Why AA143 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 AA143 on LAX → HNL. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies AA143 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, AA143 pushed back an average of 28 minutes late; when it came in on time or early, an average of 3 minutes late.
Each departure is matched to the flight the same aircraft flew into LAX just before it, using the tail number in the DOT file, 1,005 of 1,074 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 |
|---|---|---|---|
| AA143 | 13% | 46% | 11% |
| Network, same turn | 23% | 40% | 9% |
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 AA143’s aircraft landed 15 or more minutes late is lower than the network’s and, once the aircraft was late, how often AA143 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves LAX late, does that still matter by the time it reaches HNL?
AA143 pushes back an average of 8.8 minutes late and reaches the gate at HNL an average of 0.2 minutes early. The 9.0 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 16.8 minutes on the taxiways at LAX is about what any departure from the airport in that hour spends.
On arrival at HNL, AA143 spends 7.0 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 1.3 minutes shorter than a typical HNL arrival (8.3 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 HNL. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 26,191 departures from LAX scheduled in the clock hour AA143 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at HNL (186,355 flights), not just AA143’s own. More on taxi time.

The hour it leaves LAX
Part of any flight’s record belongs to the clock rather than to the flight. AA143 has one departure time, so this is what that time is worth.
On-time arrival rate. 26,191 departures from LAX are scheduled in the 3 PM–4 PM hour over the period, against 595,153 across the whole day.
AA143 is scheduled out of LAX at 3:17 PM, in the 3 PM–4 PM bank. Departures from LAX in that hour arrive on time 78.2% of the time against 81.4% across the airport’s whole day — the slot alone is worth 3.2 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from LAX 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 AA143 run worse on particular days?
Wednesday is historically the most reliable day and Sunday the least, a gap of 11.1 percentage points.

Other routes AA143 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.
| Route | Operated | Flights | On time |
|---|---|---|---|
| DFW→PHL Dallas–Fort Worth to Philadelphia | August 15, 2023 | 1 | — |
Because the same number has served different journeys, the statistics above describe only the route AA143 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. AA143 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 1,074 records of AA143 operating LAX → HNL, 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.
