Baggage handling was poor. Baggage was delayed. Communicating updates on finding and delivering the baggage was poor.

I love flying with them, the long-haul was fantastic. The short flight from Dublin --> Switzerland was horrible though. Most narrow seats I ever had, first and only time in my life I couldn't even close the seatbelt in seat 1A which was very embarrassing so I had to sit in the middle, because that seatbeld was 20cm longer. No idea why seat 1A would have a much shorter belt, it's just ridicilous. Also I hate the fixed seats, way too narrow.

It was poor overall. They cancelled our flight and changed it without notifying us. So we incurred extra costs by having to book a hotel for our layover. They say it's Kayak/Underpricer's responsibility to reimburse us. But Kayak/Underpricer have said it's Aer Lingus' responsibility because they are the ones with our 'booking information.' I find this situation confusing and unacceptable.

Staff was generally friendly and helpful. Attendants collecting trash were somewhat inattentive though.

It was my first transatlantic flight with Aer Lingus. Very enjoyable. Thank you for making international travel enjoyable again.

Everything went well. I made my connection which is always a concern.

The flight was delayed by about an hour, but the staff and signs at the airport never actually said it was delayed. At the expected boarding time, we were told we would be boarding in about 10 minutes, then 20 minutes passed, and were told again that we would board in about 10 minutes. That happened multiple times, such that "10 minutes" turned into an hour.

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.

Staff are so nice and friendly, plane was very clean and plenty of leg room

It has nothing to do with Aer Lingus and everything to do with Frankfurt airport. There eere no visual displays of the flight destination at the gate. They kept changing our gate with semi audible public announcements and eventually I was at the wrong gate and my flight departed from the other gate.

Had no disruptions or delays. Did not order any food.

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.

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

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

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

Flight was fine, crew were good, cabin director spoke far too much; disembarking at Dublin Airport and entry into the terminal building was just dreadful, like entering the back door of a neglected factory building. What an awful impression it must give to first time visitors to Ireland.

Worst experience ever. First time and last time with Ryanair. I'm not a cow.

Didn’t like anything about it we were delayed by 3 hours and sat on the plane when leaving Dublin. On the way back to Dublin we were kept in the plane on tarmac for 4.5 hours. This airline is a joke!

Delayed flight. Received notice from ryanair by email and via app but no such timely information available at airport from monitors or staff

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.

Very comfortable plane. The food was very good (for airplane food). The crew was great

I liked the flight, the attendants, and the comfort. But the gate for boarding was poor. Even the elderly had to climb down many many steps to the bus and climb up to the plane.

There was no entertainment or food service (short flight). The flight was delayed more than an hour.

It was a very smooth and on time flight experience. The crew was really friendly and polite. We were well informed about the flight, etc.

Cancelled 90 min AFTER Departure! We had to deplane and wait another hour plus for the flight to be shown as cancelled for the customer service team. There were many many angry customers.

Good and they are leaving at time and arriving on time

Horrible airport ever. We stood in the security check line for more than an hour. It was past boarding time and we were still waiting in line for the security check. With 2 children and a medically ill person we had a very stressful transit.

Overall excellent service and Frankfurt Airport was very efficient and clean

Terrible experience. I was stuck in Germany for two full day because your flights can't leave on time. You guys suck!!!

Didn't have bar code on our phone based boarding pass. People at the counter didn't notice. We walked to security, couldn't get through, had to go back to check in to get a paper boarding pass.
