Every carrier on LIH to OGG, 1,460 flights
These figures cover 365 flights between July 2025 and June 2026. The median arrival is 8 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.
Carrier by carrier
Southwest against every carrier on LIH to OGG
Southwest flew 365 of the 1,460 flights on LIH to OGG, about 25% of it. Its 84.3% on time is about level with the route as a whole at 83.0%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Hawaiian at 87.1% to Alaska at 78.0%.
The choice of carrier is not cosmetic here. Hawaiian Airlines arrives on time 87.1% of the time; Alaska Airlines manages 78.0%. Sample sizes sit next to every figure, because a two-point gap across 543 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Hawaiian Airlines | 552 | 87.1% | 37 min | 0.36% | A+ |
| Southwest Airlines (this page) | 365 | 84.3% | 51 min | 0.00% | B+ |
| Alaska Airlines | 543 | 78.0% | 37 min | 0.00% | B+ |
Hawaiian leads Alaska by 9 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.
Departure window
When Southwest runs best on this route
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 365 flights.
- 5am–8am—
- 8am–11am—
- 11am–2pm124 flights86.3%
- 2pm–5pm241 flights83.3%
- 5pm–8pm—
- 8pm–5am—
Scale runs 75% to 90%. Rows with fewer than 30 flights show a dash.
The 11am–2pm window is the strongest at 86.3% on time. The full set of windows spans 3 points.
Across the year
Southwest on LIH to OGG through the year
July is the worst month at 67.7% on time, 32 points below June, the best at 100.0%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. January was the busiest month here, with 31 flights.
Across the week, Tuesday is the strongest day at 90.6% on time and Sunday the weakest at 78.8%. 12 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Southwest runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 66% of the 2,903 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.
- 66%Late-arriving aircraft
- 23%Carrier
- 11%National Airspace System
66% 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 2,903 reported delay minutes here, that single category outweighs weather by 66 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 2,903 reported delay minutes.
Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 4.1% land an hour or more behind schedule, against 8.1% 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.
At 202 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 11am–2pm window matters as much as it does.
The return leg runs 82.7% on time across 365 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 365 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking Southwest on LIH to OGG
Put together: treat all of this as provisional. 365 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 84.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 364 completed flights over 12 months sit behind that.
