Pros: Food - Free dinners even for economy class. Entertainment - Every seat has a TV that offers multiple languages and tons of blockbuster movies from a variety of genres. They also offer many television shows in multiple languages and genres and video games. Roomy- The seats are as non-roomy as any airplane. However, the flight attendants don't give you any trouble when you want to just get up and walk around and talk to people. It gives the plane a roomy atmosphere. You can go to spacier sections of the plane to hang out.

Pros: The crew was very professional and courteous; inflight meal was quite good and the prearrival snack of a tuna sandwich was one of the best I have ever had.

Cons: The flight had some occasional bumpy spots but that is not ANA's fault. The landing was kind of like a violent shock and the plane seemed to slide a little sideways but everything was fine.
