Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Spirit Airlines.
Spirit on LAS to LAX 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 about an hour. That rests on 646 flights. The strongest carrier on the route with a full sample, United Airlines, flew 1,574 at 86.2% on time.
Set against the rest of the country, Spirit's LAS to LAX record is 10 points better than the US average of 77.6%. That gap is worth roughly 97 fewer late arrivals for every thousand flights.

Every carrier on LAS to LAX, 8,325 flights
These figures cover 646 flights between July 2025 and June 2026. The median arrival is 13 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 LAX
Spirit flew 646 of the 8,325 flights on LAS to LAX, about 8% of it. Its 87.3% on time is 9 points better than the route as a whole, which runs 78.8%. Ranked by on-time rate it is first of eight carriers on the route, where the range runs from Spirit at 87.3% to Southwest at 68.2%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. United Airlines arrives on time 86.2% of the time; Southwest Airlines manages 68.2%. Sample sizes sit next to every figure, because a two-point gap across 2,386 flights means less than a ten-point one.

| Southwest Airlines | 2,386 | 68.2% | 47 min | 0.38% | C+ |
The spread between United and Southwest is 18 points, wide enough that it should decide the booking. On a hundred trips that is 18 more arrivals inside the on-time window.
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 12 points, against 18 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am121 flights89.3%
- 8am–11am112 flights88.1%
- 11am–2pm61 flights93.4%
- 2pm–5pm139 flights89.8%
- 5pm–8pm109 flights81.7%
- 8pm–5am104 flights83.5%
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 93.4% on time, ahead of 5pm–8pm at 81.7%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 2pm–5pm window is the busiest, with 139 flights scheduled in it.
Across the year
Spirit on LAS to LAX through the year
December is the weak month at 84.4% on time, against 91.3% in August. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. August was the busiest month here, with 92 flights.
Across the week, Tuesday is the strongest day at 93.2% on time and Friday the weakest at 77.9%. 15 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. Carrier accounts for 44% of the 5,051 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.
- 44%Carrier
- 29%National Airspace System
- 22%Late-arriving aircraft
- 5%Extreme weather
The largest share of delay minutes, 44%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,208 of the 5,051 delay minutes reported here. The split is drawn from 5,051 reported delay minutes.
Cancellations sit at 0.93% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 4.1% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
At 236 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 11am–2pm window matters as much as it does.
The return leg runs 84.9% on time across 640 flights, within 2 points 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. 646 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 LAX
Put together: treat all of this as provisional. 646 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 87.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 640 completed flights over 12 months sit behind that.
