Trying to go SEA-CDG next year on an AF award ticket in Affaires using AS miles.

The inventory for AF award seats SEA-CDG on the non-stop has all but dried up. Occasionally you may see one seat 330 days out. ( I need 2) My alternatives are:

LAX ( good inventory)
SFO ( also hard to come by)
ORD (good inventory)

I have time to hunt for the the SEA-CDG nonstop...but if that doesn't materialize is there a preference as to which city I should book based also on what AS first saver awards I can get to the departing city.AS Saver award inventory has also dried up and not as easy to get as it use to be.
