BGRADE

JetBlue Airways at Los Angeles sits in the middle of the pack with a B. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.3%. The late ones land a little over an hour behind schedule. That rests on 7,733 flights, of which SkyWest Airlines flew 40,778 at 84.9% on time.

Measured against the airport rather than the country, JetBlue Airways runs 4 points behind the 79.5% 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.

Against the competition

Every carrier at LAX, ranked

The choice of carrier is not cosmetic here. SkyWest Airlines arrives on time 84.9% of the time; Southwest Airlines manages 72.3%. Sample sizes sit next to every figure, because a two-point gap across 25,511 flights means less than a ten-point one.

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 13 points between the best and worst carrier.

  • 5am–8am1,021 flights87.2%
  • 8am–11am1,593 flights76.6%
  • 11am–2pm1,605 flights69.0%
  • 2pm–5pm1,338 flights73.6%
  • 5pm–8pm3 flights—
  • 8pm–5am2,173 flights75.8%

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 69.0% on time against 87.2% 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 2,173 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.

45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 124,000 reported delay minutes here, that single category outweighs weather by 45 to one. The split is drawn from 124,085 reported delay minutes.

Cancellations run at 2.66%, against 1.89% nationally. That is about one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

8.8% 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 a little over an hour, which a normal layover absorbs.

The sample behind these figures is 7,733 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. 7,496 completed flights over 12 months sit behind that.

Common questions

JetBlue Airways at LAX

How often is JetBlue Airways at LAX delayed?

About one flight in four arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 24.3% of the 7,733 flights in this analysis, against 22.7% 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 84.9% on time across 40,778 flights. Southwest Airlines is at the other end on 72.3%, a gap of 13 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 87.2% on time. The 11am–2pm window is the weakest at 69.0%, 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.
