Superpoints can be transferred from any account to any other one free of charge and that's why they are heavily traded on aution platforms like ebay and Ricardo in Switzerland and Germany before being transferred into miles (where trading is not allowed anymore).

I myself did that way accumulate over 5 Million miles&more miles in the last 12 months (and my average price per mile is now way below 1 US cent/mile).

From time to time there are promotions to earn extra points on specific articles, and also from time to time the exchange rate Superpoints:miles&more miles was 1:1 in the past (limited time only).

Also, but not cheap, most FrequentFlier programs allow you to buy miles from them (but I really don't recommend this, unless you fast need just a few more miles).
