They joy of flying Ryanair. If you understand the rules and how to work with them, you can get a cheap flight from A to B. Be on the wrong side of the rules, and suddenly your intended cheap trip becomes on the expensive side. Ryanair gambles on getting a fair number of the latter kind of passengers.
