飞机上争执:不要命的为什么越来越多?

　　Los Angeles Times says in 9 days there were three diversion of air flight caused by passenger fights over shrinking legroom.

　　The latest one occurred when Amy Fine wanted to nap on Delta flight 2370, from New York to Palm Beach, Fla., so she laid her head on the tray table.

　　The passenger in front of her wanted to relax with some knitting. She reclined her seat — smacking Fine's head and sparking an emotional explosion.

　　The resulting screaming match caused an unscheduled landing in Jacksonville.

　　The space squeeze — as airlines pack more people and profit into planes — is only the latest frustration for travelers, already weary of security hassles and charges for checked baggage, food, in-flight entertainment and other once-free services.
