These figures cover 190 flights between September 2025 and August 2026. The median arrival is 11 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

Delay causes

Why Envoy runs late on this route

Late-arriving aircraft accounts for 63% of the 1,086 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
63%
Carrier
31%
National Airspace System
6%

63% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,086 reported delay minutes here, that single category outweighs weather by 63 to one. The split is drawn from 1,086 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 94.0% on time here.

Cancellations are rare at 0.53%, 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

Badly late arrivals are rare here: only 3.2% land an hour or more behind schedule, against 8.3% 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.

The return leg runs 89.4% on time across 190 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.

One caution: this is a thin sample. 190 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. 190 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 87.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 189 completed flights over 12 months sit behind that.
