I'm 0 for 0, but every international QF flight that I've been on has had multiple empty seats in F (including QF10/11 which is specially protected due to high demand). QF appears to prefer to fly empty in F rather than make the seats available for upgrade or award. I love this policy when flying QF but it really is very inefficient and should be reviewed. An empty seat in F on QF has negligible benefits for the other F passengers (it does not improve the experience or service). And I have yet to see the new wine list, I am thinking that it is only on paper and not actually stocked.
