Ok Did not like that the second leg of flight was moved earlier making it a rush to make

We had a lot problems in beginning but Air Canada took very good care of us

My flight was delayed, causing a shortened connection to my second flight, which led to a stressful experience. Additionally, I had to pay the luggage fee twice, for which I have receipts. Since Air Canada and United Airlines collaborate, their partnership should aim to provide better service, rather than leaving passengers to bear the consequences of an unprofessional experience.

One leg of the flight arrived late which necessitated a rebooking on the next leg. Although there were no major weather events in play, best choice offered was a 7 hour wait in the Vancouver airport for a 4 hour totally packed red eye flight to Ottawa. No opportunities to return earlier via other major hubs like Toronto or Montreal. Felt very much like national routes were no longer well supported. Adding insult to injury, entertainment system for my seat was out of order. Thought I might use wi-fi, but discovered it would cost $10 per hour! Paid a lot for the flight as it was over the holiday period. Probably won't be doing that again.

Air Canada is the worst airline I have ever flown. They lost my luggage, cancelled my flight, refused to pay for a hotel, charged me for business class even though they changed my flight to economy and there is no process to get someone on phone. Would not recommend Air Canada to my worst enemy.

Overall it was great! Seats were comfortable. We were offered snack and drink on the way to Florida but only a drink coming back. Free messaging for aero plan members was a great feature to have on board so we can connect with loved ones … entertainment like movies and shows was also a good selection!

The problem in part was with the airports, not really the fault of Air Canada. Confusing directions regarding the gate, in Seattle the recommended shuttle train entrance was not working. Simular problems in Toronto. Baggage arrived in good time. Marx Bros movie on entertainment from Seattle. I was told I was laughing too loudly, by the flight attendant. No lounge in Seattle. Lounge in Toronto excellent.

Made me check my carry on despite there being dozens of empty bins when I boarded which significantly inconvenienced me.

I arrived for my flight and was told I was now on standby as my assigned seat when I purchased my ticket was just deemed unusable 15 mins ago. My parents had to wait and hour and a half at the airport to see if I’d get in the plane. Finally when all passengers had boarded the plane I was finally told they did have another seat for me. When I boarded I saw someone else sitting in my originally assigned seat. It was in the emergency exit row and has extra leg room. I have sat in this row many times and am able to help in an emergency so no reason for me to have been kicked out of this seat. The new seat I was assigned had no padding and was extremely uncomfortable. Upon landing my back was very sore and I will probably need to see a massage therapist to help ease the tension. There was no tv or way to charge my phone on the plane. Worst flight I’ve taken in a while by far.

The flight was terribly cold with no blankets available, not even any to purchase. They charge you for earphones and for food though they provide pretzels or a cookie with refreshments. The seat was very thin and generally uncomfortable. I would not use them again though the crew were very nice.
