Share of 321 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 44 departures that left 15 minutes late or more, only 1 made it up before arrival. In the other direction, 28 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.
The worst days
Worst days for OO 5020
The latest arrival of the period was on 30 December 2025, 13 hours 30 minutes behind schedule; most of its delay minutes were filed as extreme weather. The five worst days are spread across December, March, August and January, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 30 December 2025 | 13 hours 30 minutes | Extreme weather |
| 7 December 2025 | 10 hours 1 minute | National Airspace System |

Delay causes
Why OO 5020 runs late
Carrier accounts for 46% of the 9,419 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Carrier
- 26%National Airspace System
- 16%Late-arriving aircraft
- 12%Extreme weather
Extreme weather accounts for 12% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.0 times the usual weather exposure. The split is drawn from 9,419 delay minutes reported on OO 5020.
Cancellations run at 3.29%, 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 routes
What a delay on this flight costs
11.8% 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 ORD to CMX (85), DEN to ATY (31) and ORD to CIU (5), but none flew often enough under OO 5020 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to JLN to ORD only.
One caution: this is a thin sample. 334 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 5020
For a booking, the cancellation rate is the figure to plan around on OO 5020: 3.29% of its 334 scheduled flights did not operate. A late arrival costs about 2.2 hours, but a cancellation costs the day, so leave a later option open.
