Share of 267 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 76 departures that left 15 minutes late or more, only 6 made it up before arrival. In the other direction, 20 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at ORD.

Delay causes
Why OO 5869 runs late
Late-arriving aircraft accounts for 52% of the 9,376 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Late-arriving aircraft
- 25%Carrier
- 21%National Airspace System
- 2%Extreme weather
52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 9,376 reported delay minutes here, that single category outweighs weather by 23 to one. The split is drawn from 9,376 delay minutes reported on OO 5869.
Cancellations run at 6.25%, against 1.89% nationally. That is about one flight in fifteen 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 routes
What a delay on this flight costs
17.6% 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 same number turns up on three other city pairs in the data, including DEN to AUS (6), SAT to ORD (1) and RAP to DEN (1), but none flew often enough under OO 5869 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to COU to ORD only.
One caution: this is a thin sample. 288 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 OO 5869
For a booking, the cancellation rate is the figure to plan around on OO 5869: 6.25% of its 288 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
