Fast and sensible boarding was absolutely amazing. But extortionate wifi and seats that barely moved, making me unable to sleep, didn't do a lot of favors.

Fast and sensible boarding was absolutely amazing. But extortionate wifi and seats that barely moved, making me unable to sleep, didn't do a lot of favors.

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

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.

Wonderful experience from start to finish. Extremely nice flight staff and much better food than other airlines I have used. Arrived right on time.

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.

Very good except for the boarding process which was more hectic than it should have been

My flights with Aer Lingus were very good and I will definitely fly with them. Again in future trips to Ireland and Scotland.

Generally a good experience except for boarding in Naples on the flight back to London. We were all standing around for at least 20 minutes maybe longer as there was no seating.

Seats, WC,sizes for today's generation adults, and if technical problems arise a complimentary coffee, water nice for waiting one hours, the rest is perfect (pilot and cabin crew)

Boarding was smooth and quick. Flight departed on time. Equally evacuation upon landing was from both the front door and the back doors. Bags were on the conveyor belts before I got there. Excellent service.

The terminals are far away, be prepared to walk. Also, You climb stairs to the plane since there are no aero bridges. Boarding was haphazard not in multiple groups, so stand in line early. Hard to find place to stow cabin baggage if you are behind in the line. You can purchase food on the plane. There are vegetarian options.

First -the flight was late - more than two hours Second, not even a bottle of water at bord to give for free for this inconvenience. Three-at landing ive realised that I've lost one of my ear plug headphones and been very desperate to find it with my torch, the crew not helped at all more than that they asked to leave the plane as everyone did before me. This was the last flight from that day- extra 5 min for me with a bit of help from crew - would have bring a super review. I guess this days humanity disappeared!

I got caught using a stolen credit card number. Michelle Siziba is my name Nice to London Gatwick on 7/31/25.

Not happy with price of luggage or that we had no choice but to pay whether cabin or hold. I didn't book seats but this is unnecessary extra money along with suitcase

We accidentally purchased twice the bags we needed. Our fault, but the ticket was not clear to us, and it asked us to purchase bags at checkin. When we notified them to get credit back at the airport, they said to contact customer service. We flew the flight and then contracted customer service. They said no credits after the flight has flown. Not customer service oriented at all. They know we didn’t check that many bags and kept our money for a service they did not provide. Be aware and very careful of what you are purchasing from them because they will not make it right if there is an error.

sadly in Basel & Naples- no jetway we had to climb up and down stairs with our max size carry-on luggage, which was not fun!!!

This was our first time using them. I gave okay ratings for food and entertainment because it was minimal or not provided so I couldn't judge, but much better than most budget carriers we have ever used.
