Well, people with rollers in isn't exactly a problem is it? I'm not having a go - but you'd think from the way the media are reacting these people are trying to blow the plane up or something.
I get that people get a bit rowdy on an Ibiza flight - as diver said too, I reckon it's typical male behaviour. Maybe I'm too old and too much of an amateur psychologist, but I bet most of these lads would secretly admit they only behave like that because they feel they have to in order to "fit in".
In terms of the "booking early" thing - I don't deny that some people, somehow, still get cheap(ish) deals, but for the past three years flight prices have been the same 6 months before as they were the day I fly out.
