Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| AA1174 | 69.9% | 3.35% | -3 min | 12.2% | 626 |
| American Airlines on JFK → MIA | 77.2% | 2.10% | -8 min | 9.6% | 8,964 |
| All JFK → MIA flights | 74.9% | 2.15% | -7 min | 10.4% | 16,209 |
AA1174 has cancelled 3.35% of its scheduled departures (21 of 626), against 2.15% for all JFK → MIA 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 AA1174 specifically, not about the route it flies.
12.2% of AA1174’s arrivals were an hour or more late, against 10.4% across JFK → MIA, so the long delays are more common on this number than on the route.

Why AA1174 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
crew, maintenance, boarding and fueling, all within the carrier’s 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 AA1174 comes in late, and what that does to the departure.
The aircraft flying AA1174 came in 15 or more minutes late on 29% 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.
Matched by tail number to the aircraft’s previous flight into JFK: 389 of 605 departures. Unknown, cancelled or diverted inbounds and gaps over 12 hours are left out.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late |
|---|---|
| AA1174 | 29% |
| Network, same turn | 23% |
A long gap on the ground gives a late aircraft room to catch up before this flight pushes back.
The network row is every flight with a scheduled turn of 90 minutes to 3 hours. How often AA1174’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 MIA?
AA1174 pushes back an average of 23.5 minutes late and reaches the gate at MIA an average of 18.7 minutes late. The 4.8 minutes between those two figures are slack the published schedule already carries, so a late pushback is partly, not fully, made up before the gate. It spends 30.9 minutes on the taxiways at JFK, 2.3 minutes shorter than a typical JFK departure in the same hour.
On arrival at MIA, AA1174 spends 11.0 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 longer than a typical MIA arrival (9.7 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 18,482 JFK departures. Taxi-in is landing to gate, set against 349,140 arrivals at MIA. More on taxi time.

The hour it leaves JFK
AA1174 has one departure time, 6:30 PM, so this is what that hour at JFK is worth.
On-time arrival rate. 18,482 departures from JFK are scheduled in the 6 PM–7 PM hour over the period, against 360,775 across the whole day.
AA1174 is scheduled out of JFK at 6:30 PM, in the 6 PM–7 PM bank. Departures from JFK in that hour arrive on time 67.4% of the time against 76.7% across the airport’s whole day — the slot alone is worth 9.3 points worse before anything about this particular flight is considered.
Both airport figures cover every destination from JFK, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.

When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
75 min late
against a median of 3 min early
AA1174 has an average that understates its risk: a typical arrival is 3 min early, but the worst tenth are 78 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 626 records of AA1174 operating JFK → MIA, 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 reported separately, not in the on-time rate.
