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. Covers US airlines that report to the DOT; schedules are flights operated recently, so confirm times when you book. ATIS Alerts is not affiliated with any airline.

- Southwest, with a season-adjusted 85% chance of operating and arriving on time over 516 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.

- June (80% on time); the best was September (93%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
