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

Republic on ORD to CID sits in the middle of the pack with a C−. About seven flights in ten arrive on time by the DOT's definition, 5 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 354 flights. The strongest carrier on the route with a full sample, Envoy Air, flew 964 at 72.2% on time.

The national on-time rate over the same period is 77.6%, so Republic on ORD to CID runs 5 points behind the country as a whole. Across a thousand flights that is about 52 extra late arrivals.

These figures cover 354 flights between July 2025 and June 2026. Beyond the headline rate, 12.2% 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

Republic against every carrier on ORD to CID

Republic flew 354 of the 2,715 flights on ORD to CID, about 13% of it. Its 72.4% on time is 5 points better than the route as a whole, which runs 67.8%. Ranked by on-time rate it is first of five carriers on the route, where the range runs from Republic at 72.4% to American at 60.3%. One 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 72.2% of the time; United Airlines manages 63.4%. Sample sizes sit next to every figure, because a two-point gap across 456 flights means less than a ten-point one.

SkyWest Airlines cancels 5.2% 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 15 points, against 9 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am
  • 8am–11am65 flights70.0%
  • 11am–2pm97 flights82.3%
  • 2pm–5pm59 flights67.3%
  • 5pm–8pm113 flights67.9%
  • 8pm–5am20 flights

Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.

The best window here is not the first bank but the 11am–2pm slot at 82.3% on time, ahead of 2pm–5pm at 67.3%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 5pm–8pm window is the busiest, with 113 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 72.4% on time across 354 flights.

Quarter by quarter Republic on ORD to CID held fairly steady: 69.5% in Oct–Dec 2025, 71.0% in Jan–Mar 2026 and 76.9% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Across the week, Saturday is the strongest day at 82.1% on time and Thursday the weakest at 66.7%. 15 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Republic runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 45% of the 6,365 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.

  • Late-arriving aircraft
    45%
  • National Airspace System
    31%
  • Carrier
    17%
  • Extreme weather
    7%

45% 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 6,365 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 6,365 reported delay minutes.

Cancellations run at 4.80%, against 1.81% nationally. That is about one flight in twenty 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. 12.2% 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 196 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 11am–2pm window matters as much as it does.

The return leg is a different operation and performs like one: it runs 66.9% on time across 354 flights, 6 points below 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 6 points of difference.

One caution: this is a thin sample. 354 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 Republic on ORD to CID

Put together: the delay figures matter less here than the 4.80% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 337 completed flights over 12 months sit behind that.
