btw, looks like this link shows the seats available
for sale in each class (not award)
not sure how accurate the info, and it shows enough granular detail:
1-9, O(available), M (few), X/- (none)
probably useful enough to guess possibility of F opening up close-in (8 F on 777-300ER)
someone want to compare it with EF (unless EF is scraping the same data?)
