Boarding was smooth and seamless and the flight was without incident.

This was my first flight on Aer Lingus and it was great. The plane wasn't full so I could move to a seat with extra room. The food was pretty good for airline food and the staff was nice and attentive. I enjoyed the media provided during my 10 hour flight. We arrived home early and it's always good to be home!

Everything went as planned. The only issue I had was with the gate C31 attendant. The person could barely speak English and was very difficult to understand.

Delayed delayed. Poor professionalism. Our seats changed and we pay for them

The seat when "flat" was not flat and pad was too thin to cover it.

Seat bottom cushions are not good. I’m 165# & they hurt my butt. Plenty of legroom.

Left early arrived early..right amount of talking from pilots..of course had to love the biscuit and water!

The flight was delayed about an hour for a maintenance specialist to approve the maintenance repair

Better snacks but flight and crew were amazing on this flight

Good crew and flight was on time. It’s a small plane with limited overhead luggage space. They said the overhead space was full and I had to check my bag. There was still space when I got on. Waiting for my checked luggage added 30 minutes to my trip. Not the end of the world but also not great.
