Book the early departure. Flights leaving between 5am–8am arrive on time 86.5% of the time, against 72.9% for the afternoon window. That is 14 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 365 flights scheduled in it.
Across the year
SkyWest on FAT to PHX through the year
January is the weak month at 73.3% on time, against 93.9% in August. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. January was the busiest month here, with 62 flights.
Across the week, Tuesday is the strongest day at 91.1% on time and Monday the weakest at 76.0%, a spread of 15 points.

|---|---|---|
| 26 September 2025 | 25 hours 18 minutes | Carrier |

Delay causes
Why SkyWest runs late on this route
Carrier accounts for 81% of the 11,000 delay minutes carriers reported here, and the remaining four split what is left.
- 81%Carrier
- 9%Extreme weather
- 7%Late-arriving aircraft
- 4%National Airspace System
The largest share of delay minutes, 81%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 9,091 of the 11,000 delay minutes reported here. The split is drawn from 11,287 reported delay minutes.
Cancellations are rare at 0.56%, 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
8.9% 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 2.2 hours, which a normal layover absorbs.
At 493 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 76.3% on time across 535 flights, 7 points below 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 7 points of difference.
One caution: this is a thin sample. 535 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 FAT to PHX
Put together: treat all of this as provisional. 535 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 83.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 531 completed flights over 12 months sit behind that.
