Share of 312 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 116 departures that left 15 minutes late or more, only 7 made it up before arrival. In the other direction, 31 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 CAK.

Delay causes
Why OO 5352 runs late
Late-arriving aircraft accounts for 52% of the 14,000 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Late-arriving aircraft
- 22%National Airspace System
- 20%Carrier
- 7%Extreme weather
52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 14,000 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 14,269 delay minutes reported on OO 5352.
Cancellations run at 4.86%, against 1.89% nationally. That is about one flight in twenty 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
21.8% 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 SBN to ORD (103), SUN to DEN (18) and OMA to IAH (11), but none flew often enough under OO 5352 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to CAK only.
One caution: this is a thin sample. 329 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 5352
For a booking, the cancellation rate is the figure to plan around on OO 5352: 4.86% of its 329 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.
