Every carrier on FLL to LAX, 2,275 flights

These figures cover 163 flights between July 2025 and June 2026. Beyond the headline rate, 11.9% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Carrier by carrier

Spirit against every carrier on FLL to LAX

Spirit flew 163 of the 2,275 flights on FLL to LAX, about 7% of it. Its 61.2% on time is 15 points worse than the route as a whole, which runs 76.5%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Delta at 85.8% to Spirit at 61.2%. 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 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 163 flights.

There are not enough flights in each departure window to split Spirit's FLL to LAX record by time of day without the percentages moving on noise. The headline rate of 61.2% is the reliable figure here.

Across the year

Spirit on FLL to LAX through the year

Jul–Sep 202526 flights—
Oct–Dec 202552 flights76.5%
Jan–Mar 202671 flights44.3%
Apr–Jun 202614 flights—

Scale runs 35% to 80%. 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 61.2% on time across 163 flights.

Split by quarter, Spirit on FLL to LAX logged 26 flights in Jul–Sep 2025, 52 flights in Oct–Dec 2025, 71 flights in Jan–Mar 2026 and 14 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 61.2% annual figure is the one to use.

Delay causes

Why Spirit runs late on this route

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 3,751 reported delay minutes.

The largest share of delay minutes, 37%, 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 1,392 of the 3,751 delay minutes reported here. The split is drawn from 3,751 reported delay minutes.

Cancellations sit at 1.84% 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. 11.9% 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 2,343 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 56.4% on time across 164 flights, 5 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 5 points of difference.

One caution: this is a thin sample. 163 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 FLL to LAX

Put together: treat all of this as provisional. 163 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 61.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 160 completed flights over 12 months sit behind that.
