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

PSA on SGF to CLT lands a B, 4 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 close to two hours on average. That is a workable record, not a spotless one. That rests on 619 flights, with a median arrival 11 minutes early.

The US average over the same twelve months is 77.6%, so there is little to separate PSA on SGF to CLT from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on SGF to CLT, 1,187 flights

These figures cover 619 flights between July 2025 and June 2026. The median arrival is 11 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 SGF to CLT

PSA flew 619 of the 1,187 flights on SGF to CLT, most of the route. Its 81.1% on time is 5 points worse than the route as a whole, which runs 86.1%. Ranked by on-time rate it is last 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 PSA runs best on this route

Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 619 flights.

5am–8am—
8am–11am14 flights—
11am–2pm377 flights84.6%
2pm–5pm—
5pm–8pm228 flights75.1%
8pm–5am—

Scale runs 65% 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 84.6% on time, ahead of 5pm–8pm at 75.1%. 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 11am–2pm window is the busiest, with 377 flights scheduled in it.

Across the year

PSA on SGF to CLT 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, 26 points below January, the best at 95.3%. 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 87.6% on time and Sunday the weakest at 76.1%. 12 points is a smaller lever than departure hour, but it is free.

Delay causes

Why PSA runs late on this route

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 13,000 reported delay minutes.

Late-arriving aircraft
39%
Carrier
35%
Extreme weather
19%
National Airspace System
6%

Extreme weather accounts for 19% 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 3.1 times the usual weather exposure. The split is drawn from 13,100 reported delay minutes.

39% 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 13,000 reported delay minutes here, that single category outweighs weather by 2 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 2.42% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

7.9% 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 close to two hours, 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 83.6% 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 SGF to CLT

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 81.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 604 completed flights over 12 months sit behind that.
