YX4598 has cancelled 8.40% of its scheduled departures (70 of 833), against 3.07% for all LGA → DTW flights — this specific departure cancels 5.3 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 YX4598 specifically, not about the route it flies.

Share of the delay minutes US DOT attributed to each cause for YX4598 on LGA → DTW. Only delays of 15 minutes or more are attributed.

When the aircraft came in 15 or more minutes late, YX4598 pushed back an average of 50 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 LGA just before it, using the tail number in the DOT file, 751 of 765 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.

YX4598 pushes back an average of 16.1 minutes late and reaches the gate at DTW an average of 13.7 minutes late. The 2.4 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. Its 26.5 minutes on the taxiways at LGA is about what any departure from the airport in that hour spends.

On arrival at DTW, YX4598 spends 12.5 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 3.2 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 24,627 departures from LGA scheduled in the clock hour YX4598 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 YX4598’s own. More on taxi time.

YX4598 is scheduled out of LGA at 8:29 PM, in the 8 PM–9 PM bank. Departures from LGA in that hour arrive on time 69.4% of the time against 78.3% across the airport’s whole day — the slot alone is worth 8.9 points worse before anything about this particular flight is considered.

The two airport figures cover every departure from LGA 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 YX4598 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. YX4598 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.
