Departure window

The best time of day to leave OGG in September

Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 1,956 flights.

5am–8am167 flights97.6%
8am–11am266 flights93.2%
11am–2pm690 flights88.7%
2pm–5pm291 flights89.0%
5pm–8pm232 flights90.9%
8pm–5am310 flights93.2%

Scale runs 80% to 100%.

The weak window here is the middle of the day, not the evening: 11am–2pm runs 88.7% on time against 97.6% for 5am–8am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 11am–2pm window is the busiest, with 690 flights scheduled in it.

Across the week, Wednesday is the strongest day at 94.2% on time and Thursday the weakest at 87.3%, a spread of 7 points.

Carrier by carrier

Which airlines ran best at OGG in September

The choice of carrier is not cosmetic here. Southwest Airlines arrives on time 97.4% of the time; Hawaiian Airlines manages 89.9%. Sample sizes sit next to every figure, because a two-point gap across 1,063 flights means less than a ten-point one.

Southwest leads Hawaiian by 8 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Delay causes

What held OGG up in September

Late-arriving aircraft accounts for 53% of the 7,919 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
53%
Carrier
37%
National Airspace System
8%
Extreme weather
2%

53% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,919 reported delay minutes here, that single category outweighs weather by 26 to one. The split is drawn from 7,919 reported delay minutes.

Cancellations are rare at 0.10%, below the national 0.51% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Badly late arrivals are rare here: only 1.9% land an hour or more behind schedule, against 5.4% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
