Departure window
The best time of day to leave HNL in July
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 17 points, against 7 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am537 flights94.6%
- 8am–11am815 flights88.6%
- 11am–2pm1,189 flights81.8%
- 2pm–5pm985 flights77.2%
- 5pm–8pm668 flights85.3%
- 8pm–5am982 flights82.8%
Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 94.6% of the time, against 77.2% for the afternoon window. That is 17 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 1,189 flights scheduled in it.
Across the week, Tuesday is the strongest day at 86.5% on time and Thursday the weakest at 80.1%. 6 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at HNL in July
The choice of carrier is not cosmetic here. Southwest Airlines arrives on time 88.7% of the time; Hawaiian Airlines manages 81.8%. Sample sizes sit next to every figure, because a two-point gap across 2,897 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Hawaiian Airlines | 2,897 | 81.8% | 41 min | 0.55% | B+ |
| Southwest Airlines | 1,125 | 88.7% | 49 min | 2.13% | A |
| United Airlines | 503 | 88.5% | 101 min | 1.59% | A |
| Delta Air Linesthin sample | 310 | 88.7% | 71 min | 2.58% | A |
| American Airlinesthin sample | 217 | 82.6% | 199 min | 1.38% | B |
| Alaska Airlinesthin sample | 124 | 63.3% | 55 min | 3.23% | D− |
Southwest leads Hawaiian by 7 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Delay causes
What held HNL up in July
One category carries most of the weight here. Carrier accounts for 48% of the 46,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 48%Carrier
- 40%Late-arriving aircraft
- 9%Extreme weather
- 3%National Airspace System
- 0%Security
40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 46,000 reported delay minutes here, that single category outweighs weather by 4 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 45,701 reported delay minutes.
Cancellations sit at 1.22% against a national 2.45%, which is ordinary. Diversions add another 0.10%.
Badly late arrivals are rare here: only 3.2% land an hour or more behind schedule, against 12.1% 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.
