Be aware that EK has oviously changed the rules for calculating the "triple" from the old days..kind of cheating, I think!
The offer applies to "base miles". In the old days base mile were calculated as the miles pertaining to your class of flying, minus any status benefits. This is what i assumed to continue when i tried kind of a status run from Germany last year with a double miles offer. Bad idea! Different from previously, the "base miles" were taken to be the cheapest economy saver miles. So in the overall calculation, it shows the eco saver miles (base miles) being multiplied by two plus a business class mark up (not being multiplied at all). So the overall gain of this promotion was very limited..and i gave up going for status again with EK.
