The top off points are correctly withdrawn upon booking, as well as refunded upon cancellation (along with the Premier cert).
Thanks for doing that testing and reporting the results. I'm not sure I'd have the nerve to experiment to see if the points and cert came back. (Actually, I have a pretty good idea about whether I'd have the nerve, and I thank you again.)
