Carrier by carrier
PSA against every carrier on DFW to STL
PSA flew 114 of the 2,392 flights on DFW to STL, about 5% of it. Its 72.2% on time is 3 points better than the route as a whole, which runs 69.7%. Ranked by on-time rate it is number four of five carriers on the route, where the range runs from Envoy at 89.3% to American at 66.1%. 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 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 114 flights.
There are not enough flights in each departure window to split PSA's DFW to STL record by time of day without the percentages moving on noise. The headline rate of 72.2% is the reliable figure here.

The worst days
Worst days for PSA on DFW to STL
The latest arrival of the period was on 8 August 2026, 3 hours 24 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. Four of the five worst days fell in June 2026.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 8 August 2026 | 3 hours 24 minutes | Late-arriving aircraft |
| 28 June 2026 | 2 hours 33 minutes | Late-arriving aircraft |
| 19 June 2026 | 2 hours 12 minutes | Extreme weather |

Delay causes
Why PSA runs late on this route
Late-arriving aircraft accounts for 71% of the 1,707 delay minutes carriers reported here, and the remaining four split what is left.
- 71%Late-arriving aircraft
- 16%Carrier
- 8%Extreme weather
- 5%National Airspace System
71% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,707 reported delay minutes here, that single category outweighs weather by 9 to one. The split is drawn from 1,707 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 71.6% on time here.
Cancellations run at 4.39%, 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
9.3% 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 550 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 67.3% on time across 114 flights, 5 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 5 points of difference.
One caution: this is a thin sample. 114 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 STL
Put together: the delay figures matter less here than the 4.39% cancellation rate. A late arrival costs you about an hour; 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. 108 completed flights over 12 months sit behind that.
