Carrier by carrier
Spirit against every carrier on LAS to FLL
Spirit flew 250 of the 1,048 flights on LAS to FLL, about 24% of it. Its 69.0% on time is 6 points worse than the route as a whole, which runs 74.8%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from Southwest at 78.6% to Delta at 66.7%. Two 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 is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 250 flights.
The overnight block holds up unusually well at 68.9% on time across 246 flights. Red-eyes fly into empty airspace and empty gates, and they are the first rotation of the aircraft's day rather than the last. The 8pm–5am window is the busiest, with 246 flights scheduled in it.

Scale runs 55% to 85%. Rows with fewer than 30 flights show a dash.
Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 69.0% on time across 250 flights.
Spirit on LAS to FLL did not run the same all year. Its best quarter was Oct–Dec 2025 at 78.3% on time and its weakest Jan–Mar 2026 at 63.6%, a swing of 15 points on roughly 83 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, Saturday is the strongest day at 80.0% on time and Monday the weakest at 57.1%. 23 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 68% of the 7,487 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.
- 68%Carrier
- 17%National Airspace System
- 14%Late-arriving aircraft
- 1%Extreme weather
The largest share of delay minutes, 68%, 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 5,093 of the 7,487 delay minutes reported here. The split is drawn from 7,487 reported delay minutes.
Cancellations sit at 2.00% 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. 12.2% 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 2,173 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
The return leg runs 71.1% on time across 248 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. 250 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 FLL
Put together: treat all of this as provisional. 250 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 69.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 245 completed flights over 12 months sit behind that.
