Why YX4682 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
weather severe enough to stop this flight specifically
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control

Does a late aircraft delay this flight?
How often the plane that flies YX4682 comes in late, and what that does to the departure.
YX4682 is usually the aircraft’s first flight of the day: the schedule gives it a median of 8.4 hours on the ground at ILM, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, YX4682 pushed back an average of 11 minutes late; when it came in on time or early, an average of 1 minute early.
Each departure is matched to the flight the same aircraft flew into ILM just before it, using the tail number in the DOT file, 703 of 807 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.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| YX4682 | 26% | 10% | 5% |
| Network, same turn | 29% | 12% | 9% |
A night on the ground absorbs most of a late arrival, so a late inbound matters far less on a turn this long than on a same-day one.
The network row is every flight with a scheduled turn of 6 hours or more, usually overnight. How often YX4682’s aircraft landed 15 or more minutes late is lower than the network’s and, once the aircraft was late, how often YX4682 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves ILM late, does that still matter by the time it reaches LGA?
YX4682 pushes back an average of 4.3 minutes late and reaches the gate at LGA an average of 2.0 minutes late. The 2.2 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. Its 16.0 minutes on the taxiways at ILM is about what any departure from the airport in that hour spends.
On arrival at LGA, YX4682 spends 10.0 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 1.8 minutes longer than a typical LGA arrival (8.2 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 LGA. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 3,869 departures from ILM scheduled in the clock hour YX4682 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at LGA (456,481 flights), not just YX4682’s own. More on taxi time.

The hour it leaves ILM
Part of any flight’s record belongs to the clock rather than to the flight. YX4682 has one departure time, so this is what that time is worth.
On-time arrival rate. 3,869 departures from ILM are scheduled in the 6 AM–7 AM hour over the period, against 23,754 across the whole day.
YX4682 is scheduled out of ILM at 6:00 AM, in the 6 AM–7 AM bank. Departures from ILM in that hour arrive on time 91.5% of the time against 81.7% across the airport’s whole day — the slot alone is worth 9.8 points better before anything about this particular flight is considered.
The two airport figures cover every departure from ILM 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.

By day of week
Does YX4682 run worse on particular days?
Tuesday is historically the most reliable day and Monday the least, a gap of 3.3 percentage points.

Other routes YX4682 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.

Because the same number has served different journeys, the statistics above describe only the route YX4682 currently operates. Blending them would produce an average of two different flights.

Data and methodology
Calculated by FlyerIntel from 840 records of YX4682 operating ILM → LGA, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
