Why UA1995 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
Share of the delay minutes US DOT attributed to each cause for UA1995 on SFO → LAS. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies UA1995 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, UA1995 pushed back an average of 31 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 SFO just before it, using the tail number in the DOT file, 664 of 780 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 |
|---|---|---|---|
| UA1995 | 22% | 51% | 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 UA1995’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often UA1995 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 LAS?
UA1995 pushes back an average of 9.0 minutes late and reaches the gate at LAS an average of 2.2 minutes late. The 6.8 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. Its 20.7 minutes on the taxiways at SFO is about what any departure from the airport in that hour spends.
On arrival at LAS, UA1995 spends 9.3 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 1.7 minutes longer than a typical LAS arrival (7.7 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 LAS. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 17,402 departures from SFO scheduled in the clock hour UA1995 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at LAS (569,643 flights), not just UA1995’s own. More on taxi time.

The hour it leaves SFO
Part of any flight’s record belongs to the clock rather than to the flight. UA1995 has one departure time, so this is what that time is worth.
On-time arrival rate. 17,402 departures from SFO are scheduled in the 7 PM–8 PM hour over the period, against 435,779 across the whole day.
UA1995 is scheduled out of SFO at 7:10 PM, in the 7 PM–8 PM bank. Departures from SFO in that hour arrive on time 75.9% of the time against 78.7% across the airport’s whole day, so the hour UA1995 leaves in is an ordinary one for SFO and explains nothing about its record either way.
The two airport figures cover every departure from SFO 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 UA1995 currently operates. Blending them would produce an average of two different flights.

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. UA1995 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 781 records of UA1995 operating SFO → LAS, 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.
