The idiocy of the students barely warrants comment, really. But I will say this: have YOU ever tried to change your flight on a budget airline at the last minute and NOT incurred some hefty charges? Well, I wonder if the next time I want to get a later flight, all I have to do is board and then kick up a stink because I hear someone is talking in Hindu, or texting in Russian, or eating a foreign snack with their mouth open. I'm not sure where the line is for worrying behaviour with EasyJet, but it would be fun (by which I mean horribly depressing) to find out.
