GRR to DTW questions
- What time of day is best to fly GRR to DTW?
- Before 9 AM: 82% of flights arrived on time, against 70% 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 GRR to DTW?
- Republic, with a season-adjusted 80% chance of operating and arriving on time over 38 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 (68% on time); the best was October (90%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
