Why DL2736 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

Does a late aircraft delay this flight?
How often the plane that flies DL2736 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, DL2736 pushed back an average of 62 minutes late; when it came in on time or early, an average of 0 minutes early.
Matched by tail number to the aircraft’s previous flight into AUS: 594 of 619 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 |
|---|---|---|---|
| DL2736 | 20% | 78% | 9% |
| Network, same turn | 18% | 85% | 10% |
57 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 45 to 59 minutes. How often DL2736’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often DL2736 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves AUS late, does that still matter by the time it reaches DTW?
DL2736 pushes back an average of 22.0 minutes late and reaches the gate at DTW an average of 15.8 minutes late. The 6.1 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 16.7 minutes on the taxiways at AUS is about what any departure from the airport in that hour spends.
On arrival at DTW, DL2736 spends 10.8 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 1.4 minutes longer than a typical DTW arrival (9.3 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 19,572 AUS departures. Taxi-in is landing to gate, set against 398,786 arrivals at DTW. More on taxi time.

The hour it leaves AUS
DL2736 has one departure time, 4:40 PM, so this is what that hour at AUS is worth.
On-time arrival rate. 19,572 departures from AUS are scheduled in the 4 PM–5 PM hour over the period, against 280,096 across the whole day.
DL2736 is scheduled out of AUS at 4:40 PM, in the 4 PM–5 PM bank. Departures from AUS in that hour arrive on time 67.7% of the time against 77.9% across the airport’s whole day — the slot alone is worth 10.2 points worse before anything about this particular flight is considered.
Both airport figures cover every destination from AUS, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.
