If I fly STR-FRA-ZRH and back, the ticket in C is approx. 530 € and I earn 8,750 miles with Exec bonus.
Are there similar routings which earn more miles out of FRA, CGN or STR? (probably with more transfers?)
I looked into FRA-SAN or FRA-LAX on United for a weekend in April, this would earn approx. 15,000 miles incl. Exec bonus for 530 €, but because of the time change it is pretty inconvenient in Eco.
