Please do not credit the miles to QR, it is real pain in the neck to redeem awards. It seems like one has to go their office for any award ticketing or to recredit miles for cancelled awards. even when booking on their website one cannot pay the taxes and ticket the resv. one can only make a booking.
There are some people who have had success in getting the US office to ticket after you get a booking done by the Priveleges club, but on a few occassion when I called the US they said that all ticketing for awards resvs is done in the office ONLY. YMMV. There is lot of improvement needed for this program.
