The range is important because historically, small jets had comparatively short ranges. The pattern used to be to use small jets as feeders to major hubs. The large jets would fly between the major hubs. Now, with small jets having greater range, you can send flights direct bypassing the major hub. There is not enough traffic on the route to warrant a large jet, however, so smaller jets with the same range are preferred.
