I think drunken behaviour on budget flights has nothing at all to do with "poorer" passengers. Budget airlines are increasingly the choice for hen and stag groups who want to spend maximum time drinking and "having fun" with total disregard to the well-being of other people on board the aircraft. The groups are often three sheets to the wind before they even get on the plane and just get louder and more raucous as time goes on. They're just as likely to be on good incomes but they want to spend as little as possible on their tickets so that they have more cash for alcohol.I also agree. It’s the automatic linking of the increase in that behaviour to the affordability of flights (and hence the increasing number of “poorer” passengers) that I can’t get on board with (no pun intended!).
For the record, I'd never fly Ryanair either. I'm not anti-Irish, I'm anti-bad service. I work in the travel industry so not basing this just on personal experience.
