At 6'2" the seat space was very cramped for economy. Otherwise good.

At 6'2" the seat space was very cramped for economy. Otherwise good.

Abandoned me in hallway in a wheelchair… which I asked for because I sprained my back. After waiting in the hallway, I decided to walk the rest of the way since someone respecting me up.. My experience with the united was totally the opposite. Wheelchair access, propped swift and save me a lot of grief. Air Canada totally disorganized.

No issues other than paying twice for my seat selection.

Bad experience boarding and flight got delayed didn’t make it to my next flight

Everything was great, clean plane and washrooms. Flight was on time, excellent boarding process

The app was great, service was wonderful, everything was quick and easy

The food on the trip Toronto to Athens could be better: the chicken didn’t taste good.

Horrible. Multiple delays for every reason imaginable. Missed connection which led to missing work. How does a plane make a detour to refuel. Do the fueling then have to refuel a second time at the exact same spot? Mind blowing.

Conflicting information provided about baggage allowance. One screen said I had a carry on and another said I didnt.

The 787 Dreamliner that we flew on was relatively new and a nice aircraft. We flew on a 777 which was noticeably older and the seats were average” but the 787 was very nice, especially for the price. No window blinds anymore, instead high tech adjustable polychromatic glass!! Nice.

The check in process at CDG was absolutely unacceptable. We arrived to the airport 3 hours and 20 minutes before our departure time, waited in line for 1 hour and 30 minutes to check in (despite having checked in online and only needing to check a bag), then were forced to check all of our rolling luggage despite the fact that all were compliant with carry-on requirements. The staff at the desk were rude and there were only two desks open, while eight people were working. We feared missing our flight because the departure board was not updated, so rushed to our gate to board once we were through security because it was 20 minutes prior to departure, only to wait another 30 minutes before boarding even started. Communication was lacking throughout the process. What a horrible end to our trip.

I like Aer Lingus so that is why I’m writing this critique so they can become better. The boarding gate was too small to board properly. Our seats were toward the back of the plane knowing we would be boarding after business class, we moved to that area after business class boarded. An Aer Lingus employee told us we couldn’t stand there. We explained we were the next group to board and wouldn’t even be able to hear when our boarding was called. She didn’t care and was not very professional. The cabin was freezing. I wouldn’t feed my dog the food. We were over an hour late coming into chicago because of weather which can’t be avoided. I asked the crew if they could make an annoucement for before whose final destination is chicago to wait and allow the people with connecting to deplane first. He said there are a lot of people with connecting flights. He said, it doesn’t matter. Well, yes it does. He could have been more considerate of his passengers.

The seat spacing was good. The food, not so good... typical airline food. 😕

I would face like to have more selections for entertainments overall it was very good. .

At check-in the unmanned machines said QR code was invalid so had to queue for over an hour to check in bags

i used to fly aer Lingus regularly but due to price - poor seating etc i have been using other carriers - i now have aer lingus in my state and the price is always the highest - i have flown to Ireland 11 times in last 24 months and have not used Hartford because of price

Nicest staff I’ve experienced on a plane! Good food, great entertainment, and they gave out little blankets that my kids loved. All in all, great experience.

The Glasgow to Dublin route was very efficiently boarded, flight and landing and disembarkation were all super smooth. Dublin to JFK flight I was very pleasantly surprised overall. This was my first time on Aer Lingus and having already come off the short regional flight I was curious to know how the international flight would go. Aircraft was solid, entertainment options were better than expected, flight crew were experienced and operated like clockwork. Main entree left a little something to be desired but the snack was very tasty. Boarding and disembarkation again very smooth and pilots got us in earlier than expected. Would definitely fly again

Unfortunately the flight was delayed for 50 min. Just as we were about to board so that was a drag. The boarding was average. The bag check in process was new to us and efficient. And the flight itself was smooth- basically no turbulence.

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