What stands out
How DL2836 compares to other flight numbers, not just to itself.
Which day you fly matters unusually much here, a wider weekday spread than 95% of 1,710 comparable flight numbers.
90.4% on time on a typical Monday, against 71.0% on a Sunday.

Why DL2836 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
the inbound aircraft was late, so this flight started late
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 DL2836 on MIA → ATL. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies DL2836 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, DL2836 pushed back an average of 47 minutes late; when it came in on time or early, an average of 3 minutes late.
Each departure is matched to the flight the same aircraft flew into MIA just before it, using the tail number in the DOT file, 886 of 929 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 |
|---|---|---|---|
| DL2836 | 17% | 80% | 7% |
| Network, same turn | 17% | 68% | 9% |
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 DL2836’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often DL2836 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves MIA late, does that still matter by the time it reaches ATL?
DL2836 pushes back an average of 14.3 minutes late and reaches the gate at ATL an average of 8.7 minutes late. The 5.7 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. It spends 26.2 minutes on the taxiways at MIA, 2.4 minutes longer than a typical MIA departure in the same hour.
On arrival at ATL, DL2836 spends 7.6 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 2.0 minutes shorter than a typical ATL arrival (9.6 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 ATL. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 11,247 departures from MIA scheduled in the clock hour DL2836 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at ATL (1,012,161 flights), not just DL2836’s own. More on taxi time.

The hour it leaves MIA
Part of any flight’s record belongs to the clock rather than to the flight. DL2836 has one departure time, so this is what that time is worth.
On-time arrival rate. 11,247 departures from MIA are scheduled in the 10 AM–11 AM hour over the period, against 340,469 across the whole day.
DL2836 is scheduled out of MIA at 10:28 AM, in the 10 AM–11 AM bank. Departures from MIA in that hour arrive on time 81.0% of the time against 73.2% across the airport’s whole day — the slot alone is worth 7.8 points better before anything about this particular flight is considered.
The two airport figures cover every departure from MIA 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 DL2836 run worse on particular days?
Monday is historically the most reliable day and Sunday the least, a gap of 19.4 percentage points.

Because the same number has served different journeys, the statistics above describe only the route DL2836 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. DL2836 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 940 records of DL2836 operating MIA → ATL, 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.
