Alaska Airlines at Los Angeles lands a B+, 4 points better than the national rate of 77.6%. Roughly one flight in five arrive 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 9,294 flights, of which SkyWest Airlines flew 40,551 at 85.5% on time.
Measured against the airport rather than the country, Alaska Airlines runs about a point ahead of the 80.4% weighted average across all carriers at LAX. That is the comparison worth making: every operator here works the same runways, the same airspace and the same weather.

#3
Of 10 carriers clearing the floor at LAX
These figures cover 9,294 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.
Against the competition
Every carrier at LAX, ranked
The choice of carrier is not cosmetic here. SkyWest Airlines arrives on time 85.5% of the time; Hawaiian Airlines manages 71.1%. Sample sizes sit next to every figure, because a two-point gap across 987 flights means less than a ten-point one.

| Hawaiian Airlines | 987 | 71.1% | 74 min | 0.91% | C+ |
The spread between SkyWest and Hawaiian is 14 points, wide enough that it should decide the booking. On a hundred trips that is 14 more arrivals inside the on-time window.
Route by route
Where Alaska Airlines flies from LAX
Alaska Airlines operates 14 routes out of LAX with enough volume to report. Route records inside one carrier at one airport still spread widely, because a short shuttle and a transcontinental have very different exposure to a late inbound.

Departure window
Best time of day for this operation
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 16 points, against 14 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1,423 flights90.6%
- 8am–11am2,180 flights74.6%
- 11am–2pm1,164 flights77.2%
- 2pm–5pm1,319 flights85.0%
- 5pm–8pm1,795 flights82.5%
- 8pm–5am1,413 flights84.1%
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 90.6% of the time, against 74.6% for the morning window. That is 16 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 2,180 flights scheduled in it.
Across the year
Seasonal pattern
June is the worst month at 74.9% on time, 18 points below September, the best at 93.1%. 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. June was the busiest month here, with 1,040 flights.

34% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 31,000 minutes out of 92,000, against a national NAS share of 21%. The split is drawn from 92,127 reported delay minutes.
Cancellations sit at 0.90% against a national 1.81%, which is ordinary. Diversions add another 0.16%.
Badly late arrivals are rare here: only 4.8% 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.
The sample behind these figures is 9,294 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.
Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 93.1% on time and June 74.9%, a swing of 18 points. If the dates move at all, move them out of June before you think about anything else. 9,195 completed flights over 12 months sit behind that.
Common questions
Alaska Airlines at LAX
How often is Alaska Airlines at LAX delayed?
Roughly 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 18.2% of the 9,294 flights in this analysis, against 22.4% nationally. Delayed flights are late by about an hour on average.
Which airline is most reliable on Alaska Airlines at LAX?
SkyWest Airlines leads at 85.5% on time across 40,551 flights. Hawaiian Airlines is at the other end on 71.1%, a gap of 14 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 Alaska Airlines at LAX?
The 5am–8am departure window is the strongest at 90.6% on time. The 8am–11am window is the weakest at 74.6%, 16 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 June delays on Alaska Airlines at LAX?
June is the weakest month at 74.9% on time, compared with 93.1% in September. Across the year that is 18 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
