thanks JALpack. I ended up going for JL29. I don't care about lie-flat seat but 767 is older aircraft, monitor on skyluxe looks very tiny and seatings seems cramped (2-2-2 vs 2-1-2 for ANA or 2-3-2 on 777). Also going to Narita is a hassle just not my cup of tea (disclaimer i'm Japanese so i know my way around)
