I called tonight and was told that they wouldn't do this until a week before check-in because they needed to guard against people cancelling and keeping the 'extra' points. Rather annoying given that the T&Cs for most reward bookings allow cancellation until 24 hours beforehand so their 'protection' doesn't really address the problem they say they are concerned about. Not very impressed after spending half an hour on the line only to be told I will have to call again!
