Route reliability record

HNL→LAX

Honolulu to Los Angeles

Flights: 5,458
Period: July 2025 to June 2026
Distance: 2,556 mi
Carriers: 6

This route lands a B+, 4 points better than the national rate of 77.6%. About one flight in five arrive 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 5,458 flights, of which Southwest Airlines flew 517 at 89.7% on time.

Southwest Airlines is the most reliable of the six carriers covered here at 89.7% on time across 517 flights.

89.7% on time across 517 flights

These figures cover 5,458 flights between July 2025 and June 2026. The median arrival is 7 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 LAX

The choice of carrier is not cosmetic here. Southwest Airlines arrives on time 89.7% of the time; Hawaiian Airlines manages 63.0%. Sample sizes sit next to every figure, because a two-point gap across 619 flights means less than a ten-point one.

On-time performance by carrier on HNL to LAX
Airline	Flights	On time	Avg delay	Cancelled	Grade
Southwest Airlines	517	89.7%	39 min	0.77%	A+
Delta Air Lines	1,095	88.3%	72 min	0.64%	A+
United Airlines	1,268	87.4%	94 min	0.47%	A+
American Airlines	1,183	84.6%	137 min	0.08%	B+
Alaska Airlines	776	64.1%	48 min	0.39%	D+
Hawaiian Airlines	619	63.0%	65 min	1.29%	D

The spread between Southwest and Hawaiian is 27 points, wide enough that it should decide the booking. On a hundred trips that is 27 more arrivals inside the on-time window.

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 14 points, against 27 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am697 flights88.6%
8am–11am494 flights80.9%
11am–2pm1,300 flights75.2%
2pm–5pm867 flights74.6%
5pm–8pm—
8pm–5am2,100 flights85.1%

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 88.6% of the time, against 74.6% for the afternoon window. That is 14 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8pm–5am window is the busiest, with 2,100 flights scheduled in it.

Across the year

When delays peak on this route

This route's year swings by 23 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.

Darker means more delays. Figures are on-time percentages.September best, March worst

September is the best month on the calendar at 90.4% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. June was the busiest month here, with 562 flights.

Across the week, Wednesday is the strongest day at 84.2% on time and Sunday the weakest at 77.8%. 6 points is a smaller lever than departure hour, but it is free.

Delay causes

Why this route gets delayed

One category carries most of the weight here. Carrier accounts for 63% of the 79,000 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.

The largest share of delay minutes, 63%, 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 50,000 of the 79,000 delay minutes reported here. The split is drawn from 79,140 reported delay minutes.

Cancellations are rare at 0.53%, below the national 1.81% 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

5.2% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route are the a little over an hour kind, which a normal layover absorbs.

At 2,556 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 76.9% on time across 5,459 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 5,458 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. September runs 90.4% on time and March 67.2%, a swing of 23 points. If the dates move at all, move them out of March before you think about anything else. 5,425 completed flights over 12 months sit behind that.

Common questions

HNL to LAX questions

How often is HNL to LAX delayed?

About one flight in five arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 18.9% of the 5,458 flights in this analysis, against 22.4% nationally. Delayed flights are late by a little over an hour on average.

Which airline is most reliable on HNL to LAX?

Southwest Airlines leads at 89.7% on time across 517 flights. Hawaiian Airlines is at the other end on 63.0%, a gap of 27 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 LAX?

The 5am–8am departure window is the strongest at 88.6% on time. The 2pm–5pm window is the weakest at 74.6%, 14 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 LAX?

March is the weakest month at 67.2% on time, compared with 90.4% in September. Across the year that is 23 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.

Where to go next

Direction matters. HNL to LAX and LAX to HNL are scored separately because they are separate operations, with different departure banks and different aircraft. Compare the return leg.
