Ryanair is a hack of an airline.
I personally was returning from the domincan repulic on one of their charter flights a couple years back.
They said their was a fuel shortage on the island and we wouldn't be able to get enough fuel to go to our scheduled stop, and would have to go through Miami. So we made a landing in MIA and they were totally unprepared for our arrival there. We had to wait two hours on the tarmac for gate space and then had to endure the 3 hour sojourn in customs due to our unexpected arrival.
During this whole ordeal the crew of the plane did not disembark, but remained on-board. By the time we had returned they said they could not take us to our destination because of a federal law that limits the amount of time crew can remain on an airliner. They left us in Miami. No representative, no lodging, or connecting flights. We were trapped there for 36 hours before the travel agency managed to get a rep.down to us and organize our flights back.
Neither ryan-air nor the travel agency agreed to take responsibility for the new tickets and we had to pay our own way.
This was all later resolved in a class action lawsuit, but when the rep told the angry assembled crowd that we had to pay I thought they were gonna tear him to shreds
