SkyWest on PHX to FAT lands a B+, about a point worse than the national rate of 77.3%. About one flight in four arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 535 flights, with a median arrival 7 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate SkyWest on PHX to FAT from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

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.

- 8am–11am5 flights—
- 11am–2pm—
- 2pm–5pm132 flights80.9%
- 5pm–8pm309 flights74.3%

Scale runs 45% to 95%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 52.9% on time, against 89.1% 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 5pm–8pm window is the busiest, with 309 flights scheduled in it.
Across the year
SkyWest on PHX to FAT through the year
February is the weak month at 56.4% on time, against 88.9% in May. 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 92.4% on time and Friday the weakest at 63.3%, a spread of 29 points.

The worst days
Worst days for SkyWest on PHX to FAT
The latest arrival of the period was on 5 February 2026, 13 hours 12 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 5 February 2026 | 13 hours 12 minutes | Carrier |
| 13 February 2026 | 11 hours 9 minutes | Carrier |
| 26 September 2025 | 5 hours 28 minutes | Late-arriving aircraft |

Delay causes
Why SkyWest runs late on this route
Carrier accounts for 58% of the 9,713 delay minutes carriers reported here, and the remaining four split what is left.
- 58%Carrier
- 32%Late-arriving aircraft
- 5%National Airspace System
- 5%Extreme weather
The largest share of delay minutes, 58%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,678 of the 9,713 delay minutes reported here. The split is drawn from 9,713 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 89.1% on time here.
Cancellations are rare at 0.19%, 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
9.0% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
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 83.6% on time across 535 flights, 7 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 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 PHX to FAT
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 76.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 532 completed flights over 12 months sit behind that.
