With 64 J class seats it takes quite a while to do the meal service. You'll get a meal after takeoff and a full breakfast a few hours before landing so that eats up 4+ hours of the time. I usually watch a couple of movies and still have time for a good solid 8 hours of shuteye.

I take this flight regularly and find that sleeping as much as possible helps ease the adjustment to the new time zone. I have a harder time going westbound than eastbound.
