DL380
Atlanta (ATL) to Washington (DCA) · scheduled 9:40 AM – 11:00 AM
How DL380 performs
1,033 operations, September 2023 – July 2026.
DL380 arrived on time 82.8% of the time, against 73.7% for all ATL → DCA flights, so this departure is 9.1 percentage points better than the route as a whole. Against Delta Air Lines’ own flights on this route it is 11.4 points better.
DL380’s scheduled departure has moved during the period FlyerIntel has on file: it typically left around 9:15 AM earlier on, and around 9:45 AM more recently — a 30-minute shift, not the few minutes of day-to-day rounding every published schedule carries. Confirm the current departure time before booking around an older listing.

What stands out
How DL380 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 94% of 11,589 comparable flight numbers.
82.8% on time for this specific departure, against 71.4% for the same carrier's other flights on this route.

Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| DL380 | 82.8% | 1.16% | -5 min | 3.6% | 1,033 |
| Delta Air Lines on ATL → DCA | 71.4% | 1.77% | 0 min | 8.8% | 11,809 |
| All ATL → DCA flights | 73.7% | 2.31% | -2 min | 8.9% | 21,171 |
DL380 has cancelled 1.16% of its scheduled departures (12 of 1,033), against 2.31% for all ATL → DCA flights — this specific departure cancels 1.1 percentage points less often than the route as a whole. Different flight numbers on the same route can carry different aircraft, crews and schedules, so this is a fact about DL380 specifically, not about the route it flies.

Why DL380 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
the inbound aircraft was late, so this flight started late
weather severe enough to stop this flight specifically

Does a late aircraft delay this flight?
How often the plane that flies DL380 comes in late, and what that does to the departure.
The aircraft flying DL380 came in 15 or more minutes late on 9% of the departures where its previous flight is known. There are not enough departures in both groups to say how the flight left after a late one and after an on-time one.
Each departure is matched to the flight the same aircraft flew into ATL just before it, using the tail number in the DOT file, 927 of 1,021 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 |
|---|---|
| DL380 | 9% |
| Network, same turn | 17% |
The schedule leaves a normal turn: enough time to clean and board if the aircraft is on time, little to spare if it is not.
The network row is every flight with a scheduled turn of 60 to 89 minutes. How often DL380’s aircraft landed 15 or more minutes late is lower than the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves ATL late, does that still matter by the time it reaches DCA?
DL380 pushes back an average of 5.9 minutes late and reaches the gate at DCA an average of 2.5 minutes late. The 3.4 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. Its 17.4 minutes on the taxiways at ATL is about what any departure from the airport in that hour spends.
On arrival at DCA, DL380 spends 4.9 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 2.7 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 74,879 departures from ATL scheduled in the clock hour DL380 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 DL380’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. DL380 has one departure time, so this is what that time is worth.
On-time arrival rate. 74,879 departures from ATL are scheduled in the 9 AM–10 AM hour over the period, against 1,012,247 across the whole day.
DL380 is scheduled out of ATL at 9:40 AM, in the 9 AM–10 AM bank. Departures from ATL in that hour arrive on time 84.6% of the time against 78.7% across the airport’s whole day — the slot alone is worth 5.9 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.

By day of week
Does DL380 run worse on particular days?
Tuesday is historically the most reliable day and Sunday the least, a gap of 11.4 percentage points.

Other routes DL380 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.

| DCA→ATL Washington to Atlanta | September 5, 2023 – July 31, 2026 | 869 | 82.7% |

Because the same number has served different journeys, the statistics above describe only the route DL380 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. DL380 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 1,033 records of DL380 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.
