a US Paypal to see if this will work.
i really don't want to go out and open a new credit card
