Hi!

I think your decision is maybe no good.

Because ANA's Premium Economy seats are not good cost-performance.
Size of the seats are distinct from the Business class seats and are hardly different from the Economy seats.
Seat pitch and width are just wider about 20% than the Economy seats.

Besides all this,Premium Economy class is the same meal as the Economy class.

I prefer rumorded JAL's Premium Economy seats to the ANA's Premium Economy seats.I don't get on the JAL's Premium Economy seats.
They said JAL's Premium Economy seats looked like shell-flat...

enjoy and have a nice flight!
