Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Envoy Air.
Envoy on PHX to YUM 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 55 minutes. That rests on 318 flights, with a median arrival 4 minutes early.
Set against the rest of the country, Envoy's PHX to YUM record is 10 points better than the US average of 77.6%. That gap is worth roughly 103 fewer late arrivals for every thousand flights.

Every carrier on PHX to YUM, 1,328 flights
These figures cover 318 flights between July 2025 and June 2026. The median arrival is 4 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 YUM
Envoy flew 318 of the 1,328 flights on PHX to YUM, about 24% of it. Its 87.9% on time is 3 points better than the route as a whole, which runs 84.9%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from Envoy at 87.9% to SkyWest at 84.0%.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

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 10 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am—
- 8am–11am78 flights93.0%
- 11am–2pm52 flights82.7%
- 2pm–5pm163 flights86.7%
- 5pm–8pm2 flights—
- 8pm–5am23 flights—
Scale runs 75% to 100%. 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 82.7% on time against 93.0% for 8am–11am. 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 2pm–5pm window is the busiest, with 163 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 87.9% on time across 318 flights.
Split by quarter, Envoy on PHX to YUM logged 28 flights in Jul–Sep 2025, 173 flights in Oct–Dec 2025, 93 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 87.9% annual figure is the one to use.
Across the week, Monday is the strongest day at 95.7% on time and Sunday the weakest at 80.5%. 15 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 69% of the 1,955 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.
- 69%Late-arriving aircraft
- 22%Carrier
- 9%National Airspace System
69% 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 1,955 reported delay minutes here, that single category outweighs weather by 69 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 1,955 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 93.0% on time here.
Cancellations run at 3.77%, against 1.81% nationally. That is about one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 3.3% 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.
At 160 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 8am–11am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 83.0% on time across 318 flights, 5 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 5 points of difference.
One caution: this is a thin sample. 318 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 YUM
Put together: the delay figures matter less here than the 3.77% cancellation rate. A late arrival costs you roughly 55 minutes; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 306 completed flights over 12 months sit behind that.
