Wow! I started this thread asking the best way to get Krisflyer miles, and I don't know the trick! I'll go for a PM as well, if anyone can send to me please.
Not sure how different I am, but it seems to get good points earn, you need to run your own business so you can use a card to pay your tax and business expenses. However I'm not a business owner these days, just a lowly employee, so all I could do was pay my tax return with the card.
So what action have I taken on this? I did an analysis of my spend each month and what my requirements are (best points earn on my current spending). Seems a lot of utilities etc demand a credit card surcharge, so I'm not paying extra, they can continue to direct debt from a real money account.
I took up the offer on the AMEX PLATINUM EDGE card of no annual fee, and 3 points per dollar for supermarket shopping. At approx $1200 per month, I'll now be getting 2400 more points per month, transfer to KF at 1:1.
I've also opened a CITIBANK SIGNATURE VISA card - Reduced annual fee of $299 (for life if I recall), a sign on bonus of 60K points and 1.5 points per dollar for Aus merchants and a whopping 4 point per dollar for overseas merchants. And Singapore Airlines is an overseas vendor, so... Transfer to KF at 1.5:1. So my minumum KF points earn is now 1 point per dollar.
I calculated quickly on an average month I'll now earn at least 6000 KF points where previously I'd have earned about 3000. I'm now looking at how I can increase my spend through the card... any tips that won't bankrupt me are welcome!
