Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Envoy Air.
Envoy on CLT to SGF lands a B, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by roughly 50 minutes on average. That is a workable record, not a spotless one. That rests on 568 flights, with a median arrival 7 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate Envoy on CLT to SGF from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on CLT to SGF, 1,187 flights
These figures cover 568 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 SGF
Envoy flew 568 of the 1,187 flights on CLT to SGF, about 48% of it. Its 80.1% on time is 2 points worse than the route as a whole, which runs 81.9%. Ranked by on-time rate it is last of two carriers on the route, where the range runs from PSA at 83.6% to Envoy at 80.1%.
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.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| PSA Airlines | 619 | 83.6% | 55 min | 2.42% | B |
| Envoy Air (this page) | 568 | 80.1% | 52 min | 1.58% | B |
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 19 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–8am—
- 8am–11am18 flights—
- 11am–2pm120 flights89.9%
- 2pm–5pm70 flights85.7%
- 5pm–8pm126 flights82.5%
- 8pm–5am234 flights71.3%
Scale runs 65% 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 89.9% on time, ahead of 8pm–5am at 71.3%. 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 8pm–5am window is the busiest, with 234 flights scheduled in it.
Across the year
Envoy on CLT to SGF through the year
Delays peak in November, when the on-time rate falls to 73.7%. January is the strongest month at 87.5%. Moving a flexible trip across that boundary buys 14 points. May was the busiest month here, with 71 flights.
Across the week, Tuesday is the strongest day at 91.9% on time and Saturday the weakest at 70.7%. 21 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 46% of the 5,788 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.
- 46%Late-arriving aircraft
- 26%Carrier
- 15%National Airspace System
- 13%Extreme weather
Extreme weather accounts for 13% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.0 times the usual weather exposure. The split is drawn from 5,788 reported delay minutes.
46% 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 5,788 reported delay minutes here, that single category outweighs weather by 4 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 sit at 1.58% against a national 1.81%, which is ordinary. Diversions add another 0.35%.
Connections and stage length
What a delay here costs
5.0% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last roughly 50 minutes, which a normal layover absorbs.
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 91.4% on time across 568 flights, 11 points above 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 CLT to SGF
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 80.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 557 completed flights over 12 months sit behind that.
