Delay causes
Why OO 5489 runs late
Late-arriving aircraft accounts for 58% of the 9,296 delay minutes carriers reported here, and the remaining four split what is left.
- 58%Late-arriving aircraft
- 23%National Airspace System
- 16%Carrier
- 3%Extreme weather
58% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 9,296 reported delay minutes here, that single category outweighs weather by 19 to one. The split is drawn from 9,296 delay minutes reported on OO 5489.
Cancellations run at 4.21%, against 1.89% nationally. That is about one flight in 25 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
16.4% 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 two other city pairs in the data, including MCI to LAX (97) and GSP to ORD (1), but none flew often enough under OO 5489 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SBN to ORD only.
One caution: this is a thin sample. 261 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 5489
For a booking, the cancellation rate is the figure to plan around on OO 5489: 4.21% of its 261 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
