Why AA2563 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
the inbound aircraft was late, so this flight started late
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for AA2563 on AUS → DFW. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies AA2563 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, AA2563 pushed back an average of 4 minutes late; when it came in on time or early, an average of 1 minute late.
Each departure is matched to the flight the same aircraft flew into AUS just before it, using the tail number in the DOT file, 925 of 987 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 |
|---|---|---|---|
| AA2563 | 36% | 8% | 7% |
| Network, same turn | 33% | 24% | 11% |
The schedule leaves a long gap on the ground, which gives a late aircraft room to catch up before this flight pushes back.
The network row is every flight with a scheduled turn of 3 to 6 hours. How often AA2563’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often AA2563 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves AUS late, does that still matter by the time it reaches DFW?
AA2563 pushes back an average of 4.8 minutes late and reaches the gate at DFW an average of 1.4 minutes early. The 6.2 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. It spends 15.4 minutes on the taxiways at AUS, 1.4 minutes longer than a typical AUS departure in the same hour.
On arrival at DFW, AA2563 spends 10.4 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 3.1 minutes shorter than a typical DFW arrival (13.5 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 DFW. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 11,861 departures from AUS scheduled in the clock hour AA2563 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at DFW (961,642 flights), not just AA2563’s own. More on taxi time.

The hour it leaves AUS
Part of any flight’s record belongs to the clock rather than to the flight. AA2563 has one departure time, so this is what that time is worth.
On-time arrival rate. 11,861 departures from AUS are scheduled in the 5 AM–6 AM hour over the period, against 272,521 across the whole day.
AA2563 is scheduled out of AUS at 5:00 AM, in the 5 AM–6 AM bank. Departures from AUS in that hour arrive on time 93.8% of the time against 78.0% across the airport’s whole day — the slot alone is worth 15.8 points better before anything about this particular flight is considered.
The two airport figures cover every departure from AUS 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.

Same airports, same journey, different odds of arriving on time.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. AA2563 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 1,015 records of AA2563 operating AUS → DFW, 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.
