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

SkyWest on PHX to BUR 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 an hour and a half on average. That is a workable record, not a spotless one. That rests on 525 flights, with a median arrival 7 minutes early.

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

Every carrier on PHX to BUR, 3,127 flights

These figures cover 525 flights between July 2025 and June 2026. Beyond the headline rate, 8.7% 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 PHX to BUR

SkyWest flew 525 of the 3,127 flights on PHX to BUR, about 17% of it. Its 79.8% on time is about level with the route as a whole at 80.2%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from Envoy at 85.2% to American at 67.6%. 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 20 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–8am103 flights93.2%
8am–11am96 flights80.6%
11am–2pm70 flights74.6%
2pm–5pm116 flights73.3%
5pm–8pm140 flights77.2%
8pm–5am—

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 93.2% of the time, against 73.3% for the afternoon window. That is 20 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5pm–8pm window is the busiest, with 140 flights scheduled in it.

Across the year

SkyWest on PHX to BUR through the year

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

Delays peak in March, when the on-time rate falls to 68.3%. July is the strongest month at 93.5%. Moving a flexible trip across that boundary buys 25 points. January was the busiest month here, with 74 flights.

Across the week, Wednesday is the strongest day at 87.7% on time and Saturday the weakest at 73.4%. 14 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 52% of the 8,966 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.

38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 8,966 reported delay minutes here, that single category outweighs weather by 6 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 8,966 reported delay minutes.

The largest share of delay minutes, 52%, 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 4,677 of the 8,966 delay minutes reported here.

Cancellations sit at 0.95% against a national 1.81%, which is ordinary. Diversions add another 0.95%.

Connections and stage length

What a delay here costs

8.7% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.

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 5am–8am window matters as much as it does.

The return leg runs 79.5% 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 PHX to BUR

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 79.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 515 completed flights over 12 months sit behind that.
