These figures cover 2,178 flights between September 2025 and August 2026. The median arrival is 4 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
Which airline is most reliable on HNL to LAS
The choice of carrier is not cosmetic here. Southwest Airlines arrives on time 92.4% of the time; Hawaiian Airlines manages 70.2%. Sample sizes sit next to every figure, because a two-point gap across 468 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Southwest Airlines | 901 | 92.4% | 34 min | 0.11% | A+ |
| Alaska Airlines | 809 | 73.9% | 55 min | 0.74% | C+ |
| Hawaiian Airlines | 468 | 70.2% | 65 min | 0.21% | C+ |
The spread between Southwest and Hawaiian is 22 points, wide enough that it should decide the booking. On a hundred trips that is 22 more arrivals inside the on-time window.

Best ways to make this trip
The most reliable ways to fly Honolulu to Las Vegas
Every airline on this route, ranked by how often a scheduled flight actually operated and arrived on time, with its best departure time and most punctual flight number. No nearby airport pair beat these.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. HNL → LASHonolulu to Las Vegas | Southwest Airlines | 92.3% | 92.4% | 0.11% | 8pm–5am, Wed | — |
| 2. HNL → LASHonolulu to Las Vegas | Alaska Airlines | 73.4% | 73.9% | 0.74% | 8am–11am, Wed | — |
| 3. HNL → LASHonolulu to Las Vegas | Hawaiian Airlines | 70.1% | 70.2% | 0.21% | 5am–8am, Wed | — |
Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.
Departure window
The best time of day to leave
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 19 points, against 22 points between the best and worst carrier.

The overnight block holds up unusually well at 84.8% on time across 721 flights. Red-eyes fly into empty airspace and empty gates, and they are the first rotation of the aircraft's day rather than the last. The 8pm–5am window is the busiest, with 721 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 20 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
Delays peak in March, when the on-time rate falls to 69.3%. June is the strongest month at 89.4%. Moving a flexible trip across that boundary buys 20 points. May was the busiest month here, with 206 flights.
Across the week, Wednesday is the strongest day at 89.6% on time and Friday the weakest at 75.3%, a spread of 14 points.
Delay causes
Why this route gets delayed
Carrier accounts for 69% of the 23,000 delay minutes carriers reported here, and the remaining four split what is left.
- 69%Carrier
- 22%Late-arriving aircraft
- 8%National Airspace System
- 1%Extreme weather
- 0%Security
The largest share of delay minutes, 69%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 16,000 of the 23,000 delay minutes reported here. The split is drawn from 22,920 reported delay minutes.
Cancellations are rare at 0.37%, below the national 1.89% 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.
Connections and stage length
What a delay here actually costs
5.1% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
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 77.2% on time across 2,184 flights, 4 points below 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 4 points of difference.
The sample behind these figures is 2,178 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this
Booking this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. June runs 89.4% on time and March 69.3%, a swing of 20 points. If the dates move at all, move them out of March before you think about anything else. 2,165 completed flights over 12 months sit behind that.
Common questions
HNL to LAS questions
How often is HNL to LAS delayed?
About one flight in five arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 19.2% of the 2,178 flights in this analysis, against 22.7% nationally. Delayed flights are late by about an hour on average.
Which airline is most reliable on HNL to LAS?
Southwest Airlines leads at 92.4% on time across 901 flights. Hawaiian Airlines is at the other end on 70.2%, a gap of 22 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on HNL to LAS?
The 8pm–5am departure window is the strongest at 84.8% on time. The 2pm–5pm window is the weakest at 66.2%, 19 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are March delays on HNL to LAS?
March is the weakest month at 69.3% on time, compared with 89.4% in June. Across the year that is 20 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
