Always a window.
Not much photography can be done from an aisle seat.

The coast of France at dawn, the cruise ships of Miami, cloud formations, scars and gashes in the land of the Prairies and cities that spring up like an oasis, etc. Very unique photographic perspectives. Even the blurred lights of an airport terminal at touchdown can be an interesting picture if done right, although setting up a tripod in that tiny space can be tricky, but it has been done
