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

PSA on DFW to GSP 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 a little over an hour. That rests on 234 flights, with a median arrival 12 minutes early.

Set against the rest of the country, PSA's DFW to GSP record is 8 points better than the US average of 77.6%. That gap is worth roughly 77 fewer late arrivals for every thousand flights.

These figures cover 234 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 DFW to GSP

PSA flew 234 of the 1,176 flights on DFW to GSP, about 20% of it. Its 85.3% on time is 14 points better than the route as a whole, which runs 71.6%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from PSA at 85.3% to American at 64.5%. 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 234 flights.

There are not enough flights in each departure window to split PSA's DFW to GSP record by time of day without the percentages moving on noise. The headline rate of 85.3% is the reliable figure here.

Across the year

PSA on DFW to GSP through the year

Jul–Sep 202592 flights89.0%
Oct–Dec 202585 flights84.5%
Jan–Mar 202612 flights—
Apr–Jun 202645 flights82.2%

Scale runs 75% to 95%. 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 85.3% on time across 234 flights.

Quarter by quarter PSA on DFW to GSP held fairly steady: 89.0% in Jul–Sep 2025, 84.5% in Oct–Dec 2025 and 82.2% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Across the week, Wednesday is the strongest day at 91.2% on time and Saturday the weakest at 70.0%. 21 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 47% of the 2,599 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.

47% 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 2,599 reported delay minutes here, that single category outweighs weather by 16 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 2,599 reported delay minutes.

The largest share of delay minutes, 40%, 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 1,044 of the 2,599 delay minutes reported here.

Cancellations are rare at 0.85%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and stage length

What a delay here costs

7.3% 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 a little over an hour, which a normal layover absorbs.

The 862 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 81.1% on time across 234 flights, 4 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 4 points of difference.

One caution: this is a thin sample. 234 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 DFW to GSP

Put together: treat all of this as provisional. 234 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 85.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 232 completed flights over 12 months sit behind that.
