More availability of water/drinks and less of a headwind

We arrived at airport around 9:30 AM and checked in by 10 am! Later we were informed that flight was 20 moms and later our flight being delayed by an hour and 10 mins. The arrival gates changed twice ! Plus traveling on the bus to and fro at both delayed further! This Placed an additional pressure on us in Dublin as we had to rush, run and clear both security and US customs. Where both sides were extremely busy with other flights to US. Luckily we boarded our LA flight just 5 mins before take off! No time for bathroom breaks or any shopping! Instead of relaxing flight it becomes more stressful due to timing and delays!

Incredible airline experience for many reasons. Only improvement, would be to have higher quality food, such as Organic and non-dairy food items. A number of us got sick. Thank you!

The legroom, seat width, inability to book my seat with the airline in advance when I paid extra to do so, the food is extremely plain and small. The cups of tea and coffee are small. Not to mention I had to pay for a g&T when I paid over $1k for a one way flight. Sheep travel better in a transporter.

It was a short flight, so not bad. No entertainment provided, nor a complimentary tea service.

Overall good. however, we were rerouted and my luggage was lost.

Ryanair delayed my flight by 7.30 hours gave us a embarrassing 4 euro voucher Got to Leeds/Bradford airport got to the car hire which I also booked through your site and they had given my car away then charged me a additional 192 pounds more for a car I didn’t even want complete scam

Aer Lingus App never showed the gate and the board did not update until very close to the time the gate was due to close. Both planes departed late but no announcement was made which would have saved a run for the gate.

Caring & friendly crew. Most important: got us SAFELY to our destination!

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.

They were extremely unprofessional and unhelpful at check in. They did not understand laws related to Spanish residents flying with family It was very discriminatory the way we were treated.

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.

Ryanair is always shite. Slowest boarding possible in the most uncomfortable way. It’s like they are are tad sadistic.

The boarding process was fast and easy , but the airport sign was not up on the board, so it was hard to know the correct gate , on the airplane there was NO Snacks and NO water …. Everything needs to be purchase …. It’s not worthy for the price we paid !
