Why UA1107 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control

Does a late aircraft delay this flight?
How often the plane that flies UA1107 comes in late, and what that does to the departure.
UA1107 is usually the aircraft’s first flight of the day: the schedule gives it a median of 9.2 hours on the ground at SFO, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, UA1107 pushed back an average of 0 minutes late; when it came in on time or early, an average of 3 minutes early.
Matched by tail number to the aircraft’s previous flight into SFO: 655 of 913 departures. Unknown, cancelled or diverted inbounds and gaps over 12 hours are left out.
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 |
|---|---|---|---|
| UA1107 | 20% | 7% | 5% |
| Network, same turn | 29% | 12% | 9% |
A night on the ground absorbs most of a late arrival, so a late inbound matters far less here than on a same-day turn.
The network row is every flight with a scheduled turn of 6 hours or more, usually overnight. How often UA1107’s aircraft landed 15 or more minutes late is lower than the network’s and, once the aircraft was late, how often UA1107 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves SFO late, does that still matter by the time it reaches AUS?
UA1107 pushes back an average of 0.9 minutes early and reaches the gate at AUS an average of 6.7 minutes early. The 5.8 minutes between those two figures are slack the published schedule already carries. It spends 21.4 minutes on the taxiways at SFO, 2.3 minutes longer than a typical SFO departure in the same hour.
On arrival at AUS, UA1107 spends 7.4 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 about what any arrival at AUS spends on the ground before reaching the gate.
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 24,387 SFO departures. Taxi-in is landing to gate, set against 280,105 arrivals at AUS. More on taxi time.

The hour it leaves SFO
UA1107 has one departure time, 7:00 AM, so this is what that hour at SFO is worth.
On-time arrival rate. 24,387 departures from SFO are scheduled in the 7 AM–8 AM hour over the period, against 449,339 across the whole day.
UA1107 is scheduled out of SFO at 7:00 AM, in the 7 AM–8 AM bank. Departures from SFO in that hour arrive on time 90.1% of the time against 78.3% across the airport’s whole day — the slot alone is worth 11.8 points better before anything about this particular flight is considered.
Both airport figures cover every destination from SFO, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.

By day of week
Does UA1107 run worse on particular days?

Data and methodology
Calculated by FlyerIntel from 919 records of UA1107 operating SFO → 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 reported separately, not in the on-time rate.
