Flight was cancelled. Had to wait around the airport for 5.5 hrs for later flight. Entertainment system was not working.

The speaker flight attendant talked over was way too loud. Hurt my ears -had to take out hearing aids.

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.

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.

Air Canada is the worst but the only option for my route

Overall, a good experience. The crew were not as friendly/helpful on my flight from Toronto to Nashville, but they were nice enough. I asked for a coffee about 45 min before landing, the flight attendant acted put out at the request.. apparently, they forgot about it and when I asked again they said it was too late. It was the only thing I asked for on the flight. Needless to say, it bugged me.

Everything was on time, loading and unloading went smoothly, and the staff were positive. I wish the seats were more comfortable and had a little more space. I was in the middle seat and had to keep my elbows in so I didn’t bump my neighbour’s arms. Would not like a middle seat ever again. Would fly Air Canada Rouge again 👍

Easy check-in at yvr Pleasant flight crew More comfortable economy seating than usual
