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.
