The space for seats were uncomfortable and lack of leg room . I paid extra for more leg room. I’m not a big person.

The space for seats were uncomfortable and lack of leg room . I paid extra for more leg room. I’m not a big person.

Lack of WC assistance when returning to Toronto and my 92 year old aunt needed. To walk a fair distance with great difficulty to get to the exit and taxis. We were left without assistance after departing from the airport wagon.

I was forcefully re-routed to another destination and was delayed a total of 8hours. I have still not received my bags, no one is taking responsibility. The agents at the airport lied to me that I will get to my destination same time as my previous flight where I was forcefully re-routed from.

I checked in early in Kingstown and one of my luggage was left back. I am very disappointed because it contains items I care about.

The leg room was tight even after paying extra for economy comfort plus. It was difficult to move out of your seat (I was seated in a window seat). I am not a large person. I would not book the middle or window seats again.

Not happy with Air Canada’s frequent flights cancellation and delays.

Horrible, we were on a little DeHaviland 400 that was really small and shaky. I am 5' 4" and I had to duck my head to get in it felt like an old war plane.

Flight was delayed by 1.5hrs. Once inside, people had their small handbags on the storage. The crew (male guy) was not helpful in making some space in the storage. Instead, he asked few bags to be checked-in and it was not a great experience. No attempt to help but just followed the things with a straight face. People had their literally small bags and he wouldnt not move from one storage to another even if there was space and would not let us do i as well. Once flight was on, they ran out of Orange juice, really running out of orange juice when the temp were 32.degrees outside. didnt made the sense. Onasking for a extra snack, he made a face as if he was giving me out of his pocket. if the flight was delayed, there could have an attempt to provide something extra incase people did asked.

Seats could be slightly more comfortable otherwise flight was good but

Our flight was canceled at the last minute. Someone on the flight said the exact same thing happened to her the day before. I will say they helped us book a flight on another airline so that we could still make our vacation with little delay.

I wish Aer Lingus offered free wifi and had power outlets at the seats. Overall, the flight was good. Seat back entertainment had some interesting options. Food and snack options were mediocre at best. I enjoyed the canned red wine.

In business class overhead bins were minuscule. Had to use cabin staff to find a place for my carry-on bag. Boarding process was shambolic, as “passengers who needed assistance in boarding” absorbed an excessive amount of time and attention that Aer Lingus was apparently unprepared for.

Aer Lingus was fabulous.nhowever, Aiirfare Assist who Kayak routes me to to purchase tickets for m was awful. They messed up my reservation so bad that after about six hours on the phone with them over the week before departure, I had been choice but to show up at the airport. The Aer Lingus staff were amazing and got it sorted out but I would recommend not using Airfare Assist.

I had a great experience. I wasn’t sure what to expect but the crew helped me check my bags and made sure I got in the correct line to board. It was a bit of a walk to my gate so arrive early. I would recommend securing a flight that includes checking in your bag if you remotely think your baggage is over 10kg/22lbs. Be safe and upgrade unless you are carrying a backpack or weekend type baggage.

Dublin to Boston was decent. Food and entertainment was included and that was expected for the rate paid.

No entertained. food and beverages were not complimentary. they lost my checked luggage which made my 10 day vacation unpleasant.

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.

Flight was on time. Boarding was quick and efficient. Seats were comfortable. Food was fine.

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. 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.
