Delay causes

Why OO 5878 runs late

Late-arriving aircraft accounts for 51% of the 7,214 delay minutes carriers reported here, and the remaining four split what is left.

Extreme weather

51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,214 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 7,214 delay minutes reported on OO 5878.

Cancellations are rare at 0.27%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

9.4% 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 364 flights under OO 5878 in the data flew SAF to DEN. 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. 364 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 5878

For a booking, read OO 5878 as 78.1% on time with 0.27% cancelled over 364 flights. Those are rates from the past twelve months, not a forecast for any particular day.
