Why AA1724 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

Does a late aircraft delay this flight?
How often the plane that flies AA1724 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, AA1724 pushed back an average of 50 minutes late; when it came in on time or early, an average of 10 minutes late.
Matched by tail number to the aircraft’s previous flight into DFW: 635 of 724 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 |
|---|---|---|---|
| AA1724 | 21% | 74% | 22% |
| Network, same turn | 17% | 69% | 9% |
66 scheduled minutes is enough to clean and board when the aircraft is on time, with little to spare when it is not.
The network row is every flight with a scheduled turn of 60 to 89 minutes. How often AA1724’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often AA1724 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves DFW late, does that still matter by the time it reaches BUF?
AA1724 pushes back an average of 27.3 minutes late and reaches the gate at BUF an average of 19.7 minutes late. The 7.7 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 18.6 minutes on the taxiways at DFW, 2.4 minutes shorter than a typical DFW departure in the same hour.
On arrival at BUF, AA1724 spends 6.4 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 BUF spends on the ground before reaching the gate.
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 74,302 DFW departures. Taxi-in is landing to gate, set against 67,460 arrivals at BUF. More on taxi time.

When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
71 min late
against a median of 2 min late
AA1724 has an average that understates its risk: a typical arrival is 2 min late, but the worst tenth are 69 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.
