Does a late aircraft delay this flight?
How often the plane that flies DL2872 comes in late, and what that does to the departure.
DL2872 is usually the aircraft’s first flight of the day: the schedule gives it a median of 6.3 hours on the ground at BWI, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, DL2872 pushed back an average of 3 minutes late; when it came in on time or early, an average of 2 minutes late.
Each departure is matched to the flight the same aircraft flew into BWI just before it, using the tail number in the DOT file, 1,041 of 1,050 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 |
|---|---|---|---|
| DL2872 | 22% | 10% | 7% |
| 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 DL2872’s aircraft landed 15 or more minutes late is lower than the network’s and, once the aircraft was late, how often DL2872 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves BWI late, does that still matter by the time it reaches MSP?
DL2872 pushes back an average of 2.6 minutes late and reaches the gate at MSP an average of 4.7 minutes early. The 7.3 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 15.4 minutes on the taxiways at BWI is about what any departure from the airport in that hour spends.
On arrival at MSP, DL2872 spends 6.1 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 about what any arrival at MSP spends on the ground before reaching the gate.
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 MSP. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 28,419 departures from BWI scheduled in the clock hour DL2872 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at MSP (369,815 flights), not just DL2872’s own. More on taxi time.

The hour it leaves BWI
Part of any flight’s record belongs to the clock rather than to the flight. DL2872 has one departure time, so this is what that time is worth.
On-time arrival rate. 28,419 departures from BWI are scheduled in the 6 AM–7 AM hour over the period, against 299,178 across the whole day.
DL2872 is scheduled out of BWI at 6:00 AM, in the 6 AM–7 AM bank. Departures from BWI in that hour arrive on time 90.2% of the time against 76.0% across the airport’s whole day — the slot alone is worth 14.3 points better before anything about this particular flight is considered.
The two airport figures cover every departure from BWI 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 DL2872 run worse on particular days?
Wednesday is historically the most reliable day and Friday the least, a gap of 5.9 percentage points.

Other routes DL2872 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.
| Route | Operated | Flights | On time |
|---|---|---|---|
| ATL→HOU Atlanta to Houston | July 5, 2023 – September 4, 2023 | 59 | — |
| HOU→ATL Houston to Atlanta | July 5, 2023 – September 4, 2023 | 59 | — |
| ATL→EWR Atlanta to Newark | July 2–7, 2023 | 5 | — |
Because the same number has served different journeys, the statistics above describe only the route DL2872 currently operates. Blending them would produce an average of two different flights.

Data and methodology
Calculated by FlyerIntel from 1,061 records of DL2872 operating BWI → MSP, 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.
