I've used Ryanair a few times, most recently to fly from Valladolid to London Stansted Airport. It wasn't the unpleasant experience I was expecting it to be. But I did dislike the company's lies: for example, a one-hour flight will be advertising as leaving at 1 and arriving at 3, so it can run an hour late without a problem. You arrive at 2:45, and they proudly announce "another on-time Ryanir flight". That's why the company claims that it's the most punctual airline in Europe ... the other thing is that they claim to lose the least luggage, but really that's because nobody checks it in because it's so expensive! Well, apart from that, I can't really complain - for 30 euros you can go almost anywhere in Europe, and there are incredible 1c ticket offers sometimes.
