YX5747
Washington (DCA) to New York (LGA) · scheduled 1:40 PM – 4:00 PM
How YX5747 performs
644 operations, June 2024 – July 2026.
YX5747 arrived on time 72.8% of the time, against 74.0% for all DCA → LGA flights, so this departure is 1.2 percentage points worse than the route as a whole. Against Republic Airways’ own flights on this route it is 1.7 points worse.
YX5747’s scheduled departure has moved during the period FlyerIntel has on file: it typically left around 2:45 PM earlier on, and around 1:45 PM more recently — a 60-minute shift, not the few minutes of day-to-day rounding every published schedule carries. Confirm the current departure time before booking around an older listing.

Why YX5747 runs late
Where US DOT attributed the delay minutes on this flight.
airspace and airport capacity, including weather-driven flow control
crew, maintenance, boarding and fueling, all within the carrier’s 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 YX5747 on DCA → LGA. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies YX5747 comes in late, and what that does to the departure.
The aircraft flying YX5747 came in 15 or more minutes late on 16% 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 DCA just before it, using the tail number in the DOT file, 598 of 621 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 |
|---|---|
| YX5747 | 16% |
| 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 YX5747’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 DCA late, does that still matter by the time it reaches LGA?
On arrival at LGA, YX5747 spends 9.5 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 1.4 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 27,647 departures from DCA scheduled in the clock hour YX5747 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 YX5747’s own. More on taxi time.

The hour it leaves DCA
Part of any flight’s record belongs to the clock rather than to the flight. YX5747 has one departure time, so this is what that time is worth.
On-time arrival rate. 27,647 departures from DCA are scheduled in the 1 PM–2 PM hour over the period, against 435,076 across the whole day.
YX5747 is scheduled out of DCA at 1:40 PM, in the 1 PM–2 PM bank. Departures from DCA in that hour arrive on time 74.9% of the time against 76.5% across the airport’s whole day, so the hour YX5747 leaves in is an ordinary one for DCA and explains nothing about its record either way.
The two airport figures cover every departure from DCA 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 YX5747 currently operates. Blending them would produce an average of two different flights.
When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
56 min late
against a median of 5 min early
YX5747 has an average that understates its risk: a typical arrival is 5 min early, but the worst tenth are 61 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Other flights on this route
Same airports, same journey, different odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|
| YX5747 this flight | Republic Airways | 72.8% | 5 min early | 644 |

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. YX5747 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 644 records of YX5747 operating DCA → 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.
