Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| YX5742 | 84.7% | 2.59% | -10 min | 2.8% | 618 |
| Republic Airways on LGA → DCA | 75.9% | 4.46% | -8 min | 8.3% | 12,083 |

YX5742 has cancelled 2.59% of its scheduled departures (16 of 618), against 4.18% for all LGA → DCA flights — this specific departure cancels 1.6 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 YX5742 specifically, not about the route it flies.
2.8% of YX5742’s arrivals were an hour or more late, against 8.5% across LGA → DCA, so the long delays are less common on this number than on the route.

Why YX5742 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
screening or terminal security incidents

Does a late aircraft delay this flight?
How often the plane that flies YX5742 comes in late, and what that does to the departure.
The aircraft flying YX5742 came in 15 or more minutes late on 10% 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.
Matched by tail number to the aircraft’s previous flight into LGA: 519 of 602 departures. Unknown, cancelled or diverted inbounds and gaps over 12 hours are left out.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late |
|---|---|
| YX5742 | 10% |
| Network, same turn | 18% |
52 scheduled minutes is enough to clean and board when the aircraft is on time, with little to spare when it is not.
The network row is every flight with a scheduled turn of 45 to 59 minutes. How often YX5742’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?
YX5742 pushes back an average of 1.0 minutes late and reaches the gate at DCA an average of 2.4 minutes early. The 3.4 minutes between those two figures are slack the published schedule already carries, so on average a late pushback on this flight is made up before the gate. It spends 26.8 minutes on the taxiways at LGA, 3.5 minutes longer than a typical LGA departure in the same hour.
On arrival at DCA, YX5742 spends 7.7 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 about what any arrival at DCA spends on the ground before reaching the gate.
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 29,750 LGA departures. Taxi-in is landing to gate, set against 447,280 arrivals at DCA. More on taxi time.

Data and methodology
Calculated by FlyerIntel from 618 records of YX5742 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 reported separately, not in the on-time rate.
