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.

BZN to SEA questions
- What time of day is best to fly BZN to SEA?
- Before 9 AM: 92% of flights arrived on time, against 67% for departures 6 to 9 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 BZN to SEA?
- SkyWest, with a season-adjusted 86% chance of operating and arriving on time over 860 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 (75% on time); the best was November (91%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
