These figures cover 349 flights between July 2025 and June 2026. The median arrival is 6 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 CLT to EYW

Envoy flew 349 of the 1,262 flights on CLT to EYW, about 28% of it. Its 85.7% on time is 3 points better than the route as a whole, which runs 82.7%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from Envoy at 85.7% to American at 81.6%.

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 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 349 flights.

5am–8am—
8am–11am—
11am–2pm237 flights87.9%
2pm–5pm112 flights81.1%
5pm–8pm—
8pm–5am—

Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.

The best window here is not the first bank but the 11am–2pm slot at 87.9% on time, ahead of 2pm–5pm at 81.1%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 11am–2pm window is the busiest, with 237 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 85.7% on time across 349 flights.

Quarter by quarter Envoy on CLT to EYW held fairly steady: 84.5% in Jul–Sep 2025, 87.2% in Oct–Dec 2025, 81.6% in Jan–Mar 2026 and 90.0% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Across the week, Wednesday is the strongest day at 92.3% on time and Sunday the weakest at 80.0%. 12 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Envoy runs late on this route

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 2,078 reported delay minutes.

Late-arriving aircraft
39%
Carrier
39%
National Airspace System
21%
Extreme weather
1%

39% 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 2,078 reported delay minutes here, that single category outweighs weather by 39 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 2,078 reported delay minutes.

The largest share of delay minutes, 39%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 812 of the 2,078 delay minutes reported here.

Cancellations sit at 1.15% against a national 1.81%, which is ordinary. Diversions add another 0.57%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 2.3% 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.

The 736 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 runs 85.3% on time across 349 flights, within half a point 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. 349 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 CLT to EYW

Put together: treat all of this as provisional. 349 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 85.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 343 completed flights over 12 months sit behind that.
