The ease of boarding was good. I wish they had something to eat on the plane.

The ease of boarding was good. I wish they had something to eat on the plane.

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. The check in desk wasn’t even opened on time (3 hours prior to departure) and there was no communication about when it would open or why there was a delay. 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.

Seats were less comfortable and tight from Newark to Dublin, than my second flight ( small segment from Dublin to Lyon). Movie audio was with frying sound overall. Yet the worst was as follows: one male, (dark hair , glasses on) from the crew member was so cold and rough, while I remained with constancy polite and kind. Per exple with the noise level I could not hear him at first for beverages, he rolled his eyes at the third times I finally heard him. From the start, loading my small hand bags , he directly spoke to me and said “ I had to keep my shopping bad by my seat, under , while there was sufficient room and I was among the last to sit. I show him the space , his face was always dull, stoic, not welcoming as the usual crew members from any airline companies are. When I think of my experience I liard w Aer Lingus, this is the image that gets back to me. Needless to say that as a passenger and client, I felt belittled since all this happened in front of the surrendering passengers. It s an affront and not a pleasant feeling especially when being traveling which oftentimes involves stress with carrying, and making it on time. I m not happy with the experience I had to be honest and I fly four times a year. Thank you for allowing me to share this statement with your company.

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.

Really helpful staff at the airport and the flight was comfortable with good entertainment options and food service

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. .

One cold drinks service. No snacks with drinks. No tomato juice or apple juice, coke - only fanta or sprite then ran out of that. Went to gally after meal service no one there / no self service for water at least. Waited 25 min for cabin crew to assist. No recycling of cardboard/ plastic - all put to garbage. Breakfast was a nutrigrain bar and an orange juice. Also I'm sure I booked a flight with checked luggage allowance but had to buy extra when I had my booking confirmation. Movies were good. Chairs comfy. Pillow and blanket and ac vents.

I would definitely use a Linus again, the price was right, the service is excellent. No delays. Wish I had a direct flight from my hometown Detroit.

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