I'm a fan of Qantas service to SYD having flown QF six times in the past year. In September and December my organization's travel department booked me on Air Canada on trips to HKG and SYD. I must say that I was very impressed. The AC seats are lie-flat in a herringbone pattern, which gives all J class passengers direct access an aisle -- you won't have to climb over a fellow passenger like I had to do in UA's new J product from SYD to SFO when I was stuck in a window seat. The seats are also a true-flat product. I found the departure time from YVR convenient. The food was quite good with the exception of the bread rolls (it's an AC mystery to me why their bread products are so poor). A good selection of snacks is available at all times in the J class galley. I have found the AC flight attendants based in YVR far superior in temperament to YUL-based crew. The on-demand entertainment system is very good but not as good as QF or SQ. There are always some good French-language (but subtitled) Quebec films that can be an enjoyable surprise for non-francophones willing to experiment. All in all, I think that AC to SYD is a superior service across the Pacific on 777 equipment.
