Time lost at the gate mostly stays lost. Of 92 departures that left 15 minutes late or more, only 9 made it up before arrival. In the other direction, 70 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 SFO.

Delay causes
Why OO 5899 runs late
National Airspace System accounts for 67% of the 6,997 delay minutes carriers reported here, and the remaining four split what is left.
- 67%National Airspace System
- 20%Carrier
- 11%Late-arriving aircraft
- 2%Extreme weather
67% 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 4,679 minutes out of 6,997, against a national NAS share of 21%. The split is drawn from 6,997 delay minutes reported on OO 5899.
Cancellations sit at 1.50% against a national 1.89%, which is ordinary. Diversions add another 0.30%.
Connections and routes
What a delay on this flight costs
9.8% 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 ORD to SDF (31), but none flew often enough under OO 5899 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RNO to SFO only.
One caution: this is a thin sample. 333 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.
