Question on hub

I'm making some routes from my hub airport to very cheap airport.
But I don't get the connecting factors.
I thought I can always get the connecting factors for the routes from/to the hub airport.
Are there some cases I cannot get the connecting passengers?
I would like to appreciate your answer, thank you

I guess it would also depend on the demand right?

Well, if there is more than enough demand for that flight between city pairs, you will not see connecting traffic. Of course, once you add more frequency, connecting traffic will grow as there is more flights and more demand been create, and while your hub grows with other routes, you can grow that.

The total load factor (=direct passengers because I got no connecting passengers) on those routes is less than 100% like 90%, 80%,sometimes 50...

But I see. I'll focus on the frequency to grow those routes.

Thank you for your help, two of you!
