Now that CZ is going to operate WUH-SFO non-stop on 787 [1], as my parents live in WUH and I live around SFO, I'm considering stock some miles for them to visit me.

I don't really fly SkyTeam, so what's the best program I can stock by credit card spend or transferring SPG points to redeem CZ business or premium economy tickets? For credit cards I know there's Delta and Flying Blue (transfer partner of Citi ThankYou points), but I can't find flying blue award chart and have no idea whether it's easy to get CZ business or premium economy tickets from them.
