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 LAS to SNA
SkyWest flew 760 of the 4,252 flights on LAS to SNA, about 18% of it. Its 86.7% on time is 5 points better than the route as a whole, which runs 81.9%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from Spirit at 87.5% to Southwest at 78.8%. 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 87.5% of the time; Southwest Airlines manages 78.8%. Sample sizes sit next to every figure, because a two-point gap across 2,498 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Spirit Airlines | 780 | 87.5% | 71 min | 1.54% | A |
| SkyWest Airlines (this page) | 760 | 86.7% | 81 min | 0.66% | A+ |
| Frontier Airlinesthin sample | 214 | 81.7% | 61 min | 0.47% | B+ |
| Southwest Airlines | 2,498 | 78.8% | 48 min | 0.52% | B+ |
Spirit leads Southwest by 9 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 matters more here than the choice of carrier. The gap between the best and worst window is 13 points, against 9 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am35 flights97.1%
- 8am–11am330 flights86.9%
- 11am–2pm—
- 2pm–5pm251 flights86.3%
- 5pm–8pm144 flights84.5%
- 8pm–5am—
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 97.1% of the time, against 84.5% for the evening window. That is 13 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 330 flights scheduled in it.
Across the year
SkyWest on LAS to SNA through the year
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 83.0%. 11 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 67% of the 8,068 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.
- 67%Carrier
- 25%National Airspace System
- 8%Extreme weather
The largest share of delay minutes, 67%, 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 5,429 of the 8,068 delay minutes reported here. The split is drawn from 8,068 reported delay minutes.
Cancellations are rare at 0.66%, 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 4.4% 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.
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 5am–8am window matters as much as it does.
The return leg runs 85.9% 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 LAS to SNA
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 86.7% 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.
