Why UA1326 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
crew, maintenance, boarding and fueling, all within the carrier’s control
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for UA1326 on AUS → IAH. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies UA1326 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, UA1326 pushed back an average of 61 minutes late; when it came in on time or early, an average of 4 minutes 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, 785 of 794 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 |
|---|---|---|---|
| UA1326 | 19% | 71% | 9% |
| Network, same turn | 17% | 68% | 9% |
The schedule leaves a normal turn: enough time to clean and board if the aircraft is on time, little to spare if it is not.
The network row is every flight with a scheduled turn of 60 to 89 minutes. How often UA1326’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often UA1326 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves AUS late, does that still matter by the time it reaches IAH?
UA1326 pushes back an average of 15.7 minutes late and arrives a further 4.5 minutes behind that. This departure loses ground between the two gates rather than recovering it, so a late pushback here tends to get worse on the way, not better. It spends 23.2 minutes on the taxiways at AUS, 7.5 minutes longer than a typical AUS departure in the same hour.
On arrival at IAH, UA1326 spends 13.4 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 2.8 minutes longer than a typical IAH arrival (10.7 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 IAH. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 16,523 departures from AUS scheduled in the clock hour UA1326 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at IAH (359,471 flights), not just UA1326’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. UA1326 has one departure time, so this is what that time is worth.
On-time arrival rate. 16,523 departures from AUS are scheduled in the 5 PM–6 PM hour over the period, against 272,521 across the whole day.
UA1326 is scheduled out of AUS at 5:59 PM, in the 5 PM–6 PM bank. Departures from AUS in that hour arrive on time 67.0% of the time against 78.0% across the airport’s whole day — the slot alone is worth 11.0 points worse 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.

Because the same number has served different journeys, the statistics above describe only the route UA1326 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. UA1326 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 804 records of UA1326 operating AUS → IAH, 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.
