Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Envoy Air.
Envoy on MCI to PHX 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 13 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 35 minutes. That rests on 114 flights. The strongest carrier on the route with a full sample, American Airlines, flew 597 at 82.7% on time.
Set against the rest of the country, Envoy's MCI to PHX record is 13 points better than the US average of 77.6%. That gap is worth roughly 127 fewer late arrivals for every thousand flights.

Every carrier on MCI to PHX, 2,471 flights
These figures cover 114 flights between July 2025 and June 2026. The median arrival is 14 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 MCI to PHX
Envoy flew 114 of the 2,471 flights on MCI to PHX, about 5% of it. Its 90.3% on time is 11 points better than the route as a whole, which runs 79.1%. Ranked by on-time rate it is first of five carriers on the route, where the range runs from Envoy at 90.3% to SkyWest at 75.4%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The two carriers here are closely matched: 6 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.

No carrier stands out. American tops the table at 82.7%, 6 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 matters more here than the choice of carrier. The gap between the best and worst window is 14 points, against 6 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am18 flights—
- 8am–11am66 flights93.9%
- 11am–2pm—
- 2pm–5pm—
- 5pm–8pm30 flights80.0%
- 8pm–5am—
Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 93.9% of the time, against 80.0% for the evening window. That is 14 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 66 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 90.3% on time across 114 flights.
Split by quarter, Envoy on MCI to PHX logged 13 flights in Oct–Dec 2025, 77 flights in Jan–Mar 2026 and 24 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 90.3% 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 53% of the 394 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.
- 53%Late-arriving aircraft
- 27%Carrier
- 20%National Airspace System
53% 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 394 reported delay minutes here, that single category outweighs weather by 53 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 394 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 93.9% on time here.
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
Badly late arrivals are rare here: only 1.8% 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 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 80.2% on time across 113 flights, 10 points below 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. 114 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 MCI to PHX
Put together: treat all of this as provisional. 114 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 90.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 113 completed flights over 12 months sit behind that.
