Every carrier on FAT to SAN, 1,818 flights
These figures cover 1,191 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

When SkyWest runs best on this route

Share of 1,161 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 206 departures that left 15 minutes late or more, only 15 made it up before arrival. In the other direction, 119 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at SAN.
The worst days
Worst days for SkyWest on FAT to SAN
The latest arrival of the period was on 10 May 2026, 5 hours 42 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 10 May 2026 | 5 hours 42 minutes | Carrier |
| 8 March 2026 | 4 hours 24 minutes | Carrier |
| 1 January 2026 | 4 hours 13 minutes | Late-arriving aircraft |
| 10 May 2026 | 4 hours 3 minutes | Carrier |

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 16,000 reported delay minutes.
- 36%Carrier
- 30%National Airspace System
- 27%Late-arriving aircraft
- 7%Extreme weather
The largest share of delay minutes, 36%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,905 of the 16,000 delay minutes reported here. The split is drawn from 16,340 reported delay minutes.
Cancellations sit at 1.93% against a national 1.89%, which is ordinary. Diversions add another 0.59%.
Connections and stage length
What a delay here costs
7.4% 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 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 is a different operation and performs like one: it runs 77.1% on time across 1,191 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.
The sample behind these figures is 1,191 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 August 59.0%, a swing of 26 points. If the dates move at all, move them out of August before you think about anything else. 1,161 completed flights over 12 months sit behind that.
