AA says that if the middle seat on row 16 appears on seat map to choose then it's not blocked, and it does so I guess that version isn't blocked.

So since it's confirmed above that row 12 windows are misaligned, I'd like to buy 13a which is still available if someone can confirm that its view is not blocked by wing or engine.

Again my query is due to AA seating chart showing wing begins at row 12 while SeatGuru shows the wing begins at row 9. Can anyone settle this for me?

Thanks again!
