Why AA1731 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
the inbound aircraft was late, so this flight started late
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 AA1731 comes in late, and what that does to the departure.
AA1731 is usually the aircraft’s first flight of the day: the schedule gives it a median of 8 hours on the ground at CHS, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, AA1731 pushed back an average of 11 minutes late; when it came in on time or early, an average of 2 minutes late.
Matched by tail number to the aircraft’s previous flight into CHS: 906 of 933 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 | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| AA1731 | 27% | 16% | 3% |
| Network, same turn | 29% | 12% | 9% |
A night on the ground usually absorbs a late arrival, but this flight has passed a late inbound on more often than the network does.
The network row is every flight with a scheduled turn of 6 hours or more, usually overnight. How often AA1731’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often AA1731 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves CHS late, does that still matter by the time it reaches CLT?
AA1731 pushes back an average of 4.3 minutes late and reaches the gate at CLT an average of 0.7 minutes late. The 3.6 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 17.9 minutes on the taxiways at CHS, 3.3 minutes longer than a typical CHS departure in the same hour.
On arrival at CLT, AA1731 spends 10.0 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 2.8 minutes shorter than a typical CLT arrival (12.8 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 8,887 CHS departures. Taxi-in is landing to gate, set against 633,359 arrivals at CLT. More on taxi time.

The hour it leaves CHS
AA1731 has one departure time, 6:45 AM, so this is what that hour at CHS is worth.
On-time arrival rate. 8,887 departures from CHS are scheduled in the 6 AM–7 AM hour over the period, against 79,421 across the whole day.
AA1731 is scheduled out of CHS at 6:45 AM, in the 6 AM–7 AM bank. Departures from CHS in that hour arrive on time 91.7% of the time against 80.4% across the airport’s whole day — the slot alone is worth 11.3 points better before anything about this particular flight is considered.
Both airport figures cover every destination from CHS, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.

Data and methodology
Calculated by FlyerIntel from 953 records of AA1731 operating CHS → CLT, 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.
