Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Frontier Airlines.
Frontier on LAS to RNO lands a B, level with the national rate of 77.6%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 264 flights. The strongest carrier on the route with a full sample, Spirit Airlines, flew 541 at 87.8% on time.
The US average over the same twelve months is 77.6%, so there is little to separate Frontier on LAS to RNO 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 RNO, 4,020 flights
These figures cover 264 flights between July 2025 and June 2026. Beyond the headline rate, 11.2% 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 RNO
Frontier flew 264 of the 4,020 flights on LAS to RNO, about 7% of it. Its 77.6% on time is 2 points worse than the route as a whole, which runs 79.7%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Spirit at 87.8% to Frontier at 77.6%.
The choice of carrier is not cosmetic here. Spirit Airlines arrives on time 87.8% of the time; Southwest Airlines manages 78.5%. Sample sizes sit next to every figure, because a two-point gap across 3,215 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Spirit Airlines | 541 | 87.8% | 79 min | 1.66% | A |
| Southwest Airlines | 3,215 | 78.5% | 52 min | 0.56% | B+ |
| Frontier Airlines (this page)thin sample | 264 | 77.6% | 97 min | 1.89% | B |
Spirit leads Southwest by 9 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 matters more here than the choice of carrier. The gap between the best and worst window is 20 points, against 9 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am3 flights—
- 8am–11am30 flights90.0%
- 11am–2pm100 flights85.6%
- 2pm–5pm29 flights—
- 5pm–8pm100 flights70.0%
- 8pm–5am2 flights—
Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 90.0% of the time, against 70.0% for the evening window. That is 20 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 100 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 77.6% on time across 264 flights.
Frontier on LAS to RNO did not run the same all year. Its best quarter was Jan–Mar 2026 at 84.8% on time and its weakest Oct–Dec 2025 at 69.2%, a swing of 16 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, Thursday is the strongest day at 84.4% on time and Monday the weakest at 63.0%. 21 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 77% of the 5,636 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.
- 77%Late-arriving aircraft
- 16%Carrier
- 4%Extreme weather
- 3%National Airspace System
77% 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 5,636 reported delay minutes here, that single category outweighs weather by 19 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 5,636 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 90.0% on time here.
Cancellations sit at 1.89% 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. 11.2% 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 8am–11am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 70.2% on time across 264 flights, 7 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 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 LAS to RNO
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 77.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 259 completed flights over 12 months sit behind that.
