Share of the delay minutes US DOT attributed to each cause for AA2779 on ORD → ATL. Only delays of 15 minutes or more are attributed.

When the aircraft came in 15 or more minutes late, AA2779 pushed back an average of 80 minutes late; when it came in on time or early, an average of 10 minutes late.

Each departure is matched to the flight the same aircraft flew into ORD just before it, using the tail number in the DOT file, 639 of 712 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.

AA2779 pushes back an average of 45.2 minutes late and reaches the gate at ATL an average of 38.1 minutes late. The 7.0 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. It spends 20.9 minutes on the taxiways at ORD, 9.6 minutes shorter than a typical ORD departure in the same hour.

On arrival at ATL, AA2779 spends 9.9 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 ATL 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 ATL. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 81,342 departures from ORD scheduled in the clock hour AA2779 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 AA2779’s own. More on taxi time.

AA2779 is scheduled out of ORD at 6:20 PM, in the 6 PM–7 PM bank. Departures from ORD in that hour arrive on time 67.0% of the time against 74.5% across the airport’s whole day — the slot alone is worth 7.5 points worse before anything about this particular flight is considered.

The two airport figures cover every departure from ORD 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 AA2779 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. AA2779 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.
