Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Republic Airways.
Republic on EWR to ORD earns an F−, which is as low as this site's scale goes for a reason. Only 52.8% of flights arrive inside the 15-minute window, 25 points worse than the national rate of 77.6%. Late arrivals average an hour and a half. Treat any tight connection here as a coin flip. That rests on 102 flights. The strongest carrier on the route with a full sample, American Airlines, flew 735 at 77.8% on time.
American Airlines is the most reliable of the three carriers covered here at 77.8% on time across 735 flights.

These figures cover 102 flights between July 2025 and June 2026. Beyond the headline rate, 23.6% 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 EWR to ORD
Republic flew 102 of the 6,039 flights on EWR to ORD, about 2% of it. Its 52.8% on time is 19 points worse than the route as a whole, which runs 71.5%. Ranked by on-time rate it is last of five carriers on the route, where the range runs from American at 77.8% to Republic at 52.8%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. American Airlines arrives on time 77.8% of the time; United Airlines manages 71.1%. Sample sizes sit next to every figure, because a two-point gap across 4,389 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| American Airlines | 735 | 77.8% | 108 min | 3.81% | B− |
| Envoy Air | 657 | 73.2% | 89 min | 5.48% | C− |
| United Airlines | 4,389 | 71.1% | 76 min | 2.26% | C |

| Republic Airways (this page)thin sample | 102 | 52.8% | 82 min | 11.76% | F− |
Envoy Air cancels 5.5% 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 is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 102 flights.
There are not enough flights in each departure window to split Republic's EWR to ORD record by time of day without the percentages moving on noise. The headline rate of 52.8% is the reliable figure here.
Across the year
Republic on EWR to ORD through the year
- Oct–Dec 202547 flights40.5%
- Jan–Mar 202650 flights63.6%
- Apr–Jun 20265 flights—
Scale runs 30% to 70%. Rows with fewer than 30 flights show a dash.
Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 52.8% on time across 102 flights.
Split by quarter, Republic on EWR to ORD logged 47 flights in Oct–Dec 2025, 50 flights in Jan–Mar 2026 and 5 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 52.8% annual figure is the one to use.
Delay causes
Why Republic runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 65% of the 3,459 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.
- 65%Late-arriving aircraft
- 30%National Airspace System
- 4%Carrier
- 1%Extreme weather
65% 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 3,459 reported delay minutes here, that single category outweighs weather by 65 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 3,459 reported delay minutes.
Cancellations run at 11.76%, against 1.81% nationally. That is about one flight in nine 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. 23.6% 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.
The 719 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The return leg is a different operation and performs like one: it runs 60.2% on time across 102 flights, 7 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 7 points of difference.
One caution: this is a thin sample. 102 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 EWR to ORD
Put together: the delay figures matter less here than the 11.76% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 5pm–8pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 89 completed flights over 12 months sit behind that.
