1 - QF is N1 in OW : private seat, great service, food and drinks
2 - CX is close second, too much centric on Chinese food for my taste,rest is great
3 - BA strangely comes third, mostly because of abysmal offerings from other OW airlines rather then by own merit. Occasionally great service and decent drinks, all the rest is sub-par. The service can also be terrible.
4 - QR have a very good wine list,all the rest is terrible.No PJ in F on day flights,very dated seats without any privacy and the crews are scared of certain type of passengers bullying them and annoying the rest of travelers.Sure, the jacuzzi in the middle of the toilet in F lounge makes up for this
5 - AA does not have F,period.Take 77W C and sleep trough the flight in a flat and private seat so you don't notice anything else.What they are trying to pass as F is a sad joke
I'm staying clear from the nuclear JL,so can't rate it
Also never been on JJ F but looks like a dying product anyway since it's being removed.
