Route reliability record

LAX→HNL

Los Angeles to Honolulu

Flights: 5,427
Period: June 2025 to May 2026
Distance: 2,556 mi
Carriers: 6

This route lands a B+, about a point worse than the national rate of 77.4%. About one flight in four 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 5,427 flights, of which United Airlines flew 1,259 at 85.3% on time.

United Airlines is the most reliable of the six carriers covered here at 85.3% on time across 1,259 flights.

These figures cover 5,427 flights between June 2025 and May 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 LAX to HNL

The choice of carrier is not cosmetic here. United Airlines arrives on time 85.3% of the time; Hawaiian Airlines manages 61.7%. Sample sizes sit next to every figure, because a two-point gap across 736 flights means less than a ten-point one.

On-time performance by carrier on LAX to HNL
Airline	Flights	On time	Avg delay	Cancelled	Grade
United Airlines	1,259	85.3%	102 min	0.40%	A+
Southwest Airlines	513	84.8%	51 min	0.19%	B+
Delta Air Lines	1,095	80.4%	71 min	0.37%	B+
American Airlines	1,179	75.5%	54 min	0.17%	B+
Alaska Airlines	645	66.0%	73 min	1.09%	C
Hawaiian Airlines	736	61.7%	77 min	1.09%	D

The spread between United and Hawaiian is 24 points, wide enough that it should decide the booking. On a hundred trips that is 24 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 47 points, against 24 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am614 flights89.9%
8am–11am1,778 flights75.5%
11am–2pm608 flights80.5%
2pm–5pm589 flights76.7%
5pm–8pm1,681 flights74.8%
8pm–5am157 flights42.7%

Scale runs 35% to 95%. Rows with fewer than 30 flights show a dash.

The 8pm–5am window is where this operation falls apart: 42.7% on time, against 89.9% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in.

Across the year

When delays peak on this route

This route's year swings by 21 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.November best, April worst

November is the best month on the calendar at 86.6% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back.

Across the week, Wednesday is the strongest day at 79.4% on time and Sunday the weakest at 72.8%. 7 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 56% of the 91,000 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.

35% 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 91,000 reported delay minutes here, that single category outweighs weather by 35 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 largest share of delay minutes, 56%, 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 51,000 of the 91,000 delay minutes reported here.

Cancellations are rare at 0.50%, below the national 1.80% 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

7.7% of arrivals land an hour or more late, close to the national 8.2%. 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 81.8% on time across 5,425 flights, 5 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 5 points of difference.

The sample behind these figures is 5,427 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. November runs 86.6% on time and April 65.8%, a swing of 21 points. If the dates move at all, move them out of April before you think about anything else.

Common questions

LAX to HNL questions

How often is LAX to HNL delayed?

About one flight in four arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 23.4% of the 5,427 flights in this analysis, against 22.6% nationally. Delayed flights are late by a little over an hour on average.

Which airline is most reliable on LAX to HNL?

United Airlines leads at 85.3% on time across 1,259 flights. Hawaiian Airlines is at the other end on 61.7%, a gap of 24 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 LAX to HNL?

The 5am–8am departure window is the strongest at 89.9% on time. The 8pm–5am window is the weakest at 42.7%, 47 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 April delays on LAX to HNL?

April is the weakest month at 65.8% on time, compared with 86.6% in November. Across the year that is 21 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. LAX to HNL and HNL to LAX are scored separately because they are separate operations, with different departure banks and different aircraft. Compare the return leg.
