| 17 July 2026 | 3 hours 25 minutes | National Airspace System |
| 24 August 2026 | 3 hours 1 minute | Late-arriving aircraft |

Delay causes
Why OO 3017 runs late
Late-arriving aircraft accounts for 56% of the 5,011 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Late-arriving aircraft
- 25%National Airspace System
- 16%Carrier
- 3%Extreme weather
56% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,011 reported delay minutes here, that single category outweighs weather by 20 to one. The split is drawn from 5,011 delay minutes reported on OO 3017.
Cancellations are rare at 0.39%, 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
13.6% 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 626 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on three other city pairs in the data, including SJC to PDX (33), SAN to DEN (27) and DEN to SAN (27), but none flew often enough under OO 3017 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SAN to SLC only.
One caution: this is a thin sample. 259 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 3017
For a booking, OO 3017 is a flight to put a long connection behind. 13.6% 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.
