Delay causes
Why OO 5107 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 8,470 reported delay minutes.
- 30%Late-arriving aircraft
- 27%Extreme weather
- 25%Carrier
- 17%National Airspace System
Extreme weather accounts for 27% 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 4.5 times the usual weather exposure. The split is drawn from 8,470 delay minutes reported on OO 5107.
Cancellations are rare at 0.28%, 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
10.6% 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 five other city pairs in the data, including LBF to DEN (75), SUX to DEN (36) and HYS to DEN (25), but none flew often enough under OO 5107 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to SLN only.
One caution: this is a thin sample. 362 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 5107
For a booking, read OO 5107 as 73.9% on time with 0.28% cancelled over 362 flights. Those are rates from the past twelve months, not a forecast for any particular day.
