CVG across all twelve months

These figures cover 2,941 departures from Cincinnati/Northern Kentucky International in October 2025. On time means an arrival less than 15 minutes after the scheduled gate time, the DOT's threshold, and the national comparison uses every US departure in the same month rather than the whole year.

Against the year

October next to CVG's other months

Against CVG's own year, October ran 2 points better than the twelve-month rate of 78.8%, which makes it number five of twelve months, best first. Cancellations were unusually low for CVG in October, at 0.48% against 1.91% across the year. Either side of it, September ran 85.4% on time and November 82.7%, so a trip moved by a few weeks would have landed in a better stretch.

Departure window

The best time of day to leave CVG in October

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 23 points, against 14 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am788 flights89.0%
8am–11am414 flights87.6%
11am–2pm521 flights81.3%
2pm–5pm488 flights77.4%
5pm–8pm597 flights73.1%
8pm–5am133 flights65.9%

Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 89.0% of the time, against 65.9% for the overnight window. That is 23 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 788 flights scheduled in it.

Across the week, Saturday is the strongest day at 86.3% on time and Sunday the weakest at 74.3%. 12 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at CVG in October

The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 89.0% of the time; Republic Airways manages 74.6%. Sample sizes sit next to every figure, because a two-point gap across 491 flights means less than a ten-point one.

Delay causes

What held CVG up in October

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 33,000 reported delay minutes.

National Airspace System
35%
Carrier
33%
Late-arriving aircraft
30%
Extreme weather
2%

35% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 12,000 minutes out of 33,000, against a national NAS share of 23%. The split is drawn from 33,167 reported delay minutes.

Cancellations are rare at 0.48%, below the national 0.53% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

5.8% of arrivals land an hour or more late, close to the national 6.3%. 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 about an hour, which a normal layover absorbs.
