Unless you are a small child or flying for the first time, airplane flights are a drag. No one takes airplane rides for the fun of it. The whole business of going to the airport way ahead of departure time, going through security, and sitting in a cramped seat for hours, has eliminated any pleasure that the experience may have originally had, at least for me. You do it because you must.
Any person who has ever had their flight canceled at the last minute knows that it causes a real disruption in one’s plans, even if it was just a vacation trip. So it baffles me when people who had planned to travel by air do things that they must know will get them kicked off the plane.
