The aircraft flying YX5672 came in 15 or more minutes late on 10% 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 BOS just before it, using the tail number in the DOT file, 643 of 666 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.

YX5672 pushes back an average of 2.7 minutes late and reaches the gate at DCA an average of 3.6 minutes early. The 6.2 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 21.2 minutes on the taxiways at BOS, 2.3 minutes longer than a typical BOS departure in the same hour.

On arrival at DCA, YX5672 spends 5.7 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 1.9 minutes shorter than a typical DCA arrival (7.6 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 DCA. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 24,250 departures from BOS scheduled in the clock hour YX5672 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at DCA (435,126 flights), not just YX5672’s own. More on taxi time.

YX5672 is scheduled out of BOS at 11:05 AM, in the 11 AM–12 PM bank. Departures from BOS in that hour arrive on time 81.9% of the time against 77.2% across the airport’s whole day — the slot alone is worth 4.7 points better before anything about this particular flight is considered.

The two airport figures cover every departure from BOS 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 YX5672 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. YX5672 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.
