Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with PSA Airlines.

PSA on CLT to SGF lands a B, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about 55 minutes on average. That is a workable record, not a spotless one. That rests on 619 flights, with a median arrival 12 minutes early.

Set against the rest of the country, PSA's CLT to SGF record is 6 points better than the US average of 77.6%. That gap is worth roughly 60 fewer late arrivals for every thousand flights.

Every carrier on CLT to SGF, 1,187 flights

These figures cover 619 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

PSA against every carrier on CLT to SGF

PSA flew 619 of the 1,187 flights on CLT to SGF, most of the route. Its 83.6% on time is 2 points better than the route as a whole, which runs 81.9%. Ranked by on-time rate it is first 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.

Departure window

When PSA runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 11 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–11am317 flights86.3%
11am–2pm74 flights89.0%
2pm–5pm228 flights78.2%
5pm–8pm—
8pm–5am—

Scale runs 70% 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 89.0% on time, ahead of 2pm–5pm at 78.2%. 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 317 flights scheduled in it.

Across the year

PSA on CLT to SGF through the year

Darker means more delays. Figures are on-time percentages.January best, June worst

June is the worst month at 69.0% on time, 22 points below January, the best at 90.7%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. August was the busiest month here, with 84 flights.

Across the week, Wednesday is the strongest day at 89.9% on time and Sunday the weakest at 77.3%. 13 points is a smaller lever than departure hour, but it is free.

Delay causes

Why PSA runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 45% of the 5,384 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.

Extreme weather
6%

45% 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 5,384 reported delay minutes here, that single category outweighs weather by 7 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 5,384 reported delay minutes.

Cancellations sit at 2.42% against a national 1.81%, which is ordinary. Diversions add another 0.81%.

Connections and stage length

What a delay here costs

5.8% 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 about 55 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 runs 81.1% on time across 619 flights, within 3 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. 619 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 PSA on CLT to SGF

Put together: treat all of this as provisional. 619 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 83.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 599 completed flights over 12 months sit behind that.
