i wouldn't say europeans love the Ryan Air concept,
it sucks! friends of mine had a lot of problems with Ryan air, bad weather, fog ? sorry your flight doesn't exist anymore, next flight, ok buy a new ticket, oh sorry next available seat ... next week, and not at a bargain price..
they fly remote airports, so only good choice if you have to be around the airports Ryan air flies,
they have a lot of one time customers, a lot never fly them again after their one time experience
