Fast and sensible boarding was absolutely amazing. But extortionate wifi and seats that barely moved, making me unable to sleep, didn't do a lot of favors.

Fast and sensible boarding was absolutely amazing. But extortionate wifi and seats that barely moved, making me unable to sleep, didn't do a lot of favors.

No food service. A sandwich at this hour would have been good. My 1st time on AL so didn't look into pre board purchase options.

I liked the front row seats. A lot of leg room. The check-in window needs to be longer

A caveat, we flew during the ransomware attack that hacked the boarding and luggage tracking systems. I wouldn't ever be angry at the employees for that, but I WOULD be (and am) angry that communication was incredibly poor, that we got few live updates, and that the employees seemed uninformed and ill-equipped to handle the situation. Clear, honest, open communication and instructions would have benefited the situation. Unfortunately, there were literally no gate agents to talk to, no airport employees to direct people, and no clear signage (the app pretty much said "we don't know what gate your flight is."). Beyond this nightmare, the security was the usual dehumanizing circus of "Security Theater" which is... as we all know... only for show and completely useless. All three airports on this journey dropped the ball so hard. The flight industry can do so much better. Aer Lingus can do so much better.

My flights with Aer Lingus were very good and I will definitely fly with them. Again in future trips to Ireland and Scotland.

Too hot. Asked for an extra glass of water and was ignored. Asked to sit in empty seats that were open because it was so hot and crowded and was denied and the seats were empty the entire flight

Terrible leg room - I’m 5’3” and my knees were touching the seat in front of me. When the person sitting in front of me leaned back, there was about 15 inches of space between my head and the TV screen which made it awkward to view movies. Last year they had decent food, but this year the only tasty item on the trip was dessert.

The flight was delayed leaving Philadelphia due to “catering” and consequently arrived in Dublin some 75 minutes later than scheduled. Consequently this caused me to miss my connecting flight to Glasgow and I had to spend the night in Dublin.

The flight from Cincinnati to Philadelphia was satisfactory and uneventful.

It was truly a horrible flight. We were delayed almost 2 hours. The seats were so tiny, my legs were hurting the entire flight. When i finally made it to Ireland i missed my connecting flight because we left Newark late. I will most likely never fly Aer Lingus again
