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.

Access to Lounge was not accessible in Madrid even though Aer Lingus Customer Support and Check in agent thought it should be. They could not figure out why the ticket was not scanning correctly in the lounge. In the end they blamed it on it being a 3rd party purchased ticket which makes me hesitant to buy from Kayak in the future.

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!

First leg of my flight: flight attendants - not very welcoming & also ran out of the snacks that should have been included on my flight. (I did not receive anything during flight because they said nothing was left - only things to pay for) Shouldn't they have had enough for all the people on the plane? Also, my seat, window and tray table were filthy - I had to clean it myself before sitting down. Second leg was better in terms of cleanliness - but honestly, both planes were really not clean (bathrooms included). The hot meal was pretty gross. But the canned wine was fantastic and felt elevated. No blankets, only pillows and plane was freezing cold. Pilots were great and landings were even better! As a frequent flyer... this was my first time flying with aer Lingus in many years and I have to say... I don't plan to fly with them again any time soon. I was overall disappointed.
