Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| YX4765 | 72.8% | 2.33% | -2 min | 7.5% | 900 |
| Republic Airways on RDU → JFK | 80.1% | 3.48% | -8 min | 7.3% | 4,336 |
| All RDU → JFK flights | 77.6% | 3.66% | -8 min | 9.2% | 9,864 |
YX4765 has cancelled 2.33% of its scheduled departures (21 of 900), against 3.66% for all RDU → JFK flights — this specific departure cancels 1.3 percentage points less often than the route as a whole. Different flight numbers on the same route can carry different aircraft, crews and schedules, so this is a fact about YX4765 specifically, not about the route it flies.

Why YX4765 runs late
Where US DOT attributed the delay minutes on this flight.
airspace and airport capacity, including weather-driven flow control
the inbound aircraft was late, so this flight started late
weather severe enough to stop this flight specifically
crew, maintenance, boarding and fueling, all within the carrier’s control
Share of the delay minutes US DOT attributed to each cause for YX4765 on RDU → JFK. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies YX4765 comes in late, and what that does to the departure.
The aircraft flying YX4765 came in 15 or more minutes late on 11% of the departures where its previous flight is known. There are not enough departures in both groups to say how the flight left after a late one and after an on-time one.
Each departure is matched to the flight the same aircraft flew into RDU just before it, using the tail number in the DOT file, 850 of 880 departures in all. A departure is left out when that flight is unknown, was cancelled or diverted, or the aircraft had sat for more than 12 hours. A flight the airline cancelled never left and is not in the count, and one flown by a substitute aircraft is matched to the aircraft that flew it, not to the one first planned.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late |
|---|---|
| YX4765 | 11% |
| Network, same turn | 18% |
The schedule leaves little slack between the inbound landing and this departure, so a late arrival has almost nowhere to go but into the departure.
The network row is every flight with a scheduled turn of 30 to 44 minutes. How often YX4765’s aircraft landed 15 or more minutes late is lower than the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves RDU late, does that still matter by the time it reaches JFK?
On arrival at JFK, YX4765 spends 12.2 min taxiing from touchdown to the gate — ground time a connecting passenger sits through before they can even leave the aircraft, on top of however late the flight itself ran. That is about what any arrival at JFK spends on the ground before reaching the gate.
Departure delay is averaged over every pushback and arrival delay over every completed arrival, so the two counts differ by the flights that never reached JFK. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 11,497 departures from RDU scheduled in the clock hour YX4765 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at JFK (351,546 flights), not just YX4765’s own. More on taxi time.

The hour it leaves RDU
Part of any flight’s record belongs to the clock rather than to the flight. YX4765 has one departure time, so this is what that time is worth.
On-time arrival rate. 11,497 departures from RDU are scheduled in the 12 PM–1 PM hour over the period, against 179,935 across the whole day.
YX4765 is scheduled out of RDU at 12:07 PM, in the 12 PM–1 PM bank. Departures from RDU in that hour arrive on time 79.5% of the time against 79.4% across the airport’s whole day, so the hour YX4765 leaves in is an ordinary one for RDU and explains nothing about its record either way.
The two airport figures cover every departure from RDU to every destination, so they describe the slot rather than this journey — the like-for-like comparison against the route is above. Hours are scheduled local, and a number whose schedule moved between banks inside the period has no single hour and is not described here at all. Why the hour matters.

By day of week
Does YX4765 run worse on particular days?
Wednesday is historically the most reliable day and Saturday the least, a gap of 15.5 percentage points.

Other routes YX4765 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.

| DCA→TPA Washington to Tampa | April 7, 2026 – May 6, 2026 | 26 | — |
| TPA→DCA Tampa to Washington | April 7, 2026 – May 6, 2026 | 26 | — |

Because the same number has served different journeys, the statistics above describe only the route YX4765 currently operates. Blending them would produce an average of two different flights.

Same airports, same journey, different odds of arriving on time.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. YX4765 is placed in the same ordering rather than left out of it; the rows around it are the most punctual departures on the route, not all of them, so this is a comparison and not a rank. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 900 records of YX4765 operating RDU → JFK, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
