To be an "unruly" passenger these days likely means one of three things: exhibiting violent or dangerous behavior that could pose a security risk; engaging in confrontational behavior with the flight crew that might escalate throughout the trip; or, unwittingly signaling to the flight crew that a problem could develop en route.
Hours too late for some passengers, MSNBC has attempted to make clear two of the three ways you could be considered "unruly" the next time you fly, but what is that third way they're talking about? I unwittingly signal to everyone that a problem could develop anywhere all day long. I guess double the Valium next time? Or wait, does that qualify as the firsts type of "unruly?" Oh, forget it. Just get a boat.
