These figures cover 113 flights between July 2025 and June 2026. Beyond the headline rate, 10.7% 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

Frontier against every carrier on BUR to LAS

Frontier flew 113 of the 4,203 flights on BUR to LAS, about 3% of it. Its 71.4% on time is 9 points worse than the route as a whole, which runs 80.8%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Spirit at 82.6% to Frontier at 71.4%.

The two carriers here are closely matched: 2 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.

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 BUR to LAS record by time of day without the percentages moving on noise. The headline rate of 71.4% is the reliable figure here.

Across the year

Frontier on BUR to LAS through the year

Oct–Dec 202512 flights—
Jan–Mar 202646 flights69.6%
Apr–Jun 202655 flights70.4%

Scale runs 60% to 75%. 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 71.4% on time across 113 flights.

Split by quarter, Frontier on BUR to LAS 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 71.4% 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 75% of the 2,768 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.

75% 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 2,768 reported delay minutes here, that single category outweighs weather by 75 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 2,768 reported delay minutes.

The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 90.6% on time here.

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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.7% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

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 8am–11am window matters as much as it does.

The return leg is a different operation and performs like one: it runs 81.2% on time across 113 flights, 10 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 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 BUR to LAS

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 71.4% 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.
