I see that you are KF Silver. To get to Gold you will need 50000miles.
If you want to get *A Gold, why not try to accrue on AC Aeroplan? They only need 35000 miles to become *A gold. The earning power is the same LH Z class 125% miles.
If you are looking for miles. Then LH M&M and BMI Diamond Club will be able to earn 200% miles on LH Z class.
The conclusion is, Krisflyer program is not good and it will be better for you to dump it as early as possible.
