Departure window
When United 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 111 flights.
There are not enough flights in each departure window to split United's ORD to TUL record by time of day without the percentages moving on noise. The headline rate of 50.0% is the reliable figure here.

Delay causes
Why United runs late on this route
Late-arriving aircraft accounts for 63% of the 4,213 delay minutes carriers reported here, and the remaining four split what is left.
- 63%Late-arriving aircraft
- 15%Carrier
- 11%National Airspace System
- 10%Extreme weather
63% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,213 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 4,213 reported delay minutes.
Cancellations sit at 0.90% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
25.5% 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 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.
The return leg is a different operation and performs like one: it runs 84.1% on time across 108 flights, 34 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 34 points of difference.
One caution: this is a thin sample. 111 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 United on ORD to TUL
Put together: treat all of this as provisional. 111 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 50.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 110 completed flights over 12 months sit behind that.
