I took Air Canada last month, for the first time. The flight was YYZ
. Nothing to complain about. The check-in line, for both coach and first, were not small, but working fine. The employee at the counter was polite and did my check-in in no time at all, even me being brazilian, which means that she had to spent a little bit more time checking visas.
Before the flight, we have experienced some software trouble with the Embraer 175, delaying our departure in more than one hour. The pilot made speeches in every five minutes, which was very kind and professional.
I was in first class, but I went to a washroom at the end of the plane and could observe that everything was running smoothly. They had alcohol and a very fair meal in first. I didn´t have the chance to see if alcohol was available in coach. As soon as the flight attendant in first finished the delivery of trays and first round of drinks, he went to coach to help the service.
Bottom line, IMO you get a very decent level of service if this flight can be considered standard for Air Canada, regardless of class of service you might prefer. I guess they are on par with a good flight from United and definitely better than American.
Just as a side note, Air Canada is very well respected in Brazil in terms of level of service.
I hope you have a safe and pleasant flight.
