I already have our tickets for a September trip, but I just saw that tix for early September non-stop Boston/CDG are $346 and $425 each way on American Airlines. I also plugged in NY to CDG and saw prices around $420 each way non-stop. Tickets need to be bought by April 10 for travel thru October. I did not check summer prices. If you're planning a fall trip, this might be worth looking into. Happy travels!
