Thanks for the tip, have not considered Lifemiles before. With a cursory glance though, it seems that TPAC Flex when ticketed in K/L fare code only earn 50%-25%, which is the bulk of our flights. It seems like the best candidate so far is still TK with their 100% earn rate on international K/L in Flex.
