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.

BDL to MIA questions
- What time of day is best to fly BDL to MIA?
- Before 9 AM: 91% of flights arrived on time, against 84% for departures 3 to 6 PM. Later flights inherit delays from earlier ones, so the first departures of the day usually run best.
- Which airline is most on time from BDL to MIA?
- American, with a season-adjusted 89% chance of operating and arriving on time over 396 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.

- January (75% on time); the best was September (97%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
