Suppose someone applies Amex Platinum card and cancels it within 6 weeks to get annual fee refund. If this card is his/her only charge card, then chance is the points are not available to use yet, so what will happen to the points when the card is cancelled? In my experience, if you don't have Amex Reward account before, it will take a while for earned points to be available to use.
Anyone has experience to share?
