First of all, I am a very loyal AC customer and regularly fly back and forth between Mel and YVR. I was on the inaugural direct flight last year from YVR to MEL and it was an "event". My latest trip was in Premium Economy. I flew YVR/SFO/MEL on Qantas PE and it was fantastic so I was looking forward to MEL/YVR in AC's PE. What a disappointment. Qantas' PE is curtained off from economy and has its own crew. AC is not curtained off and does not have its own crew, it shares with economy and the level of service is no where close to that of Qantas. I don't know why, but AC has the same grumpy crew on the flight from MEL to YVR every time I return to Canada. Flying from YVR to MEL, we seem to have a pleasant crew which makes me glad I booked with AC but the return trip is always a different story. I feel badly for the Aussies who are on the flight, they must wonder why Canadians are so miserable. While I enjoy AC flights in Canada and back and forth to the US, I won't fly them internationally again - there are far better options even if the flights are not direct.
