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

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.

Terrible confusion btw air Canada and United. Wasn’t able to change ticket because I had purchased on kayak. Rethinking booking tickets on this site, and will try to avoid United and aircanada going forward.

The plane is too cramped! Zero leg room and when the person in front of me put their seat back they were basically laying in my lap.

They canceled my flight and then refused to reschedule me on another flight. I had to take a train. No compensation. I won't use Air Canada again.

Always good Thought the seatings were a bit tight for food. Made a mess with salad and oil.

On the flight from Montreal to Calgary the flight attendant we had was excellent. Unfortunately I did not get her name but she made the flight very comfortable and enjoyable.

I did the online check-in as soon as it opened, including all the required info. When I got to the airport to drop off the luggage, Air Canada system wasn't finding my PR card info, which took a long time to resolve. Every time I fly with Air Canada, there is always some technical glitch.

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.

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.

The flight was ok, the flight attendants were lovely, the movies were good, the food was ok, and I am just sad because my luggage didn't arrive with me in Iasi because the flight from Vancouver to Frankfurt was delayed and then I barely made the rest of my flights. Also, there was no real support once I got off each of the flights. There was nobody to ask about gate or where to be and for example when I got off in Vienna to catch the flight to Iasi there was no screen where I could read the gate and time of departure of the plane. I was going crazy trying to find the plane to Iasi and I barely made it. When my luggage finally arrived home it was broken. The handle was completely broken and that was not so good. I am in a visit here, in Romania, and I will have to buy a new luggage.

It’s not bad, simply it’s not as it used to be years ago.

Pretty standard. Crew was helpful and friendly. Plane was clean and food was good.

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?

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.

Not the quality I was expecting from a company that has been around for ages and charges high prices

Crew very helpful and friendly. Food is so so. Main meal is not always the best. Did have a choice of a snack part way which was either a cookie, corn snack, or similar. Second kind of meal was basically like a pizza pastry that really wasn’t a favorite but probably a European snack? Screens and selections of movies, tv and such were good. No WI-Fi unless you buy so no free texting or such on the long flight but I think that might be any overseas flight.

Plane and seats ok. Dinners going and coming back were not fantastic. Breakfast from Seattle to London fine with bagel, cheese and fried egg. Second meal on London to Seattle not my favorite of kind of pizza sauce in a pastry. Came with water about three different times on each of my long flights. Staff on all very friendly and helpful.
