As always, it’s a pleasure to travel with KLM. It is one of my favorite airlines.

Outstanding even though the 330 was one of the oldest in the fleet. The difference was the attentiveness and responsiveness of a really experienced flight attendant. For airline food great variety of interesting choices and good tastes supported by a good wine selection.

I’m grateful for the KLM Air France shuttle bus service to Ottawa. However due to construction and other issues related to the chaotic Uber pickup system at YUL, it’s a challenge to find the Kelios bus service to Ottawa. The signs are not clear or even available. No staff to guide passengers. It’s a stressful experience.

Flight was on time, staff are friendly and helpful onboard.

The immigration hall in Amsterdam was understaffed, so passport checking was slower than it should be for a major airport. They need to get the automatic readers up and running for non EU passport holders. Waiting in line after a long flight feels a bit abusive.

Klm start boarding while somw air issue in the plan

I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

Good food. Excellent crew service. Clean aircraft. Narrow seats and isle.

It’s chaotic at the bus stop outside of the airport because of the Uber meeting point. You need to be alert and look for the KLM bus which is not branded or labeled. Incorrect information was provided to go to gate 28, when in fact the bus was at gate 27. On the plus side the bus left early and arrived early to Ottawa.

Great flight because I upgraded to Premium Comfort. Made a huge difference in the experience.

Flying business class saves you. Once you get out of the terminal and onto the plane, it’s fine. The traffic at the gate is a horror. No organization at all. The fact that Business class is promised early boarding is a myth.

Every time I fly LOT, I swear I will never do it again. And changing planes in Warsaw is a horror. Not even remotely organized. I can only feel sorry for the staff who have to put up with it.

The seat was paid for but given for some different person .

Good in general, but i think the chair is not comfortable for traveling more than 2 hours ..

Once again very friendly helpful staff A short flight but not only on time actually a bit early

Everything was very good. I felt that the value received in paying for Business Class tickets was very good. The entertainment offered was plentiful, but could be improved with more recent options as well. By no means a deal-breaker. The staff were awesome, in the airport, at the gate and onboard.

bus ride to the plane was very crowded and had to wait a long time to get to the plane. The flight itself was great.

Together with my family, we all agreed that the LOT crew provided the most wonderful service that could be. We are grateful for such a great experience they provided to us! We will return and share our experience with all our friends and family.! Keep up the good work!

first and above all I liked the crew; everyone was one of a kind, friendly, professional, and eager to help.

The boarding was delayed several times. The take off was two hours late.

I don’t like that an equipment change caused my seat to change from 23A to 44A. The boarding was also delayed. The crew were excellent, however and very attentive. The food was not bad.

Our flight crew were terrific. And they handle a difficult passenger with finesse.

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 male attended that served are section was a snob. He did not answer my call light when my wine spilled all over the floor. I did not push it again or drew his attention to it. He just ignored the call light when he came to give us our meal, serving the people behind us first. I did not push it again or drew his attention to it to see his reaction. It was so obvious that he was ignoring us. We were in premium economy!

Not great , just ok . I expected better food but it did not deliver . Flight staff was ok . The guy at the drop off bag counter was the only saving grace in this whole trip . He was pleasant, friendly and very helpful . You couldn’t ask for a better assistance from him .

There was 2 hours delay before boarding and 2 hours delay after boarding while waiting in the plane

They lost my baggage and I still have not got it back. Disgrace

Excellent apart from transport to actual plane 10 minutes from the actual gate , walking out in the tarmac in the rain and having to climb stairs to enter while holding luggage.

A couple of minor delays in boarding but very professional and efficient staff.

Not the best crew. Extremely annoying with mask wearing. Even when I was eating and drinking they would come up to you to tell you to wear your mask. Extremely annoying.

I cancelled my flight in March and have been waiting for 3 months for the refund. Both flights have taken off and returned now and still no refund.

great flights both ways on time both ways.staff(ladies) where great at check-in.

Food was great, I wished there was better options for movies.

737-8 Max is an awful design. Toilets in the rear are inaccessible for most of the flight due to service carts.

Flight was first delayed for 1 hour, then was cancelled. Communication was poor. I ended up booking a new flight on a different carrier to return home. I heard people in my gate area on the phone with Air Canada customer service who had to inform them that the flight was cancelled and they weren't being helped because the system hadn't caught up with what was actually happening.

Other airlines offer free wifi to business class customers, Air Canada does not

Every flight was canceled and they didn’t care much about their passengers

Crew attitude and attentiveness. Comfort of the seats. Entertainment options.

this flight was exceptional due to the plane itself being updated with longer seat belts so no need for the extender and access to a tv.

Chicago Airport made it impossible to make our flight so my 7 year old had to sleep on chairs through the night and I am still up. Terrible experience.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

Overall, the service was excellent, the crew verry professional, and departures and arrivals were perfect.

Missed flight. Requested assistance for my father and he did not receive it in Paris.

very small seats the scree did not work. I could not watch anything for 9 hours.

I like entertainment on the plane once I got it to work. The touch screen really had a hard time responding to touch. Boarding was excruciatingly slow. Getting through passport control was bad enough but security had a line of us not moving at all while this team of security people took their time going through every item of one single passenger, not letting anybody else advance (only one lane open while the equipment was there for 2). I would have missed my connecting flight had it not been an hour late itself. I know the airport is not the responsibility of Lufthansa or Kayak but I mention it as the reason my experience was not great.

The flight was canceled and the airline didn't even bother to notify passengers. It was Kayak that did a great job.

Working outlets at the seat would have made it better.

Transit in Munich airport was terrible, staff is rude! Sitting on row 53 was bad the food was not enough.

Flight was overbooked. Food was awful. Seats in economy class are a torture: narrow, not enough leg room. The airplanes classes are like casts: rich, average and poor…That system is a shame. Pilots were Excellent !!! Thank you!!!!

Air Canada is by far the worst Airline on the face of this planet. Only delays and overbooked flight with very poor customer support. Avoid them at all cost!
