Why B62404 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
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 B62404 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, B62404 pushed back an average of 81 minutes late; when it came in on time or early, an average of 9 minutes late.
Each departure is matched to the flight the same aircraft flew into SJU just before it, using the tail number in the DOT file, 611 of 629 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 |
|---|---|---|---|
| B62404 | 30% | 85% | 17% |
| Network, same turn | 17% | 68% | 9% |
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 B62404’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often B62404 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves SJU late, does that still matter by the time it reaches JFK?
B62404 pushes back an average of 33.8 minutes late and reaches the gate at JFK an average of 25.3 minutes late. The 8.6 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 14.1 minutes on the taxiways at SJU, 2.9 minutes shorter than a typical SJU departure in the same hour.
On arrival at JFK, B62404 spends 9.4 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 2.0 minutes shorter than a typical JFK arrival (11.5 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 JFK. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 8,304 departures from SJU scheduled in the clock hour B62404 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at JFK (351,546 flights), not just B62404’s own. More on taxi time.

The hour it leaves SJU
Part of any flight’s record belongs to the clock rather than to the flight. B62404 has one departure time, so this is what that time is worth.
On-time arrival rate. 8,304 departures from SJU are scheduled in the 1 PM–2 PM hour over the period, against 109,598 across the whole day.
B62404 is scheduled out of SJU at 1:52 PM, in the 1 PM–2 PM bank. Departures from SJU in that hour arrive on time 75.7% of the time against 76.2% across the airport’s whole day, so the hour B62404 leaves in is an ordinary one for SJU and explains nothing about its record either way.
The two airport figures cover every departure from SJU 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.

Other routes B62404 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 |
|---|---|---|---|
| BQN→JFK Aguadilla to New York | June 13, 2024 – July 21, 2024 | 39 | — |
Because the same number has served different journeys, the statistics above describe only the route B62404 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.
103 min late
against a median of 1 min early
B62404 has an average that understates its risk: a typical arrival is 1 min early, but the worst tenth are 103 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. B62404 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 639 records of B62404 operating SJU → JFK, 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.
