Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Southwest Airlines.
Southwest on LAS to HNL earns an A+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 35 minutes. That rests on 902 flights. The strongest carrier on the route with a full sample, Alaska Airlines, flew 636 at 73.1% on time.
Set against the rest of the country, Southwest's LAS to HNL record is 8 points better than the US average of 77.6%. That gap is worth roughly 80 fewer late arrivals for every thousand flights.

Every carrier on LAS to HNL, 2,208 flights
These figures cover 902 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 LAS to HNL
Southwest flew 902 of the 2,208 flights on LAS to HNL, about 41% of it. Its 85.6% on time is 9 points better than the route as a whole, which runs 76.9%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Southwest at 85.6% to Hawaiian at 69.0%.
The two carriers here are closely matched: 4 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Southwest Airlines (this page) | 902 | 85.6% | 37 min | 0.00% | A+ |
| Alaska Airlines | 636 | 73.1% | 64 min | 1.10% | C |
| Hawaiian Airlines | 670 | 69.0% | 85 min | 0.15% | C+ |
No carrier stands out. Alaska tops the table at 73.1%, 4 points clear of the bottom, which is inside the range this kind of sample moves year to year.
Departure window
When Southwest runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 12 points, against 4 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1 flights—
- 8am–11am837 flights86.4%
- 11am–2pm64 flights74.6%
- 2pm–5pm—
- 5pm–8pm—
- 8pm–5am—
Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.
The weak window here is the middle of the day, not the evening: 11am–2pm runs 74.6% on time against 86.4% for 8am–11am. 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 8am–11am window is the busiest, with 837 flights scheduled in it.
Across the year
Southwest on LAS to HNL through the year
Delays peak in April, when the on-time rate falls to 72.2%. August is the strongest month at 93.2%. Moving a flexible trip across that boundary buys 21 points. May was the busiest month here, with 93 flights.
Across the week, Saturday is the strongest day at 88.9% on time and Sunday the weakest at 81.2%. 8 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. Carrier accounts for 57% of the 4,439 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.
- 57%Carrier
- 28%National Airspace System
- 12%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 57%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,545 of the 4,439 delay minutes reported here. The split is drawn from 4,439 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 1.5% 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 2,762 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
The return leg is a different operation and performs like one: it runs 92.6% on time across 902 flights, 7 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 7 points of difference.
One caution: this is a thin sample. 902 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 LAS to HNL
Put together: treat all of this as provisional. 902 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 85.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 879 completed flights over 12 months sit behind that.
