How F94462 performs
742 operations, November 2023 – July 2026.
F94462 arrived on time 54.2% of the time, against 63.5% for all PHL → SJU flights, so this departure is 9.3 percentage points worse than the route as a whole. Against Frontier Airlines’ own flights on this route it is 2.8 points worse.
F94462’s scheduled departure has moved during the period FlyerIntel has on file: it typically left around 12:00 AM earlier on, and around 8:00 PM more recently — a 240-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 F94462 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
Share of the delay minutes US DOT attributed to each cause for F94462 on PHL → SJU. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies F94462 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, F94462 pushed back an average of 48 minutes late; when it came in on time or early, an average of 8 minutes late.
Each departure is matched to the flight the same aircraft flew into PHL just before it, using the tail number in the DOT file, 562 of 726 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 |
|---|---|---|---|
| F94462 | 37% | 67% | 19% |
| 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 F94462’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often F94462 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves PHL late, does that still matter by the time it reaches SJU?
On arrival at SJU, F94462 spends 8.5 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 2.4 minutes longer than a typical SJU arrival (6.2 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 SJU. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 401 departures from PHL scheduled in the clock hour F94462 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at SJU (109,607 flights), not just F94462’s own. More on taxi time.

The hour it leaves PHL
Part of any flight’s record belongs to the clock rather than to the flight. F94462 has one departure time, so this is what that time is worth.
On-time arrival rate. 401 departures from PHL are scheduled in the 11 PM–12 AM hour over the period, against 305,181 across the whole day.
F94462 is scheduled out of PHL at 11:59 PM, in the 11 PM–12 AM bank. Departures from PHL in that hour arrive on time 66.8% of the time against 76.2% across the airport’s whole day — the slot alone is worth 9.4 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from PHL 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.

When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
96 min late
against a median of 10 min late
F94462 has an average that understates its risk: a typical arrival is 10 min late, but the worst tenth are 86 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 |
|---|---|---|---|---|
| F91016 | Frontier Airlines | 66.2% | 3 min late | 682 |
| F94462 this flight | Frontier Airlines | 54.2% | 10 min late | 742 |
Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. F94462 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 742 records of F94462 operating PHL → SJU, 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.
