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.

delayed flight stayed whole night at washington Dallas airport at seats , uncomfortable . i am senior citizen , very tired , worst travel.

Like getting a bus. No great luxury but will get you there

Got us to destination alive, albeit a bit late. Luggage was left behind. No live tracking app available (available on some other airlines). Supposedly going to be delivered in next couple of days.

Waiting area not big enough for all the passengers, no airport lounge.

Really appreciated the care, attention and friendliness of cabin crew. Very comfortable, prompt and efficient flight.

People were nice. Seats are so cramped my knees had to be pressed into the seat in front of me.

Dreadfully long wait for bags at Dublin coming off an already late flight.

Flight was delayed and there was boarding pass and flight information errors resulting in confusion and stress

Aer Lingus was the actual airline so they handled everything professionally.

Excellent service smooth flight f or the most part food was right now.I'm expectedly good.

The flight was delayed, and delayed some more. But there was more room on this plane than the one that flew oversees! There was no food or entertainment, but that’s ok, it’s a short flight

Was delayed for checks after evidence of bird strike, good call

The plane was delayed. That was only downside to flight. Crew was very nice
