Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Republic Airways.

Republic on CVG to ORD carries a cancellation problem, not just a delay problem: 3.5% of scheduled flights never operate, against 1.8% nationally. Of the ones that do fly, close to three flights in four arrive on time, worth a B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 1,346 flights. The strongest carrier on the route with a full sample, Envoy Air, flew 1,338 at 72.8% on time.

The US average over the same twelve months is 77.6%, so there is little to separate Republic on CVG to ORD from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 1,346 flights between July 2025 and June 2026. Beyond the headline rate, 9.0% 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

Republic against every carrier on CVG to ORD

Republic flew 1,346 of the 4,630 flights on CVG to ORD, about 29% of it. Its 77.8% on time is 8 points better than the route as a whole, which runs 70.2%. Ranked by on-time rate it is first 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. Envoy Air arrives on time 72.8% 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.

SkyWest Airlines cancels 5.7% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Departure window

When Republic runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 44 points, against 14 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am49 flights95.9%
  • 8am–11am207 flights75.6%
  • 11am–2pm503 flights80.5%
  • 2pm–5pm355 flights77.8%
  • 5pm–8pm184 flights74.4%
  • 8pm–5am48 flights52.3%

Scale runs 45% to 100%. Rows with fewer than 30 flights show a dash.

The 8pm–5am window is where this operation falls apart: 52.3% on time, against 95.9% 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 11am–2pm window is the busiest, with 503 flights scheduled in it.

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

December is the weak month at 60.6% on time, against 88.1% in September. 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. July was the busiest month here, with 178 flights.

Across the week, Tuesday is the strongest day at 82.0% on time and Sunday the weakest at 70.6%. 11 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Republic runs late on this route

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 23,000 reported delay minutes.

  • National Airspace System
    41%
  • Late-arriving aircraft
    37%
  • Carrier
    14%
  • Extreme weather
    8%

37% 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 23,000 reported delay minutes here, that single category outweighs weather by 5 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 23,038 reported delay minutes.

41% 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 9,335 minutes out of 23,000, against a national NAS share of 21%.

Cancellations run at 3.49%, against 1.81% nationally. That is about one flight in 30 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.

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. 9.0% 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 5am–8am window matters as much as it does.

The return leg runs 79.3% on time across 1,368 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.

The sample behind these figures is 1,346 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this

Booking Republic on CVG to ORD

Put together: the delay figures matter less here than the 3.49% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 1,298 completed flights over 12 months sit behind that.
