YX5749 has cancelled 1.87% of its scheduled departures (14 of 750), against 4.07% for all LGA → DCA flights — this specific departure cancels 2.2 percentage points less 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 YX5749 specifically, not about the route it flies.

Does a late aircraft delay this flight?

How often the plane that flies YX5749 comes in late, and what that does to the departure.

Inbound aircraft late
12%
87 of 711 departures came in 15+ minutes late
Scheduled time on the ground
58 minutes
Median at LGA between the inbound and this departure

The aircraft flying YX5749 came in 15 or more minutes late on 12% 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, 711 of 737 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.

YX574912%
Network, same turn18%

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 45 to 59 minutes. How often YX5749’s aircraft landed 15 or more minutes late is lower than 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 DCA?

Leaves the gate
4.8 minutes late
Average over 737 pushbacks
Taxi out at LGA
27.1 min
23.6 min for the airport in this hour
Taxi in at DCA
6.2 min
7.6 min for a typical DCA arrival
Reaches the gate at DCA
1.7 minutes early
Average over 734 arrivals

YX5749 pushes back an average of 4.8 minutes late and reaches the gate at DCA an average of 1.7 minutes early. The 6.5 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 27.1 minutes on the taxiways at LGA, 3.5 minutes longer than a typical LGA departure in the same hour.

On arrival at DCA, YX5749 spends 6.2 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 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 29,166 departures from LGA scheduled in the clock hour YX5749 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 YX5749’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. YX5749 has one departure time, so this is what that time is worth.

YX574983.1%
All LGA departures, 11 AM–12 PM82.0%
All LGA departures, whole day78.3%

On-time arrival rate. 29,166 departures from LGA are scheduled in the 11 AM–12 PM hour over the period, against 456,467 across the whole day.

YX5749 is scheduled out of LGA at 11:30 AM, in the 11 AM–12 PM bank. Departures from LGA in that hour arrive on time 82.0% of the time against 78.3% across the airport’s whole day — the slot alone is worth 3.7 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 YX5749 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. YX5749 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 750 records of YX5749 operating LGA → DCA, 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.
