Share of 639 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 201 departures that left 15 minutes late or more, only 12 made it up before arrival. In the other direction, 65 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 SkyWest runs late on this route
National Airspace System accounts for 55% of the 20,000 delay minutes carriers reported here, and the remaining four split what is left.
- 55%National Airspace System
- 22%Carrier
- 16%Late-arriving aircraft
- 7%Extreme weather
55% 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 11,000 minutes out of 20,000, against a national NAS share of 21%. The split is drawn from 19,500 reported delay minutes.
Cancellations sit at 1.37% against a national 1.89%, which is ordinary. Diversions add another 1.07%.
Connections and stage length
What a delay here costs
18.8% 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.
At 462 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5am–8am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 68.8% on time across 654 flights, 9 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 9 points of difference.
One caution: this is a thin sample. 655 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 SkyWest on RDM to SFO
Put together: treat all of this as provisional. 655 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 60.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 639 completed flights over 12 months sit behind that.
