- SkyWest, with a season-adjusted 84% chance of operating and arriving on time over 302 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.
- What is the worst month for delays on DEN to ATY?
- August (68% on time); the best was November (97%), from one year of data, so one bad storm season can move a month.
- 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.
