Historical odds, not a guarantee. Built from the US DOT Bureau of Transportation Statistics on-time reports (Jun 2025 to May 2026), FAA ground stop and delay program advisories, and 20 years of airport weather observations.

FAT to SFO questions

- Which airline is most on time from FAT to SFO?
- SkyWest, with a season-adjusted 69% chance of operating and arriving on time over 1,306 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.

- May (67% on time); the best was June (86%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
