It was a nice and smooth trip. Gave a friendly environment throughout the journey.

Meal and drink service was good. Old plane with old business class seats were quite disappointing

The flight was smooth, the plane was spacious and clean, the staff was kind and the food was decent.

Pretzels were a bit dry and dusty, however it is nice to have a choice between sweet and savory snacks.

Flight crew was great, and even the crew for checking bags! I had a question for a friend of mine flying tomorrow and the man I talked to was awesome and answered my questions and looked up things for me when he didn’t have to! I was able to give her current & accurate info for her flight and she was so appreciative too!!

Never flown with Air Canada before, but it's now a top choice! Loved it!

Horrible crew, horrible seats configuration, ridiculous space in the toilets, Air Canada is no longer a option.

Crew at gate and onboard were just very OK, not very friendly and honestly seemed bothered to be there. I will give a shout out to still selling headphones for those who forgot.

Flight Boarded and departed on time. The Flight crew was very friendly and accommodating. The aircraft was clean and free from clutter and debris. I will be happy to recommend Air Canada to my friends and relatives for their flight needs. They were very attentive and responsive to our needs as Senior citizens.

Another good flight experience with Air Canada. The business section did not feature the full length sleeping arrangement, but this was a shorter trip. The food was excellent. But the flight crew was truly top tier: friendly, cheerful, helpful at all the right times. Air Canada truly outshines all U.S. carriers.
