Unclear as added miles for EWR-FRA-KBP on LH.
Added in total:
EWR-FRA Continental 8838L/Lufthansa 0403L 1,935 miles (that is only 50 %)
For FRA-KBP didn't add in general.
For KBP-MUC-JFK too on LH, too on the L tariff added 100 % of miles.
It is United were mistaken or I don't understand something? There should be 100 % of miles for LH L-class
