Why UA1157 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 UA1157 on HNL → LAX. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies UA1157 comes in late, and what that does to the departure.
The aircraft flying UA1157 came in 15 or more minutes late on 19% 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 HNL just before it, using the tail number in the DOT file, 156 of 858 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 |
|---|---|
| UA1157 | 19% |
| 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 UA1157’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 HNL late, does that still matter by the time it reaches LAX?
UA1157 pushes back an average of 10.9 minutes late and reaches the gate at LAX an average of 5.4 minutes late. The 5.6 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. It spends 20.9 minutes on the taxiways at HNL, 2.4 minutes longer than a typical HNL departure in the same hour.
On arrival at LAX, UA1157 spends 14.3 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 3.6 minutes longer than a typical LAX 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 LAX. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 16,923 departures from HNL scheduled in the clock hour UA1157 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 UA1157’s own. More on taxi time.

The hour it leaves HNL
Part of any flight’s record belongs to the clock rather than to the flight. UA1157 has one departure time, so this is what that time is worth.
On-time arrival rate. 16,923 departures from HNL are scheduled in the 1 PM–2 PM hour over the period, against 186,300 across the whole day.
UA1157 is scheduled out of HNL at 1:00 PM, in the 1 PM–2 PM bank. Departures from HNL in that hour arrive on time 77.9% of the time against 85.3% across the airport’s whole day — the slot alone is worth 7.4 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from HNL 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 UA1157 run worse on particular days?
Thursday is historically the most reliable day and Saturday the least, a gap of 8.6 percentage points.

Other routes UA1157 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.

Because the same number has served different journeys, the statistics above describe only the route UA1157 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. UA1157 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 859 records of UA1157 operating HNL → 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.
