Time lost at the gate mostly stays lost. Of 68 departures that left 15 minutes late or more, only 4 made it up before arrival. In the other direction, 38 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.

Connections and routes
What a delay on this flight costs
14.1% 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 SLC to PDX (50), but none flew often enough under OO 3497 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to PSP to SFO only.
One caution: this is a thin sample. 271 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 3497
For a booking, OO 3497 is a flight to put a long connection behind. 14.1% 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.
