Historical statistics for July 2025 to June 2026, not live status. For today’s YX 4658, check with Republic Airways. Republic Airways flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.
YX 4658 sits in the middle of the pack with a C−. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.6%. The late ones land about 55 minutes behind schedule. That rests on 280 flights, with a median arrival 2 minutes early.

These figures cover 280 flights between July 2025 and June 2026. The median arrival is 2 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.
Schedule
When YX 4658 flies
YX 4658 flies JFK to RDU without a single fixed slot. Its most common scheduled departure was 15:59, used on 50 of 280 flights, with 12:59 (39 flights) and 15:26 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 15:59 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and YX 4658 runs 2 points better at 74.6%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
YX 4658 quarter by quarter
YX 4658 did not run the same all year. Its best quarter was Apr–Jun 2026 at 91.5% on time and its weakest Oct–Dec 2025 at 57.4%, a swing of 34 points on roughly 70 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

- Oct–Dec 202556 flights57.4%
- Jan–Mar 202685 flights62.8%
- Apr–Jun 202647 flights91.5%
Scale runs 50% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, YX 4658 did best on Sunday at 78.9% on time and worst on Thursday at 64.1%. Each day rests on about 40 flights, so a gap of 15 points is worth noticing but could still narrow in another year.
Delay causes
Why YX 4658 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 47% of the 3,674 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.
- 47%Late-arriving aircraft
- 39%National Airspace System
- 14%Carrier
- 0%Extreme weather
47% 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 3,674 reported delay minutes here, that single category outweighs weather by 47 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 3,674 delay minutes reported on YX 4658.
Cancellations run at 3.57%, 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 routes
What a delay on this flight costs
7.1% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 55 minutes, which a normal layover absorbs.
The same number turns up on one other city pair in the data, including LGA to STL (38), but none flew often enough under YX 4658 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to JFK to RDU only.
One caution: this is a thin sample. 280 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 YX 4658
For a booking, the cancellation rate is the figure to plan around on YX 4658: 3.57% of its 280 scheduled flights did not operate. A late arrival costs about 55 minutes, but a cancellation costs the day, so leave a later option open.
