I am *G with OZ but fly mainly SQ as I am now based out of SIN. I have many points from a credit card which are expiring soon.
Which would you recommend I credit the converted credit card miles into:
- OZ (as miles accumulated last for 10 years compared to SQ's 3 years?)
- SQ (as it's cheaper? (uses fewer miles) to redeem as I am based out of SIN)?

I am in no hurry to use the miles and my plan is to use the miles to fly from SIN to Europe or USA.

Thanks!
