There are threads on similar themes running around the forum, often from the CC point of view.
I can't help but think at times that the whole air travel experience is setting them up to be the target of SLF's frustrations.
Lets face it, you travel to the airport, endure (at times) queues for check in, queues for security, hang around in an expensive "warehouse" and then queue to actually get on the a/c.
At all these stages there is little time to "rebel" 'cos all you want to do is get to your destination. And anyway with the use of agents contractors etc. there's little point!
So the first opportunity is when your in the aluminium tube with a "captive" crew who are there "to cater to your demands".
It's IMO seems a bit like the road rage scenario.
It would be interesting to see if the incidence of poor passenger behavior has increased since the increase in security & the decrease of the concept of customer service prior to boarding.
Note that is not to say that any individuals are giving lower levels of service just that the companies involved are not providing adequate resources!
Coupled with that is the lack of consequence attitudes seen around the country where unruly behaviour is allowed and publicly seen to happen, with luittle or no consequence.
