Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with SkyWest Airlines.

SkyWest on BUR to PHX lands a B, 2 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about 2.7 hours on average. That is a workable record, not a spotless one. That rests on 525 flights, with a median arrival 10 minutes early.

The US average over the same twelve months is 77.6%, so there is little to separate SkyWest on BUR to PHX from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on BUR to PHX, 3,116 flights

These figures cover 525 flights between July 2025 and June 2026. Beyond the headline rate, 9.9% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Carrier by carrier

SkyWest against every carrier on BUR to PHX

SkyWest flew 525 of the 3,116 flights on BUR to PHX, about 17% of it. Its 79.5% on time is 4 points worse than the route as a whole, which runs 83.6%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from Southwest at 85.4% to American at 76.1%. Two 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 22 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–8am—
8am–11am208 flights86.9%
11am–2pm70 flights65.2%
2pm–5pm34 flights76.5%
5pm–8pm213 flights77.3%
8pm–5am—

Scale runs 55% to 90%. 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 65.2% on time against 86.9% for 8am–11am. 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 5pm–8pm window is the busiest, with 213 flights scheduled in it.

Across the year

SkyWest on BUR to PHX through the year

Darker means more delays. Figures are on-time percentages.July best, November worst

Delays peak in November, when the on-time rate falls to 60.0%. July is the strongest month at 95.7%. Moving a flexible trip across that boundary buys 36 points. January was the busiest month here, with 74 flights.

Across the week, Wednesday is the strongest day at 86.2% on time and Sunday the weakest at 70.3%. 16 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 63% of the 17,000 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.

The largest share of delay minutes, 63%, 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 11,000 of the 17,000 delay minutes reported here. The split is drawn from 17,351 reported delay minutes.

Cancellations sit at 1.33% against a national 1.81%, which is ordinary. Diversions add another 0.19%.

Connections and stage length

What a delay here costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.9% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

At 369 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 runs 79.8% on time across 525 flights, within half a point 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. 525 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 PHX

Put together: treat all of this as provisional. 525 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 79.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 517 completed flights over 12 months sit behind that.
