Envoy on ORD to SGF lands a B, level with the national rate of 77.3%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by about an hour on average. That rests on 1,116 flights, with a median arrival 10 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Envoy on ORD to SGF from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

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 16 points, against half a point between the best and worst carrier.
- 5am–8am2 flights—
- 8am–11am352 flights84.3%
- 11am–2pm122 flights85.8%
- 2pm–5pm183 flights75.6%
- 5pm–8pm274 flights69.4%
- 8pm–5am183 flights73.8%
Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 85.8% on time, ahead of 5pm–8pm at 69.4%. 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 8am–11am window is the busiest, with 352 flights scheduled in it.
Across the year
Envoy on ORD to SGF through the year
December is the weak month at 61.1% on time, against 85.6% in May. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. July was the busiest month here, with 120 flights.
Across the week, Tuesday is the strongest day at 83.6% on time and Friday the weakest at 72.1%, a spread of 12 points.

Delay causes
Why Envoy runs late on this route
Late-arriving aircraft accounts for 58% of the 16,000 delay minutes carriers reported here, and the remaining four split what is left.
- 58%Late-arriving aircraft
- 21%National Airspace System
- 11%Extreme weather
- 10%Carrier
58% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 16,000 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 15,770 reported delay minutes.
Cancellations run at 2.60%, against 1.89% nationally. That is about one flight in 40 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
8.6% 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.
At 438 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 76.3% on time across 1,118 flights, within about a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
The sample behind these figures is 1,116 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
What to do with this
Booking Envoy on ORD to SGF
Put together: the calendar is the biggest lever here, not the carrier or the hour. May runs 85.6% on time and December 61.1%, a swing of 24 points. If the dates move at all, move them out of December before you think about anything else. 1,082 completed flights over 12 months sit behind that.
