Brit and Canuck airlines have tended to be stricter, plus Southwest Airlines.
Recall a very rowdy pax died on SWA because too many people piled on him.
(Brit and Canuck airlines were using a ‘yellow card’ procedure - pin a yellow card to seat cushion to advice each other and pax that an individual has behaviour problems. AC pursued a court case against an abusive female and won, in part to publicize that there can be consequences.)
