Carrier by carrier
PSA against every carrier on STL to DFW

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 STL to DFW record by time of day without the percentages moving on noise. The headline rate of 67.3% is the reliable figure here.

Delay causes
Why PSA runs late on this route
Late-arriving aircraft accounts for 47% of the 3,809 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Late-arriving aircraft
- 41%National Airspace System
- 9%Carrier
- 3%Extreme weather
47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,809 reported delay minutes here, that single category outweighs weather by 14 to one. The split is drawn from 3,809 reported delay minutes.
41% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,559 minutes out of 3,809, against a national NAS share of 21%.
Cancellations run at 3.51%, against 1.89% 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
14.5% 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 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 72.2% on time across 114 flights, 5 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 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 STL to DFW
Put together: the delay figures matter less here than the 3.51% cancellation rate. A late arrival costs you close to two hours; a cancelled flight costs you the day. Book the 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 110 completed flights over 12 months sit behind that.
