Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with SkyWest Airlines.
SkyWest on FAT to SAN lands a B, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by roughly 55 minutes on average. That is a workable record, not a spotless one. That rests on 1,235 flights, with a median arrival 2 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate SkyWest on FAT to SAN from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on FAT to SAN, 1,747 flights
These figures cover 1,235 flights between July 2025 and June 2026. The median arrival is 2 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 FAT to SAN
SkyWest flew 1,235 of the 1,747 flights on FAT to SAN, most of the route. Its 76.7% on time is about level with the route as a whole at 76.2%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from SkyWest at 76.7% to Southwest at 75.0%.
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 matters more here than the choice of carrier. The gap between the best and worst window is 36 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am359 flights91.9%
- 8am–11am331 flights74.8%
- 11am–2pm94 flights78.7%
- 2pm–5pm230 flights68.7%
- 5pm–8pm159 flights55.6%
- 8pm–5am62 flights79.3%
Scale runs 45% to 95%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 55.6% on time, against 91.9% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5am–8am window is the busiest, with 359 flights scheduled in it.
Across the year
SkyWest on FAT to SAN through the year
Delays peak in November, when the on-time rate falls to 66.7%. January is the strongest month at 85.0%. Moving a flexible trip across that boundary buys 18 points. July was the busiest month here, with 123 flights.
Across the week, Wednesday is the strongest day at 83.2% on time and Friday the weakest at 69.8%. 13 points is a smaller lever than departure hour, but it is free.
Delay causes
Why SkyWest runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 15,000 reported delay minutes.
- 36%Late-arriving aircraft
- 32%Carrier
- 24%National Airspace System
- 8%Extreme weather
36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 15,000 reported delay minutes here, that single category outweighs weather by 5 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 14,993 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 91.9% on time here.
Cancellations sit at 1.62% against a national 1.81%, which is ordinary. Diversions add another 0.73%.
Connections and stage length
What a delay here costs
6.9% 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 roughly 55 minutes, which a normal layover absorbs.
At 314 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 78.3% on time across 1,235 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.
The sample behind these figures is 1,235 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
What to do with this
Booking SkyWest on FAT to SAN
Put together: the calendar is the biggest lever here, not the carrier or the hour. January runs 85.0% on time and November 66.7%, a swing of 18 points. If the dates move at all, move them out of November before you think about anything else. 1,206 completed flights over 12 months sit behind that.
