The best solution I have found in this situation is to place a folder or a couple of magazines vertically at the edge of my seat, right next to the armrest. I try to do this as non-confrontationally as is possible under the circumstances; I take out the folder or magazines, glance at the contents for a minute, and then place them beside me. This concedes the entire armrest to the other passenger, which is fine so long as I don't have his or her elbow in my chest for the duration of the flight.
