The In-flight service at Air Canada is inconsistent. There are lots of F/A's that do a fantastic job, and a handful that are completely useless.
There are those, particularly on overseas, whose only motivation is to see how fast they can hit the bunk and catch up on their sleep.
Overall I do believe that the service (when done by the book) is very good.
The larger problem at Air Canada is the strength of the F/A Union, CUPE. F/A's live in a world of impunity and can get away with (almost) anything.
Couple that with the "socialist agenda" of Canada and it is...not good.
For our - out of country - friends you have to understand how upside down this place is.
It is the "Air Canada Component" of CUPE that has filed a "Human Rights Complaint" that F/A's and Pilots are;
"Work of Equal Value"
...and we should be paid the same!
Management need to resort to "ghost riders" and get a handle on the offenders. Then they need to have the guts to do something about it.
