Other routes AS1108 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 |
|---|---|---|---|
| SEA→SAN Seattle to San Diego | 2023-07-02 – 2025-10-25 | 757 | 79.8% |
Because the same number has served different journeys, the statistics above describe only the route AS1108 currently operates. Blending them would produce an average of two different flights.
When it goes wrong

Percentiles over 162 operations. Cancelled and diverted flights have no arrival time and are counted separately rather than as very late arrivals.
Why AS1108 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding, fuelling — 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
Share of the delay minutes US DOT attributed to each cause for AS1108 on HNL → KOA. A single late flight can carry more than one cause, and only delays of fifteen minutes or more are attributed at all.
Other departures on HNL → KOA
Same airports, same journey — and not the same odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|
| HA198 | Hawaiian Airlines | 96.0% | 2 min early | 654 |
| HA278 | Hawaiian Airlines | 83.4% | 3 min late | 720 |
| HA368 | Hawaiian Airlines | 78.1% | 3 min late | 687 |
Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 162 records of AS1108 operating HNL → KOA, 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.
