I had heard horror stories about Ryan air and was a little worried about my flights with them but I had 3 flights with them in Italy, Puglia and Sicily and it was a painless and smooth process. I was very happy.

I had heard horror stories about Ryan air and was a little worried about my flights with them but I had 3 flights with them in Italy, Puglia and Sicily and it was a painless and smooth process. I was very happy.

Flight was delayed by 1 hour 45 minutes. Aircraft was cramped, dirty and uncomfortable. Boarding staff more interested in charging you for oversize baggage than getting you on board. Overall not a pleasant experience.

From boarding to disembarking, the whole operation was very efficient.

I didn't know that all connecting flights require online check-in two hours in advance, so I was fined 55 euros. This is a lesson learned.

A delay of almost 3 hours. It was evident that the staff wanted us to board urgently, to the point of rudeness, to avoid paying compensation

There isn’t any entertainment. The food and drink was available for a price. I didn’t buy any.

It would be nice to have power to charge phone.

They boarded us but somehow did not manage to record us boarding, so rather than check if we were onboard they removed our bags from the aircraft. I got a call from Ryanair staff in Dublin when I landed in Madiera asking me where I was!!! When I said I was in Madiera I was told what had happened. Our bags were to be sent to Madiera the next day via Manchester, they didn’t arrive. They are now due to arrive two days before we leave. I don’t see myself using Ryanair again unless I am forced to and even then I may just refuse.

Flight was fine, crew were good, cabin director spoke far too much; disembarking at Dublin Airport and entry into the terminal building was just dreadful, like entering the back door of a neglected factory building. What an awful impression it must give to first time visitors to Ireland.

Flight was over an hour late. Boarding was really messy with long queues at the plane.
