Why AA1624 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 AA1624 comes in late, and what that does to the departure.
The aircraft flying AA1624 came in 15 or more minutes late on 12% 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 DFW: 530 of 613 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 |
|---|---|
| AA1624 | 12% |
| Network, same turn | 17% |
71 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 AA1624’s aircraft landed 15 or more minutes late is lower than the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves DFW late, does that still matter by the time it reaches DCA?
AA1624 pushes back an average of 11.9 minutes late and reaches the gate at DCA an average of 3.2 minutes late. The 8.7 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. Its 19.7 minutes on the taxiways at DFW is about what any departure from the airport in that hour spends.
On arrival at DCA, AA1624 spends 5.4 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 2.3 minutes shorter than a typical DCA arrival (7.7 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 33,819 DFW departures. Taxi-in is landing to gate, set against 447,280 arrivals at DCA. More on taxi time.
