What is your QFF status.
With a bronze member, we call it NB, it will be very hard to get reward/award seats, if you have a lot of QFF points, but low QFF status.
As its a very high demand route, and a lot of people will want to have it up ahead on the plane, ...
Cash revenue fares will be sold first, then its CL/P1/WP/SG/PS, then NB, ...
Have a look at what the acronym means.
Having the points is one thing, ie, in your QFF account, and also seeing availability, but you putting in an upgrade/award request, is the main point, success relies on your QFF (ie higher status means success first).
Edit: ah, just saw you are not a QFF member, so you are going to start the ranking from down the bottom of the status ladder, so any chance of upgrades to premY/J/F will be low.
