Why B61601 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 B61601 comes in late, and what that does to the departure.
The aircraft flying B61601 came in 15 or more minutes late on 25% 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 JFK just before it, using the tail number in the DOT file, 400 of 905 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 |
|---|---|
| B61601 | 25% |
| 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 B61601’s aircraft landed 15 or more minutes late is higher than the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves JFK late, does that still matter by the time it reaches FLL?
B61601 pushes back an average of 15.3 minutes late and reaches the gate at FLL an average of 9.1 minutes late. The 6.2 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. Its 24.5 minutes on the taxiways at JFK is about what any departure from the airport in that hour spends.
On arrival at FLL, B61601 spends 6.1 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 1.3 minutes shorter than a typical FLL arrival (7.4 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 FLL. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 17,235 departures from JFK scheduled in the clock hour B61601 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at FLL (278,720 flights), not just B61601’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. B61601 has one departure time, so this is what that time is worth.
On-time arrival rate. 17,235 departures from JFK are scheduled in the 1 PM–2 PM hour over the period, against 351,635 across the whole day.
B61601 is scheduled out of JFK at 1:00 PM, in the 1 PM–2 PM bank. Departures from JFK in that hour arrive on time 75.3% of the time against 77.0% across the airport’s whole day, so the hour B61601 leaves in is an ordinary one for JFK and explains nothing about its record either way.
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 B61601 run worse on particular days?
Wednesday is historically the most reliable day and Saturday the least, a gap of 6.1 percentage points.

When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
57 min late
against a median of 4 min early
B61601 has an average that understates its risk: a typical arrival is 4 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.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. B61601 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 926 records of B61601 operating JFK → FLL, 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.
