Why YX5761 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
the inbound aircraft was late, so this flight started late
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for YX5761 on LGA → BOS. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies YX5761 comes in late, and what that does to the departure.
The aircraft flying YX5761 came in 15 or more minutes late on 17% 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 LGA just before it, using the tail number in the DOT file, 701 of 738 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 |
|---|---|
| YX5761 | 17% |
| Network, same turn | 17% |
The schedule leaves a normal turn: enough time to clean and board if the aircraft is on time, little to spare if it is not.
The network row is every flight with a scheduled turn of 60 to 89 minutes. How often YX5761’s aircraft landed 15 or more minutes late is about the same as the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves LGA late, does that still matter by the time it reaches BOS?
YX5761 pushes back an average of 6.7 minutes late and reaches the gate at BOS an average of 0.7 minutes early. The 7.4 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 24.2 minutes on the taxiways at LGA, 2.3 minutes longer than a typical LGA departure in the same hour.
On arrival at BOS, YX5761 spends 10.4 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 27,622 departures from LGA scheduled in the clock hour YX5761 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 YX5761’s own. More on taxi time.

The hour it leaves LGA
Part of any flight’s record belongs to the clock rather than to the flight. YX5761 has one departure time, so this is what that time is worth.
On-time arrival rate. 27,622 departures from LGA are scheduled in the 12 PM–1 PM hour over the period, against 456,467 across the whole day.
YX5761 is scheduled out of LGA at 12:00 PM, in the 12 PM–1 PM bank. Departures from LGA in that hour arrive on time 81.9% of the time against 78.3% across the airport’s whole day — the slot alone is worth 3.6 points better 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 YX5761 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. YX5761 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.
Data and methodology
Calculated by FlyerIntel from 759 records of YX5761 operating LGA → BOS, 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.
