Share of 334 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 120 departures that left 15 minutes late or more, only 11 made it up before arrival. In the other direction, 54 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 5675 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 15,000 reported delay minutes.
- 39%Late-arriving aircraft
- 37%National Airspace System
- 15%Carrier
- 9%Extreme weather
39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 15,000 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 14,725 delay minutes reported on OO 5675.
Cancellations run at 5.11%, against 1.89% nationally. That is about 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
20.1% 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.
Every one of the 352 flights under OO 5675 in the data flew SBN to ORD. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 352 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 5675
For a booking, the cancellation rate is the figure to plan around on OO 5675: 5.11% of its 352 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
