Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Envoy Air.
Envoy on CLT to SGF lands a B, 4 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That rests on 646 flights, with a median arrival 8 minutes early.
The US average over the same twelve months is 77.3%, 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.

These figures cover 646 flights between September 2025 and August 2026. The median arrival is 8 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.

Book the morning departure. Flights leaving between 8am–11am arrive on time 92.7% of the time, against 71.0% for the overnight window. That is 22 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8pm–5am window is the busiest, with 225 flights scheduled in it.

Share of 635 completed flights by arrival against schedule.
18 of 100 late departures made up the time and arrived on time, 18% of them. In the other direction, 39 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at SGF.
The worst days
Worst days for Envoy on CLT to SGF
The latest arrival of the period was on 4 August 2026, 4 hours 16 minutes behind schedule; most of its delay minutes were filed as extreme weather. The five worst days are spread across August, May, March and September, with no single month standing out.

| 4 August 2026 | 4 hours 16 minutes | Extreme weather |
| 6 May 2026 | 3 hours 40 minutes | Extreme weather |

Delay causes
Why Envoy runs late on this route
Late-arriving aircraft accounts for 46% of the 6,884 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Late-arriving aircraft
- 25%Carrier
- 15%Extreme weather
- 14%National Airspace System
Extreme weather accounts for 15% 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 2.4 times the usual weather exposure. The split is drawn from 6,884 reported delay minutes.
46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,884 reported delay minutes here, that single category outweighs weather by 3 to one.
Cancellations sit at 1.39% against a national 1.89%, which is ordinary. Diversions add another 0.31%.
Connections and stage length
What a delay here costs
5.7% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, 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.
The return leg is a different operation and performs like one: it runs 91.2% on time across 646 flights, 10 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 10 points of difference.
One caution: this is a thin sample. 646 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. 646 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 80.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 635 completed flights over 12 months sit behind that.
