Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with SkyWest Airlines.
SkyWest on SFO to BUR lands a B, 2 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 924 flights. The strongest carrier on the route with a full sample, United Airlines, flew 1,663 at 80.2% on time.
The US average over the same twelve months is 77.3%, so there is little to separate SkyWest on SFO to BUR from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
SkyWest against every carrier on SFO to BUR
SkyWest flew 924 of the 3,101 flights on SFO to BUR, about 30% of it. Its 79.2% on time is 4 points better than the route as a whole, which runs 74.9%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from United at 80.2% to Southwest at 49.7%.
The choice of carrier is not cosmetic here. United Airlines arrives on time 80.2% of the time; Southwest Airlines manages 49.7%. Sample sizes sit next to every figure, because a two-point gap across 514 flights means less than a ten-point one.

Delay causes
Why SkyWest runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 14,000 reported delay minutes.
- 33%Late-arriving aircraft
- 32%National Airspace System
- 25%Carrier
- 10%Extreme weather
32% 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 4,521 minutes out of 14,000, against a national NAS share of 21%. The split is drawn from 14,035 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 86.3% on time here.
Cancellations sit at 2.06% against a national 1.89%, which is ordinary. Diversions add another 0.43%.
Connections and stage length
What a delay here costs
9.7% 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 326 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 8am–11am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 72.7% on time across 928 flights, 7 points below 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 7 points of difference.
One caution: this is a thin sample. 924 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 SFO to BUR
Put together: treat all of this as provisional. 924 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 79.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 901 completed flights over 12 months sit behind that.
