These figures cover 697 flights between September 2025 and August 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.

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 flights88.8%
- 11am–2pm—
- 2pm–5pm13 flights—
- 5pm–8pm328 flights82.7%
- 8pm–5am—
Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.
The early departures do better, though not dramatically: 88.8% on time for the 8am–11am window against 82.7% 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

The worst days
Worst days for SkyWest on LAX to SAT
The latest arrival of the period was on 6 May 2026, 6 hours 43 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On four of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 May 2026 | 6 hours 43 minutes | Late-arriving aircraft |
| 18 February 2026 | 5 hours 8 minutes | Carrier |
| 29 November 2025 | 3 hours 11 minutes | Carrier |

Delay causes
Why SkyWest runs late on this route
Carrier accounts for 55% of the 6,633 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Carrier
- 31%Late-arriving aircraft
- 12%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 55%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,621 of the 6,633 delay minutes reported here. The split is drawn from 6,633 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 88.8% on time here.
Cancellations are rare at 0.29%, below the national 1.89% 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
5.6% of arrivals land an hour or more late, close to the national 8.3%, so 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.
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 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. 693 completed flights over 12 months sit behind that.
