I loved how they arrange boarding (starting with people seated in back and moving to the front). Flight crew was very polite and welcoming. Seating was ok, I felt like there was enough leg space however it is noticeable when the passenger in front of you sets their seat back.

I loved how they arrange boarding (starting with people seated in back and moving to the front). Flight crew was very polite and welcoming. Seating was ok, I felt like there was enough leg space however it is noticeable when the passenger in front of you sets their seat back.

Flight staff very friendly and helpful where possible. Late flight and travelling with young child, cabin lights remained on for the duration of the flight which was a little disappointing considering the time of the flight. Overall very happy to travel with Aer Lingus.

Nice to be on a flight that wasn't fully booked so there were only two of us in the three seat row.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Delayed due to weather... fine. But then the board us. Rows 15 and back had to go down the stairs and back up the back stair entrance to the plane. No assistance offered. Then they inform us that we are delayed for paperwork for an hour. So why did we board? Then, about 45min later they inform us that it'll be another 60-90mins. Really? No wifi, no seat entertainment, no drink or snacks offered. And we were not allowed to deboard.

Great travel. Wonderful experience. Hope to do it again in the near future. God willing

Aer Lingus doesn't have plug ins for devices at each seat. They also did not give me a dairy free meal as requested and confirmed by staff. It was as if I had not requested anything. Otherwise, they were great!

There were a lot of empty rows. As a single passenger I should not have been seated with 2 others. The WiFi didn’t work. The Kosher meal was awful.

Both flights were delayed due to maintenance issues. Because they where late boarding all four of our bags where left behind on our last connecting flight.

Aer Lingus interior is not the cleanest. I've seen crumbs on the seat and wrappers on the floor when I boarded
