Delay causes
Why OO 5362 runs late
Carrier accounts for 51% of the 8,989 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Carrier
- 25%Late-arriving aircraft
- 18%National Airspace System
- 6%Extreme weather
The largest share of delay minutes, 51%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,568 of the 8,989 delay minutes reported here. The split is drawn from 8,989 delay minutes reported on OO 5362.
Cancellations run at 3.49%, 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
13.6% 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 two other city pairs in the data, including FNT to ORD (21) and SFO to MCI (19), but none flew often enough under OO 5362 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to MKE only.
One caution: this is a thin sample. 344 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 5362
For a booking, the cancellation rate is the figure to plan around on OO 5362: 3.49% of its 344 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.
