IND to DCA questions
- What time of day is best to fly IND to DCA?
- Before 9 AM: 86% of flights arrived on time, against 52% for departures noon to 3 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 IND to DCA?
- Republic, with a season-adjusted 72% chance of operating and arriving on time over 1,801 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.

- December (75% on time); the best was October (87%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
