(I'm not sure if there's a more appropriate forum for this question ?)

I came across buy and fly! which enables you to redeem points for, amongst other things, flights on SQ, CX, BD etc. You collect points by various means including a Morgan Stanley credit card, cinema tickets and pizza.

Does anyone know if you can only redeem points for SQ flights or do they convert to KF miles ? If the latter, what's the conversion rate ?
