Every carrier on CHS to CLT, 2,534 flights
These figures cover 175 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 CHS to CLT
Envoy flew 175 of the 2,534 flights on CHS to CLT, about 7% of it. Its 92.3% on time is 9 points better than the route as a whole, which runs 83.8%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Envoy at 92.3% to PSA at 80.5%.
The two carriers here are closely matched: 4 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.

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.

- 8am–11am—
- 11am–2pm115 flights91.2%
- 2pm–5pm58 flights94.3%

Scale runs 85% to 100%. Rows with fewer than 30 flights show a dash.
The 2pm–5pm window is the strongest at 94.3% on time. The full set of windows spans 3 points.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 92.3% on time across 175 flights.
Split by quarter, Envoy on CHS to CLT 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 92.3% 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 66% of the 689 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.
- 66%Late-arriving aircraft
- 13%National Airspace System
- 12%Carrier
- 8%Extreme weather
66% 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 689 reported delay minutes here, that single category outweighs weather by 8 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 689 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 2.4% 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 2pm–5pm window matters as much as it does.
The return leg runs 90.5% 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 CHS to CLT
Put together: the delay figures matter less here than the 3.43% cancellation rate. A late arrival costs you roughly 55 minutes; a cancelled flight costs you the day. Book the 2pm–5pm 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.
