The check in and boarding process was smooth, and the flight was fine.

The free WiFi was great so I could stream movies during the flight. I would like to have movies available instead of on my device. Thanks!

We had a wonderful experience with Aer Lingus. The seats were too close for the long trip. The crew was absolutely perfect. They were so caring and thoughtful! My husband did not have a good experience with Air Lingus on the phone when trying to take care of getting better seating because he is disabled and needed a wheelchair prior to the day of our flight! Mariam R. in Boston was so helpful with seating and getting help for my husband. Filip Pytka who works for OCS was extremely helpful! He made sure that we had the lift because my husband could not climb the stairs to get onto the airplane. He took us from the gate all the way down to where we needed to be.

We were an hour and a half late, which caused my rental car company to cancel my reservation. We had no car, had to take a taxi to our hotel, and then a taxi back to get a new car the next day. Sometimes lack of on-time performance can end up costing the passenger a lot of money, none of which is covered by the airline that operated the late flight.

Overall good experience. But seats were small and uncomfortable for the price. Good entertainment, staff friendly and attentive.

Smooth quiet flight take off and landing both excellent. Food was mediocre. Boarding at gate was disorganized and unacceptable.

Very good trip. Nice clean aircraft. Helpful and friendly crew.

Crew members Grainne and Karen were extremely rude and unprofessional

I am very disappointed in that KAYAK sold me this flight as a business class it was not a business class. It was a regular economy class ticket. This was not Art Linus mistake. It was kayaks.

Crew was friendly and seats were comfortable. The connection however there were no free snacks or drinks.
