Spirit on LAS to BUR 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 10 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 909 flights, with a median arrival 15 minutes early.
Set against the rest of the country, Spirit's LAS to BUR record is 10 points better than the US average of 77.6%. That gap is worth roughly 100 fewer late arrivals for every thousand flights.

These figures cover 909 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
Spirit against every carrier on LAS to BUR
Spirit flew 909 of the 4,185 flights on LAS to BUR, about 22% of it. Its 87.6% on time is 8 points better than the route as a whole, which runs 79.8%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Spirit at 87.6% to Southwest at 77.6%. 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 Spirit runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 15 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–8am156 flights94.0%
- 8am–11am186 flights91.7%
- 11am–2pm182 flights87.1%
- 2pm–5pm222 flights85.8%
- 5pm–8pm115 flights79.3%
- 8pm–5am48 flights81.2%
Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 94.0% of the time, against 79.3% for the evening window. That is 15 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 2pm–5pm window is the busiest, with 222 flights scheduled in it.
Across the year
Spirit on LAS to BUR through the year
August is the worst month at 81.0% on time, 13 points below February, the best at 94.4%. 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. August was the busiest month here, with 127 flights.
Across the week, Tuesday is the strongest day at 92.9% on time and Friday the weakest at 80.6%. 12 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Spirit runs late on this route
One category carries most of the weight here. National Airspace System accounts for 51% of the 8,238 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.
- 51%National Airspace System
- 32%Late-arriving aircraft
- 14%Carrier
- 4%Extreme weather
51% 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 4,163 minutes out of 8,238, against a national NAS share of 21%. The split is drawn from 8,238 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 94.0% on time here.
Cancellations sit at 2.31% against a national 1.81%, which is ordinary. Diversions add another 0.22%.
Connections and stage length
What a delay here costs
5.5% 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 a little over an hour, which a normal layover absorbs.
At 223 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 is a different operation and performs like one: it runs 82.6% on time across 910 flights, 5 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 5 points of difference.
One caution: this is a thin sample. 909 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 Spirit on LAS to BUR
Put together: treat all of this as provisional. 909 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 87.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 886 completed flights over 12 months sit behind that.
