This has been the worst experience I’ve ever had. Basically, I lost my round-trip tickets because one of my last names was missing, and you didn’t allow me to correct it. I had to purchase a full ticket again. Once I get home, I will start legal proceedings against you.

This has been the worst experience I’ve ever had. Basically, I lost my round-trip tickets because one of my last names was missing, and you didn’t allow me to correct it. I had to purchase a full ticket again. Once I get home, I will start legal proceedings against you.

The crew were polite and courteous. The Pilot did an excellent landing. It was very smooth and gentle. My only regret is that I was charged twice for my luggage . The attendant gave me no receipt . I didn't realize until I was about to board. How can this be resolved? Thank you.

Very smooth flights Toronto to Rome and return. Crews were great, food was fine but very narrow seats and limited leg room. Aisle seats on our return helped with a bit more space.

YUL AIRPORT is the worst. 1 Hr to Get out of the plane, 1 Hr To Cross the Border. 1Hr waiting to be pick up curbside. Trafic is ubeliveble.

It’s ok just the boarding point is far too far

Check in slow even though completed online check in, there was no bag drop available so had to query for 90mins as only 2 staff on desks.

Flying to a far away destination is a miracle in itself, so please take these with a grain of salt. The seats are a bit tired, and need a freshen up. The entertainment could be a bit newer, especially with all services available now. The food really is where we need help. But again, flying is a privilege, so all is good.

Not so much porter it's your site! Not good

They are a sister company with Air Transat and the two companies do not work well together. If you have any issues the two companies will blame each other and you will miss your flights. The help line does not help

Never book through a third party. Book through Air transats website. Terrible process to get help and many issues happen with them and sister companies because half the flights you book with them aren’t even through air transat.

I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

I don't understand the concept of paying to get your personal luggage onboard and then asked to check it in.... either sell the space or don't, its a hassle to carry those all through the airport just to make a check in at the last minute.

The food was great and the service and attitude was amazing!!

It was a great experience. The only thing I would have changed was that the bathrooms were never cleaned and they got very dirty.

Old airplanes small seats expensive tickets, not as expected overall and not comfortable according to the price

It was an OK flight with below mediocre service by their flight attendants

Wasted a lot of time trying to find the CDG lounge - it was not next to the connecting flight gate like the Air France staff said.

My experience was good overall, the quality of the food really decreased! There used to be a choice between meat and fish now it’s between chicken and pasta! In the choices of entertainment meditation has been added which is very good. Soft chair workout to improve blood circulation and avoid phlebitis should be added.

The only reason the overall rating wasn't "excellent" was due to problems in claiming luggage. The bags are delivered to the main area (Cinta 35) for domestic passengers, but to a DIFFERENT ROOM for international arrivees. After waiting 30 minutes, someone (who didn't appear to be from Air France or the airport) told us to go to another area. There we found our bags, which appeared to have been awaiting us for a while. We had to go through a bag check before leaving the airport. If we had been alerted to this possibility, or better yet, been to go directly to Cinta 34, we could have eliminated quite a bit of waiting.

Much better than the major US Carriers especially in Biz Class.

Too hot. Asked for an extra glass of water and was ignored. Asked to sit in empty seats that were open because it was so hot and crowded and was denied and the seats were empty the entire flight

Terrible leg room - I’m 5’3” and my knees were touching the seat in front of me. When the person sitting in front of me leaned back, there was about 15 inches of space between my head and the TV screen which made it awkward to view movies. Last year they had decent food, but this year the only tasty item on the trip was dessert.

The flight was delayed leaving Philadelphia due to “catering” and consequently arrived in Dublin some 75 minutes later than scheduled. Consequently this caused me to miss my connecting flight to Glasgow and I had to spend the night in Dublin.

