There are a fair number of connecting flights that this is a good fit for. For example, I fly out of Madison, WI regularly and almost always connect through Chicago, which I believe is right around the 125 mile mark.
Used to regularly take the shortish flight from Boston to Chicago, and then a bus >3x as long to Madison to see family, because the puddlejumper was too expensive or not even running.
