These figures cover 741 flights between September 2025 and August 2026. The median arrival is 11 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Best ways to make this trip
The most reliable ways to fly Santa Rosa to Burbank
Every airline on this route and on the routes between nearby airports, ranked by how often a scheduled flight actually operated and arrived on time. 2 of the top 3 use a different airport at one end.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. STS → LAXSanta Rosa to Los Angeles | SkyWest Airlines | 83.3% | 85.8% | 2.91% | 11am–2pm, Sat (route) | — |

| 3. STS → BURSanta Rosa to Burbank | SkyWest Airlines | 79.8% | 82.1% | 2.77% | 8am–11am, Tue | — |
Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.
Departure window
The best time of day to leave
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 25 points, against half a point between the best and worst carrier.

- 8am–11am78 flights93.5%
- 11am–2pm79 flights93.7%
- 2pm–5pm195 flights68.6%
- 5pm–8pm103 flights82.4%
- 8pm–5am35 flights71.4%
Scale runs 60% to 100%.
The best window here is not the first bank but the 11am–2pm slot at 93.7% on time, ahead of 2pm–5pm at 68.6%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 5am–8am window is the busiest, with 251 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 31 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
January is the weak month at 58.8% on time, against 90.0% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. August was the busiest month here, with 93 flights.
Across the week, Tuesday is the strongest day at 91.1% on time and Sunday the weakest at 72.5%, a spread of 19 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 48% of the 7,107 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 30%Carrier
- 13%Extreme weather
- 9%National Airspace System
Extreme weather accounts for 13% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.1 times the usual weather exposure. The split is drawn from 7,107 reported delay minutes.
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,107 reported delay minutes here, that single category outweighs weather by 4 to one.
Cancellations sit at 2.29% against a national 1.89%, which is ordinary. Diversions add another 0.40%.
Connections and stage length
What a delay here actually costs
5.3% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
At 387 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 11am–2pm window matters as much as it does.
The return leg runs 84.1% on time across 741 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 741 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 this route
Put together: treat all of this as provisional. 741 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 82.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 721 completed flights over 12 months sit behind that.
Common questions
STS to BUR questions
How often is STS to BUR delayed?
About one flight in six arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 17.8% of the 741 flights in this analysis, against 22.7% nationally. Delayed flights are late by about an hour on average.
How reliable is STS to BUR compared with the rest of the country?
82.2% of flights arrive on time here against a national 77.3%, a difference of 5 points in its favour. That is worth a B on this site's grading scale.
What time of day has the fewest delays on STS to BUR?
The 11am–2pm departure window is the strongest at 93.7% on time. The 2pm–5pm window is the weakest at 68.6%, 25 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are January delays on STS to BUR?
January is the weakest month at 58.8% on time, compared with 90.0% in September. Across the year that is 31 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
