Departure window
The best time of day to leave CVG in June
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 25 points, against 16 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am910 flights86.3%
- 8am–11am387 flights88.7%
- 11am–2pm551 flights77.3%
- 2pm–5pm572 flights72.3%
- 5pm–8pm492 flights64.0%
- 8pm–5am217 flights67.6%
Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 64.0% on time, against 88.7% 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 910 flights scheduled in it.
Across the week, Tuesday is the strongest day at 85.8% on time and Thursday the weakest at 70.4%. 15 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at CVG in June
The choice of carrier is not cosmetic here. Republic Airways arrives on time 84.3% of the time; Allegiant Air manages 68.8%. Sample sizes sit next to every figure, because a two-point gap across 411 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Delta Air Lines | 690 | 83.9% | 72 min | 0.43% | B+ |

Delay causes
What held CVG 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 57,000 reported delay minutes.
- 39%Late-arriving aircraft
- 28%Carrier
- 25%National Airspace System
- 7%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 57,000 reported delay minutes here, that single category outweighs weather by 6 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 56,855 reported delay minutes.
Cancellations sit at 1.57% against a national 1.65%, which is ordinary. Diversions add another 0.42%.
8.7% 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 an hour and a half, which a normal layover absorbs.
