Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Spirit Airlines.
Spirit on BUR to LAS lands a B, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 910 flights, with a median arrival 9 minutes early.
Set against the rest of the country, Spirit's BUR to LAS record is 5 points better than the US average of 77.6%. That gap is worth roughly 50 fewer late arrivals for every thousand flights.

Every carrier on BUR to LAS, 4,203 flights
These figures cover 910 flights between July 2025 and June 2026. The median arrival is 9 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 BUR to LAS
Spirit flew 910 of the 4,203 flights on BUR to LAS, about 22% of it. Its 82.6% on time is 2 points better than the route as a whole, which runs 80.8%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Spirit at 82.6% to Frontier at 71.4%. 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 11 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–8am46 flights87.0%
- 8am–11am212 flights84.7%
- 11am–2pm224 flights84.1%
- 2pm–5pm153 flights83.8%
- 5pm–8pm241 flights78.6%
- 8pm–5am34 flights76.5%
Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 87.0% of the time, against 76.5% for the overnight window. That is 11 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 241 flights scheduled in it.
Across the year
Spirit on BUR to LAS through the year
Delays peak in November, when the on-time rate falls to 76.7%. February is the strongest month at 91.7%. Moving a flexible trip across that boundary buys 15 points. August was the busiest month here, with 127 flights.
Across the week, Tuesday is the strongest day at 89.8% on time and Friday the weakest at 71.9%. 18 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 47% of the 11,000 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.
- 47%National Airspace System
- 41%Late-arriving aircraft
- 9%Carrier
- 3%Extreme weather
- 0%Security
41% 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 11,000 reported delay minutes here, that single category outweighs weather by 14 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 11,107 reported delay minutes.
47% 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 5,196 minutes out of 11,000, against a national NAS share of 21%.
Cancellations run at 2.75%, against 1.81% nationally. That is roughly one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and stage length
What a delay here costs
7.9% 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 87.6% on time across 909 flights, 5 points above 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. 910 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 BUR to LAS
Put together: treat all of this as provisional. 910 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 82.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 885 completed flights over 12 months sit behind that.
