Historical statistics for July 2025 to June 2026, not live status. For today’s YX 4765, 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 4765 sits in the middle of the pack with a C−. About seven flights in ten arrive on time by the DOT's definition, 6 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 290 flights, with a median arrival 4 minutes early.

These figures cover 290 flights between July 2025 and June 2026. Beyond the headline rate, 10.0% 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.

Schedule

When YX 4765 flies

YX 4765 flies RDU to JFK without a single fixed slot. Its most common scheduled departure was 10:40, used on 33 of 290 flights. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 10:40 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and YX 4765 runs 12 points worse at 71.9%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

YX 4765 quarter by quarter

Quarter by quarter YX 4765 held fairly steady: 72.2% in Jul–Sep 2025, 67.8% in Oct–Dec 2025, 76.7% in Jan–Mar 2026 and 73.2% in Apr–Jun 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights72.2%

Scale runs 60% to 80%. Rows with fewer than 30 flights show a dash.

By weekday, YX 4765 did best on Friday at 81.0% on time and worst on Sunday at 64.9%. Each day rests on about 41 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 4765 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 43% of the 5,333 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%
National Airspace System
36%
Extreme weather
12%
Carrier
9%

Extreme weather accounts for 12% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 1.9 times the usual weather exposure. The split is drawn from 5,333 delay minutes reported on YX 4765.

Cancellations run at 3.10%, 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.0% 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 same number turns up on four other city pairs in the data, including DCA to TPA (26), TPA to DCA (26) and ORD to SDF (4), but none flew often enough under YX 4765 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RDU to JFK only.

One caution: this is a thin sample. 290 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 4765

For a booking, the cancellation rate is the figure to plan around on YX 4765: 3.10% of its 290 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
