Delay causes
Why OO 5392 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 5,669 reported delay minutes.
- 36%Carrier
- 33%National Airspace System
- 21%Late-arriving aircraft
- 9%Extreme weather
The largest share of delay minutes, 36%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,057 of the 5,669 delay minutes reported here. The split is drawn from 5,669 delay minutes reported on OO 5392.
Cancellations run at 5.60%, against 1.89% nationally. That is roughly one flight in twenty 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
12.3% 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 693 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on five other city pairs in the data, including MSN to ORD (30), IAH to MAF (24) and ORD to MEM (21), but none flew often enough under OO 5392 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to OKC only.
One caution: this is a thin sample. 268 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 5392
For a booking, the cancellation rate is the figure to plan around on OO 5392: 5.60% of its 268 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
