Flying Blue (Air France & KLM) - best FFP for reward tickets with wife and one kid ?

I don't know if it's the best forum for this question. Could be. Flying Blue do nothing. What about other FFP in Sky Team ? Miles and more offers 50% miles less for companion and 25% less for kid (2-11) In C, 3 reward tickets, flying blue needs ... 480 000 from Europe to Asia (or South America). Miles and more asks for 270 000 . No comment. Does similar or better ones exist ?
thx for help :) :) :o

Im not sure on the others, but why not use the miles for those web@ward things? 50% of normal charge...

I thought about, 240 000 miles with Flying blue, but if for one people the risk is limited, for 3, ... you cannot cancel these tickets, and I'm not so ready to lose 240 000 miles, considering the high level of kindness of AF/FB customer care....there is no hope to get them back. (Ok, it's the rules).
One thing more : I don't know if you noticed that : the most of 50% promotion are done on KL and not on AF. Second thing, in average *A taxes are much more low than AF ones. (3 RT tickets in business class = more than 1000 euros). This is more than 50% of a payed Z fare ...) ok... it looks complicated in anyway.
* and the final destination must be in the list of promotions ...
