Are Longus was fine. I booked thru Kayak and was unable to get my business class seat early. Sat next to galley. Crew forgot to wake me for breakfast.

I was pleasantly surprised - it has been awhile since I traveled with them - other than being delayed leaving Malaga everything ran very smoothly- yes I would travel with aer Lingus again and yes I would recommended

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.

flight delayed, no information given until late on, Ryanair app said "on time" until 5 minutes before expected departure time, crew rushed us to board, when it was already 3 hours late

I got denied boarding bevause they said they "ran out of seats on a plane"

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.

What can you say Ryanair get you there,no frills Not so cheap anymore ..... but what is now days! Would use again as always. Good flight times for us.

Very unpleasant staff, disgusting service, ignoring requests, refusal to help

Late again rude staff at gate bullying passengers made us stand in the cold 3degrees for 40 mins before they let us board

The usual average Ryanair flight, but we landed 20 min before due time, which was very good.

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

I would have preferred something lighter for the second meal. Maybe a small sandwich .

They cancelled our flight the morning of departure at 4:30am.

We were told to check our bags at the last minute, and the communication was poor.

Lost our luggage in Heathrow. Showed up 3 days into a 7 day vacation. Very inconvenient and disappointing!!

My luggage never arrived to Zurich. They can't confirm when it will arrive

Late again. 3 out of 4 late. One cancelled flight and one lost bag.

Charged an extra 65 pounds for overweight suitcase, Not told how much overweight but had no choice but to pay the price. Compare to Delta Airlines where I flew internationally a few days before with this suitcase and no extra charge by Delta. Comfort was horrible. I am just under 6 feet tall, and good that the flight was only 1 1/2 hours, because my knees were in the seat back in front of me the whole flight. I felt that my knees were part way up to my chest. No reason to have the seats that close. I will say to the positive was the flight crew, very friendly and efficient.

The flight was delayed as they were waiting on catering. Catering. Was eventually delivered but they still had no food. No meals for us in business class - just a bag of nuts.

Our luggage is missing. We are at the Hotel Gran Via in Barcelona

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.
