Horrible! Rude flight attendant, barely any service on such a long flight. I wouldn't recommend Air Canada to anyone.

Horrible! Rude flight attendant, barely any service on such a long flight. I wouldn't recommend Air Canada to anyone.

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 stag were helpful, kind and liked the passengers. The plane was pristinely clean! Great flight!

The staff was great and made the long trip easy peasy!

The free Wi-fi for Aeroplan members was a great touch. The time passed quickly. I found the seats seemed a little closer together than I remember. Not Air Canada's fault, but we were about 20 minutes late landing because the airport was too busy. We had to circle around for a while. The boarding and disembarking went very smoothly.

I liked the behaviour of the crew members.The flight was good.

Multiple change of the gates at Pearson, delayed flight was extremely uncomfortable.

Never made this leg of the flight since we rebooked through United instead. Did not make it to immigration/US custom due to the delay. Had to spend the night on our own dime in Toronto

Experienced flight cancelations and delays in 5 days. They seem pretty common to AC. Experienced with one of AC's check-in agents at the counter of a big liar. She lied and acted (yes like acting in a movie) that an early flight was fully booked and refused to rebook me, but my flight was delayed two hours so I could not make my connection. Later, I got help at the gate to switch the early flight (Big thanks to that agent). Ater boading, I found the early flight was only 2/3 full meaning there was almost one vacant seat in a 3-person seater, and multiple empty 3-seaters. AC is wired that it is filled with good and bad employees. BTW, AC employees seem never smile, or they don't know how.

Seating for almost 3 hours in the plan before aircraft takeoff. Very exhausted .
