Yep. Not once, not twice, but three times in the last seven days, a domestic flight has been diverted as a result of an onboard argument between a seat recliner and a legroom lover.
This time, lucky passengers on a Delta Airlines flight from New York City to Palm Beach, Florida got to spend part of their Labor Day holiday in Jacksonville after an altercation broke out early in the flight and the pilot was forced "stop the car until you kids stop fighting!" -- or something like that. It was the airline's second diversion caused by a legroom issue.
According to Aaron Kiplin, an unfortunate passenger caught in the middle of the mess, a woman who was knitting reclined her seat without noticing the woman behind her sleeping head down on the tray table (how is this comfortable?!).
