Why YX4710 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically
crew, maintenance, boarding and fueling, all within the carrier’s control
screening or terminal security incidents
Share of the delay minutes US DOT attributed to each cause for YX4710 on JFK → BNA. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies YX4710 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, YX4710 pushed back an average of 51 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 JFK just before it, using the tail number in the DOT file, 912 of 936 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 |
|---|---|---|---|
| YX4710 | 19% | 65% | 6% |
| Network, same turn | 18% | 85% | 10% |
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 YX4710’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often YX4710 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves JFK late, does that still matter by the time it reaches BNA?
On arrival at BNA, YX4710 spends 13.3 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 5.5 minutes longer than a typical BNA arrival (7.8 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 BNA. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 25,963 departures from JFK scheduled in the clock hour YX4710 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at BNA (319,633 flights), not just YX4710’s own. More on taxi time.

The hour it leaves JFK
Part of any flight’s record belongs to the clock rather than to the flight. YX4710 has one departure time, so this is what that time is worth.
On-time arrival rate. 25,963 departures from JFK are scheduled in the 3 PM–4 PM hour over the period, against 351,635 across the whole day.
YX4710 is scheduled out of JFK at 3:59 PM, in the 3 PM–4 PM bank. Departures from JFK in that hour arrive on time 73.8% of the time against 77.0% across the airport’s whole day — the slot alone is worth 3.2 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from JFK 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 YX4710 run worse on particular days?
Tuesday is historically the most reliable day and Thursday the least, a gap of 13.8 percentage points.

Other routes YX4710 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.
| Route | Operated | Flights | On time |
|---|---|---|---|
| PHL→SDF Philadelphia to Louisville | December 25, 2023 | 1 | — |
| SDF→PHL Louisville to Philadelphia | December 25, 2023 | 1 | — |
| ORD→IND Chicago to Indianapolis | November 26, 2023 | 1 | — |
Because the same number has served different journeys, the statistics above describe only the route YX4710 currently operates. Blending them would produce an average of two different flights.

Data and methodology
Calculated by FlyerIntel from 972 records of YX4710 operating JFK → BNA, 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.
