I was able to price out an award ticket in J saver for 120k miles doing LAX-ICN(open jaw), PVG-BCN(stop), BCN-RDU. I'd have to pay for a one-way from ICN-PVG and for my travels within Europe. It seems according to the 2 open jaw + 1 stopover rule I might be able to save by adding CDG-RDU instead?

Are there any paid alternatives that could be reasonable? I'm 5k miles away from reaching delta gold and have ~13k miles on United, not sure if I can MR since I will be based in PVG from August on. Just pricing stuff on on kayak I got around 2500-3000.
