My wife and I often book an aisle-window combination in rows that are 3 seats across. If we luck out, the middle stays empty and we enjoy a bit of extra room. If the middle is occupied then sometimes we offer our middle seat neighbor a swap to the window-- but at least half the time we stay in our aisle/window arrangement. Some people wonder, "How could you not sit together?" The answer is that we're together plenty already; we can manage a few hours slightly separated. Plus, we tend to use our time on the flight as quiet time anyway. When we do talk, we're considerate not to bother the middle seat passenger too much. ...Not to imply that doing otherwise would justify the sort of behavior seen in the video above.
