As Dave writes, QF runs the upgrades in order of status CL, P1, P, G, S etc. So probably that if there were any upgrades they went to people with higher status. QF does not just ignore requests, also QF may decide even if seats are free to not offer an upgrade - such as catering, people cancelled too close to flight time, or just that QF feels that they should encourage people to pay. The plane type and route of course also plays into it. If you have a request we can look into it and provide a overal thought on what your chances might be. But most time sthey are gobbled up by platinums. The only silver lining to the QF upgrades is that paid (bids) come after FF requests.
