The staff on the flight were utterly brilliant; there was a young man who was particularly exceptional. Boarding was quick and seamless, and service was great! Seats were fab, as was the entertainment and its ease of access

i’m The staff on my flight were amazing as always, beautiful professional staff, they do amazing job. the food ? room for improvement

The agents at the boarding desk were not very helpful, however the hostesses on board the flight were great, the food was ok, and there were lots for choices for entertainment. I was stuck in an middle row seat which was a pain on a full flight, but otherwise the flight was great.

The man in front of me reclined the entire flight, including during meals, which was aggravating. My screen had issues with brightness and kept flickering in and out.

Still some confusion about my baggage which was disconcerting. It was nice that there was extra space on the flight for comfort reasons. Staff very friendly

Everything was smooth and the meal was delicious. I really appreciated that Aer Lingus still offers complimentary beverages, food, luggage and headphones. It was nice that the main meal also featured some items typical to Ireland including the wheaten bread and Kerrygold butter. I generally found the flight a quite relaxing and enjoyable experience.

The seats are so close that you have 0 room to move. Not acceptable for an 11 hour flight.

Easy process you definitely need 3 hours to get on board from Fuminchino airport

Very quick flight, efficient boarding, and clear and thorough instructions and attention from staff.

Flight was ontime, clean, staff was friendly - there was turbulence but can’t avoid that (it’s a flight 😉)! The staff were attentive but would be nice if Aerlingus didn’t charge for coffee ☺️ but overall I enjoyed my flight experience and will travel with them again (Ireland’s Four star airline

I liked that the queuing was very quick and boarding was easy

Usual slick event. All the basics covered well. On time, plane full.

flight delay was announced after passengers were staged to board the flight. Communication regarding subsequent gate changes was poor.

Although our departure (DUB) was slightly delayed we reached our destination (LBA) ahead of schedule. The price was very competitive too (around €100 return). Plus, the departure times for both legs were very good: 13:05 and 15:10, respectively. I gave a neutral rating for Food and Entertainment because I didn't avail of either.

Just pushing back from gate now. Boarded into fourth aircraft with 13 hour delay to scheduled departure. Crappy experience.

Notified as to why there’s a delay with our flight.

Nothing unexpected considering it is a Ryanair flight. It does the job. Nothing above, at all.

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

Their customer service needs an overhaul. I wish we could access them and the could be more helpful. Also, the website has been crashing and I had numerous technical errors. My flight was cancelled and we spent so much time trying to get help because the tech was failing.

It is what you pay for. Always delayed. Very small planes. Hard to fly with kids.
