The flight was delayed at the last moment quoting an absurd weather reason. This delay led to an issue with my connecting flight. I was made to run (literary) from this flight to the next one ( as they preponed departure. I was still in my DCA to YYZ flight when the boarding started for the next connecting flight. After my sprint to get the connecting flight, found that no place for my carry on. Had to sit for 3 hours with my back-pack on my lap , it was the most uncomfortable and inconvenient journey with little to no empathy shown by cabin crew in both flights. Another poor show from Air Canada!! Cant help because of lack of options !!

Another poor show from Air Canada!! Cant help because of lack of options !!

Economy middle seat was so narrow that I could not sit back comfortably with passengers on either side of me. Over the 9-hour flight, with my body slightly twisted most of that time, my previously-healthy left knee became very painful, even though I got up to walk multiple times. The knee is still painful 3 weeks later. Otherwise, it was a nice flight, but I was crippled over my entire vacation.

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

Dealing with Air Canada was totally miserable and as a result of their website incompetence, lack of customer support, and total non-responsiveness we could not use this flight. We have made a formal complaint to Air Canada and are waiting to hear back, but if prior experience (more than one hour waits on the telephone with no response) is any guide, we wonder if we will ever hear back at all.

The people are great! The trip to Japan is simply never ending!!! Not the problem of the airlines, though.

We were forced to check in our carryon and were given a green label that said to pick it up when exiting the airplane. We were told by the flight attendant to pick it up at the carrousel instead. We spent more than 40 minutes looking for the carryon which appeared at the wrong carrousel. There was no agent at the united desk for help. There was no entertainment.

Confusing with Air Canada and United flight, it was a hell, no help, rude people there, stressful environment

People were very nice and helpful. But the plane is noisy, and crowded. Seats are too small. Plane was too cold too. Air Canada app is very slow. Couldn't upgrade seats to the next section. Also surprised that basic economy seats were actually standby.

People were very nice and helpful. But the plane is noisy, and crowded. Seats are too small. Plane was too cold too.

Great crew and the plane was very nice! The problem was that we didn’t have WiFi on both of my flights. I found that to be very disappointing today when all the other airlines always have WiFi so I could work or watch a movie.
