I was looking for AUS/CDG award seats a week ago. DL and CO had nothing at all, but NW and AF offered quite a few options. My friends from Phoenix are going PHX/MEX/CDG and back on AM on DL miles. They also could have hooked up with AF in MEX. Some of the agents really don't know how to piece an award ticket together. Have you looked at AF through SFO, LAX, SEA, IAD, or NW through DTW or MSP? My TATL flight is going out of IAH on AF and I am returning through MSP on NW. I don't know much about KLM routing, but I know you can use miles to CDG on them going through AMS.
Good luck and post back your results.
