Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Republic Airways.
Republic on CLE to ORD lands a B−, level with the national rate of 77.3%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 587 flights. The strongest carrier on the route with a full sample, United Airlines, flew 2,181 at 75.6% on time.
The US average over the same twelve months is 77.3%, so there is little to separate Republic on CLE to ORD from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
Republic against every carrier on CLE to ORD
Republic flew 587 of the 4,895 flights on CLE to ORD, about 12% of it. Its 76.9% on time is 2 points better than the route as a whole, which runs 74.5%. Ranked by on-time rate it is first of five carriers on the route, where the range runs from Republic at 76.9% to SkyWest at 69.2%.
The choice of carrier is not cosmetic here. United Airlines arrives on time 75.6% of the time; SkyWest Airlines manages 69.2%. Sample sizes sit next to every figure, because a two-point gap across 854 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Republic Airways (this page) | 587 | 76.9% | 75 min | 6.64% | B− |
| United Airlines | 2,181 | 75.6% | 79 min | 1.47% | B |

| SkyWest Airlines | 854 | 69.2% | 97 min | 4.22% | C− |
Envoy Air cancels 4.3% 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.

Book the early departure. Flights leaving between 5am–8am arrive on time 82.8% of the time, against 68.1% for the overnight window. That is 15 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 2pm–5pm window is the busiest, with 199 flights scheduled in it.

Share of 546 completed flights by arrival against schedule.
18 of 114 late departures made up the time and arrived on time, 16% of them. In the other direction, 30 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at ORD.

The latest arrival of the period was on 27 April 2026, 12 hours 43 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The same cause led on three of the five worst days.

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 9,449 reported delay minutes.
- 41%Late-arriving aircraft
- 37%National Airspace System
- 20%Carrier
- 2%Extreme weather
41% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 9,449 reported delay minutes here, that single category outweighs weather by 21 to one. The split is drawn from 9,449 reported delay minutes.
37% 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 3,506 minutes out of 9,449, against a national NAS share of 21%.
Cancellations run at 6.64%, against 1.89% nationally. That is about one flight in fifteen 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
9.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
At 316 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 76.2% on time across 583 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 587 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 CLE to ORD
Put together: the delay figures matter less here than the 6.64% 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. 546 completed flights over 12 months sit behind that.
