The aircraft flying YX3437 came in 15 or more minutes late on 15% 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 EWR just before it, using the tail number in the DOT file, 555 of 608 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.

YX3437 pushes back an average of 5.9 minutes late and reaches the gate at DTW an average of 1.5 minutes early. The 7.5 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 22.5 minutes on the taxiways at EWR, 2.4 minutes shorter than a typical EWR departure in the same hour.

On arrival at DTW, YX3437 spends 10.7 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 1.3 minutes longer than a typical DTW arrival (9.3 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 DTW. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 25,934 departures from EWR scheduled in the clock hour YX3437 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at DTW (388,616 flights), not just YX3437’s own. More on taxi time.

YX3437 is scheduled out of EWR at 4:00 PM, in the 4 PM–5 PM bank. Departures from EWR in that hour arrive on time 73.7% of the time against 77.7% across the airport’s whole day — the slot alone is worth 4.0 points worse before anything about this particular flight is considered.

The two airport figures cover every departure from EWR 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 YX3437 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. YX3437 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.
