Flight was delayed no information given really . No food whatsoever on the plane . I think you should be able to put that on the app so people have a chance to buy food bring it with them . They said plane was very busy on way over but there should be enough for both flights as we pay full price for the service. No information or very slow on the app about the delays . Staff were lovely it’s not their fault so company not fare to passengers or staff .

Smooth quiet flight take off and landing both excellent. Food was mediocre. Boarding at gate was disorganized and unacceptable.

My only complaint is that during my 8-hour-long flight, the flight attendants came around with the coffee and tea cart twice instead of the alcoholic beverage cart. I would rather sleep on a plane than rush to the bathroom to take a dump. I asked the flight attendant if I could have a beer instead of coffee or tea. Unfortunately, she said the bar is closed. That tells me that she was too lazy to get me a beer on the plane. I was not happy about that.

Caring & friendly crew. Most important: got us SAFELY to our destination!

Friendly flight attendants, decent food if you can eat dairy.

Very good trip. Nice clean aircraft. Helpful and friendly crew.

Other than Air Lingus not loading one piece of luggage on our flight from Dublin to Barcelona, with it arriving one day after we arrived in Barcelona, all was good.

Crew members Grainne and Karen were extremely rude and unprofessional

I am very disappointed in that KAYAK sold me this flight as a business class it was not a business class. It was a regular economy class ticket. This was not Art Linus mistake. It was kayaks.

Everything was great. I liked that one of the crew noticed my son's sunflower lanyard and asked them to let them know if we needed anything. That was lovely.

I didn't eat any food so can't comment on that. The prices on the plane are extortionate (as are all prices on planes). Everything else was seemless and a great experience

Guide passenger if fhey board from front or back door cause it was a total mess

I liked almost everything (e.g. ease of booking, price, punctuality, efficiency, friendliness, courtesy). A slam landing in Dublin airport took some of the gloss off it, though. Being able to paste here the text of the review of the same flight that I just wrote for Ryanair would make me feel better about Kayak too.

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.

Staff were very professional. Much better than the outgoing flight from Dublin. Seat cushions were practically non existent. Making for a very uncomfortable flight.

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.

They were extremely unprofessional and unhelpful at check in. They did not understand laws related to Spanish residents flying with family It was very discriminatory the way we were treated.

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.
