How AA1864 performs
1,081 operations, July 2023 – July 2026.
AA1864 arrived on time 68.7% of the time, against 73.7% for all PHL → FLL flights, so this departure is 5.0 percentage points worse than the route as a whole. Against American Airlines’ own flights on this route it is 5.8 points worse.

Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| AA1864 | 68.7% | 3.42% | -4 min | 13.5% | 1,081 |
| American Airlines on PHL → FLL | 74.5% | 2.07% | -7 min | 11.2% | 4,001 |
| All PHL → FLL flights | 73.7% | 2.18% | -7 min | 11.1% | 8,837 |
AA1864 has cancelled 3.42% of its scheduled departures (37 of 1,081), against 2.18% for all PHL → FLL flights — this specific departure cancels 1.2 percentage points more often than the route as a whole. Different flight numbers on the same route can carry different aircraft, crews and schedules, so this is a fact about AA1864 specifically, not about the route it flies.

Why AA1864 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 AA1864 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, AA1864 pushed back an average of 49 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, 833 of 1,047 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 |
|---|---|---|---|
| AA1864 | 28% | 65% | 20% |
| 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 AA1864’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often AA1864 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves PHL late, does that still matter by the time it reaches FLL?
AA1864 pushes back an average of 24.8 minutes late and reaches the gate at FLL an average of 15.2 minutes late. The 9.6 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 23.3 minutes on the taxiways at PHL, 4.5 minutes shorter than a typical PHL departure in the same hour.
On arrival at FLL, AA1864 spends 4.8 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 2.6 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 24,665 departures from PHL scheduled in the clock hour AA1864 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 AA1864’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. AA1864 has one departure time, so this is what that time is worth.
On-time arrival rate. 24,665 departures from PHL are scheduled in the 7 PM–8 PM hour over the period, against 305,181 across the whole day.
AA1864 is scheduled out of PHL at 7:00 PM, in the 7 PM–8 PM bank. Departures from PHL in that hour arrive on time 65.2% of the time against 76.2% across the airport’s whole day — the slot alone is worth 11.1 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.

By day of week
Does AA1864 run worse on particular days?
Tuesday is historically the most reliable day and Thursday the least, a gap of 13.3 percentage points.

When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
72 min late
against a median of 4 min early
AA1864 has an average that understates its risk: a typical arrival is 4 min early, but the worst tenth are 76 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Data and methodology
Calculated by FlyerIntel from 1,081 records of AA1864 operating PHL → 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.
