Why AA2403 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
screening or terminal security incidents

Does a late aircraft delay this flight?
How often the plane that flies AA2403 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, AA2403 pushed back an average of 51 minutes late; when it came in on time or early, an average of 12 minutes late.
Matched by tail number to the aircraft’s previous flight into DFW: 744 of 862 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 |
|---|---|---|---|
| AA2403 | 22% | 73% | 29% |
| Network, same turn | 17% | 69% | 9% |
64 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 AA2403’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often AA2403 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 ATL?
On arrival at ATL, AA2403 spends 9.9 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 ATL 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 66,125 DFW departures. Taxi-in is landing to gate, set against 1,039,387 arrivals at ATL. More on taxi time.
