The latest arrival of the period was on 19 September 2025, 3 hours 10 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The five worst days are spread across September, April, February and March, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 19 September 2025 | 3 hours 10 minutes | National Airspace System |
| 2 April 2026 | 2 hours 55 minutes | Extreme weather |
| 14 February 2026 | 2 hours 52 minutes | Late-arriving aircraft |

Delay causes
Why PSA runs late on this route
Late-arriving aircraft accounts for 47% of the 1,994 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Late-arriving aircraft
- 31%Carrier
- 14%National Airspace System
- 8%Extreme weather
47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,994 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 1,994 reported delay minutes.
Cancellations run at 2.50%, against 1.89% nationally. That is about one flight in 40 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
9.0% 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 75.7% on time across 160 flights, 6 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 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 DFW to DSM
Put together: treat all of this as provisional. 160 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 81.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 156 completed flights over 12 months sit behind that.
