I loved how they arrange boarding (starting with people seated in back and moving to the front). Flight crew was very polite and welcoming. Seating was ok, I felt like there was enough leg space however it is noticeable when the passenger in front of you sets their seat back.

Flight staff very friendly and helpful where possible. Late flight and travelling with young child, cabin lights remained on for the duration of the flight which was a little disappointing considering the time of the flight. Overall very happy to travel with Aer Lingus.

Nice to be on a flight that wasn't fully booked so there were only two of us in the three seat row.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Delayed due to weather... fine. But then the board us. Rows 15 and back had to go down the stairs and back up the back stair entrance to the plane. No assistance offered. Then they inform us that we are delayed for paperwork for an hour. So why did we board? Then, about 45min later they inform us that it'll be another 60-90mins. Really? No wifi, no seat entertainment, no drink or snacks offered. And we were not allowed to deboard.

Great travel. Wonderful experience. Hope to do it again in the near future. God willing

Aer Lingus doesn't have plug ins for devices at each seat. They also did not give me a dairy free meal as requested and confirmed by staff. It was as if I had not requested anything. Otherwise, they were great!

There were a lot of empty rows. As a single passenger I should not have been seated with 2 others. The WiFi didn’t work. The Kosher meal was awful.

Both flights were delayed due to maintenance issues. Because they where late boarding all four of our bags where left behind on our last connecting flight.

Speakers were blaring. It's like being in a Moroccan market and you keep getting shouted at with what's for sale

We missed the flight due to very slow security control and lack of last call announcement. We only found out at the gate that the gate is closed. Altogether 14 or 15 people missed the flight FR4500 from Cologne to Dublin.

Everything went according to plan. Check in, boarding etc all were very efficient.

Flight with Ryanair more than 1,5 hours are awful... No space between seats, absolutely uncomfortable stay.

The flight boarded and departed Venice on time (more or less), the cabin crew were super friendly and efficient, the flight crew kept us informed of progress, and the flight arrived early in Dublin. All in all, this flight was as close to perfect as is possible to achieve. Well done, Ryanair. The fact that Ryanair aircraft arrive and depart from gates that are in the back of beyond in Dublin's Terminal 1 is a bummer - in terms of the length of the walk need on both ends of a return flight. But I suspect that this is not Ryanair's fault

Largas colas para el check-in, por seguridad, sin explicación, el equipaje de mano pequeño tuvo que pasar a bodega,

On time but no water , milk or refreshments of any kind on board. Which is poor, especially with children and elderly on board. Toilets filthy,

Boarding at Arrecife was commended way too early. Far too long for elderly to be kept standing on their feet. Otherwise we’ll done to all staff.

The boarding process was fast and easy , but the airport sign was not up on the board, so it was hard to know the correct gate , on the airplane there was NO Snacks and NO water …. Everything needs to be purchase …. It’s not worthy for the price we paid !

Booked through you used Kiwi who did not complete checking in until 24 hrs before departure when the check in was available 48 hrs before hence we sat separately. I will not be using you again.
