Why DL946 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

Does a late aircraft delay this flight?
How often the plane that flies DL946 comes in late, and what that does to the departure.
DL946 is usually the aircraft’s first flight of the day: the schedule gives it a median of 9.7 hours on the ground at LAX, so its “inbound” is mostly the aircraft’s arrival the evening before.
The aircraft flying DL946 came in 15 or more minutes late on 23% of the departures where its previous flight is known. There are not enough departures in both groups to say how the flight left after a late one and after an on-time one.
Each departure is matched to the flight the same aircraft flew into LAX just before it, using the tail number in the DOT file, 510 of 651 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 |
|---|---|
| DL946 | 23% |
| Network, same turn | 29% |
A night on the ground absorbs most of a late arrival, so a late inbound matters far less on a turn this long than on a same-day one.
The network row is every flight with a scheduled turn of 6 hours or more, usually overnight. How often DL946’s aircraft landed 15 or more minutes late is lower than the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves LAX late, does that still matter by the time it reaches AUS?
DL946 pushes back an average of 4.5 minutes late and reaches the gate at AUS an average of 1.0 minutes late. The 3.4 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 16.3 minutes on the taxiways at LAX, 1.3 minutes shorter than a typical LAX departure in the same hour.
On arrival at AUS, DL946 spends 9.4 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 1.2 minutes longer than a typical AUS arrival (8.3 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 AUS. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 36,629 departures from LAX scheduled in the clock hour DL946 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at AUS (272,531 flights), not just DL946’s own. More on taxi time.

The hour it leaves LAX
Part of any flight’s record belongs to the clock rather than to the flight. DL946 has one departure time, so this is what that time is worth.
On-time arrival rate. 36,629 departures from LAX are scheduled in the 7 AM–8 AM hour over the period, against 595,153 across the whole day.
DL946 is scheduled out of LAX at 7:35 AM, in the 7 AM–8 AM bank. Departures from LAX in that hour arrive on time 89.0% of the time against 81.4% across the airport’s whole day — the slot alone is worth 7.6 points better before anything about this particular flight is considered.
The two airport figures cover every departure from LAX 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 DL946 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. DL946 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 661 records of DL946 operating LAX → AUS, 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.
