When I was in college I was on a red eye flight from the west to east coast, seated in an aisle seat near the back of the plane. I’m on the shorter side, and a rather tall gentleman in the same row who had the window seat asked if I wanted to trade. Worked out well - he got a little extra leg space and I was able to sleep with my head on the wall without being disturbed by someone wanting to get up to use the restroom.
