Also, you can sort of combine qmiles and qcredits: by simply making several requests for different sectors/passengers.

As for how to go about that: I suggest you call the Privilege Club hotline BEFORE you book. If you're flexible, you can ask them about upgrade availability for different dates/flights. Once you have a flight with availability, you book it and then call back immediately for them to upgrade you.
While I haven't tried it that way myself, I heard this works and it seems the most secure to me.
Otherwise, you can also check for award seat availability, that USUALLY corresponds quite well with upgrade availability. but not always.

Either way, good luck
