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.

Well, I think we left close to on time. Crew was “eh”.

Seats are terribly cramped. I’m only 5’2” and my knees were practically in my face. No room to put a normal size bag under the seat and when the person in front of you reclined their seat your tray table was in your lap. This is the airline’s way of cramming more seats into the plane to make more money. I’ll think twice about taking Aer Lingus again since there are a few other options from Boston to the Emerald Isle.

The food was mediocre, the coffee was terrible. The entertaining selection was plentiful. They lost my checked luggage which put a damper on my 10-day vacation.

Weeeeeeell, you folks know economy class on Airbuses well--you're packed in like sardines. We may actually spring for more expensive seats next time, with a little room to stretch out. NO room to stretch out in Airbus economy class! :-) Apart from this, the food was decent (considering that it's mass-produced, and has severe spatial restrictions of its own), the staff were friendly enough, and there was a wide selection of movies, etc. to watch. Overall, I'd tend to use the word "adequate" rather than "exceptional" for my experience. But really, how could it be otherwise?

Food was very bad. Boarding was disorganized and messy. Crew was friendly

Gate agents kind of serious. Had to wait til arriving at gate to choose seats. Thankfully they did give us seats together! And grateful the honored our age, giving us seats at the front.

Great service on the plane and by ground staff. great prices. I was able to change seats on the plane. The allocated seats cannot be changed when checkin in online. They have to be done at the airport if you check in at the airport or on the plane by asking a stewardess / steward.

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

The transatlantic flight was wonderful. The regional reminded me of jet blue. Crazy and packed. Not enough overhead space and tough on elderly.
