Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with PSA Airlines.
PSA on CHA to DFW carries a cancellation problem, not just a delay problem: 3.5% of scheduled flights never operate, against 1.8% nationally. Of the ones that do fly, about four flights in five arrive on time, worth a B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 1,239 flights, with a median arrival 13 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate PSA on CHA 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 CHA to DFW, 1,640 flights
These figures cover 1,239 flights between July 2025 and June 2026. Beyond the headline rate, 9.8% 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 CHA to DFW
PSA flew 1,239 of the 1,640 flights on CHA to DFW, most of the route. Its 79.0% on time is about level with the route as a whole at 78.6%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from Envoy at 84.3% to American at 62.9%. Three 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 matters more here than the choice of carrier. The gap between the best and worst window is 17 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am456 flights85.2%
- 8am–11am84 flights86.4%
- 11am–2pm163 flights80.6%
- 2pm–5pm245 flights74.3%
- 5pm–8pm189 flights70.2%
- 8pm–5am102 flights69.6%
Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 86.4% of the time, against 69.6% for the overnight window. That is 17 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 456 flights scheduled in it.
Across the year
PSA on CHA to DFW through the year
December is the weak month at 71.5% on time, against 84.8% in February. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. November was the busiest month here, with 144 flights.
Across the week, Wednesday is the strongest day at 84.2% on time and Sunday the weakest at 70.3%. 14 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 48% of the 27,000 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.
- 48%Late-arriving aircraft
- 38%Carrier
- 8%National Airspace System
- 6%Extreme weather
48% 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 27,000 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 27,352 reported delay minutes.
The largest share of delay minutes, 38%, 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 10,000 of the 27,000 delay minutes reported here.
Cancellations run at 3.47%, against 1.81% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
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. 9.8% 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 695 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 72.5% on time across 1,242 flights, 7 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 7 points of difference.
The sample behind these figures is 1,239 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
What to do with this
Booking PSA on CHA to DFW
Put together: the delay figures matter less here than the 3.47% cancellation rate. A late arrival costs you close to two hours; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 1,189 completed flights over 12 months sit behind that.
