CVG across all twelve months

These figures cover 3,105 departures from Cincinnati/Northern Kentucky International in March 2026. 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

March next to CVG's other months

Against CVG's own year, March ran 3 points worse than the twelve-month rate of 78.8%, which makes it number ten of twelve months, best first. Either side of it, February ran 77.8% on time and April 83.6%, 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 March

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 24 points, against about a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am856 flights86.6%
  • 8am–11am571 flights76.3%
  • 11am–2pm446 flights70.9%
  • 2pm–5pm537 flights74.8%
  • 5pm–8pm562 flights62.3%
  • 8pm–5am133 flights71.5%

Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.

The 5pm–8pm window is where this operation falls apart: 62.3% on time, against 86.6% for the 5am–8am 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 856 flights scheduled in it.

Across the week, Tuesday is the strongest day at 79.7% on time and Saturday the weakest at 71.5%. 8 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at CVG in March

The three carriers here are closely matched: about a point separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

Delay causes

What held CVG up in March

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 66,000 reported delay minutes.

  • Late-arriving aircraft
    32%
  • Carrier
    31%
  • National Airspace System
    29%
  • Extreme weather
    8%
  • Security
    1%

The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 86.6% on time here. The split is drawn from 66,279 reported delay minutes.

Cancellations run at 2.80%, against 2.90% nationally. That is roughly one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.0% of arrivals land a full hour or more behind schedule, against 9.5% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

What to do with this

Flying from CVG in March

For a March trip through CVG: plan on this being one of the airport's harder months. The 5am–8am departures held up best at 86.6% on time, and with 10.0% of arrivals an hour or more late, a connection here deserves more slack than the same trip in September would.
