screening or terminal security incidents
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically

Data and methodology
Calculated by FlyerIntel from 847 records of HA12 operating HNL → SFO, 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.
