I purchased 1,000,000 miles, I didn't achieve this by turn-over.

DBS Altitude Card has a very good ratio, Citibank PremierMiles as well. Don't use the AMEX KF Card.

hi! i saw that you managed to get 1,000,000 miles from HSBC. May i ask which credit card did you use? I am planning a big purchase in Sept, need to pay about $40,000+. Am currently using the Premiermiles & Amex KF Card. Not sure if these have the highest mileage earning rate? Thanks for your advice!
