It started bad at the gate. We were rushing due to the plane transfer. Then when we got to the gate, we stopped for coffee and then they made us throw away $50 worth of coffee. Very upsetting. Then my daughter’s bag never got put on the plane, so I had to spend another $600 on clothing for her in Prague. Needless to say, this is a failure.

Then my daughter’s bag never got put on the plane, so I had to spend another $600 on clothing for her in Prague. Needless to say, this is a failure.

There was a delay in my flight so we missed our connecting flight. Now were in dubmin for the night and getting home a day and half later

Boarding was extremely efficient; I appreciated the back-to-front loading strategy. The instructions from staff were very clear and thoughtful, and they were friendly and generous with service. In-flight entertainment was top-notch.

Everything is good, but my luggage was damaged. How are you guys gonna pay for my luggage?

Great service, comfy seats on a greater than 10 hr flight. On time. Really solid. Thanks Aer Lingus

More availability of water/drinks and less of a headwind

Amazing and I can’t wait to fly with them again

Besides having our original flight canceled and only having an hour between our connecting flights, the actual flight once we made it to our gate was a good one.

The overall sports experience wasn’t even OK. The fact I canceled when I was on my way to get food at the airport again this was a international flight. I was out of the country and I did have work the next day. It was very inconvenience and very last minute and it was very poorly communicated.

Seat was very uncomfortable. The worst in all of my travels. It sagged in the middle, worse than anything any airline can offer. Not flying aer lingus again.

Huge wait to board after waiting for 2.5 hours delayed flight

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
