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

Frontier on LAS to BUR lands a B+, 4 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 close to two hours on average. That is a workable record, not a spotless one. That rests on 113 flights. The strongest carrier on the route with a full sample, Spirit Airlines, flew 909 at 87.6% on time.

The US average over the same twelve months is 77.6%, so there is little to separate Frontier on LAS 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 LAS to BUR, 4,185 flights

These figures cover 113 flights between July 2025 and June 2026. Beyond the headline rate, 8.0% 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

Frontier against every carrier on LAS to BUR

Frontier flew 113 of the 4,185 flights on LAS to BUR, about 3% of it. Its 81.2% on time is about level with the route as a whole at 79.8%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Spirit at 87.6% to Southwest at 77.6%.

The choice of carrier is not cosmetic here. Spirit Airlines arrives on time 87.6% of the time; Southwest Airlines manages 77.6%. Sample sizes sit next to every figure, because a two-point gap across 3,163 flights means less than a ten-point one.

On-time performance by carrier on LAS to BUR
Airline	Flights	On time	Avg delay	Cancelled	Grade
Spirit Airlines	909	87.6%	75 min	2.31%	A
Frontier Airlines (this page)thin sample	113	81.2%	111 min	0.88%	B+
Southwest Airlines	3,163	77.6%	54 min	1.07%	B

Spirit leads Southwest by 10 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Departure window

When Frontier runs best on this route

Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 113 flights.

There are not enough flights in each departure window to split Frontier's LAS to BUR record by time of day without the percentages moving on noise. The headline rate of 81.2% is the reliable figure here.

Across the year

Frontier on LAS to BUR through the year

Oct–Dec 202512 flights—
Jan–Mar 202646 flights84.8%
Apr–Jun 202655 flights77.8%

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 81.2% on time across 113 flights.

Split by quarter, Frontier on LAS to BUR logged 12 flights in Oct–Dec 2025, 46 flights in Jan–Mar 2026 and 55 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 81.2% annual figure is the one to use.

Delay causes

Why Frontier runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 59% of the 2,331 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.

National Airspace System
6%

Extreme weather accounts for 23% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 3.7 times the usual weather exposure. The split is drawn from 2,331 reported delay minutes.

59% 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 2,331 reported delay minutes here, that single category outweighs weather by 3 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.

Cancellations are rare at 0.88%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and stage length

What a delay here costs

8.0% 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 close to two hours, 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 5pm–8pm window matters as much as it does.

The return leg is a different operation and performs like one: it runs 71.4% on time across 113 flights, 10 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 10 points of difference.

One caution: this is a thin sample. 113 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 Frontier on LAS to BUR

Put together: treat all of this as provisional. 113 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 81.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 112 completed flights over 12 months sit behind that.
