AA1777 is usually the aircraft’s first flight of the day: the schedule gives it a median of 9.2 hours on the ground at ATL, so its “inbound” is mostly the aircraft’s arrival the evening before.

When the aircraft came in 15 or more minutes late, AA1777 pushed back an average of 8 minutes late; when it came in on time or early, an average of 5 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, 522 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.

AA1777 pushes back an average of 9.3 minutes late and reaches the gate at PHX an average of 4.5 minutes late. The 4.8 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 16.5 minutes on the taxiways at ATL is about what any departure from the airport in that hour spends.

On arrival at PHX, AA1777 spends 11.8 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 4.3 minutes longer than a typical PHX arrival (7.5 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 PHX. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 80,028 departures from ATL scheduled in the clock hour AA1777 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at PHX (598,496 flights), not just AA1777’s own. More on taxi time.

AA1777 is scheduled out of ATL at 8:00 AM, in the 8 AM–9 AM bank. Departures from ATL in that hour arrive on time 88.0% of the time against 78.7% across the airport’s whole day — the slot alone is worth 9.3 points better 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 AA1777 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. AA1777 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.
