Dinner was fabulous. Would have enjoyed a wine with it. None offered... for sale??? Breakfast was disappointing but adequate amount of food.

Dublin airport is big and US Customs and Immigration screening officers are is part of the process there. This eliminates screening upon arrival to US, however should be taken into consideration when playing your transfer. After all, pleasant experience enhanced by draft Guinness and Irish coffee at the buffet area near the gate. We loved boarding by the row, back of the airplane first.

There was a mixup with our tickets. They said they did not receive payment for them but yet we had seat assignments. We had to purchase last-minute tickets which cost us three times as much. that’s why they got a rated of a one.

I was pleasantly surprised and enjoyed the services of the airline since flying is not my favorite thing. My goal was to be with my brother's family in Manchester after his death. All staff was helpful, the food appreciated since I selected an overnight flight. Every aspect of the experience was comforting. I plan to return to Manchester in order to attend my brother's funeral in October and hope that I am able to find a reasonable priced flight. Thank you

Terrible. So upset either way this flight. We scrambled to make it as it was delayed an hour.

The worst Terrible Late for connecting flights. Made flight without luggage! I am still waiting for my luggage to be returned! I paid premium for this flight. My luggage should have been flown to Hartford instead they keep telling me it was put on a jet blue flight and is in New York! I flew Hartford to avoid New Yofk! The flight over was also unpleasant. We were stuck in a bus at Edinburgh airport for 30 minutes then our luggage again could not be found! Very poor service. Very disappointed . I need my luggage to be returned. Shirley Baliki 42 Blaine Sreet Fairfield CT

We were very satisfied and would fly with Aer Lingus again in the future.

Baggage fees are deceptive! When I booked this flight, I purchased two tickets and had indicated that I wanted one checked bag. That increased the ticket price by about $100 PER TICKET!. When we went to check in, I was told that I could only check ONE bag, even though I had purchased TWO tickets. I had to pay an additional $50 each way for my wife’s bag. In my opinion, I paid twice for her bag.

Better food than other airlines and the flight staff was very attentive and nice.

Delays resulting in missed connecting flight. Attendant failed to arrange special assistance as promised to get us on connecting flight. Robyn was the particular attendant.
