We ordered kosher meals, did not get them We didn’t eat The corresponding flight from Brussels was worse as it was a very low cost flight with no entertainment whatsoever and no kosher food either We had to pay for a bottle of water to take our medication In other words, my sister and I had to endure a 20 hours fast

My husbands flight last night Vancouver/Sydney was 90 minutes late in leaving. My flight tonight Vancouver/Seattle was also late in departing.

My mother, 80years old, had arranged for wheelchair assist to and from the aircraft cabin and in the airport but, no one showed up for her to de-plane. Apart from Air Canada having a reputation of being late for every leg of its flight so nothing was new this time so this time they did worse by not assisting seniors. I guess our whole family is done with this airline

Because we had to drive to Toronto due to delays in Windsor on our return we had a car in Toronto so we had to drive home

6 hours late on departure from Vancouver due to crew schedules! Unacceptable

I missed my niece’s high school graduation because the flight was delayed 3 hours. I broke down at the airport and on the plane several because of how heartbroken I was to miss it.

The flights were pretty close to the scheduled times, all connections were smooth and without additional delays, and my luggage was accounted for throughout the journey. All in all, this was the best travel experience I've had in quite some time.

The flight crew was extremely accommodating, finding a place for my guitar. Thank you so much! Departure time, however it was delayed almost an hour because the plane was not at our gate on time. We did make up most of that timing flight, however, but it is always annoying to be delayed for that length of time. I was looking forward to the, but, honestly, it was really bad. Overall, however, my first experience with Canada was really good and I would recommend you. Thx.

My flight was from Charleston, SC to Halifax, NS with one layover and the same on the return. My flight to Halifax was good! The employees at check-in were helpful and friendly. No issues there. My each leg of my flight to Halifax was pleasant. The air crews were excellent, professional and courteous. Arrival in Toronto was uneventful, and the gate agents were friendly and helpful. The same for my flight to Halifax. My return trip was not so pleasant. The flight from Halifax to Toronto was great, with everything I mentioned above: friendly check-in staff and gate agents and quick boarding. It is when I got to Toronto that things went off the rails. In short my flight to Charleston was cancelled about an hour before boarding due to weather in Charleston. I received a text stating I would be rebooked within the 1/2 hour, and I was... on a flight at 6:40 pm the next day, more than 24 hours out! I absolutely could not stay in Toronto that long as I had to be back in Savannah for work. I went to the Air Canada service desk and here is where it really came off the rails for me. Please understand that up to this point every Air Canada employee I had interaction with was wonderful. However my experience with your service desk left much to be desired. As I stood in line with about 30 other people one of the agents announced that for those of us whose flight was cancelled that we had been rebooked, and to please follow her so we could be "escorted out". I turned to someone in line and asked what that meant, "escorted out"? They had no idea. As someone who has limited international travel experience I had no idea what to expect. One of the passengers asked her about accommodations, and was told basically that the cancellation was due to weather and therefore not Air Canada's problem (paraphrasing, but that was the message). She then proceeded to herd a group of passengers to be "escorted out". No other explanation. I waited in line to talk with one of the agents, and happened to get the same agent who had just taken the group out. I told her I could not wait for another flight 24 hours away and asked if they could try and book me on an earlier flight. She handed me a card and said there was nothing they could do and to call the 800 number to try and get another booking. She was extremely short with me and acted as if it was a bother to answer my questions. She said that I needed to be "escorted out". I asked her what does that mean? She explained that the international side of the airport closed at 10:00 pm and that we could not stay in the terminal overnight. I then asked her where I was going to be escorted to, to which she answered "the curb". The curb... outside of the airport? Yes, the curb. That was all she said. I left the desk to call the 800 number to rebook my flight. The gentleman I spoke with on the phone was pleasant and very helpful, and was able to get me a flight out at 7:55 am the next morning with a connection in Chicago. Absolutely wonderful experience there. I then proceeded to walk through the terminal to find my way out so that I could get a hotel for the night (another $225 I was not expecting to spend). I didn't realize that I could not exit the terminal without being "escorted out". I, and several other passengers, found our way at the far end of the terminal which was, apparently, closed to all except domestic Canadian travel. We were not aware of this. We were approached by a young lady with Air Canada and told that we had to turn around and we were not permitted in that section of the airport. She was abrupt and quite rude about it. Not a pleasant person. I made my way back to the service desk so that they could escort me out. About an hour after getting my flight taken care of I received another text that my morning flight had been delayed by 45 minutes. Not a huge deal as I was able to make my connection in Chicago, but it did put me on edge expecting another cancellation. My flight from Toronto to Chicago and then to Charleston was with United Airlines. The flight to Chicago was pleasant. I was fortunate enough to have a seat to myself. The flight from Chicago to Charleston was on a smaller plane, two seats each side, and the individual next to me was not a small individual. I had to press myself against the wall of the plane as I had zero space. Other than that the flight was fine and, again, the crew professional and courteous. I hate to complain because I know that airline employees, both on the ground and in the air, deal with some crazy things and many unpleasant passengers. I get it. I am in hospitality and I absolutely understand, and am appreciative of your associates and the jobs they have. It's not easy and, I imagine, quite stressful at times. Every Air Canada associate I interacted with was wonderful and do your airline credit, aside from those that I just mentioned above. It's not hard to answer a question, even if you're having a hard day. I also understand that things happen that are beyond the control of the airline. Weather, mechanical issues, passengers acting up... I totally understand. When it is all said and done Air Canada got me home safely, for which I am most grateful, and I am grateful for all of your associates who were professional and courteous during my journey.

It was late leaving but made up time in the air.
