FlyingBlue accounts are free and require no mileage balance for award searches. Look for Classic awards. This is very handy for one looking to depart from a U.S. AF or KL gateway. Then search by schedule on delta.com to book online.
One can use ExpertFlyer or Flying Blue to find Business award seats SEA-CDG-PSA as sought by the OP - but perhaps not for the OP's specific date and passenger count.
