Time lost at the gate mostly stays lost. Of 116 departures that left 15 minutes late or more, only 10 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 FWA.

Delay causes
Why OO 5448 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 11,000 reported delay minutes.
- 33%Carrier
- 32%Late-arriving aircraft
- 25%National Airspace System
- 9%Extreme weather
No single cause dominates. carrier at 33%, late-arriving aircraft at 32% and national airspace system at 25% split the 11,000 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 11,096 delay minutes reported on OO 5448.
Cancellations sit at 1.92% against a national 1.89%, which is ordinary. Diversions add another 0.55%.
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 one other city pair in the data, including FAR to ORD (47), but none flew often enough under OO 5448 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to FWA only.
One caution: this is a thin sample. 365 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 5448
For a booking, OO 5448 is a flight to put a long connection behind. 17.1% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
