Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| DL2888 | 80.5% | 0.82% | -9 min | 7.9% | 611 |
| Delta Air Lines on MIA → DCA | 81.1% | 0.87% | -10 min | 7.9% | 1,029 |
| All MIA → DCA flights | 74.7% | 2.01% | -5 min | 9.1% | 12,308 |
DL2888 has cancelled 0.82% of its scheduled departures (5 of 611), against 2.01% for all MIA → DCA flights — this specific departure cancels 1.2 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 DL2888 specifically, not about the route it flies.

Why DL2888 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for DL2888 on MIA → DCA. Only delays of 15 minutes or more are attributed. What the five causes mean

Does a late aircraft delay this flight?
How often the plane that flies DL2888 comes in late, and what that does to the departure.
The aircraft flying DL2888 came in 15 or more minutes late on 13% 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.
Matched by tail number to the aircraft’s previous flight into MIA: 584 of 606 departures. Unknown, cancelled or diverted inbounds and gaps over 12 hours are left out.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late |
|---|---|
| DL2888 | 13% |
| Network, same turn | 18% |
56 scheduled minutes is enough to clean and board when the aircraft is on time, with little to spare when it is not.
The network row is every flight with a scheduled turn of 45 to 59 minutes. How often DL2888’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 MIA late, does that still matter by the time it reaches DCA?
DL2888 pushes back an average of 11.1 minutes late and reaches the gate at DCA an average of 6.1 minutes late. The 5.0 minutes between those two figures are slack the published schedule already carries, so a late pushback is partly, not fully, made up before the gate. It spends 25.0 minutes on the taxiways at MIA, 2.6 minutes longer than a typical MIA departure in the same hour.
On arrival at DCA, DL2888 spends 5.7 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 1.9 minutes shorter than a typical DCA arrival (7.7 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 12,569 MIA departures. Taxi-in is landing to gate, set against 447,280 arrivals at DCA. More on taxi time.

The hour it leaves MIA
DL2888 has one departure time, 11:10 AM, so this is what that hour at MIA is worth.
On-time arrival rate. 12,569 departures from MIA are scheduled in the 11 AM–12 PM hour over the period, against 349,146 across the whole day.
DL2888 is scheduled out of MIA at 11:10 AM, in the 11 AM–12 PM bank. Departures from MIA in that hour arrive on time 76.6% of the time against 73.2% across the airport’s whole day — the slot alone is worth 3.4 points better before anything about this particular flight is considered.
Both airport figures cover every destination from MIA, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.

Data and methodology
Calculated by FlyerIntel from 611 records of DL2888 operating MIA → 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 reported separately, not in the on-time rate.
