Share of 240 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 72 departures that left 15 minutes late or more, only 3 made it up before arrival. In the other direction, 51 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 5466 runs late
National Airspace System accounts for 47% of the 9,404 delay minutes carriers reported here, and the remaining four split what is left.
- 47%National Airspace System
- 31%Late-arriving aircraft
- 21%Carrier
- 1%Extreme weather
47% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 4,388 minutes out of 9,404, against a national NAS share of 21%. The split is drawn from 9,404 delay minutes reported on OO 5466.
Cancellations run at 7.69%, against 1.89% nationally. That is roughly 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
19.2% 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 two other city pairs in the data, including SCE to ORD (47) and SFO to MFR (3), but none flew often enough under OO 5466 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to FWA to ORD only.
One caution: this is a thin sample. 260 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 5466
For a booking, the cancellation rate is the figure to plan around on OO 5466: 7.69% of its 260 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.
