What stands out
How DL926 compares to other flight numbers, not just to itself.
This flight runs unusually far ahead of the carrier's own average on this route, better than 92% of 11,589 comparable flight numbers.

Why DL926 runs late
Where US DOT attributed the delay minutes on this flight.
airspace and airport capacity, including weather-driven flow control
crew, maintenance, boarding and fueling, all within the carrier’s control
weather severe enough to stop this flight specifically
the inbound aircraft was late, so this flight started late
screening or terminal security incidents

Does a late aircraft delay this flight?
How often the plane that flies DL926 comes in late, and what that does to the departure.
DL926 is usually the aircraft’s first flight of the day: the schedule gives it a median of 8.5 hours on the ground at ATL, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, DL926 pushed back an average of 3 minutes late; when it came in on time or early, an average of 1 minute late.
Each departure is matched to the flight the same aircraft flew into ATL just before it, using the tail number in the DOT file, 640 of 766 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 |
|---|---|---|---|
| DL926 | 19% | 13% | 8% |
| Network, same turn | 29% | 12% | 9% |
A night on the ground absorbs most of a late arrival, so a late inbound matters far less on a turn this long than on a same-day one.
The network row is every flight with a scheduled turn of 6 hours or more, usually overnight. How often DL926’s aircraft landed 15 or more minutes late is lower than the network’s and, once the aircraft was late, how often DL926 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves ATL late, does that still matter by the time it reaches DCA?
DL926 pushes back an average of 2.1 minutes late and arrives a further 2.7 minutes behind that. This departure loses ground between the two gates rather than recovering it, so a late pushback here tends to get worse on the way, not better. It spends 19.7 minutes on the taxiways at ATL, 2.6 minutes longer than a typical ATL departure in the same hour.
On arrival at DCA, DL926 spends 6.4 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 1.3 minutes shorter than a typical DCA arrival (7.6 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 DCA. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 45,565 departures from ATL scheduled in the clock hour DL926 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at DCA (435,126 flights), not just DL926’s own. More on taxi time.

The hour it leaves ATL
Part of any flight’s record belongs to the clock rather than to the flight. DL926 has one departure time, so this is what that time is worth.
On-time arrival rate. 45,565 departures from ATL are scheduled in the 7 AM–8 AM hour over the period, against 1,012,247 across the whole day.
DL926 is scheduled out of ATL at 7:25 AM, in the 7 AM–8 AM bank. Departures from ATL in that hour arrive on time 87.6% of the time against 78.7% across the airport’s whole day — the slot alone is worth 8.8 points better before anything about this particular flight is considered.
The two airport figures cover every departure from ATL 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 DL926 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. DL926 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 789 records of DL926 operating ATL → DCA, 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.
