overall very good; just found a bit poor the food options in Narita airport but the in the flight it was good but limited (no real choice to avoid seafood or clearly stay away from pork..); most of the food was tasty tho and the choice was nice, specially their snacks and dessert and drinks. The in-flight systems was so-so (too complicated interface; they should rehaul with a proper UIX), and I specially appreciated their segments of videos capsules about the behind the scenes including an overview of technicalities of their aircraft and days in the life of their pilots. It was refreshing and give a good ideas of the efforts and challenges every employees has to deal with. Loved it!
