I believe (and feel free to correct me) that the Timmy can't make the run from KBL to BZN in one hop because the runway at KBL isn't long enough? It can go direct outbound, but not on the return trip.
What would the cost be to extend the runway v the cost of flying the extra hours it takes to fly to Dubai, change crews and then fly onto BZN?
Is there a practical reason that the runway can't be extended at KBL?
How long would it take to make up the investment of building it?
Just food for thought...
