Delay causes
Why OO 4136 runs late
Carrier accounts for 80% of the 5,992 delay minutes carriers reported here, and the remaining four split what is left.
- 80%Carrier
- 16%Extreme weather
- 4%National Airspace System
Extreme weather accounts for 16% 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 2.7 times the usual weather exposure. The split is drawn from 5,992 delay minutes reported on OO 4136.
Cancellations sit at 1.18% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
11.1% 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 DTW to CMH (8) and CMH to DTW (8), but none flew often enough under OO 4136 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MOT to MSP only.
One caution: this is a thin sample. 255 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 4136
For a booking, read OO 4136 as 80.2% on time with 1.18% cancelled over 255 flights. Those are rates from the past twelve months, not a forecast for any particular day.
