Hi chornedsnorkack. I think a fast 150 seater for regional services is A320/737 territory. I think the C-series is a bit smaller and probably longer range. Not a typical short haul people mover.
C130 has maximum seat capacity of 145 at 5 abreast, MTOW up to 63 tons or so - bigger than A318, and closer to A319. The 64 ton version has 5000 km range - there is a version with 3300 km range and a lower MTOW.
So, C150 could be an option.
Is that so ? Anyone a picture of that? I remember the P3C had them, but obviously not only for fun / admosphere..
Well...

In the tail, above the engines.
Hong Kong to Seoul is best served by a 747 or an A380. Max capacity counts on this high density route.
747, with the exception of 747SR models, is too much of a plane for the range. Ditto about A380-800. Cathay Pacific said that they will buy A380 if Airbus increases MTOW OR stretches the plane. So, CX could use an Airbus 380-900SR in addition to their B777-300 non-ER...
