I would prefer to not do 2 connections to get home which is why I haven't looked out of Vancouver.
I searched aeroplan earlier for end of calendar and there's nothing reasonable in biz. It had EVA but it was mixed with the biz being from Shanghai and economy to Seattle.
We're not flexible on dates, this trip already has me taking off almost 3 weeks, I would rather be back home on Sat than Sun, but that would be the only flexible bit. ABD finishes in Shanghai so it makes most sense to fly from there. There also doesn't seem to be much partner availability that makes it to aeroplan, and now that ANA allows OW booking it'll be worse, it's competing with people trying to get home from Japan.
I'll explore all of my options at 360 days because I can't book dl that early. And maybe it really is a matter of being on when they drop vs just searching end of calendar but even economy wasn't pulling up for most of what I looked for this afternoon.
There's issues with sky team partners not getting as many awards or it's very sporadic. China just seems more difficult than Japan and with the ABD we're stuck with dates etc.
Almost makes me want to look into the emirates flight I saw through Dubai

So far out of the way.
