Why DL3177 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 DL3177 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, DL3177 pushed back an average of 42 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 ATL: 585 of 604 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 |
|---|---|---|---|
| DL3177 | 21% | 56% | 10% |
| Network, same turn | 17% | 69% | 9% |
77 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 DL3177’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often DL3177 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves ATL late, does that still matter by the time it reaches CLT?
DL3177 pushes back an average of 10.8 minutes late and reaches the gate at CLT an average of 4.6 minutes late. The 6.2 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 15.9 minutes on the taxiways at ATL is about what any departure from the airport in that hour spends.
On arrival at CLT, DL3177 spends 8.8 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 4.0 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 73,766 ATL departures. Taxi-in is landing to gate, set against 633,359 arrivals at CLT. More on taxi time.

The hour it leaves ATL
DL3177 has one departure time, 10:40 PM, so this is what that hour at ATL is worth.
On-time arrival rate. 73,766 departures from ATL are scheduled in the 10 PM–11 PM hour over the period, against 1,039,468 across the whole day.
DL3177 is scheduled out of ATL at 10:40 PM, in the 10 PM–11 PM bank. Departures from ATL in that hour arrive on time 75.3% of the time against 78.6% across the airport’s whole day — the slot alone is worth 3.3 points worse before anything about this particular flight is considered.
Both airport figures cover every destination from ATL, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.
