It would be nice to know exactly what constitutes unruly, one example was given of violence but is violence a necessary component of unruliness for the airlines?
Unruly people are difficult to control and often do not obey rules:
an unruly class of adolescents
Unruly hair is difficult to keep tidy, often sticking up or out:
an unruly mop of black hair
does not inspire great confidence, I've had one incident where I got accused of being drunk because I was doing stretches waiting for the flight and they almost didn't let me on the plane. I guess if my respectable looking colleague hadn't explained to them I wasn't drunk and didn't drink I might have ended up categorized as unruly.
