Envoy Air at Phoenix earns a A+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.4%. When something does go wrong the average delay runs roughly 50 minutes. That rests on 9,964 flights, of which Delta Air Lines flew 10,708 at 86.6% on time.
Measured against the airport rather than the country, Envoy Air runs 6 points ahead of the 79.1% weighted average across all carriers at PHX. That is the comparison worth making: every operator here works the same runways, the same airspace and the same weather.

#2
Of 9 carriers clearing the floor at PHX
These figures cover 9,964 flights between June 2025 and May 2026. The median arrival is 7 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.
Against the competition
Every carrier at PHX, ranked
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 86.6% of the time; JetBlue Airways manages 70.6%. Sample sizes sit next to every figure, because a two-point gap across 1,139 flights means less than a ten-point one.

| JetBlue Airways | 1,139 | 70.6% | 68 min | 2.37% | C |
The spread between Delta and JetBlue is 16 points, wide enough that it should decide the booking. On a hundred trips that is 16 more arrivals inside the on-time window.
Route by route
Where Envoy Air flies from PHX
Envoy Air operates 25 routes out of PHX with enough volume to report. Route records inside one carrier at one airport still spread widely, because a short shuttle and a transcontinental have very different exposure to a late inbound.

Departure window
Best time of day for this operation
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 11 points, against 16 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am592 flights93.1%
- 8am–11am2,389 flights88.3%
- 11am–2pm1,792 flights85.6%
- 2pm–5pm2,218 flights83.3%
- 5pm–8pm1,915 flights82.6%
- 8pm–5am1,058 flights82.9%
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 93.1% of the time, against 82.6% for the evening window. That is 11 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on.
Across the year
Seasonal pattern
June is the worst month at 79.7% on time, 11 points below April, the best at 90.7%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck.
Delay causes
What holds this operation up
- 56%Late-arriving aircraft
- 23%Carrier
- 19%National Airspace System
- 2%Extreme weather
- 0%Security
56% 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 71,000 reported delay minutes here, that single category outweighs weather by 31 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.
Cancellations are rare at 0.70%, below the national 1.80% 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.
Badly late arrivals are rare here: only 3.8% land an hour or more behind schedule, against 8.2% 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 sample behind these figures is 9,964 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
Put together: avoid the 5pm–8pm departure. It runs 82.6% on time against 93.1% for the 5am–8am slot, and that 11 points is the largest single thing you control here. Delta Air Lines is the strongest operator if the fares are close.
Common questions
Envoy Air at PHX
How often is Envoy Air at PHX delayed?
About one flight in seven arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 14.7% of the 9,964 flights in this analysis, against 22.6% nationally. Delayed flights are late by roughly 50 minutes on average.
Which airline is most reliable on Envoy Air at PHX?
Delta Air Lines leads at 86.6% on time across 10,708 flights. JetBlue Airways is at the other end on 70.6%, a gap of 16 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on Envoy Air at PHX?
The 5am–8am departure window is the strongest at 93.1% on time. The 5pm–8pm window is the weakest at 82.6%, 11 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are June delays on Envoy Air at PHX?
June is the weakest month at 79.7% on time, compared with 90.7% in April. Across the year that is 11 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
