Delay causes
Why OO 3948 runs late
Carrier accounts for 73% of the 4,396 delay minutes carriers reported here, and the remaining four split what is left.
- 73%Carrier
- 20%Extreme weather
- 5%National Airspace System
- 1%Security
Extreme weather accounts for 20% 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 3.4 times the usual weather exposure. The split is drawn from 4,396 delay minutes reported on OO 3948.
Cancellations are rare at 0.39%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
8.6% 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 same number turns up on two other city pairs in the data, including OMA to MSP (74) and MSP to BIS (42), but none flew often enough under OO 3948 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MSP to OMA only.
One caution: this is a thin sample. 256 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 3948
