These figures cover 264 flights between July 2025 and June 2026. Beyond the headline rate, 12.8% 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 RNO to LAS
Frontier flew 264 of the 4,019 flights on RNO to LAS, about 7% of it. Its 70.2% on time is 12 points worse than the route as a whole, which runs 82.1%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Spirit at 87.4% to Frontier at 70.2%.
The two carriers here are closely matched: 5 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 matters more here than the choice of carrier. The gap between the best and worst window is 13 points, against 5 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am—
- 8am–11am3 flights—
- 11am–2pm39 flights73.7%
- 2pm–5pm101 flights75.5%
- 5pm–8pm77 flights62.7%
- 8pm–5am44 flights65.9%
Scale runs 55% to 80%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 62.7% on time, against 75.5% for the 2pm–5pm slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 2pm–5pm window is the busiest, with 101 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 70.2% on time across 264 flights.
Frontier on RNO to LAS did not run the same all year. Its best quarter was Jan–Mar 2026 at 77.3% on time and its weakest Jul–Sep 2025 at 62.0%, a swing of 15 points on roughly 66 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.
Across the week, Friday is the strongest day at 75.4% on time and Monday the weakest at 57.4%. 18 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Frontier runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 80% of the 7,570 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.
- 80%Late-arriving aircraft
- 12%National Airspace System
- 8%Carrier
- 0%Extreme weather
80% 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 7,570 reported delay minutes here, that single category outweighs weather by 80 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 7,570 reported delay minutes.
Cancellations sit at 2.27% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
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. 12.8% 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 345 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 2pm–5pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 77.6% on time across 264 flights, 7 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 7 points of difference.
One caution: this is a thin sample. 264 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 RNO to LAS
Put together: treat all of this as provisional. 264 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 70.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 258 completed flights over 12 months sit behind that.
