I was "online chatting" with her for nearly an hour as she made various attempts to find out why the calculator on the promo page did not return DSC for BNE-NTL. She typed that she rang quite a few resources including the Loyalty team and finally came back with this "exclusion" reason. Not sure who her source for this final "reason" was but she typed that it's because BNE-NTL is operated by Sunstate. Other Qantaslink services however do earn DSC. Still not sure what makes Sunstate such a pariah in this promo.
