DL1548 pushes back an average of 1.8 minutes late and reaches the gate at ATL an average of 8.3 minutes early. The 10.1 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 14.6 minutes on the taxiways at MCO is about what any departure from the airport in that hour spends.

On arrival at ATL, DL1548 spends 6.7 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 2.8 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 10,440 departures from MCO scheduled in the clock hour DL1548 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 DL1548’s own. More on taxi time.

DL1548 is scheduled out of MCO at 5:30 AM, in the 5 AM–6 AM bank. Departures from MCO in that hour arrive on time 92.5% of the time against 74.8% across the airport’s whole day — the slot alone is worth 17.8 points better before anything about this particular flight is considered.

The two airport figures cover every departure from MCO 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 DL1548 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. DL1548 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.
