If you are a member of American Express Membership Rewards you can transfer your Membership Rewards points to your Air France Flying Blue account. Usually, 1000 American Express Membership Rewards points equals 1000 Flying Blue Miles.
But for now, on the Flying Blue site (not thru the usual Amex site), there is a 30% transfer bonus to Flying Blue. Instead of the normal 1:1 transfer ratio, when you transfer 1,000 Amex points to Flying Blue, you will end up with 1,300 miles. If you need Air France Flying Blue Miles, consider transferring now.
