Delay causes
Why OO 5097 runs late
Late-arriving aircraft accounts for 50% of the 9,405 delay minutes carriers reported here, and the remaining four split what is left.

- 26%Extreme weather
- 15%National Airspace System
- 9%Carrier
- 0%Security
Extreme weather accounts for 26% 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 4.3 times the usual weather exposure. The split is drawn from 9,405 delay minutes reported on OO 5097.
Cancellations sit at 2.13% against a national 1.89%, which is ordinary. Diversions add another 1.82%.
Connections and routes
What a delay on this flight costs
12.7% 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 three other city pairs in the data, including SGU to DEN (26), HYS to DEN (26) and DEN to SUX (1), but none flew often enough under OO 5097 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to DIK only.
One caution: this is a thin sample. 329 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 5097
For a booking, OO 5097 is a flight to put a long connection behind. 12.7% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
