Spirit Airlines at Las Vegas lands a B, 5 points better than the national rate of 77.6%. About one flight in six arrive 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 8,396 flights, of which Delta Air Lines flew 15,755 at 85.6% on time.
Measured against the airport rather than the country, Spirit Airlines runs 5 points ahead of the 77.9% weighted average across all carriers at LAS. That is the comparison worth making: every operator here works the same runways, the same airspace and the same weather.

#3
Of 11 carriers clearing the floor at LAS
These figures cover 8,396 flights between July 2025 and June 2026. The median arrival is 9 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.
Against the competition
Every carrier at LAS, ranked
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 85.6% of the time; Hawaiian Airlines manages 69.4%. Sample sizes sit next to every figure, because a two-point gap across 855 flights means less than a ten-point one.

| Hawaiian Airlines | 855 | 69.4% | 86 min | 0.47% | C+ |
The spread between Delta and Hawaiian is 16 points, wide enough that it should decide the booking. On a hundred trips that is 16 more arrivals inside the on-time window.
Route by route
Where Spirit Airlines flies from LAS
Spirit Airlines operates 25 routes out of LAS with enough volume to report. Route records inside one carrier at one airport still spread widely, because a short shuttle and a transcontinental have very different exposure to a late inbound.

Departure window
Best time of day for this operation
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 13 points, against 16 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am752 flights91.8%
- 8am–11am1,821 flights86.3%
- 11am–2pm1,392 flights83.5%
- 2pm–5pm1,080 flights82.1%
- 5pm–8pm960 flights78.9%
- 8pm–5am2,391 flights78.8%
Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 91.8% of the time, against 78.8% for the overnight window. That is 13 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8pm–5am window is the busiest, with 2,391 flights scheduled in it.
Across the year
Seasonal pattern
October is the best month on the calendar at 90.3% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. July was the busiest month here, with 1,476 flights.

The largest share of delay minutes, 40%, 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 43,000 of the 108,000 delay minutes reported here. The split is drawn from 108,472 reported delay minutes.
Cancellations sit at 1.49% against a national 1.81%, which is ordinary. Diversions add another 0.18%.
6.3% 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 are the a little over an hour kind, which a normal layover absorbs.
The sample behind these figures is 8,396 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
Put together: avoid the 8pm–5am departure. It runs 78.8% on time against 91.8% for the 5am–8am slot, and that 13 points is the largest single thing you control here. Delta Air Lines is the strongest operator if the fares are close. 8,256 completed flights over 12 months sit behind that.
Common questions
Spirit Airlines at LAS
How often is Spirit Airlines at LAS delayed?
About one flight in six arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 17.2% of the 8,396 flights in this analysis, against 22.4% nationally. Delayed flights are late by a little over an hour on average.
Which airline is most reliable on Spirit Airlines at LAS?
Delta Air Lines leads at 85.6% on time across 15,755 flights. Hawaiian Airlines is at the other end on 69.4%, a gap of 16 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on Spirit Airlines at LAS?
The 5am–8am departure window is the strongest at 91.8% on time. The 8pm–5am window is the weakest at 78.8%, 13 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are March delays on Spirit Airlines at LAS?
March is the weakest month at 78.4% on time, compared with 90.3% in October. Across the year that is 12 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
