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

PSA on OKC to CLT earns an A. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 138 flights, with a median arrival 14 minutes early.

Set against the rest of the country, PSA's OKC to CLT record is 8 points better than the US average of 77.6%. That gap is worth roughly 83 fewer late arrivals for every thousand flights.

Every carrier on OKC to CLT, 794 flights

These figures cover 138 flights between July 2025 and June 2026. The median arrival is 14 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 OKC to CLT

PSA flew 138 of the 794 flights on OKC to CLT, about 17% of it. Its 85.9% on time is about level with the route as a whole at 85.3%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from American at 85.9% to SkyWest at 78.1%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

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 138 flights.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 85.9% on time across 138 flights.

Split by quarter, PSA on OKC to CLT logged 49 flights in Jul–Sep 2025, 26 flights in Oct–Dec 2025, 19 flights in Jan–Mar 2026 and 44 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 85.9% annual figure is the one to use.

Delay causes

Why PSA runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 46% of the 1,820 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% 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 1,820 reported delay minutes here, that single category outweighs weather by 46 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 1,820 reported delay minutes.

The largest share of delay minutes, 44%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 802 of the 1,820 delay minutes reported here.

Cancellations sit at 2.17% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

5.9% 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 an hour and a half, which a normal layover absorbs.

The 940 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 91.9% on time across 138 flights, 6 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 6 points of difference.

One caution: this is a thin sample. 138 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 OKC to CLT

Put together: treat all of this as provisional. 138 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 85.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 135 completed flights over 12 months sit behind that.
