Doesn't charge you for a tea or coffee, isn't decorated in vision destroying orange or with ads on the luggage bin lids, doesn't play a fanfare and a loud announcement about 'another Ryanair on-time arrival' as the plane taxis in, doesn't describe an airport two hours drive from Frankfurt as a Frankfurt airport, doesn't tell you your bags have been offloaded then you see them appear out of the plane 10 minutes later - and the next morning when you are on the flight hold it for over 30 minutes become some passengers have been delayed (ie - consistency). I'd rather travel on a London Transport bus!
