Departure window
When SkyWest runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 57 points, against half a point between the best and worst carrier.
- 5am–8am129 flights92.2%
- 8am–11am198 flights67.9%
- 11am–2pm156 flights34.8%
- 2pm–5pm323 flights55.4%
- 5pm–8pm191 flights62.3%
- 8pm–5am40 flights62.2%
Scale runs 25% to 100%.
The weak window here is the middle of the day, not the evening: 11am–2pm runs 34.8% on time against 92.2% for 5am–8am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 2pm–5pm window is the busiest, with 323 flights scheduled in it.

Time lost at the gate mostly stays lost. Of 305 departures that left 15 minutes late or more, only 30 made it up before arrival. In the other direction, 122 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.
The worst days
Worst days for SkyWest on RNO to SFO
The latest arrival of the period was on 5 May 2026, 18 hours 5 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). Three of the five worst days fell in May 2026.
| Date | Arrived late by | Largest filed cause |

Delay causes
Why SkyWest runs late on this route
National Airspace System accounts for 56% of the 27,000 delay minutes carriers reported here, and the remaining four split what is left.
- 56%National Airspace System
- 21%Carrier
- 19%Late-arriving aircraft
- 4%Extreme weather
56% 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 15,000 minutes out of 27,000, against a national NAS share of 21%. The split is drawn from 26,820 reported delay minutes.
Cancellations sit at 2.12% against a national 1.89%, which is ordinary. Diversions add another 0.19%.
Connections and stage length
What a delay here costs
12.1% 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.
At 192 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 72.5% on time across 1,035 flights, 12 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 12 points of difference.
One caution: this is a thin sample. 1,037 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 RNO to SFO
Put together: treat all of this as provisional. 1,037 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 60.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 1,013 completed flights over 12 months sit behind that.
