Spirit on LAS to RNO earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 541 flights, with a median arrival 11 minutes early.
Set against the rest of the country, Spirit's LAS to RNO record is 10 points better than the US average of 77.6%. That gap is worth roughly 102 fewer late arrivals for every thousand flights.

Every carrier on LAS to RNO, 4,020 flights
These figures cover 541 flights between July 2025 and June 2026. The median arrival is 11 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
Spirit against every carrier on LAS to RNO
Spirit flew 541 of the 4,020 flights on LAS to RNO, about 13% of it. Its 87.8% on time is 8 points better than the route as a whole, which runs 79.7%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Spirit at 87.8% to Frontier at 77.6%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window
When Spirit runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 10 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am77 flights92.2%
- 8am–11am157 flights92.3%
- 11am–2pm70 flights82.6%
- 2pm–5pm13 flights—
- 5pm–8pm118 flights88.5%
- 8pm–5am106 flights81.9%
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 92.3% of the time, against 81.9% for the overnight window. That is 10 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 157 flights scheduled in it.
Across the year
Spirit on LAS to RNO through the year
Delays peak in November, when the on-time rate falls to 78.8%. January is the strongest month at 96.3%. Moving a flexible trip across that boundary buys 18 points. August was the busiest month here, with 63 flights.
Across the week, Wednesday is the strongest day at 98.5% on time and Friday the weakest at 81.7%. 17 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Spirit runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 47% of the 5,131 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.
- 47%Late-arriving aircraft
- 29%National Airspace System
- 24%Carrier
47% 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 5,131 reported delay minutes here, that single category outweighs weather by 47 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 5,131 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 92.3% on time here.
Cancellations sit at 1.66% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
5.5% 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 a little over an hour, which a normal layover absorbs.
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 runs 87.4% on time across 542 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 541 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 Spirit on LAS to RNO
Put together: treat all of this as provisional. 541 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 87.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 532 completed flights over 12 months sit behind that.
