Envoy on PHX to SJC earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 45 minutes. That rests on 220 flights. The strongest carrier on the route with a full sample, Southwest Airlines, flew 1,866 at 77.7% on time.

Set against the rest of the country, Envoy's PHX to SJC record is 10 points better than the US average of 77.6%. That gap is worth roughly 96 fewer late arrivals for every thousand flights.

Every carrier on PHX to SJC, 3,016 flights

These figures cover 220 flights between July 2025 and June 2026. The median arrival is 9 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

Envoy against every carrier on PHX to SJC

Envoy flew 220 of the 3,016 flights on PHX to SJC, about 7% of it. Its 87.2% on time is 8 points better than the route as a whole, which runs 79.0%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from Envoy at 87.2% to American at 76.5%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The two carriers here are closely matched: about a point 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.

No carrier stands out. Southwest tops the table at 77.7%, about a point clear of the bottom, which is inside the range this kind of sample moves year to year.

Departure window

When Envoy runs best on this route

Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 220 flights.

The 8am–11am window is the strongest at 93.7% on time. The full set of windows spans 3 points.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 87.2% on time across 220 flights.

Quarter by quarter Envoy on PHX to SJC held fairly steady: 92.1% in Jul–Sep 2025, 82.9% in Oct–Dec 2025 and 89.7% in Jan–Mar 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Across the week, Wednesday is the strongest day at 90.6% on time and Tuesday the weakest at 86.1%. 5 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Envoy runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 62% of the 1,197 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

62%

30%
National Airspace System

62% 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 1,197 reported delay minutes here, that single category outweighs weather by 62 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 1,197 reported delay minutes.

The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 93.7% on time here.

Cancellations are rare at 0.45%, below the national 1.81% 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

Badly late arrivals are rare here: only 2.7% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

The 621 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The return leg runs 89.9% on time across 220 flights, within 3 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.

One caution: this is a thin sample. 220 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 Envoy on PHX to SJC

Put together: treat all of this as provisional. 220 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 87.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 219 completed flights over 12 months sit behind that.
