Does anyone have a special way to trick the system (or the passengers) so that the seat next to you remains empty? Of course, if the plane is chock-a-block full, there will eventually be a body in every seat so no strategy will do any good. But what about those flights that don't fill up completely? For example, would selecting a middle seat in a set of three discourage people (or the system) from assigning the window or aisle seat? Would selecting an aisle seat in the last row in the cabin, particularly in the middle section of a wide-body, yield a higher probability that the center seat(s) will remain empty? (Since it seems that seats fill up from front to back...) What about a couple selecting both aisle seats in a center section? Does that work?
