All very good The food definitely lacks quality and at breakfast I was given a small muffin small orange juice and not even a coffee or tea were offered It would have been nice to have that first thing Apart from the food everything else was excellent

It was mixed. Some of the staff were wonderful, some a little surly. I also had some issues with my flights, and when asking for answers and clarity, no one seemed to really know things that really should be part of the knowledge available. My baggage ended up being "lost" or delayed, there just seemed to be a lot of confusion. The flights themselves were comfortable overall.

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.

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?

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.

Excellent as far as the flight is concerned. Faro airport passport check was a huge delay and worrisome re missing the flight. 45 minutes there through passport control

Excellent service, full flight but all went well ; slightly delayed start at Faro but arrived in Cork on time.

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.

There isn’t any entertainment. The food and drink was available for a price. I didn’t buy any.

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.

Everything was OK but I got the feeling that the aisle seat in row 3 is smaller than the other 2 seats

Good flight. Take off a little late but make up the time

O voo atrasou um bom bocado A tripulação não era comunicativa,não fez vendas... Não abordava os passageiros... A 1°vez que me acontece tal coisa 🤷‍♀️

Bag check in was terrible. Arrived 2 hours and 10 minutes ahead of required time and then waited 50 minutes in line to check ONE bag. There were 4 employees standing around as only two were checking bags and there were 6 gates available to check bags. Process is terrible. Lack of customer concern and service.
