In terms of comfort, AA
's MRTC is the best... Both JL
have recently reduced seat pitch in Y from 34" to 32". Unless you are an elite member of United and have access to Economy Plus, I will avoid UA
regular Economy at best. Northwest's legroom is not too good either. So AA
seems to be the best choice comfort wise.
Service wise -- I like NH
better than JL
... But both Japanese airlines offer high quality meals, personal entertainment units, friendly F/As and offer many amenities, such as playing cards, stationary, postcards, and other stuff. AA
is not too bad... the meals look okay and you get bottled water on your first main meal service. Of course, F/As wise, the Japanese ones are nicer...
Entertainment -- UA
's Boeing 777s (one of the two flights) have PTVs, AA
, and NH
all have PTVs. UA
's Boeing 747 and NW
's flights don't have PTV. (of course when NW
's A330-200 arrived at the end of September, you will have PTVs, as SFO
), Japan">NRT is one of the first routes that these A330-200s will be in charge of...)
I hope this information will help...
