Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with PSA Airlines.
PSA on GSP 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 an hour and a half on average. That is a workable record, not a spotless one. That rests on 234 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 GSP to DFW from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 234 flights between July 2025 and June 2026. Beyond the headline rate, 10.6% 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 GSP to DFW
PSA flew 234 of the 1,178 flights on GSP to DFW, about 20% of it. Its 81.1% on time is 6 points better than the route as a whole, which runs 75.3%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from PSA at 81.1% to American at 73.6%. 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 GSP to DFW record by time of day without the percentages moving on noise. The headline rate of 81.1% is the reliable figure here.
Across the year
PSA on GSP to DFW through the year
- Jul–Sep 202592 flights84.4%
- Oct–Dec 202585 flights79.5%
- Jan–Mar 202612 flights—
- Apr–Jun 202645 flights83.3%
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 234 flights.
Quarter by quarter PSA on GSP to DFW held fairly steady: 84.4% in Jul–Sep 2025, 79.5% in Oct–Dec 2025 and 83.3% in Apr–Jun 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
Across the week, Tuesday is the strongest day at 90.6% on time and Saturday the weakest at 69.2%. 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 58% of the 3,783 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.
- 58%Late-arriving aircraft
- 23%Carrier
- 12%Extreme weather
- 7%National Airspace System
Extreme weather accounts for 12% 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 1.9 times the usual weather exposure. The split is drawn from 3,783 reported delay minutes.
58% 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 3,783 reported delay minutes here, that single category outweighs weather by 5 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 1.28% against a national 1.81%, which is ordinary. Diversions add another 1.71%.
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. 10.6% 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 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 85.3% on time across 234 flights, 4 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 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 GSP to DFW
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 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. 227 completed flights over 12 months sit behind that.
