When something does go wrong the average delay runs about 50 minutes. That rests on 2,137 SJC to BUR flights, with a median arrival 9 minutes early.

These figures cover 2,137 flights between September 2025 and August 2026. The median arrival is 9 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.

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 28 points, against half a point between the best and worst carrier.
- 5am–8am280 flights94.8%
- 8am–11am495 flights94.0%
- 11am–2pm378 flights87.1%

- 5pm–8pm349 flights80.4%
- 8pm–5am245 flights66.8%
Scale runs 60% to 100%.
Book the early departure. Flights leaving between 5am–8am arrive on time 94.8% of the time, against 66.8% for the overnight window. That is 28 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 495 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 16 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.
August is the worst month at 77.5% on time, 16 points below January, the best at 93.6%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. October was the busiest month here, with 211 flights.
Across the week, Tuesday is the strongest day at 92.9% on time and Sunday the weakest at 77.4%, a spread of 16 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 65% of the 16,000 delay minutes carriers reported here, and the remaining four split what is left.
- 65%Late-arriving aircraft
- 21%Carrier
- 12%National Airspace System
- 1%Extreme weather
65% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 16,000 reported delay minutes here, that single category outweighs weather by 45 to one. The split is drawn from 16,188 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 94.8% on time here.
Cancellations sit at 1.26% against a national 1.89%, which is ordinary. Diversions add another 0.33%.
Connections and stage length
What a delay here actually costs
Badly late arrivals are rare here: only 4.2% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
At 296 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 runs 86.3% on time across 2,133 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.
The sample behind these figures is 2,137 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this
Booking this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. January runs 93.6% on time and August 77.5%, a swing of 16 points. If the dates move at all, move them out of August before you think about anything else. 2,103 completed flights over 12 months sit behind that.

The 5am–8am departure window is the strongest at 94.8% on time. The 8pm–5am window is the weakest at 66.8%, 28 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.
