Why DL2030 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
the inbound aircraft was late, so this flight started late
weather severe enough to stop this flight specifically
screening or terminal security incidents

Does a late aircraft delay this flight?
How often the plane that flies DL2030 comes in late, and what that does to the departure.
The aircraft flying DL2030 came in 15 or more minutes late on 17% 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 DTW just before it, using the tail number in the DOT file, 646 of 667 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 |
|---|---|
| DL2030 | 17% |
| 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 DL2030’s aircraft landed 15 or more minutes late is about the same as the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves DTW late, does that still matter by the time it reaches DCA?
DL2030 pushes back an average of 20.0 minutes late and arrives a further 3.7 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 24.4 minutes on the taxiways at DTW, 6.4 minutes longer than a typical DTW departure in the same hour.
On arrival at DCA, DL2030 spends 6.2 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 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 15,998 departures from DTW scheduled in the clock hour DL2030 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 DL2030’s own. More on taxi time.

The hour it leaves DTW
Part of any flight’s record belongs to the clock rather than to the flight. DL2030 has one departure time, so this is what that time is worth.
On-time arrival rate. 15,998 departures from DTW are scheduled in the 5 PM–6 PM hour over the period, against 388,632 across the whole day.
DL2030 is scheduled out of DTW at 5:27 PM, in the 5 PM–6 PM bank. Departures from DTW in that hour arrive on time 69.9% of the time against 79.6% across the airport’s whole day — the slot alone is worth 9.7 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from DTW 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.

Other routes DL2030 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.

Because the same number has served different journeys, the statistics above describe only the route DL2030 currently operates. Blending them would produce an average of two different flights.
When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
89 min late
against a median of 7 min late
DL2030 has an average that understates its risk: a typical arrival is 7 min late, but the worst tenth are 82 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Same airports, same journey, different odds of arriving on time.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. DL2030 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 686 records of DL2030 operating DTW → 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.
