Upper deck was nice as is mentioned in prior two posts. Tiny coach cabin relative to the size of the plane (you can go down the staircase to see the main cabin if you want).

If you want row 81 or 91 (which are comparable to NWA A330 row 10 in exit-row unlimited legroom), you'll have to pay USD50 extra.

It was really funny to watch the FAs line-up before getting on the plane at JFK - it's a huge group!
