A true budget airline experience. Had issue with luggage tag needed customer service assistance, but there was only 1 agent open for the entire airport. ONE! Almost missed my flight because of that.

A true budget airline experience. Had issue with luggage tag needed customer service assistance, but there was only 1 agent open for the entire airport. ONE! Almost missed my flight because of that.

Always select priority to be able to take carry on luggage and board first without hassles.

Shady baggage policy that forces you to pay more money at the gate, even after you checked your bag dimensions during the bag drop. Will never fly again with this airline.

The plane had only a few passengers, we got lucky. The crew was visibly inexperienced

Buy-on-board through the app is a great feature!

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.

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

You have improved through the many years I have flown with you. But you still nickle and dime your customers. I paid extra for carry on and priority boarding.

While this flight from Dublin to Venice boarded on time, its departure was delayed by about an hour because, apparently, there were no demonstration kits on board, and we couldn't depart until the safety demonstration was completed. We were informed that we were in danger of losing our delayed slot if Ryanair engineering didn't provide the kits 'soon', which would have resulted in an additional two-hour delay. Thankfully, we didn't incur that additional delay. It's not clear where the source of this problem lies but it needs to be addressed to ensure it does not recur for other flights in the future.

Flight was delayed due to weather so not much Ryanair could do about that - otherwise it was very efficient and smooth
