Departure window
The best time of day to leave IND in June
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 35 points, against 14 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1,178 flights90.0%
- 8am–11am557 flights92.1%
- 11am–2pm744 flights78.5%
- 2pm–5pm695 flights73.4%
- 5pm–8pm799 flights70.6%
- 8pm–5am276 flights56.7%
Scale runs 50% to 100%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 56.7% on time, against 92.1% for the 8am–11am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5am–8am window is the busiest, with 1,178 flights scheduled in it.
Across the week, Tuesday is the strongest day at 85.9% on time and Sunday the weakest at 72.7%. 13 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at IND in June
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 90.4% of the time; American Airlines manages 76.9%. Sample sizes sit next to every figure, because a two-point gap across 627 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Republic Airways | 1,237 | 86.0% | 71 min | 2.99% | A |

Delay causes
What held IND up in June
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 63,000 reported delay minutes.
- 39%Late-arriving aircraft
- 30%National Airspace System
- 29%Carrier
- 3%Extreme weather
- 0%Security
39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 63,000 reported delay minutes here, that single category outweighs weather by 15 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 63,460 reported delay minutes.
Cancellations sit at 1.88% against a national 1.65%, which is ordinary. Diversions add another 0.24%.
7.6% of arrivals land an hour or more late, close to the national 9.7%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
