Why not go for services that have bot One Stop Destinations and Hub Spoke.Airline connections as follows:

Town A-City A- City B- Town B (Change of flights)

Town A-Town B- Town C (No Change)

This could add alliance partnerships as well. Say 

Airline A from Town A- City A (Hub of Airline A or Alliance Partner )-Town B 

Revenue could be shared on basis of miles or tickets sold.

Small airliners can get increased wealth and major Airlines get  more PAX on hyper competitive routes.
