DL1054 has cancelled 2.94% of its scheduled departures (22 of 748), against 1.85% for all RDU → BOS flights — this specific departure cancels 1.1 percentage points more 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 DL1054 specifically, not about the route it flies.

DL1054 is usually the aircraft’s first flight of the day: the schedule gives it a median of 9 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, DL1054 pushed back an average of 1 minute 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, 698 of 726 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.

DL1054 pushes back an average of 1.9 minutes late and reaches the gate at BOS an average of 10.6 minutes early. The 12.4 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 17.0 minutes on the taxiways at RDU, 1.3 minutes shorter than a typical RDU departure in the same hour.

On arrival at BOS, DL1054 spends 10.5 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 1.5 minutes longer than a typical BOS arrival (9.0 min).

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 BOS. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 16,752 departures from RDU scheduled in the clock hour DL1054 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at BOS (440,886 flights), not just DL1054’s own. More on taxi time.

DL1054 is scheduled out of RDU at 7:00 AM, in the 7 AM–8 AM bank. Departures from RDU in that hour arrive on time 87.0% of the time against 79.4% across the airport’s whole day — the slot alone is worth 7.6 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 DL1054 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. DL1054 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.
