Demonstrate that the nation does not have a propensity to act like this at any given opportunity, then you can slag off the carrier, but I suspect you will struggle to show this is anything but loutish Brits being loutish Brits - it's what we are famous for.
Easyjet is one of the most professional airlines out there and beats many legacy carriers hands down in terms of service. They were just the unfortunate airline of choice for these social pariahs.
