No TV on the flight. The charging outlet was not working. No food, even a sandwich. The served orange was poor quality.

I liked that the staff members at the airport were helpful and very pleasant to work with. Flight crew were also a great crew who were helpful and I was happy for their help boarding. Overall a pleasant trip home.

Business class seats were quite old. Flight departure was delayed . Food service was good

Selected seats 5 months prior to date. Had email confirmation and seats were not honoured. Family did not sit together

Fantastic dinner! The chicken with the coconut rice was amazingly good! Excellent service!

Air traffic delay meant boarding started, then plane was evacuated and passengers sent back to the terminal for 1 hour. Very little information shared.

Our AC flight was canceled not once but twice on the same day to Quebec City at Toronto Pearson Airport. 2;30 AC and 9;40PM AC flight. After having our 2:35 flight canceled, we were bumped the second time because of large student groups visiting Quebec City. We were sent to Montreal on an 11:30 flight which landed close to 12:45AM. We were given a hotel room at the Marriot Hotel next to the airport. We had less than 4 hours sleep before we being taken to the airport for our 7AM flight to Quebec City. We didn't have much time to use our vouchers given for breakfast once we had cleared customs for the 2nd time since leaving Toronto Pearson Airport. We missed a full evening in Quebec City and lost our hotel room for the night. We were exhausted the next day and missed an excursion we had planned. My wife and I are both seniors in our seventies, and we weren't happy to be treated in this manner. Air Canada could have used a larger plane to accommodate us and the other ten or so people that were bumped from their flight to Quebec City in order to accommodate student groups. We will endeavor never to fly Air Canada again in future and we will not recommend flying with this airline to our friends and families.

Better to not serve food if those are the options

It was a good experience flying Air Canada for the first time

They did not let us board because one member needed a transit visa, which was not evident at the time of ticket purchase.
