passenger incidents
 

No that's not accurate, well, there are certainly more cases in the US than Europe & the UK but sadly we still have plenty of cases here.

While a web search hasn't been particularly helpful there was a Jet2 flight from Manchester to Turkey which had to divert after a passenger started hitting others;

There was also a fairly well publicised incident with a big punch-up onboard a KLM flight from, oh god, Manchester again;

Those were just this year, there were also several incidents last year too though again I am having difficulty finding them (but they made news at the time). A few years back the amount of trouble with disruptive passengers on flights ex-LGW saw an airline successfully get the airport to shut down an airside pub, or so I was told by an instructor who granted didn't seem happy when I scoffed and said that when travelling PAX I'd be pissed off about not being able to have a pre-flight drink.

Sorry that I can't be more help.

My perspective is that in the US there is much more "don't tell me what to do" esp. in respect of masks and telling them they are required by law still provokes a very bad reaction.

In the UK we are willing to accept what authority tells us.

Just walked through Gatwick and whilst most airlines have abandoned masks, Emirates still have them noted as mandatory on board over all their check-ins.

id say the UK has caught up to the USA extremely fast in this instance. Even before the pandemic, some people on planes threw an absolute hissy fit when you tell them to put their seat belt on,
