DEN to IND questions
- What time of day is best to fly DEN to IND?
- Before 9 AM: 90% of flights arrived on time, against 61% 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 DEN to IND?
- Frontier, with a season-adjusted 81% chance of operating and arriving on time over 285 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.

- July (65% on time); the best was November (82%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
