It is interesting that I cannot see any AC6614 on AC.com... Those codeshare used to be only slightly more expensive than YYZ-PEK/PVG AC direct and booked into K or L.
I know CA sucks and HU & CX are much better and cheaper options, but I need some status miles....
EVA unfortunately has overnight layover in TPE both ways and OZ doesn't serve YYZ well.
