Can't book SCL - ZRH with AC?

Hey!

I've been a lurker here for ages, but never posted. I'm trying to fly SCL to ZRH this summer with Swiss, which I know they do (on a codeshare with LAN via Sao Paolo) but whenever I put it in the booking planner the website tells me this isn't a valid Aeroplan itinerary. Am I doing something wrong, or am I flat out not allowed to go from South America to Europe on Aeroplan points?


Also a related note, I can't do YVR -> SCL -> ZRH -> YVR as a mini RTW, can I?

Thanks in advance for the help!
