LH mileage calculator shows 8784 miles (including Exec bonus) earned on M&M in L class, which comes out to just under 6cpm. This will be less without status and I am not sure how the cpm works out on other airlines FFP.

Definitely worth posting as it is a cheap fare for LH to South America, but but maybe it belongs in the Great Deals between City Pairs thread(?). Wherever it belongs, thanks for posting and bringing it up!
