Which airline is most on time from DFW to SAT?: SkyWest, with a season-adjusted 77% chance of operating and arriving on time over 384 flights. The adjustment compares each airline with what the route did in the months it flew, so a carrier that skipped a stormy month gets no free credit.

Is this a prediction for my flight?: No. These are historical odds from the US DOT on-time reports, FAA advisories and airport weather records. Check your flight status and the FAA delay board on the day you fly.
