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.

- August (70% on time); the best was October (85%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
