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.

Take off was great but landing is always with a bump.

Ryan air flight was good. Nothing to complain about. I had heard absolute horror stories about Ryan air so was worried about the flight but everything went smoothly. We have had two Ryan air flights with no problems. Last flight is Vernon come. Palermo to Milan. Fingers crossed.

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.

What we can expect? Soon we will have to travel standing on the hallway. Let me be fair, I had worse experiences with Ryanair.

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

It's not the staff's fault. The cabin crew do their best but the setup in Stansted Airport by Ryanair is poor. The herding of people like cattle is unacceptable before boarding and is something that's in every airport but only in Stansted have I seen the queueing of passengers outside the plane on the tarmac and the crew only turning up with maybe 5 minutes to depart. This is a resource issue . Yes prices are good but seemingly comes with a price of poor treatment of customers. I'll pay more next time

On time arrival but the aircraft had seen better days and needed a deep clean.

It was appalling, full of young people who were drunk and disobeying instructions to sit down. Crew did nothing to enforce. There was a Ryanair pilot sitting in the aisle opposite me who talked through out the safety briefing so loudly I couldn’t hear. Whole thing felt unsafe

The check in process is chaotic. It says partially checked-in. Never heard of such a thing. Then lost our reserved seats when we finally checked in at the airport. The seats don’t recline. Then we had to get mew boarding passes at the connection. Last, my companion lost her baggage and up to now there’s no update. We’re already half-way through our vacation and still no news what happened to the luggage.

Wonderful! Everyone very helpful and kind. Returning flight was cancelled but rebooking was easy.

Pretty normal flight was delayed due to traffic could have missed connecting flight to Venice but crew kept us well informed so we made it

Flight was on time and pretty standard. No Hiccups. I have no complaints, which is a lot to say about a 12 hour flight.

-The seats could be roomier -The entertainment in English could be more current! The moves were very old!!! -They served too many carbs! What happened to fruit and yogurt!!!!

We upgraded to premium economy and it made a difference in a 12 hr flight. I didn’t like that we had to deplane in the tarmac with our carryon luggage. Other than that, it was ok.

Everything was much better than I had expected, since I hadn’t heard of your airline before. I hope to take advantage of your excellent service again.

Staff were nice, we left on time and arrived early, food was good. Unfortunately, they lost one of our bags and have been unable to find it. So we are in Italy for a week for my husband‘s birthday and he does not have any of his clothing.

They gave us sandwiches as a meal twice. Snacks mid flight with cookies and a tuna panini. Then just the same tuna panini for dinner. That was it.

Top notch re cleanliness, comfort, operational. Attendants attentive, cheerful, courteous and professional. An unusually high-grade experience all around.