It was truly a horrible flight. We were delayed almost 2 hours. The seats were so tiny, my legs were hurting the entire flight. When i finally made it to Ireland i missed my connecting flight because we left Newark late. I will most likely never fly Aer Lingus again

Coming from the EU to the USA, Aer Lingus is a very good choice. You clear U.S. border control while still at the departure airport, so when you land in the States, you don’t need to go through the entry process again — very efficient and fast. In terms of comfort, Aer Lingus is better than the usual EU carriers like KLM, Lufthansa, or Air France, and also better than United. There’s more legroom, and the crew is helpful and kind. The food is average but slightly better than most airlines. Overall, the crew is definitely better than on American Airlines, though not quite at the level of Virgin.

Best travel day I've had in a long time. Everything went perfectly, no delays. 10 out of 10

Seat is business could have been a lot cleaner, but space was nice and seat was comfortable

Terrible. The test of an airline is how they deal with problems. There is very little to differentiate between airlines. Aer Lingus failed absolutely. They lost one of my bags even though we had more than a 2 hour connection in Dublin. Trying to get it back has been awful. In checking on line I can see that the bag is in Edinburgh and it was supposed to be delivered today. It wasn't. The number we have in the UK doesn't answer. I had to pay for an international call to speak to somebody. All the woman at the call centre could say was be patient wait. I can tell you when it will be delivered nor can I tell you who the courier is.

A little late, but an overall pleasant flight. Staff pleasent hand helpful, a great start to our holiday.

Poor check-in experience in Manchester. Delayed boarding and check-in agent never explained how to transfer in NYC to JetBlue.

The crew were fabulous. The flight was bumpy and I always like the captain to tell me what that is about or my imagination gets carries away.

I liked the behaviour of the crew members.The flight was good.

Food can be better. Taste and option, the pasta wasn't the greatest.

The internet connection was perfect, and the updated entertainment systems that allow me to connect my Bluetooth earbuds was excellent

Flight was fine and on time. But no entertainment system and little leg room.

I swear airplane seats keep getting smaller and smaller but everything else was great. Smooth sailing and we got in early.

No food to provide, they forgot that, in some cases, people stay at the airport for hours without food. Now, to provide them with food, they have to ask them to pay, because some don't have money. That way, they can't eat.

After a long flight from Tokyo, our connecting flight home was canceled due to “maintenance” while we were on our layover in Toronto. Very frustrating to close out our honeymoon, although I’m sure others had it even worse during last week’s strike. Air Canada staff at Pearson Airport are the one thing that kept me remotely at peace during this — they were very helpful and deserve a lot of props. But I would not fly Air Canada again.

It was good to receive a card for my birthday

Horrible flight cancelled had to buy another very expensive ticket

All was good, except my USB charging did not work, so my phone got drained and I could not charge it. Same happened to my neighbour.

A bit more space? Not practical, I know. I felt squished in but part of that could have been the man sitting next to me.

The plane (Mitsubishi CRJ) felt old, creaking and not very new. The crew was okay. Hot water provision was broken so hot beverages could't be served.

Not bad. We had preboarding tickets but the preboarding was badly managed. We lined up behind all the parents with little kids etc and when we got to the front of the line the attendant deliberately turned away from us and ignored us until I asked to be allowed to go to the gate. She started telling us that we had to wait until I told her we had preboarding then she let us through.

The plane was over an hour late taking off... the plane was rather tired looking, seat cushion was thin and uncomfortable, the sound on my entertainment system wasn't working... crew are not friendly.

Everything well done and customer oriented There entertainment system is difficult to navigate

They delayed my flight from Toronto Pearson for one hour and Frankfurt to Abuja for 2HRS, So sad

Overall excellent service and Frankfurt Airport was very efficient and clean

The aircraft was old, there was no charging sockets, and the seats were narrow and uncomfortable even though I had exit row premium seats.

Always having a good experience with Lufthansa. I prefer them over anyone else. Sometimes prices need to be more affordable. Munich airport is clean and good, services are available and it’s overall a good experience. I have been flying with Lufthansa for close to a decade and I hope many more to come.
