Why UA2191 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
weather severe enough to stop this flight specifically

Does a late aircraft delay this flight?
How often the plane that flies UA2191 comes in late, and what that does to the departure.
The aircraft flying UA2191 came in 15 or more minutes late on 12% 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, 292 of 642 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 |
|---|---|
| UA2191 | 12% |
| Network, same turn | 23% |
The schedule leaves a long gap on the ground, which gives a late aircraft room to catch up before this flight pushes back.
The network row is every flight with a scheduled turn of 90 minutes to 3 hours. How often UA2191’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 EWR late, does that still matter by the time it reaches LAX?
UA2191 pushes back an average of 19.9 minutes late and reaches the gate at LAX an average of 9.4 minutes late. The 10.5 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 22.4 minutes on the taxiways at EWR is about what any departure from the airport in that hour spends.
On arrival at LAX, UA2191 spends 10.0 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 LAX 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 LAX. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 23,431 departures from EWR scheduled in the clock hour UA2191 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at LAX (595,170 flights), not just UA2191’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. UA2191 has one departure time, so this is what that time is worth.
On-time arrival rate. 23,431 departures from EWR are scheduled in the 2 PM–3 PM hour over the period, against 387,621 across the whole day.
UA2191 is scheduled out of EWR at 2:45 PM, in the 2 PM–3 PM bank. Departures from EWR in that hour arrive on time 76.5% of the time against 77.7% across the airport’s whole day, so the hour UA2191 leaves in is an ordinary one for EWR and explains nothing about its record either way.
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.

Because the same number has served different journeys, the statistics above describe only the route UA2191 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.
63 min late
against a median of 5 min early
UA2191 has an average that understates its risk: a typical arrival is 5 min early, but the worst tenth are 68 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. UA2191 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 651 records of UA2191 operating EWR → LAX, 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.
