I was on one flight about 5 or 6 years ago (I forget which UA express carrier it was) that operated FAR-FFM-MSP. If I'm not mistaken, they did label the FFM stop as a "flag" stop (being that they only stoped if the're were scheduled passangers there that day). This route doesn't run any longer due to insufficent demand at FFM. Now, every one at or near FFM either drives the hour 70 minutes to FAR or the 4 hours to MSP.
