Republic on RDU to EWR earns an A−. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 50 minutes. That rests on 239 flights, with a median arrival 21 minutes early.

Set against the rest of the country, Republic's RDU to EWR record is 9 points better than the US average of 77.6%. That gap is worth roughly 85 fewer late arrivals for every thousand flights.

These figures cover 239 flights between July 2025 and June 2026. The median arrival is 21 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 RDU to EWR

Republic flew 239 of the 1,975 flights on RDU to EWR, about 12% of it. Its 86.1% on time is 11 points better than the route as a whole, which runs 74.9%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Republic at 86.1% to Spirit at 54.1%. 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 239 flights.

  • 5am–8am5 flights
  • 8am–11am9 flights
  • 11am–2pm108 flights88.7%
  • 2pm–5pm4 flights
  • 5pm–8pm113 flights82.2%
  • 8pm–5am

Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.

The best window here is not the first bank but the 11am–2pm slot at 88.7% on time, ahead of 5pm–8pm at 82.2%. 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.

Across the year

Republic on RDU to EWR through the year

  • Jul–Sep 202514 flights
  • Oct–Dec 202515 flights
  • Jan–Mar 202666 flights80.6%
  • Apr–Jun 2026144 flights90.8%

Scale runs 70% to 95%. 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 86.1% on time across 239 flights.

Split by quarter, Republic on RDU to EWR logged 14 flights in Jul–Sep 2025, 15 flights in Oct–Dec 2025, 66 flights in Jan–Mar 2026 and 144 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 86.1% annual figure is the one to use.

Across the week, Sunday is the strongest day at 97.1% on time and Saturday the weakest at 85.5%. 12 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. National Airspace System accounts for 56% of the 1,587 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.

  • National Airspace System
    56%
  • Late-arriving aircraft
    34%
  • Carrier
    11%

56% 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 883 minutes out of 1,587, against a national NAS share of 21%. The split is drawn from 1,587 reported delay minutes.

Cancellations run at 3.35%, 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 3.5% 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 11am–2pm window matters as much as it does.

The return leg is a different operation and performs like one: it runs 93.6% on time across 241 flights, 8 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 8 points of difference.

One caution: this is a thin sample. 239 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 RDU to EWR

Put together: the delay figures matter less here than the 3.35% cancellation rate. A late arrival costs you about 50 minutes; 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. 231 completed flights over 12 months sit behind that.
