Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Envoy Air.

Envoy on PHX to MCI lands a B+, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 113 flights. The strongest carrier on the route with a full sample, American Airlines, flew 597 at 78.0% on time.

The US average over the same twelve months is 77.6%, so there is little to separate Envoy on PHX to MCI from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on PHX to MCI, 2,472 flights

These figures cover 113 flights between July 2025 and June 2026. Beyond the headline rate, 8.1% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Carrier by carrier

Envoy against every carrier on PHX to MCI

Envoy flew 113 of the 2,472 flights on PHX to MCI, about 5% of it. Its 80.2% on time is 4 points better than the route as a whole, which runs 76.5%. Ranked by on-time rate it is number three of five carriers on the route, where the range runs from SkyWest at 90.0% to Southwest at 75.0%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The two carriers here are closely matched: 3 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.

Southwest Airlines	1,636	75.0%	50 min	0.55%	B+

No carrier stands out. American tops the table at 78.0%, 3 points 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 113 flights.

5am–8am—
8am–11am—
11am–2pm32 flights75.0%
2pm–5pm3 flights—
5pm–8pm39 flights79.5%
8pm–5am39 flights83.8%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.

The weak window here is the middle of the day, not the evening: 11am–2pm runs 75.0% on time against 83.8% for 8pm–5am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 5pm–8pm window is the busiest, with 39 flights scheduled in it.

Across the year

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 80.2% on time across 113 flights.

Split by quarter, Envoy on PHX to MCI logged 14 flights in Oct–Dec 2025, 76 flights in Jan–Mar 2026 and 23 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 80.2% annual figure is the one to use.

Delay causes

Why Envoy runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 55% of the 1,238 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.

55%

34%
National Airspace System

Security
5%

55% 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 1,238 reported delay minutes here, that single category outweighs weather by 55 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 1,238 reported delay minutes.

Cancellations are rare at 0.88%, 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

8.1% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.

The 1,044 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 is a different operation and performs like one: it runs 90.3% on time across 114 flights, 10 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 10 points of difference.

One caution: this is a thin sample. 113 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 MCI

Put together: treat all of this as provisional. 113 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 80.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 111 completed flights over 12 months sit behind that.
