As far as I remember reading here, FB does *NOT* offer 100% EQM on all of their fares. I believe KLM N & E classes still only offer 25 or 50% EQM's. Of course, all fare classes on KLM offer 100% EQM in Northwest WP.

Also, though not 100% certain, if you are living in the US, you can't open an FB account - you need to open a WorldPerks account. Likewise, if you're living in Europe, it's the other way around. This may not be accurate information anymore - but this used to be the case.

Finally, the lower coach classes on CO only earn 50% in NW WP. So if you're going to keep your account at NW but fly CO, you have to book the higher fare classes to get 100% EQM.
