This route lands a B, 3 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That rests on 4,116 BUR to LAS flights, of which Spirit Airlines flew 670 at 84.0% on time.
Best time to fly BUR to LAS: a 5am–8am departure, ideally on a Saturday. Flights in that window arrived on time 93.7% of the time and Saturday flights 87.8%, against 80.4% for the route overall.
The US average over the same twelve months is 77.3%, so there is little to separate this route from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 4,116 flights between September 2025 and August 2026. The median arrival is 8 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
Which airline is most reliable on BUR to LAS
The two carriers here are closely matched: 4 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|

| Frontier Airlinesthin sample | 206 | 73.3% | 104 min | 1.94% | C |
Spirit Airlines cancels 3.1% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Best ways to make this trip
The most reliable ways to fly Burbank to Las Vegas
Every airline on this route and on the routes between nearby airports, ranked by how often a scheduled flight actually operated and arrived on time. 4 of the top 5 use a different airport at one end.

Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.
Departure window
The best time of day to leave
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 21 points, against 4 points between the best and worst carrier.

- 8am–11am963 flights89.8%
- 11am–2pm765 flights78.9%

Scale runs 65% to 100%.
Book the early departure. Flights leaving between 5am–8am arrive on time 93.7% of the time, against 72.6% for the overnight window. That is 21 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 963 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 14 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
August is the worst month at 73.0% on time, 14 points below February, the best at 86.8%. 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. March was the busiest month here, with 377 flights.
Across the week, Saturday is the strongest day at 87.8% on time and Friday the weakest at 70.2%, a spread of 18 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 54% of the 49,000 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Late-arriving aircraft
- 32%National Airspace System
- 12%Carrier
- 2%Extreme weather
- 0%Security
54% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 49,000 reported delay minutes here, that single category outweighs weather by 28 to one. The split is drawn from 49,379 reported delay minutes.
32% 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 16,000 minutes out of 49,000, against a national NAS share of 21%.
Cancellations sit at 1.70% against a national 1.89%, which is ordinary. Diversions add another 0.07%.
Connections and stage length
What a delay here actually costs
6.6% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 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 runs 78.9% on time across 4,075 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
The sample behind these figures is 4,116 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this
Booking this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. February runs 86.8% on time and August 73.0%, a swing of 14 points. If the dates move at all, move them out of August before you think about anything else. 4,043 completed flights over 12 months sit behind that.
Common questions
BUR to LAS questions
How often is BUR to LAS delayed?
About one flight in five arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 19.6% of the 4,116 flights in this analysis, against 22.7% nationally. Delayed flights are late by about an hour on average.
Which airline is most reliable on BUR to LAS?
Spirit Airlines leads at 84.0% on time across 670 flights. Southwest Airlines is at the other end on 80.1%, a gap of 4 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on BUR to LAS?
The 5am–8am departure window is the strongest at 93.7% on time. The 8pm–5am window is the weakest at 72.6%, 21 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are August delays on BUR to LAS?
August is the weakest month at 73.0% on time, compared with 86.8% in February. Across the year that is 14 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
