Perhaps you should join AFKL Flying Blue instead, unless you are more interested into the upgrades into domestic "in the front of the airplane" class on DL which is no longer a benefit.

There are so few FB Platinums left today that your chances of getting TATL op ups on KL metal are now greatly increased. Also, there is no problem in finding premium award travel easily online with the booking tool, often offered at discounts of 50% off of the standard mileage rates on selected flights. For example, now AMS-MEX RT in biz class for 50k miles.
