Envoy on CLT to CHS 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 45 minutes. That rests on 175 flights. The strongest carrier on the route with a full sample, PSA Airlines, flew 570 at 76.6% on time.

Set against the rest of the country, Envoy's CLT to CHS record is 13 points better than the US average of 77.6%. That gap is worth roughly 129 fewer late arrivals for every thousand flights.

Every carrier on CLT to CHS, 2,536 flights

These figures cover 175 flights between July 2025 and June 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.

Carrier by carrier

Envoy against every carrier on CLT to CHS

Envoy flew 175 of the 2,536 flights on CLT to CHS, about 7% of it. Its 90.5% on time is 14 points better than the route as a whole, which runs 76.3%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Envoy at 90.5% to American at 74.8%.

The two carriers here are closely matched: 2 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. PSA tops the table at 76.6%, 2 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 175 flights.

5am–8am—
8am–11am39 flights87.2%
11am–2pm134 flights93.0%
2pm–5pm2 flights—
5pm–8pm—

Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.

The best window here is not the first bank but the 11am–2pm slot at 93.0% on time, ahead of 8am–11am at 87.2%. 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 134 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 90.5% on time across 175 flights.

Split by quarter, Envoy on CLT to CHS logged 88 flights in Oct–Dec 2025, 82 flights in Jan–Mar 2026 and 5 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 90.5% 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 61% of the 708 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.

Late-arriving aircraft
61%
National Airspace System
18%
Carrier
18%
Extreme weather
3%

61% 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 708 reported delay minutes here, that single category outweighs weather by 19 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 708 reported delay minutes.

Cancellations run at 3.43%, against 1.81% nationally. That is about one flight in 30 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 1.2% 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 168 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 11am–2pm window matters as much as it does.

The return leg runs 92.3% on time across 175 flights, within 2 points 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. 175 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 CHS

Put together: the delay figures matter less here than the 3.43% cancellation rate. A late arrival costs you about 45 minutes; a cancelled flight costs you the day. Book the 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 169 completed flights over 12 months sit behind that.
