So after reading this post I checked my FRA-IST-MUC flights in April. I bought them on CO's website and it shows on the "View Current Reservation" page that I only get 50% EQM for the two flights. I noticed on CO's Lufthansa partners page that "S" fare class within Europe receives 100% EQM. I viewed Lufthansa's website and it states that I would receive 750 miles (not sure if it is EQM). I am not sure which information is correct: 50% EQM, 100% EQM or 750 miles. I may have to do the United Mileage Plus trick as stated above. It is about 1050 EQM that I will be missing if it at 50% EQM.
