Across the year

OO 4698 quarter by quarter

Share of 297 completed flights by arrival against schedule.

Time lost at the gate mostly stays lost. Of 86 departures that left 15 minutes late or more, only 3 made it up before arrival. In the other direction, 30 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at ORD.

Delay causes

Why OO 4698 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 13,000 reported delay minutes.

Late-arriving aircraft
34%
Carrier
33%
National Airspace System
28%
Extreme weather
5%

No single cause dominates. late-arriving aircraft at 34%, carrier at 33% and national airspace system at 28% split the 13,000 reported delay minutes between them. An even spread like this usually means the operation is running close to its designed capacity with no one obvious weak point, and it is the hardest pattern for a traveller to route around. The split is drawn from 13,249 delay minutes reported on OO 4698.

Cancellations run at 8.59%, against 1.89% nationally. That is about one flight in twelve 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

22.9% 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 ORD to GEG (9), LAX to AUS (2) and LAX to LAS (1), but none flew often enough under OO 4698 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CAK to ORD only.

One caution: this is a thin sample. 326 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 4698

For a booking, the cancellation rate is the figure to plan around on OO 4698: 8.59% of its 326 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
