Your reply is perhaps not entirely accurate. In practice, an RTW ticket from Aegean is actually often rather less miles than the standardised equivalent from other *G airlines. In the case of LH, for example, an RTW ticket in C requires a fixed 325,000 miles. If you take a routing like Germany - Morocco - Turkey - India - Japan - US - Spain - Germany, only 273,000 miles are required by Aegean. Basically, you construct your own RTW fare by adding together the mileage for each sector.
