Why AA1727 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 AA1727 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, AA1727 pushed back an average of 55 minutes late; when it came in on time or early, an average of 14 minutes late.
Each departure is matched to the flight the same aircraft flew into CLT just before it, using the tail number in the DOT file, 845 of 1,078 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 |
|---|---|---|---|
| AA1727 | 29% | 70% | 26% |
| 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 AA1727’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often AA1727 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves CLT late, does that still matter by the time it reaches JFK?
On arrival at JFK, AA1727 spends 11.9 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 about what any arrival at JFK spends on the ground before reaching the gate.
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 56,899 departures from CLT scheduled in the clock hour AA1727 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 AA1727’s own. More on taxi time.

The hour it leaves CLT
Part of any flight’s record belongs to the clock rather than to the flight. AA1727 has one departure time, so this is what that time is worth.
On-time arrival rate. 56,899 departures from CLT are scheduled in the 8 PM–9 PM hour over the period, against 618,243 across the whole day.
AA1727 is scheduled out of CLT at 8:29 PM, in the 8 PM–9 PM bank. Departures from CLT in that hour arrive on time 64.8% of the time against 74.8% across the airport’s whole day — the slot alone is worth 10.0 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from CLT 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 AA1727 run worse on particular days?
Tuesday is historically the most reliable day and Sunday the least, a gap of 16.8 percentage points.

Other routes AA1727 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 |
|---|---|---|---|
| PHX→MSP Phoenix to Minneapolis | December 20, 2025 | 1 | — |
Because the same number has served different journeys, the statistics above describe only the route AA1727 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.
101 min late
against a median of 9 min late
AA1727 has an average that understates its risk: a typical arrival is 9 min late, but the worst tenth are 92 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 |
|---|---|---|---|---|

| AA1727 this flight | American Airlines | 56.5% | 9 min late | 1,102 |
Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. AA1727 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 1,102 records of AA1727 operating CLT → 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.
