Delay causes
Why OO 5226 runs late
Carrier accounts for 58% of the 8,743 delay minutes carriers reported here, and the remaining four split what is left.
- 58%Carrier
- 20%Late-arriving aircraft
- 17%Extreme weather
- 5%National Airspace System
Extreme weather accounts for 17% 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 8,743 delay minutes reported on OO 5226.
Cancellations are rare at 0.30%, 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
8.7% 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 about 2.1 hours, which a normal layover absorbs.
The same number turns up on two other city pairs in the data, including BOI to DEN (21) and IAH to TUL (1), but none flew often enough under OO 5226 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to CPR only.
One caution: this is a thin sample. 336 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 5226
For a booking, read OO 5226 as 79.6% on time with 0.30% cancelled over 336 flights. Those are rates from the past twelve months, not a forecast for any particular day.
