These figures cover 817 flights between July 2025 and June 2026. The median arrival is 11 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

SkyWest against every carrier on LAX to AUS

SkyWest flew 817 of the 4,076 flights on LAX to AUS, about 20% of it. Its 85.6% on time is 7 points better than the route as a whole, which runs 78.3%. Ranked by on-time rate it is number two of six carriers on the route, where the range runs from United at 87.5% to American at 68.7%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The choice of carrier is not cosmetic here. United Airlines arrives on time 87.5% of the time; American Airlines manages 68.7%. Sample sizes sit next to every figure, because a two-point gap across 480 flights means less than a ten-point one.

Departure window

When SkyWest runs best on this route

Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 817 flights.

  • 5am–8am
  • 8am–11am384 flights86.4%
  • 11am–2pm35 flights82.9%
  • 2pm–5pm151 flights84.6%
  • 5pm–8pm247 flights85.4%
  • 8pm–5am

Scale runs 75% to 90%. Rows with fewer than 30 flights show a dash.

The time of day barely matters here. The 8am–11am window tops the set at 86.4% and 11am–2pm sits at 82.9%, 4 points apart across 817 flights. Pick the departure that suits the trip: whatever is going wrong here is not accumulating over the course of the day. The 8am–11am window is the busiest, with 384 flights scheduled in it.

Darker means more delays. Figures are on-time percentages.July best, November worst

Delays peak in November, when the on-time rate falls to 74.0%. July is the strongest month at 94.1%. Moving a flexible trip across that boundary buys 20 points. June was the busiest month here, with 117 flights.

Across the week, Friday is the strongest day at 87.8% on time and Sunday the weakest at 83.1%. 5 points is a smaller lever than departure hour, but it is free.

Delay causes

Why SkyWest runs late on this route

One category carries most of the weight here. Carrier accounts for 44% of the 6,827 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.

  • Carrier
    44%
  • Late-arriving aircraft
    26%
  • National Airspace System
    15%
  • Extreme weather
    15%

Extreme weather accounts for 15% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.3 times the usual weather exposure. The split is drawn from 6,827 reported delay minutes.

The largest share of delay minutes, 44%, 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 3,033 of the 6,827 delay minutes reported here.

Cancellations are rare at 0.49%, below the national 1.81% 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 costs

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 1,242 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The return leg runs 88.0% on time across 817 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.

One caution: this is a thin sample. 817 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.

What to do with this

Booking SkyWest on LAX to AUS

Put together: treat all of this as provisional. 817 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 85.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 811 completed flights over 12 months sit behind that.
