If you missed the chance to switch to the Amex Platinum from Brussels Airlines Miles & More Amex in the summer, now might be a great time to reconsider.
Amex is currently running a generous promotion, providing a signup bonus of 150,000 points for new Platinum applications and 60,000 points for Gold applications until November 28.
This is quite an attractive offer, especially when compared to the historical promotions Amex has previously extended to Belgian customers...

I wrote a little post about this whoever's interested:
