Three in a week:

A flight from LaGuardia to Palm Beach International Airport was forced to make an unexpected landing after a heated argument over legroom. Delta Airlines Flight 2370 was officially diverted to Jacksonville "due to safety reasons in regard to a passenger issue" on Monday. But onboard witness Aaron Klipin provided a bit more context. The squabble, he said, stems from the moment the woman seated next to him tried to recline her seat ... "The flight attendant came over and that just exacerbated what was going on, and then she demanded that the flight land," Klipin said. The aggravated woman was cursing at the cabin crew and said something along with lines of "I don't care about the consequences, put this plane down now." Police escorted the angered passenger off the plane after it landed in Jacksonville.

Diverting planes is hugely expensive: it burns expensive jet fuel, it causes delays that cost airlines money, it can mean overtime for crew. So, hey, if the airlines keep having to divert planes because angry passengers are fighting about leg room... maybe the airlines will conclude that it's cheaper to give passengers a little more leg room? So keep fighting, airline passengers!
