There is no money in Orca as far as I can see. To me the real credits in passenger trade right now are in bulk tourists, who mainly use economy class seats. Luxury cabins are only for sightseers and explorers - good cr/job to be sure - but poor cr/time and by the time an Orca has finished one such mission, a Python or a T7 has made at least 10 times as much shuttling between two or three systems hauling cattle.
Orca could try to stack the explorers. There are often multiple explorer missions to same destination and if they are luxury requirement passengers, three or four 1000 ly jobs could be stacked into Orca. But there are also other class explorers, meaning if Orca stacks 4 "Center of Nebula" jobs, Python stacks 6 and finishes faster.
So I see no real point in Orca as a passenger transport and in my mind it stays as a curiosity at least for now.
