To be explicit here, because you've got at least one other flight that looks like a codeshare....
For *A, it's the
operating carrier that matters. I'd be shocked if you had a LH-operated flight from MAD-BRU. I suspect that flight is SN-operated, so you need to use SN in the calculator. (You'd also need to use the mapped fare class, but for LH group airlines, they should all map directly, so Y->Y).
