After my flight was cancelled the day before we got on board and could not even get a cup Of tea with milk as there was no milk. The oatmeal bar they are now serving was terrible. It was interesting that we could not get anything to eat as SXM doesn’t provide food but the people in Business class had food. I was very hungry as I never ate at the airport after being picked up by the bus from the hotel. There was one worker in the cafe to serve us all and I had a problem with my knee so couldn’t walk as quickly so ended up not getting food. Not your problem but still I was very hungry. An attendant finally gave me some hot water which I requested. It’s the first time I’ve ever felt the class distinction while travelling.

An attendant finally gave me some hot water which I requested. It’s the first time I’ve ever felt the class distinction while travelling.

Boarding procedures were a gong show. Everyone was confused and AC staff were very rude and impatient when people were confused about boarding zones

I bought a ticket from Kayak. When I got to the airport, the was no ticket. I had to pay 5X to get to my destination. No response received from Kayak. I will NEVER use them again.

My wallet was stolen while I was sleeping on the plane.

After waiting in the airport from 7am (to make sure we had enough time for security), our flight was continually delayed until it was canceled. They tried to book us on a Delta flight, which we considered and even went to the Delta terminal with our luggage (which was stowed and then available once the flight was canceled (about 15 min away) but were then informed that we would need to retrieve our luggage at LaGuardia and then recheck in to Air Canada in New York, grab our luggage, and then get to the air canada terminal and re-check in. We decided against it, took our luggage into an uber home and then drive the 6.5 hours (one way) to Montreal instead.

The seats were the most comfortable and spacious that I ever flew, and I flew more than 20 different airlines (economy)

Flight departed significantly late with no announcements being made. Woman behind me would not allow me to recline my seat so I was unable to comfortably sleep. Flight attendant not very responsive. Slow to pick up garbage after meal. Not a good experience at all. I felt like cattle rather than like a valued customer

Boarding was extremely challenging, long lines and wait time, almost missed my flight.

I checked a bag and there was only one agent to assist all customers with any issues.

Hoping for small compasation for having to rebook my trip back cause i had to miss 6 hrs work

The flight was delayed 7 hours and we were given 10 euros vouchers. This is ridiculous. The crew was not nice at all, they just did their job with serving food and drinks. Did not even apologize for the delay!!!!

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

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.

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

Business Class was very comfortable and the food and service was top notch.

The crew was very nice. The equipment on the 747 felt old.

As expected. Would have appreciated a 3-day headsup reminder as a reassurance that all is well.

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

The plane was late (as was my flight out from Birmingham the day before)

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
