We boarded the plane and were about to take off when we were notified that the tires had to be checked. Upon inspection, they were found to need replacement, so the entire plane had to be deboarded. After we exited the plane, United staff forced us to stay in the gate area by posting "Do Not Exit" signs on the doors connecting the gate area to the terminal. Many of us had already rebooked our flights and had no checked bags, but they told us we could not leave. This seemed inappropriate to hold people under false pretenses. When the agent told us we could leave, I asked them to please take down the "Do Not Exit" signs, as they were misleading. The agent refused, and I told them that it didn't feel right to hold people like that.

Flight attendants had a little attitude. Food tastes no good.
Very poor. The flight was delayed from Toronto because some forget to do there job . I got to my connecting gate in San Francisco 10 minutes before the departure.but this didn’t let me board even though the flight was still there for an other 30 minutes. The the gentleman at the unite airline desk told me that they usually wait for passengers but air Canada called and told them not to we I been rerouted to Manila instead of Hong Kong . In San Francisco they mad me check in my carryon bag . I was told the it will directly go yo ho chi minn cuyt but I was told that by the Vietnams airline desk that’s not there I’m 10 hours behind my scheduled flight and looks like I I’m going without baggage. I don’t have a chance of catching ..
It was all good flight was on time, service was good I enjoyed a few movies and everything was smooth
We tried to upgrade to economy premium but were told this was not possible as we had booked through United Airlines (and Air Canada was operating the flight). This seemed silly given there was ample space in economy premium. Additionally, we had to wait almost 1.5 hours upon arrival to taxi to the gate. Otherwise, the crew were very pleasant and passengers were friendly.
headphone jack didnt work for the first flight and not much variety
Connection coordination with Star Alliance partner could be better. Lots of check in setup was not interlinked between operators.
The seat is too hard and my back and bottom are having servers pain
There was no lounge for passengers waiting before boarding the aircraft at F65, so passengers are just sitting on the floor or just spread everywhere the premises before boarding.
The food was terrible and they lost my luggage which created a lot of issues.
The baggage drop-off for Air Canada in Toronto for passengers flying international was terrible. One of the worst experiences I have ever had. The line was ridiculous; there was no one to help facilitate people avoid confusion, and the baggage system for the line I finally ended up in had to be re-booted right as I got to it.
Horrible! Rude flight attendant, barely any service on such a long flight. I wouldn't recommend Air Canada to anyone.
Smooth ride but I wish they have better food selections.
Aircraft is designed with all 3 washrooms at the back of the plane, meaning that when there is service underway, there are no washrooms available and it gets very crowded at the back of the plane.
The flight was delayed, but not for weather. We landed over 3hrs later than planned.
The stag were helpful, kind and liked the passengers. The plane was pristinely clean! Great flight!
Too many delays. Seats too small. A budget airline. Will never fly Air Canada again.
Horrible, we were on a little DeHaviland 400 that was really small and shaky. I am 5' 4" and I had to duck my head to get in it felt like an old war plane.
It might have been closer to being on time. Maybe next time I could fly from London to Toronto?
Air Canada canceled my flight last minute and I gave me next’s day night time my flight. No accommodations at all. I have a function on Xmas eve. So I had to took rental car last minute.i never ever book a ticket with Canadian airlines at all.
