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

PSA on CHS to DFW 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 114 flights, with a median arrival 15 minutes early.

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

Every carrier on CHS to DFW, 1,250 flights

These figures cover 114 flights between July 2025 and June 2026. Beyond the headline rate, 9.0% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Carrier by carrier

PSA against every carrier on CHS to DFW

PSA flew 114 of the 1,250 flights on CHS to DFW, about 9% of it. Its 81.1% on time is about level with the route as a whole at 80.5%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from Envoy at 94.0% to Frontier at 77.8%. Two 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 114 flights.

5am–8am37 flights86.5%
8am–11am—
11am–2pm41 flights78.9%
2pm–5pm36 flights77.8%
5pm–8pm—
8pm–5am—

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 86.5% of the time, against 77.8% for the afternoon window. That is 9 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 41 flights scheduled in it.

Across the year

PSA on CHS to DFW through the year

Jul–Sep 202573 flights82.2%
Apr–Jun 202641 flights78.9%

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 81.1% on time across 114 flights.

Split by quarter, PSA on CHS to DFW logged 73 flights in Jul–Sep 2025 and 41 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 81.1% annual figure is the one to use.

Delay causes

Why PSA runs late on this route

One category carries most of the weight here. Carrier accounts for 46% of the 2,175 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.

Carrier
46%
Late-arriving aircraft
43%
National Airspace System
6%
Extreme weather
5%

43% 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 2,175 reported delay minutes here, that single category outweighs weather by 8 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 2,175 reported delay minutes.

The largest share of delay minutes, 46%, 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 993 of the 2,175 delay minutes reported here.

Cancellations sit at 1.75% against a national 1.81%, which is ordinary. Diversions add another 0.88%.

Connections and stage length

What a delay here costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.0% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The 987 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 75.9% on time across 113 flights, 5 points below 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 5 points of difference.

One caution: this is a thin sample. 114 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 CHS to DFW

Put together: treat all of this as provisional. 114 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. 111 completed flights over 12 months sit behind that.
