Share of the delay minutes US DOT attributed to each cause for DL1457 on ATL → TPA. Only delays of 15 minutes or more are attributed.

When the aircraft came in 15 or more minutes late, DL1457 pushed back an average of 47 minutes late; when it came in on time or early, an average of 9 minutes late.

Each departure is matched to the flight the same aircraft flew into ATL just before it, using the tail number in the DOT file, 816 of 935 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.

DL1457 pushes back an average of 20.4 minutes late and reaches the gate at TPA an average of 18.2 minutes late. The 2.2 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 16.9 minutes on the taxiways at ATL is about what any departure from the airport in that hour spends.

On arrival at TPA, DL1457 spends 6.3 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 TPA 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 TPA. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 48,346 departures from ATL scheduled in the clock hour DL1457 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at TPA (242,635 flights), not just DL1457’s own. More on taxi time.

DL1457 is scheduled out of ATL at 6:25 PM, in the 6 PM–7 PM bank. Departures from ATL in that hour arrive on time 71.1% of the time against 78.7% across the airport’s whole day — the slot alone is worth 7.6 points worse before anything about this particular flight is considered.

The two airport figures cover every departure from ATL 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 DL1457 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. DL1457 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.
