Historical statistics for June 2026, not live status or a forecast for this year’s June. For today’s conditions at LAX, see live FAA status.

LAX in June lands a B+, 3 points better than the national rate of 74.3%. Roughly one flight in four arrives 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 16,664 flights, of which SkyWest Airlines flew 3,461 at 85.6% on time.

SkyWest Airlines is the most reliable of the eight carriers covered here at 85.6% on time across 3,461 flights.

Departure window

The best time of day to leave LAX in June

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 21 points, against 27 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am2,160 flights90.4%
  • 8am–11am4,054 flights81.8%
  • 11am–2pm2,554 flights71.8%
  • 2pm–5pm2,299 flights69.9%
  • 5pm–8pm2,497 flights71.3%
  • 8pm–5am3,100 flights75.5%

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 90.4% of the time, against 69.9% for the afternoon window. That is 21 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 4,054 flights scheduled in it.

Across the week, Tuesday is the strongest day at 82.8% on time and Thursday the weakest at 73.5%. 9 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at LAX in June

The choice of carrier is not cosmetic here. SkyWest Airlines arrives on time 85.6% of the time; Southwest Airlines manages 58.6%. Sample sizes sit next to every figure, because a two-point gap across 2,275 flights means less than a ten-point one.

Delay causes

What held LAX up in June

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 262,000 reported delay minutes.

  • Late-arriving aircraft
    40%
  • Carrier
    38%
  • National Airspace System
    21%
  • Extreme weather
    1%
  • Security
    0%

40% 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 262,000 reported delay minutes here, that single category outweighs weather by 27 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 262,321 reported delay minutes.

Cancellations are rare at 0.61%, below the national 1.65% 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.

8.0% of arrivals land an hour or more late, close to the national 9.7%. 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 last a little over an hour, which a normal layover absorbs.

What to do with this

Flying from LAX in June

For a June trip through LAX: plan on this being one of the airport's harder months. The 5am–8am departures held up best at 90.4% on time, and with 8.0% of arrivals an hour or more late, a connection here deserves more slack than the same trip in September would.
