I just came off ba5 which is a one-a-day to tokyo. J was deserted, figure about 15-20% full (five upstairs including me). Talking to the crew, Y was pretty full, as was W. No idea on F but I did see a few coming off their bridge but maybe these were escapees from w as this I think was lowj rather than the usual hij plane. Also FYI, crew says it's full on friday when they fly back.
