Ok, its much easier to use the real example. I assume this is what the OP is wanting to book as a Status Run.
Booking QF2404 as BNE-BLT and then booking BLT-BNE as the combination of QF2404 BLT-EMD and QF2409 EMD-BNE.
Now its the same flight number and aircraft that operates QF2404 as BNE-BLT-EMD. But he is hoping to book it as BNE-BLT and then BLT-BNE (via EMD) and earn 3 x 10 Status Credits.
According to the published rules of the QF FF program (as posted by serfty on the same discussion on AFF), even if its on one ticket, the member is only entitiled to the through flight BNE-EMD and EMD-BNE points and status credits.
However, it is quite possible that the programming logic behind the QF FF system will actually credit it as BNE-BLT, BLT-EMD and EMD-BNE.
BUT if it does not automatically post that way, it should be understood that there is no entitlement for the 3 sectors according to the rules and so you may not be able to claim the extra sector through manual processes.
Of course if he stopped in BLT overnight there would be no issue.
