Ryan requires you to check in at least 4 hours prior to flight. If you try checking in at the airport, you will be required to pat almost the full price of the ticket. I saw several passengers coughing up 68 Euros simply because they did not check in. We were a party of of 8, and 7 of us had checked in. The 8th passenger was asked to pay 68 Euro.
Other than that, the flight had no problem.
