Delay causes
Why OO 3791 runs late
Carrier accounts for 51% of the 5,463 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Carrier
- 36%Extreme weather
- 13%National Airspace System
Extreme weather accounts for 36% 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 6.0 times the usual weather exposure. The split is drawn from 5,463 delay minutes reported on OO 3791.
Cancellations sit at 1.10% against a national 1.89%, which is ordinary. Diversions add another 0.82%.
Connections and routes
What a delay on this flight costs
8.7% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
The 694 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on one other city pair in the data, including ATL to LEX (1), but none flew often enough under OO 3791 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MSP to OKC only.
One caution: this is a thin sample. 364 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 3791
