These figures cover 190 flights between September 2025 and August 2026. The median arrival is 8 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 SJC to PHX

Envoy flew 190 of the 3,013 flights on SJC to PHX, about 6% of it. Its 89.4% on time is 9 points better than the route as a whole, which runs 80.9%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from Envoy at 89.4% to Southwest at 77.7%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The choice of carrier is not cosmetic here. American Airlines arrives on time 86.1% of the time; Southwest Airlines manages 77.7%. Sample sizes sit next to every figure, because a two-point gap across 1,869 flights means less than a ten-point one.

American leads Southwest by 8 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Delay causes

Why Envoy runs late on this route

Late-arriving aircraft accounts for 58% of the 1,043 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    58%
  • National Airspace System
    21%
  • Extreme weather
    14%
  • Carrier
    7%

Extreme weather accounts for 14% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.3 times the usual weather exposure. The split is drawn from 1,043 reported delay minutes.

58% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,043 reported delay minutes here, that single category outweighs weather by 4 to one.

Cancellations sit at 1.05% against a national 1.89%, which is ordinary. Diversions add another 0.00%.

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 87.3% 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 SJC to PHX

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 89.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 188 completed flights over 12 months sit behind that.
