SkyWest on BUR to SLC earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 15 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 962 flights, with a median arrival 15 minutes early.

Set against the rest of the country, SkyWest's BUR to SLC record is 15 points better than the US average of 77.6%. That gap is worth roughly 147 fewer late arrivals for every thousand flights.

These figures cover 962 flights between July 2025 and June 2026. The median arrival is 15 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.

Carrier by carrier

SkyWest against every carrier on BUR to SLC

SkyWest flew 962 of the 1,484 flights on BUR to SLC, most of the route. Its 92.3% on time is about level with the route as a whole at 90.9%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from SkyWest at 92.3% to Southwest at 76.6%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

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 16 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am34 flights100.0%
  • 8am–11am327 flights94.1%
  • 11am–2pm237 flights84.3%
  • 2pm–5pm129 flights93.8%
  • 5pm–8pm235 flights95.7%
  • 8pm–5am

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

The weak window here is the middle of the day, not the evening: 11am–2pm runs 84.3% on time against 100.0% 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 8am–11am window is the busiest, with 327 flights scheduled in it.

Darker means more delays. Figures are on-time percentages.April best, October worst

April is the best month on the calendar at 97.3% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. October was the busiest month here, with 98 flights.

Across the week, Tuesday is the strongest day at 97.9% on time and Monday the weakest at 87.9%. 10 points is a smaller lever than departure hour, but it is free.

Delay causes

Why SkyWest runs late on this route

One category carries most of the weight here. Carrier accounts for 58% of the 5,078 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

  • Carrier
    58%
  • Extreme weather
    32%
  • National Airspace System
    11%

Extreme weather accounts for 32% 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 5.1 times the usual weather exposure. The split is drawn from 5,078 reported delay minutes.

The largest share of delay minutes, 58%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,925 of the 5,078 delay minutes reported here.

Cancellations are rare at 0.52%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 2.9% land an hour or more behind schedule, against 8.1% 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.

The 574 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The return leg runs 89.5% on time across 962 flights, within 3 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. 962 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 BUR to SLC

Put together: treat all of this as provisional. 962 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 92.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 956 completed flights over 12 months sit behind that.
