But the profile of our passengers is radically different to your average bucket-and-spade punter.
Charging for drinks is also not one of the problems we face. They are included in the ticket price, so there is no need to pre-load.
It's a common misconception that it's a lo-co or "bucket and spade" problem, but in reality the profile of passenger and type of airline are irrelevant when it comes to disruptive behaviour. Similarly, whether an airline charges for drinks or not is not a major contributing factor either. We started serving free drinks on long haul last year but it didn't have an effect on the rate of disruptive incidents, (not that it was a factor in deciding to serve free drinks).
Your rate is pretty typical by the way, most crew members of any given UK carrier will have dealt with a handful of incidents spread over several years. Some crew never see an incident.
