Thanks for explaining .... now I understand. In order to get a free flight (<+ $350) I have to spend 16,667 $$$ + 50% =25,000 points. Not bad. Also no fee. But not for me ... I collect Starwood and for $20,000 I get 25,000 miles, sometimes more. I also have Chase BA and Barclays M&M. I pay a fee, but got 20,000+ miles bonus each.
Anyway, thanks again^
