We had a very long delay. First the inbound flight took a while, then maintenance, they “fixed it” to then do boarding and leave the gate, and waste a lot of time to have to go back to the gate and eventually deplane. Had to wait for a new aircraft, wait for a gate, and do the whole thing again. Instead of leaving at 9:50am we left until past 1. I could’ve not woken up at 5am, or spend some more time with my family if they gave more grace period of time between flights to give some time in case of any issues. But they have to make all and every dollar possible

Most expensive flight… and they are trying to pinch more and more money out of you. Baggage, snacks, pillows, headphones… — so many airlines do far better than this… surely a national airline can do better?

Air Canada should allow basic economy passengers to upgrade if they wish to do so.

My second flight ended up being through United and it was fine. Again, just frustrating that it was so late.

I had written all my complaints on my trip from Grand Junction to Denver so I will repeat it here! I was absolutely appalled that I had to pay for a regular seat that I choose 24 hrs before boarding! Also I checked my large bag which I had to pay for as well, and by the time I boarded all the room in the bins were gone so also had to check that one. I noticed people pulling out oversized suitcases, bigger than the measurements stated for carry on, and also large pack packs stuffed full! So these people were taking up 2 or 3 spaces that the rest of us should have been able to use but couldn’t! NoTV on the flight! Thankfully I had downloaded the United Airlines app and was able to watch movies on my phone. Don’t remember the last time I flew in a plane with no movie screens!

My flying experience with Air Canada was good but the wheelchair situation wasn't good at all and if would be good to make sure that they have the appropriate services available for your traveling passengers.

Air Canada flights offer excellent service. This flight from DEN to YYZ in an Airbus A220-300 was so sooth it was almost like spending a couple of hours reading a good book, except for the cabin crew who provide friendly, thoughtful service throughout the flight. Kudos to AC pilots, cabin crew and management. I’ve now added Airbus 220.300 to my preferred list if planes to fly in.

Lots of delay! Cheotic and disorganized! Aircraft had technical problem and was stopped and returbed to the gate while taking off! . United States is sinking under Joe Biden!

Ops was very poor. 2 of 2 legs were both late. Air Canada changed our seats 3x and my friend and I never did get to sit together. Flight attendant opened the lavatory on me and was not professional about it. Food was blah. The worst part is that the flight was so late from Toronto that we missed our connection in Athens. We lost out on other airline tickets and nobody even said sorry or tried to help. Our return flight was cancelled and my friend and I are rebooked on completely different flights next week.

Legroom was not good and can be improved and food needs upgrade.
