Departure window
When Spirit runs best on this route

There are not enough flights in each departure window to split Spirit's LAS to FLL record by time of day without the percentages moving on noise. The headline rate of 70.6% is the reliable figure here.

Delay causes
Why Spirit runs late on this route
Carrier accounts for 68% of the 6,084 delay minutes carriers reported here, and the remaining four split what is left.
- 68%Carrier
- 16%National Airspace System
- 16%Late-arriving aircraft
- 0%Extreme weather
The largest share of delay minutes, 68%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,124 of the 6,084 delay minutes reported here. The split is drawn from 6,084 reported delay minutes.
Cancellations run at 2.60%, against 1.89% nationally. That is about one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and stage length
What a delay here costs
12.8% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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 is a different operation and performs like one: it runs 66.5% on time across 191 flights, 4 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 4 points of difference.
One caution: this is a thin sample. 192 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. 192 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 70.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 187 completed flights over 12 months sit behind that.
