YX4805 has cancelled 2.17% of its scheduled departures (16 of 739), against 3.66% for all RDU → JFK flights — this specific departure cancels 1.5 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 YX4805 specifically, not about the route it flies.

YX4805 is usually the aircraft’s first flight of the day: the schedule gives it a median of 7.1 hours on the ground at RDU, so its “inbound” is mostly the aircraft’s arrival the evening before.

When the aircraft came in 15 or more minutes late, YX4805 pushed back an average of 5 minutes late; when it came in on time or early, an average of 2 minutes early.

Each departure is matched to the flight the same aircraft flew into RDU just before it, using the tail number in the DOT file, 659 of 723 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.

YX4805 pushes back an average of 1.9 minutes late and reaches the gate at JFK an average of 5.3 minutes early. The 7.1 minutes between those two figures are slack the published schedule already carries, which is why a late pushback on this flight does not reliably become a late arrival. It spends 19.0 minutes on the taxiways at RDU, 1.1 minutes longer than a typical RDU departure in the same hour.

On arrival at JFK, YX4805 spends 11.6 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 22,803 departures from RDU scheduled in the clock hour YX4805 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 YX4805’s own. More on taxi time.

YX4805 is scheduled out of RDU at 6:00 AM, in the 6 AM–7 AM bank. Departures from RDU in that hour arrive on time 90.2% of the time against 79.4% across the airport’s whole day — the slot alone is worth 10.9 points better before anything about this particular flight is considered.

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.

Because the same number has served different journeys, the statistics above describe only the route YX4805 currently operates. Blending them would produce an average of two different flights.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. YX4805 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.
