On a recent trip, the flight attendant asked if I flew very often. When I said I did, he asked, “Have you noticed people on planes becoming increasingly more belligerent and aggressive in recent months?” I had to confess that I agreed with him. We began talking about what might be contributing to it—things like increased airport security, higher costs, fewer services, and a general dissatisfaction with travel. As if to prove the point, our conversation was interrupted by a passenger who refused to sit in his assigned seat because he liked someone else’s seat assignment better!
