Every seat was taken and it seems that all classes balanced out as they were not selling upgrades (or asking for downgrades).
Overall very mediocre experience. IFE and reading lights were not working for economy plus and first rows of go for 5 hours (they promised restarts but those never happened, took reboot of entire system). Plus got an explanation but go was pretty much ignored (even though row 23 had several EBD/EBG).
First food service was ok, but second was an inedible salad.
