I'd like to make a note regarding this. You'd have a much better view when aproaching coastlines if you are in one of the first few rows over the wing. When you are on the first few rows behind the wing there is no aproach to be seen because of the wing obstructing a forward view. You would see the coastline only when you are exactly over it.

My recommendation. The first three rows or so. Or as far as possible to the rear.
