I guess One popular route for People up north is is YVR-SYD via HK on CX. It's cheap and cost effective. By having AC direct, I wonder if this pose any competition but I certain hope so.

It's interesting, YVR->SYD on CX costs merely CDN$1700 during peak, but SYD->YVR on CX costs costs nearly AUD$2800 during peak. Just did a quick check for AC and it's showing CDN$2000 for SYD-YVR.
