Every carrier on SNA to LAS, 4,252 flights

These figures cover 760 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 SNA to LAS

SkyWest flew 760 of the 4,252 flights on SNA to LAS, about 18% of it. Its 85.9% on time is 3 points better than the route as a whole, which runs 83.0%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from Spirit at 88.5% to Frontier at 75.0%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The choice of carrier is not cosmetic here. Spirit Airlines arrives on time 88.5% of the time; Southwest Airlines manages 81.0%. Sample sizes sit next to every figure, because a two-point gap across 2,498 flights means less than a ten-point one.

Spirit Airlines	781	88.5%	84 min	1.66%	A

Spirit leads Southwest by 8 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

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 760 flights.

5am–8am—
8am–11am226 flights85.0%
11am–2pm139 flights87.1%
2pm–5pm4 flights—
5pm–8pm287 flights86.6%
8pm–5am104 flights85.3%

Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.

The time of day barely matters here. The 11am–2pm window tops the set at 87.1% and 8am–11am sits at 85.0%, 2 points apart across 760 flights. Pick the departure that suits the trip: whatever is going wrong here is not accumulating over the course of the day. The 5pm–8pm window is the busiest, with 287 flights scheduled in it.

Across the year

SkyWest on SNA to LAS through the year

Darker means more delays. Figures are on-time percentages.March best, September worst

Delays peak in September, when the on-time rate falls to 76.3%. March is the strongest month at 93.5%. Moving a flexible trip across that boundary buys 17 points. July was the busiest month here, with 88 flights.

Across the week, Wednesday is the strongest day at 93.5% on time and Friday the weakest at 76.6%. 17 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 70% of the 10,000 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.

The largest share of delay minutes, 70%, 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 7,183 of the 10,000 delay minutes reported here. The split is drawn from 10,332 reported delay minutes.

Cancellations are rare at 0.79%, 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

5.7% 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 last an hour and a half, which a normal layover absorbs.

At 226 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 11am–2pm window matters as much as it does.

The return leg runs 86.7% on time across 760 flights, within about a point 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. 760 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 SNA to LAS

Put together: treat all of this as provisional. 760 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 85.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 754 completed flights over 12 months sit behind that.
