These figures cover 697 flights between July 2025 and June 2026. The median arrival is 7 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 SAT
SkyWest flew 697 of the 1,881 flights on LAX to SAT, about 37% of it. Its 86.0% on time is 4 points better than the route as a whole, which runs 82.1%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from SkyWest at 86.0% to Southwest at 68.5%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

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 697 flights.
- 5am–8am—
- 8am–11am356 flights88.5%
- 11am–2pm—
- 2pm–5pm13 flights—
- 5pm–8pm328 flights83.3%
- 8pm–5am—
Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.
The early departures do better, though not dramatically: 88.5% on time for the 8am–11am window against 83.3% for 5pm–8pm. Worth taking if the schedule allows, not worth an extra connection. The 8am–11am window is the busiest, with 356 flights scheduled in it.
Across the year
SkyWest on LAX to SAT through the year
October is the best month on the calendar at 94.9% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. May was the busiest month here, with 62 flights.
Across the week, Friday is the strongest day at 89.7% on time and Saturday the weakest at 79.8%. 10 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 59% of the 6,493 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.
- 59%Carrier
- 31%Late-arriving aircraft
- 9%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 59%, 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 3,807 of the 6,493 delay minutes reported here. The split is drawn from 6,493 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 88.5% on time here.
Cancellations are rare at 0.29%, 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
5.9% 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 about an hour, which a normal layover absorbs.
The 1,211 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 is a different operation and performs like one: it runs 90.3% on time across 697 flights, 4 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 4 points of difference.
One caution: this is a thin sample. 697 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 SAT
Put together: treat all of this as provisional. 697 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 86.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 693 completed flights over 12 months sit behind that.
