The flights were on time and I appreciated that the cabin crew helped passengers with overhead luggage - finding space etc - despite not being paid. Apparently their wages don’t start until takeoff. This makes no sense whatsoever.

The flights were on time and I appreciated that the cabin crew helped passengers with overhead luggage - finding space etc - despite not being paid. Apparently their wages don’t start until takeoff. This makes no sense whatsoever.

I didn’t have any food but my Prosecco hit the spot. We left on time and the crew was friendly.

I wasn’t able to book or pay for a seat and they forgot to check me in for my third flight so I spent 24 hours in Toronto waiting for another one.

I like the wider seats, Plus lots of legroom, Lacking entertainment, no tv or screen to play with

The keg from Edmonton to Toronto My wife found it very cold. Other than that great flight.

Flight itself good .Landing at terminal3 and connections to terminal1,it is connections nightmare,specially for disable person

The seats very Uncomfortable, no meal and no entertainment for a 4Hours flight. Smooth Flight, Great Take off and landing. Superb crew!

It was good, flight was on time, boarding was smooth and done in zones, food was good too but there was no form of entertainment. Luggage’s were intact. So an overall good flight

Our seats that I had paid extra for near the front of the aircraft were no longer available on this replacement aircraft. We were told we either had to accept the new replacement seats in row 27 near the back in seats E and B, no longer together, or sit in the very back in row 30 squeezed into E and F seats that do not recline or have trays that provide a flat platform for a refreshment. This is not what I had expected. However, again your flight crew did the best they could given the circumstances.

Not a tonne of food for purchase items for early morning.

Delays after delays only to announce we don't know how long it will take

Flight delay due to staff shortage. No snack or drinks served. Toilets had water collecting on the floor.

Flight was delayed due to crew/co-pilot change over delay and Pearson scheduling issue. Flight didn't leave until 20:05 which was 15 minutes before it was supposed to land in YYZ.

Not great. Missed my connection flight, due to AC issue. We were sitting on the tarmac for 90 mins before taking off.

Air Canada was fine but air Canada rouge and air Canada express was terrible with luggage delays. First flight was cancelled so my luggage did not make it to my destination with me. The second flight returning not sure why but my luggage did not make it on my connecting flight. Overall terrible with handling luggage.

Comfortable seats with good leg room. But not screens on seat backs.

Air traffic delay meant boarding started, then plane was evacuated and passengers sent back to the terminal for 1 hour. Very little information shared.

Had to cancel the flight because there was a 14 hour layover before the flight. Unacceptable.

The flight is very short, may be a little snack can be offered

They canceled my flight last minute, no hotel provided and they rescheduled Sunday night, hope they refunded some money
