This route lands a B+, 4 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That rests on 1,476 FAT to PHX flights, of which SkyWest Airlines flew 535 at 83.6% on time.
Best time to fly FAT to PHX: a 8am–11am departure, ideally on a Wednesday. Flights in that window arrived on time 89.5% of the time and Wednesday flights 84.9%, against 81.1% for the route overall.
The US average over the same twelve months is 77.3%, so there is little to separate this route from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
Which airline is most reliable on FAT to PHX
The two carriers here are closely matched: 5 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Envoy Airthin sample | 147 | 87.7% | 140 min | 0.00% | A+ |
| SkyWest Airlines | 535 | 83.6% | 130 min | 0.56% | B+ |
| American Airlines | 794 | 78.3% | 84 min | 0.76% | B+ |
No carrier stands out. SkyWest tops the table at 83.6%, 5 points clear of the bottom, which is inside the range this kind of sample moves year to year.

Best ways to make this trip
The most reliable ways to fly Fresno to Phoenix
Every airline on this route, ranked by how often a scheduled flight actually operated and arrived on time, with its best departure time and most punctual flight number. No nearby airport pair beat these.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. FAT → PHXFresno to Phoenix | SkyWest Airlines | 83.1% | 83.6% | 0.56% | 5am–8am, Tue | OO 6275 06:00 |
| 2. FAT → PHXFresno to Phoenix | American Airlines | 77.7% | 78.3% | 0.76% | 8am–11am, Wed | — |
Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.

Across the year
When delays peak on this route
This route's year swings by 18 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
June is the worst month at 70.4% on time, 18 points below September, the best at 88.0%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. March was the busiest month here, with 149 flights.
Across the week, Wednesday is the strongest day at 84.9% on time and Monday the weakest at 76.2%, a spread of 9 points.
Delay causes
Why this route gets delayed
Carrier accounts for 48% of the 28,000 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Carrier
- 44%Late-arriving aircraft
- 5%National Airspace System
- 4%Extreme weather
- 0%Security
44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 28,000 reported delay minutes here, that single category outweighs weather by 11 to one. The split is drawn from 28,215 reported delay minutes.
The largest share of delay minutes, 48%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 13,000 of the 28,000 delay minutes reported here.
Cancellations are rare at 0.61%, 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 actually costs
8.0% 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 close to two 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 8am–11am window matters as much as it does.
The return leg runs 78.9% on time across 1,476 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 1,476 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 this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 88.0% on time and June 70.4%, a swing of 18 points. If the dates move at all, move them out of June before you think about anything else. 1,464 completed flights over 12 months sit behind that.
Common questions
FAT to PHX questions
How often is FAT to PHX delayed?
About one flight in five arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 18.9% of the 1,476 flights in this analysis, against 22.7% nationally. Delayed flights are late by close to two hours on average.
Which airline is most reliable on FAT to PHX?
SkyWest Airlines leads at 83.6% on time across 535 flights. American Airlines is at the other end on 78.3%, a gap of 5 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on FAT to PHX?
The 8am–11am departure window is the strongest at 89.5% on time. The 5pm–8pm window is the weakest at 63.2%, 26 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are June delays on FAT to PHX?
June is the weakest month at 70.4% on time, compared with 88.0% in September. Across the year that is 18 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
