PSA on DSM to DFW sits in the middle of the pack with a B−. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.3%. The late ones land an hour and a half behind schedule. That rests on 160 flights, with a median arrival 13 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate PSA on DSM to DFW from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
PSA against every carrier on DSM to DFW
PSA flew 160 of the 1,440 flights on DSM to DFW, about 11% of it. Its 75.7% on time is about level with the route as a whole at 74.3%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from Envoy at 88.4% to American at 69.7%. 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.

The latest arrival of the period was on 19 February 2026, 24 hours 35 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On four of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 19 February 2026 | 24 hours 35 minutes | Carrier |

Delay causes
Why PSA runs late on this route
Carrier accounts for 48% of the 3,604 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Carrier
- 38%Late-arriving aircraft
- 10%National Airspace System
- 3%Extreme weather
- 1%Security
38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,604 reported delay minutes here, that single category outweighs weather by 13 to one. The split is drawn from 3,604 reported delay minutes.
The largest share of delay minutes, 48%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,740 of the 3,604 delay minutes reported here.
Cancellations run at 4.38%, against 1.89% nationally. That is roughly one flight in 25 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
10.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 624 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.
The return leg is a different operation and performs like one: it runs 81.4% on time across 160 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. 160 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 DSM to DFW
Put together: the delay figures matter less here than the 4.38% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 5pm–8pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 152 completed flights over 12 months sit behind that.
