These figures cover 946 flights between July 2025 and June 2026. Beyond the headline rate, 10.2% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Carrier by carrier

United against every carrier on CVG to ORD

United flew 946 of the 4,630 flights on CVG to ORD, about 20% of it. Its 68.5% on time is 2 points worse than the route as a whole, which runs 70.2%. Ranked by on-time rate it is number four of six carriers on the route, where the range runs from Republic at 77.8% to American at 41.8%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The choice of carrier is not cosmetic here. Republic Airways arrives on time 77.8% of the time; SkyWest Airlines manages 58.6%. Sample sizes sit next to every figure, because a two-point gap across 895 flights means less than a ten-point one.

Departure window

When United runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 33 points, against 19 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am350 flights77.0%
  • 8am–11am62 flights80.0%
  • 11am–2pm2 flights
  • 2pm–5pm248 flights77.6%
  • 5pm–8pm281 flights47.3%
  • 8pm–5am3 flights

Scale runs 40% to 85%. Rows with fewer than 30 flights show a dash.

The 5pm–8pm window is where this operation falls apart: 47.3% on time, against 80.0% 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 350 flights scheduled in it.

Darker means more delays. Figures are on-time percentages.April best, December worst

December is the weak month at 52.5% on time, against 84.4% in April. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. September was the busiest month here, with 118 flights.

Across the week, Thursday is the strongest day at 73.4% on time and Saturday the weakest at 63.6%. 10 points is a smaller lever than departure hour, but it is free.

Delay causes

Why United runs late on this route

One category carries most of the weight here. National Airspace System accounts for 53% of the 22,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

  • National Airspace System
    53%
  • Late-arriving aircraft
    23%
  • Carrier
    16%
  • Extreme weather
    8%

53% 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 11,000 minutes out of 22,000, against a national NAS share of 21%. The split is drawn from 21,531 reported delay minutes.

Cancellations sit at 2.43% against a national 1.81%, which is ordinary. Diversions add another 0.11%.

Connections and stage length

What a delay here costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.2% of arrivals land a full hour or more behind schedule, against 8.1% 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.

At 264 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 8am–11am window matters as much as it does.

The return leg is a different operation and performs like one: it runs 72.4% on time across 945 flights, 4 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 4 points of difference.

One caution: this is a thin sample. 946 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.

What to do with this

Booking United on CVG to ORD

Put together: treat all of this as provisional. 946 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 68.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 922 completed flights over 12 months sit behind that.
