I am booked CDG/BKK in October and used QCredits to upgrade J to F. Now I find that DOH/BKK/DOH is in a 77W in J. To be honest I would not have booked QR for this trip in J. As it is I'm going to have to accept it as there is a stiff cancellation penalty on the J fare. What are my chances of gettign some QCredits back - with an extension to their validity, as otherwise they are useless?
