Delay causes
Why OO 5022 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 12,000 reported delay minutes.
- 40%Late-arriving aircraft
- 34%Extreme weather
- 22%Carrier
- 4%National Airspace System
Extreme weather accounts for 34% 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 5.6 times the usual weather exposure. The split is drawn from 11,991 delay minutes reported on OO 5022.
Cancellations run at 4.04%, against 1.89% nationally. That is about one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
17.1% 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 four other city pairs in the data, including SGU to DEN (24), DEN to DDC (24) and CKB to IAD (11), but none flew often enough under OO 5022 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IAD to JST only.
One caution: this is a thin sample. 297 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 5022
For a booking, the cancellation rate is the figure to plan around on OO 5022: 4.04% of its 297 scheduled flights did not operate. A late arrival costs about 2.7 hours, but a cancellation costs the day, so leave a later option open.
