Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Republic Airways.
Republic on JFK to RDU carries a cancellation problem, not just a delay problem: 6.3% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, close to three flights in four arrive on time, worth a B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 1,376 flights, with a median arrival 5 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Republic on JFK to RDU from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

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 22 points, against half a point between the best and worst carrier.

Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 62.6% on time, against 84.3% for the 8am–11am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 8am–11am window is the busiest, with 351 flights scheduled in it.
Across the year
Republic on JFK to RDU through the year
July is the worst month at 52.1% on time, 36 points below May, the best at 88.2%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. November was the busiest month here, with 147 flights.

Share of 1,286 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 228 departures that left 15 minutes late or more, only 22 made it up before arrival. In the other direction, 115 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 RDU.
The worst days
Worst days for Republic on JFK to RDU
The latest arrival of the period was on 20 August 2026, 15 hours 53 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 20 August 2026 | 15 hours 53 minutes | Late-arriving aircraft |
| 6 May 2026 | 7 hours 46 minutes | Carrier |
| 8 March 2026 | 5 hours 44 minutes | Late-arriving aircraft |
| 14 December 2025 | 4 hours 28 minutes | Late-arriving aircraft |

Delay causes
Why Republic runs late on this route
Late-arriving aircraft accounts for 53% of the 21,000 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Late-arriving aircraft
- 31%National Airspace System
- 15%Carrier
- 1%Extreme weather
- 0%Security
53% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 21,000 reported delay minutes here, that single category outweighs weather by 40 to one. The split is drawn from 21,165 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 84.3% on time here.
Cancellations run at 6.32%, 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
9.6% 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 427 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 runs 77.2% on time across 1,375 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
The sample behind these figures is 1,376 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
What to do with this
Booking Republic on JFK to RDU
Put together: the delay figures matter less here than the 6.32% cancellation rate. A late arrival costs you about an hour; 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. 1,286 completed flights over 12 months sit behind that.
