to search for availabilty, I also know there is an unoffcial search engine which allows you to search for awards on NW a week at a time I believe but I don't have the URL.

Also it would help if you post your info (Orgin/Destination(S!) favorable dates. You might have a chance if you are Extremly flexible. I would also urge you to consider other destinations besides Europe. If you have elite status that might help open some availability up(I know it does on DL and I think CO) I don't know how many you miles you have but Continental.com is showing decent First Class availability for 4 people in August(EWR-CDG), sure beats using double miles on a rulebuster coach ticket.
