BGRADE

JetBlue Airways at Los Angeles lands a B, level with the national rate of 77.6%. Roughly 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 7,698 flights, of which SkyWest Airlines flew 40,551 at 85.5% on time.

Measured against the airport rather than the country, JetBlue Airways runs 3 points behind 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.

#6

Of 10 carriers clearing the floor at LAX

These figures cover 7,698 flights between July 2025 and June 2026. Beyond the headline rate, 8.9% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

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.

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 JetBlue Airways flies from LAX

JetBlue Airways operates 6 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 18 points, against 14 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am960 flights88.2%
  • 8am–11am1,663 flights77.4%
  • 11am–2pm1,679 flights70.6%
  • 2pm–5pm1,211 flights74.3%
  • 5pm–8pm1 flights
  • 8pm–5am2,184 flights78.1%

Scale runs 60% to 95%. 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 70.6% on time against 88.2% for 5am–8am. 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 8pm–5am window is the busiest, with 2,184 flights scheduled in it.

May is the best month on the calendar at 85.3% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. December was the busiest month here, with 756 flights.

43% 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 122,000 reported delay minutes here, that single category outweighs weather by 43 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 split is drawn from 122,384 reported delay minutes.

Cancellations sit at 1.82% against a national 1.81%, which is ordinary. Diversions add another 0.38%.

8.9% 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.

The sample behind these figures is 7,698 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. May runs 85.3% on time and March 63.8%, a swing of 22 points. If the dates move at all, move them out of March before you think about anything else. 7,529 completed flights over 12 months sit behind that.

Common questions

JetBlue Airways at LAX

How often is JetBlue Airways at LAX delayed?

Roughly 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 23.0% of the 7,698 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 JetBlue Airways 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 JetBlue Airways at LAX?

The 5am–8am departure window is the strongest at 88.2% on time. The 11am–2pm window is the weakest at 70.6%, 18 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 JetBlue Airways at LAX?

March is the weakest month at 63.8% on time, compared with 85.3% in May. Across the year that is 22 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
