Why DL1486 runs late
Where US DOT attributed the delay minutes on this flight.
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
the inbound aircraft was late, so this flight started late

Does a late aircraft delay this flight?
How often the plane that flies DL1486 comes in late, and what that does to the departure.
DL1486 is usually the aircraft’s first flight of the day: the schedule gives it a median of 8.8 hours on the ground at TPA, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, DL1486 pushed back an average of 11 minutes late; when it came in on time or early, an average of 0 minutes late.
Each departure is matched to the flight the same aircraft flew into TPA just before it, using the tail number in the DOT file, 594 of 621 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 |
|---|---|---|---|
| DL1486 | 34% | 15% | 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 DL1486’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often DL1486 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves TPA late, does that still matter by the time it reaches ATL?
DL1486 pushes back an average of 3.9 minutes late and reaches the gate at ATL an average of 0.9 minutes late. The 3.0 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 16.7 minutes on the taxiways at TPA is about what any departure from the airport in that hour spends.
On arrival at ATL, DL1486 spends 10.8 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 1.2 minutes longer 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 26,402 departures from TPA scheduled in the clock hour DL1486 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 DL1486’s own. More on taxi time.

The hour it leaves TPA
Part of any flight’s record belongs to the clock rather than to the flight. DL1486 has one departure time, so this is what that time is worth.
On-time arrival rate. 26,402 departures from TPA are scheduled in the 7 AM–8 AM hour over the period, against 242,628 across the whole day.
DL1486 is scheduled out of TPA at 7:00 AM, in the 7 AM–8 AM bank. Departures from TPA in that hour arrive on time 89.6% of the time against 78.2% across the airport’s whole day — the slot alone is worth 11.4 points better before anything about this particular flight is considered.
The two airport figures cover every departure from TPA 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.

Because the same number has served different journeys, the statistics above describe only the route DL1486 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. DL1486 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 631 records of DL1486 operating TPA → 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.
