Why DL1269 runs late
Where US DOT attributed the delay minutes on this flight.
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
the inbound aircraft was late, so this flight started late
Share of the delay minutes US DOT attributed to each cause for DL1269 on PHL → ATL. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies DL1269 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, DL1269 pushed back an average of 17 minutes late; when it came in on time or early, an average of 2 minutes early.
Each departure is matched to the flight the same aircraft flew into PHL just before it, using the tail number in the DOT file, 655 of 678 departures in all. A departure is left out when that flight is unknown, was cancelled or diverted, or the aircraft had sat for more than 12 hours. A flight the airline cancelled never left and is not in the count, and one flown by a substitute aircraft is matched to the aircraft that flew it, not to the one first planned.
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 |
|---|---|---|---|
| DL1269 | 31% | 16% | 4% |
| Network, same turn | 33% | 24% | 11% |
The schedule leaves a long gap on the ground, which gives a late aircraft room to catch up before this flight pushes back.
The network row is every flight with a scheduled turn of 3 to 6 hours. How often DL1269’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often DL1269 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves PHL late, does that still matter by the time it reaches ATL?
DL1269 pushes back an average of 5.5 minutes late and reaches the gate at ATL an average of 4.2 minutes early. The 9.8 minutes between those two figures are slack the published schedule already carries, which is why a late pushback on this flight does not reliably become a late arrival. It spends 14.5 minutes on the taxiways at PHL, 2.0 minutes shorter than a typical PHL departure in the same hour.
On arrival at ATL, DL1269 spends 8.3 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 1.3 minutes shorter than a typical ATL arrival (9.6 min).
Departure delay is averaged over every pushback and arrival delay over every completed arrival, so the two counts differ by the flights that never reached ATL. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 8,570 departures from PHL scheduled in the clock hour DL1269 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at ATL (1,012,161 flights), not just DL1269’s own. More on taxi time.

The hour it leaves PHL
Part of any flight’s record belongs to the clock rather than to the flight. DL1269 has one departure time, so this is what that time is worth.
On-time arrival rate. 8,570 departures from PHL are scheduled in the 5 AM–6 AM hour over the period, against 305,181 across the whole day.
DL1269 is scheduled out of PHL at 5:30 AM, in the 5 AM–6 AM bank. Departures from PHL in that hour arrive on time 89.1% of the time against 76.2% across the airport’s whole day — the slot alone is worth 12.8 points better before anything about this particular flight is considered.
The two airport figures cover every departure from PHL to every destination, so they describe the slot rather than this journey — the like-for-like comparison against the route is above. Hours are scheduled local, and a number whose schedule moved between banks inside the period has no single hour and is not described here at all. Why the hour matters.

Because the same number has served different journeys, the statistics above describe only the route DL1269 currently operates. Blending them would produce an average of two different flights.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. DL1269 is placed in the same ordering rather than left out of it; the rows around it are the most punctual departures on the route, not all of them, so this is a comparison and not a rank. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 693 records of DL1269 operating PHL → ATL, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
