Liked getting into Milan at 10 AM. Also ok to get into LAX at 9:35 pm. - less traffic driving home. Layover a bit long - say 3-4 hours each way. Montreal airport kind of grim these days. Would lose the duty free area. Think art versus advertising. Maybe local shops and food spots. And keep layover short - like 1 hour on Finnair in Helsinki.

Would lose the duty free area. Think art versus advertising. Maybe local shops and food spots. And keep layover short - like 1 hour on Finnair in Helsinki.

Upgraded to sit at the exit door so good leg room.

I had a good experience. I liked being informed about the status of my luggage

Orderly boarding. The flight to Montreal was difficult to get to on time, but had help from staffer.

The food on this 5 hour flight was a cookie or pretzels.

My light was not working, I requested a meal without carrots( due to an allergy). It was not provided, so during the 13 hour flight, I was only able to consume bread and a small fruit cup. The air host was not helpful at all.

In-seat entertainment was great. Gluten free food options were very good and they gave a lot of food.

Staff was very courteous and kept things organized. We will definitely use Air Canada for further travel

I am very tall. All airline seats are a bit uncomfortable.

There were a lot of empty seats so we were able to spread out and be more comfortable. The food was decent enough. The crew, however, there was one flight attendant who put a hand on my grandson as he was walking to the bathroom and told him to stop. He’s 13 years old and didn’t need an escort so I don’t understand the necessity of putting a hand on his chest and saying “stop”. My grandson was confused and embarrassed with no explanation.

Poor food on flight between Toronto and Stockholm Airport Toronto too crowded

Business Class Configuration was excellent- private and comfortable. Crew and service were excellent. I really appreciate Air Canada cabin pressurization equal to an altitude of 8,000ft. Upon landing, I felt more alert and refreshed than typical for international flights

Hard to use tables and TV screens interfere with the enjoyment of flight experience. Other than that it was a smooth and comfortable ride and we were well taken care of.

The entertainment screens need to be updated. Very difficult to navigate through with old equipment.

We boarded the plane and waited for 30 minutes ultimately for them to cancel the flight due to engineering issues.

Excellent flight overall. Lufthansa Business service was excellent with great cabin crew and very good food and wines. The seat comfort was excellent. Only a slight reduction in score due to the 747-400 being a relatively loud aircraft these days.

Good service … bus transfer upon arrival from plane to terminal: atrocious!!!

Love the little chocolate bars, and consumer rights in EU regarding stepped refunds when flights are delayed.

Nearly every flight was delayed, I missed a connection at one point and the solution was unbearable. Added nearly 12 hours of travel time to my itinerary and was given no recompense.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

A great flight. The crew was excellent too. Of particular note of excellence was the gluten-free meal which was one of the best offerings I’ve ever had on a plane. Outstanding work, BA chefs.

Captain sick. Unable to get replacement so delayed me 30 hours, many others delayed 54 hours. TOTALLY DESTROYED ALL MY PLANS, including lost my rental car which would now cost over 5 times what I paid so stuck with buses n trains... lost hotel reservations.... HORRIBLE!!!

Easy boarding, very friendly crew, short flight so no entertainment… needed cc for all food and drink purchases…. clean and on time … that is all that mattered… so overall very good.

I had a great experience on this flight! The crew was extremely helpful and attentive. Seats are very comfortable and the in flight entertainment was excellent.

The boarding call announcements versus the Staff announcements versus the digital signage board on the out-going and returning flights WERE NOT IN SYNC. I was sent through check and re-checks 3 times. WHY?

everything to do with KAYAK was terrible. Your customer facing departments are utterly useless, timewasting and unhelpful.

The onboard service was fantastic, really in a class of its own

Delayed due to a technical fault, one small bottle of water, no USB charging point Not much to like

Boarding was fairly chaotic. One of your employees clipped my ankle as he was passing with an empty wheelchair and not only did not apologize but stated something to the effect of “oh forGod’s sake.” There was plenty of room for him to pass. otherwise, everything was excellent.

With three empty seats across the aisle from me I politely asked the crew if I could sit in one of those seats. They initially told me I couldn't do it for my safety. When I pressed them again they blamed the captain. So which was it? I didn't appreciate either nonsense explanation simply because they didn't want to honor my request.
