Update for those interested. It's somewhat difficult to find the Oneworld award chart but like many other posters already said, there has been a massive devaluation after the transition to Multiplus. The chart is now region based rather than distance based and is here: https://www.latam.com/content/dam/LA...-puntos-en.pdf

I had to call Latam's US service center to try to book my Oneworld award on CX and found out some interesting things as the agent was trying to help me book. The prices in the award chart are one way prices so a North America-North America award like LAX-ORD on AA priced out as 50k r/t when I asked the agent to try. However, some good news - you can now book a one way for Oneworld awards. LAX-ORD by itself priced out at 25k plus nominal taxes.

For whatever reason, the agent was unable to price out my PVG-HKG award request in his system. He could see the flight I wanted but when he requested it, it wouldn't confirm and could not give him a total price in Multiplus points and taxes. The agent said he would escalate the issue and provided me a case number for follow up. As an aside, he was able to price out itineraries involving CX flights as long as some part of the itinerary touched the Americas so he didn't know if that was a stipulation. Still need to burn these remaining Multiplus points so to be continued...
