Does a late aircraft delay this flight?
How often the plane that flies DL2183 comes in late, and what that does to the departure.
DL2183 is usually the aircraft’s first flight of the day: the schedule gives it a median of 7.1 hours on the ground at DFW, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, DL2183 pushed back an average of 6 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 DFW just before it, using the tail number in the DOT file, 1,036 of 1,054 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 |
|---|---|---|---|
| DL2183 | 27% | 8% | 6% |
| 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 DL2183’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often DL2183 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves DFW late, does that still matter by the time it reaches DTW?
DL2183 pushes back an average of 3.3 minutes late and reaches the gate at DTW an average of 1.5 minutes early. The 4.8 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. Its 16.5 minutes on the taxiways at DFW is about what any departure from the airport in that hour spends.
On arrival at DTW, DL2183 spends 10.5 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 1.1 minutes longer than a typical DTW arrival (9.3 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 DTW. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 12,571 departures from DFW scheduled in the clock hour DL2183 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at DTW (388,616 flights), not just DL2183’s own. More on taxi time.

The hour it leaves DFW
Part of any flight’s record belongs to the clock rather than to the flight. DL2183 has one departure time, so this is what that time is worth.
On-time arrival rate. 12,571 departures from DFW are scheduled in the 5 AM–6 AM hour over the period, against 961,718 across the whole day.
DL2183 is scheduled out of DFW at 5:30 AM, in the 5 AM–6 AM bank. Departures from DFW in that hour arrive on time 87.9% of the time against 73.1% across the airport’s whole day — the slot alone is worth 14.8 points better before anything about this particular flight is considered.
The two airport figures cover every departure from DFW 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 DL2183 run worse on particular days?
Wednesday is historically the most reliable day and Monday the least, a gap of 3.5 percentage points.

Other routes DL2183 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 |
|---|---|---|---|
| SAN→SEA San Diego to Seattle | January 8, 2024 – March 9, 2024 | 62 | — |
Because the same number has served different journeys, the statistics above describe only the route DL2183 currently operates. Blending them would produce an average of two different flights.

Other flights on this route
Same airports, same journey, different odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|
| DL2183 this flight | Delta Air Lines | 92.1% | 11 min early | 1,065 |

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. DL2183 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 1,065 records of DL2183 operating DFW → DTW, 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.
