Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with PSA Airlines.

PSA on TUL to ORD earns a D−, which is as low as this site's scale goes for a reason. Only 56.8% of flights arrive inside the 15-minute window, 21 points worse than the national rate of 77.6%. Late arrivals average close to two hours. Treat any tight connection here as a coin flip. That rests on 153 flights. The strongest carrier on the route with a full sample, SkyWest Airlines, flew 1,057 at 78.4% on time.

The national on-time rate over the same period is 77.6%, so PSA on TUL to ORD runs 21 points behind the country as a whole. Across a thousand flights that is about 208 extra late arrivals.

These figures cover 153 flights between July 2025 and June 2026. Beyond the headline rate, 22.3% 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 TUL to ORD

PSA flew 153 of the 2,155 flights on TUL to ORD, about 7% of it. Its 56.8% on time is 19 points worse than the route as a whole, which runs 76.1%. Ranked by on-time rate it is last of five carriers on the route, where the range runs from United at 84.8% to PSA at 56.8%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The two carriers here are closely matched: 3 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

Envoy Air cancels 3.2% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

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 153 flights.

There are not enough flights in each departure window to split PSA's TUL to ORD record by time of day without the percentages moving on noise. The headline rate of 56.8% is the reliable figure here.

Across the year

PSA on TUL to ORD through the year

Jul–Sep 202564 flights60.7%
Oct–Dec 202584 flights53.7%
Jan–Mar 20265 flights—

Scale runs 45% to 65%. Rows with fewer than 30 flights show a dash.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 56.8% on time across 153 flights.

Split by quarter, PSA on TUL to ORD logged 64 flights in Jul–Sep 2025, 84 flights in Oct–Dec 2025 and 5 flights in Jan–Mar 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 56.8% annual figure is the one to use.

Delay causes

Why PSA runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 77% of the 7,620 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.

77% 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 7,620 reported delay minutes here, that single category outweighs weather by 33 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 7,620 reported delay minutes.

Cancellations run at 3.27%, 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. 22.3% 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 585 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 67.1% on time across 153 flights, 10 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 10 points of difference.

One caution: this is a thin sample. 153 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 TUL to ORD

Put together: the delay figures matter less here than the 3.27% 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. 148 completed flights over 12 months sit behind that.
