The fact that LH and TK do not like each other is a given, but this issue is 100% the fault of TK. LH does not design the poorly functioning M&S backend system that cannot accurately match fare codes and partner mileage earning for *A flights. TK's refusal to addres this known glitch is the true culprit here.

Unfortunately, TK and A3 are the only two programs I could reliably get *G with, and I do not plan on flying A3 more than once or twice in my lifetime. TK is certainly an option for my TATL flights, but their current schedule for LAX leaves a lot to be desired. I am actually more likely to be flying PE than J (*G is basically worthless when flying J, anyway). TK got rid of their PE, but all of the LH PE fares earn well on TK (aside from Swiss, which just launched their product and is absent from M&S).
