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.

PBI to IAH questions
- What time of day is best to fly PBI to IAH?
- Before 9 AM: 96% of flights arrived on time, against 75% 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 PBI to IAH?
- United, with a season-adjusted 84% chance of operating and arriving on time over 430 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 (68% on time); the best was April (86%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
