I once sat next to a six-foot-plus professional hockey player. He wasn't particularly comfortable in his coach seat, but he fit. I still had my seat all to myself. So the problem isn't about people being taller; we haven't gotten that much taller in 50 years of commercial flight. The problem is about people being obese. Americans have become much heavier and wider in the last 50 years. But for 99 percent of obese and overweight people, the extra weight is something they chose by their actions. I do not believe that the airlines should accommodate those choices by making all the seats larger, which would increase costs for all of us. I don't need six more inches of seat, so I don't want to pay for it.
