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

Republic on EWR to RDU earns an A−. Nearly every flight arrives inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 16 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 50 minutes. That rests on 241 flights, with a median arrival 17 minutes early.

Set against the rest of the country, Republic's EWR to RDU record is 16 points better than the US average of 77.6%. That gap is worth roughly 160 fewer late arrivals for every thousand flights.

These figures cover 241 flights between July 2025 and June 2026. The median arrival is 17 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier

Republic against every carrier on EWR to RDU

Republic flew 241 of the 1,976 flights on EWR to RDU, about 12% of it. Its 93.6% on time is 17 points better than the route as a whole, which runs 76.8%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Republic at 93.6% to Spirit at 60.8%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

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 241 flights.

5am–8am14 flights—
8am–11am61 flights98.3%
11am–2pm52 flights96.2%
2pm–5pm113 flights90.7%
5pm–8pm1 flights—
8pm–5am—

Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.

The early departures do better, though not dramatically: 98.3% on time for the 8am–11am window against 90.7% for 2pm–5pm. Worth taking if the schedule allows, not worth an extra connection. The 2pm–5pm 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 93.6% on time across 241 flights.

Split by quarter, Republic on EWR to RDU logged 14 flights in Jul–Sep 2025, 15 flights in Oct–Dec 2025, 66 flights in Jan–Mar 2026 and 146 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 93.6% annual figure is the one to use.

Across the week, Friday is the strongest day at 100.0% on time and Saturday the weakest at 93.5%. 7 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 43% of the 727 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.

43% 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 727 reported delay minutes here, that single category outweighs weather by 43 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 727 reported delay minutes.

The largest share of delay minutes, 35%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 255 of the 727 delay minutes reported here.

Cancellations run at 3.32%, 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

Badly late arrivals are rare here: only 1.7% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

At 416 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 86.1% on time across 239 flights, 8 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 8 points of difference.

One caution: this is a thin sample. 241 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 RDU

Put together: the delay figures matter less here than the 3.32% cancellation rate. A late arrival costs you roughly 50 minutes; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 233 completed flights over 12 months sit behind that.
