Which A321 coach window seats can't see the wings or engines?
(i.e. unobstructed view of the ground and sky)

I sat in 6A last week and when I looked out, I kept seeing the
engines. (not that it was a bad thing, because planes do need
engines to fly, AFAIK) I just want to get a window seat
on the return flight with good views. It's a 3.5-hour flight.

Thanks!
