I just called Qualiflyer:
They can only request an upgrade IF you already have a booking reference. They are unable to tell you in advance whether it will be available. This basically means you would be playing a risky game if you want to book non-refundable, you might just end up in economy after all ! </font>
If you can find out from Qualiflyer which class the upgrade is booked in, then it may be possible to ring Cathay direct and ask if they have any seats available in 'x' class for the flights you want to fly. If there is good availability - you might want to try. If there is nothing, or they suggest waitlist, I wouldn't risk it.
