Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Envoy Air.
Envoy on SGF to CLT 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 14 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 568 flights, with a median arrival 12 minutes early.
Set against the rest of the country, Envoy's SGF to CLT record is 14 points better than the US average of 77.6%. That gap is worth roughly 138 fewer late arrivals for every thousand flights.

These figures cover 568 flights between July 2025 and June 2026. The median arrival is 12 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 SGF to CLT
Envoy flew 568 of the 1,187 flights on SGF to CLT, about 48% of it. Its 91.4% on time is 5 points better than the route as a whole, which runs 86.1%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from Envoy at 91.4% to PSA at 81.1%.
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 13 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–8am296 flights94.2%
- 8am–11am69 flights96.9%
- 11am–2pm53 flights90.6%
- 2pm–5pm150 flights83.9%
- 5pm–8pm—
- 8pm–5am—
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 96.9% of the time, against 83.9% for the afternoon window. That is 13 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 296 flights scheduled in it.
Across the year
Envoy on SGF to CLT through the year
September is the best month on the calendar at 100.0% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. May was the busiest month here, with 71 flights.
Across the week, Tuesday is the strongest day at 98.6% on time and Saturday the weakest at 84.2%. 14 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 55% of the 2,954 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.

- 23%Carrier
- 16%National Airspace System
- 5%Extreme weather
- 1%Security
55% 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 2,954 reported delay minutes here, that single category outweighs weather by 12 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 2,954 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 96.9% on time here.
Cancellations sit at 1.41% against a national 1.81%, which is ordinary. Diversions add another 0.35%.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 3.2% 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.
The 708 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 is a different operation and performs like one: it runs 80.1% on time across 568 flights, 11 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 11 points of difference.
One caution: this is a thin sample. 568 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 SGF to CLT
Put together: treat all of this as provisional. 568 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 91.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 558 completed flights over 12 months sit behind that.
