Don't use those services unless you have to. For August almost every day has either *A (mainly LH but some directs on UA) or OW (mainly BA which will carry fuel surcharges) J availability from NYC-Paris.

Here's an example of what you could do:

13th August EWR-CDG UA J - 115k for 2 (top up your UA account by transferring some extra points from chase)
19th August ORY-JFK BA(open skies) J - 100k BA or 115k UA + $300 tax each
