Nail on the head. Airliners have already moved away from the hub-and-spoke model to a point-to-point model where smaller narrowbodies fly direct from small airport to small airport (E.g. Southwest in the US). They do this specifically because of the increased efficiencies of smaller aircraft. If you can further lower the per passanger cost of small planes, you can make smaller airports more viable, and fly point-to-point from more odd routes. Think Oxford, UK (OXF), to Gothenburg, Sweden (GSE).
