Why UA1992 runs late
Where US DOT attributed the delay minutes on this flight.
airspace and airport capacity, including weather-driven flow control
the inbound aircraft was late, so this flight started late
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 UA1992 on EWR → IAD. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies UA1992 comes in late, and what that does to the departure.
The aircraft flying UA1992 came in 15 or more minutes late on 15% 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 EWR just before it, using the tail number in the DOT file, 646 of 824 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 |
|---|---|
| UA1992 | 15% |
| Network, same turn | 17% |
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 UA1992’s aircraft landed 15 or more minutes late is about the same as the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves EWR late, does that still matter by the time it reaches IAD?
UA1992 pushes back an average of 21.2 minutes late and arrives a further 3.3 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 29.9 minutes on the taxiways at EWR, 5.6 minutes longer than a typical EWR departure in the same hour.
On arrival at IAD, UA1992 spends 7.8 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 IAD spends on the ground before reaching the gate.
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 IAD. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 23,662 departures from EWR scheduled in the clock hour UA1992 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at IAD (169,930 flights), not just UA1992’s own. More on taxi time.

The hour it leaves EWR
Part of any flight’s record belongs to the clock rather than to the flight. UA1992 has one departure time, so this is what that time is worth.
On-time arrival rate. 23,662 departures from EWR are scheduled in the 3 PM–4 PM hour over the period, against 387,621 across the whole day.
UA1992 is scheduled out of EWR at 3:00 PM, in the 3 PM–4 PM bank. Departures from EWR in that hour arrive on time 74.3% of the time against 77.7% across the airport’s whole day — the slot alone is worth 3.4 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from EWR 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.

By day of week
Does UA1992 run worse on particular days?
Tuesday is historically the most reliable day and Friday the least, a gap of 9.7 percentage points.

Because the same number has served different journeys, the statistics above describe only the route UA1992 currently operates. Blending them would produce an average of two different flights.
When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
80 min late
against a median of 6 min late
UA1992 has an average that understates its risk: a typical arrival is 6 min late, but the worst tenth are 74 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Data and methodology
Calculated by FlyerIntel from 836 records of UA1992 operating EWR → IAD, 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.
