great flights both ways on time both ways.staff(ladies) where great at check-in.

We travelled from London to Halifax. Customer service was excellent.fron the day we booked until arriving. The gate was only a short frombthe waiting area and walk Boarding was efficiently handled and plane took off on time. The service on the plane was very good. Fool an acceptable drandard Only downside was that the legroom was tight for anybody just over 6ft tall and am usually able to travel without difficulty. I will definitely fly with Air Canada again but next time pay for extr space.

Was disappointed when landing in Canada was made to wait for over 1 hour with several other parents and babies for our strollers . The expectation was that the gate checked strollers would be there when exiting aircraft. This was not the case we were told to walk to a point and wait for them . After being left there and not being updated we were met with very hostile and rude air canada staff . There where no apologies or understanding even though all the children where very uncomfortable and the parents very frustrated as you can imagine . Instead the air canada staff at the airport where very rude and made an already frustrating situation much worse instead of trying to assure the parents that that were making effort to fix the situation. One gentleman in particular was very rude to some parents telling them to move when they were simply seeking information. He made the other parents including myself feel very uncomfortable. He also told a gentleman he was capturing images of everyones boarding pass when this was untrue as he was only taking a photo of the gentleman pass which was strange.

It was good, seating was a little tight apart from that all was well.

No entertainment. Luckily I was the only person in that row. Small seating

The Air Canada experience wasn’t bad per se. It was the Toronto airport experience that was truly horrific. Terrible crowd, control, poor signage, and power, hungry security people who felt the need to tear open gifts in a hasty and careless fashion, causing damage to my items because they don’t know how to read a damn x-ray. On top of that the attitude was completely disrespectful and callous. I left feeling completely violated.

Four hour delay, no communication and multiple reasons for delay. Rude counter person even though I had a business class ticket. Bad experience all around.

I really didn't flight from Toronto to Sydney Because my flight was cancelled for the snow But you guys help me lot and put me in the flight from Toronto to Halifax I give you at 10/10 because was really good Just I had to drive 4 hours to be home

Very little leg room and the flight was fully booked. Had to leave my carry on luggage a fair way from my actual assigned seat.

I wanted to change the dates of my flight and was not able to do. Had to cancel it without getting any refund. Bad customer support and worst experience ever.
