Perhaps it is possible to train cabin crew to do O'Leary's job too.

Should save a fortune.

Michael O'Leary is every PR person's nightmare! He will joke and say things like that all the time, which does get people to laugh (remember the beer and blow jobs statement?) but he often says things against advice.
Still, as long as he's seen as some sort of hero, he can get away with doing all of these things (unlike Gerald Ratner) and still have people queuing up at the door.
I may not fly with Ryanair anymore, but someone has undoubtedly taken my seat - although I do think that there are more people thinking like me every week.
I do wish I could find out what else he's up to 'behind-the-scenes'. We'll no doubt find out soon enough, there must be the opportunity to charge for something else soon. Maybe he will stop working to an average weight per passenger and begin weighing everyone before travel - to stop people wearing coats filled with stuff, or indeed overweight people as previously mentioned.
Actually, I'm surprised he hasn't started to offer reserved seating for a fee, like many other airlines. Maybe it's the cost of setting up the systems required, but that would be quite easy money and another way to extract money from families that would want to sit together, as against those travelling on their own or as a couple who could sit apart for an hour or two.
