in the U.S. at least, it isn’t all that uncommon to find turnaround flights between the airline’s main hub(s) and outstations that carry the same number for both segments ... most of my experience is with DL, where most of these flights are actually operated by their regional affiliates like GoJet, Endeavor, or SkyWest
