C class will give you 200% points. Assuming you start as a general member with no points;
HAM-MUC
MUC-IAD
IAD-MIA
MIA-DEN
DEN-LAX
LAX-ORD
ORD-YVR
YVR-ICN
ICN-NRT
Will get you ~35K to FTL. The rest of the trip, with COS and Executive bonus will give you ~50k, so your total of ~85k points will have you short of the 100k you would need as a non German resident or 130k needed as German resident.
