This route sits in the middle of the pack with a C. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 1,048 LAS to FLL flights, with a median arrival 3 minutes early.
Best time to fly LAS to FLL: a 5am–8am departure, ideally on a Saturday. Flights in that window arrived on time 88.9% of the time and Saturday flights 78.5%, against 74.8% for the route overall.
The US average over the same twelve months is 77.6%, so there is little to separate this route from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 1,048 flights between July 2025 and June 2026. Beyond the headline rate, 8.2% 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.

Best ways to make this trip
The most reliable ways to fly Las Vegas to Fort Lauderdale
Every airline on this route and on the routes between nearby airports, ranked by how often a scheduled flight actually operated and arrived on time. 1 of the top 2 use a different airport at one end.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. LAS → MIALas Vegas to Miami | American Airlines | 83.4% | 84.1% | 0.86% | 5am–8am, Tue (route) | — |
| 2. LAS → FLLLas Vegas to Fort Lauderdale | JetBlue Airways | 75.1% | 76.7% | 2.05% | 5am–8am, Tue | B6 1708 12:10 |
Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.
Departure window
The best time of day to leave
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 18 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am141 flights88.9%
- 8am–11am93 flights81.1%
- 11am–2pm240 flights74.2%
- 2pm–5pm3 flights—
- 5pm–8pm—
- 8pm–5am571 flights70.8%
Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 88.9% of the time, against 70.8% for the overnight window. That is 18 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 571 flights scheduled in it.
Across the year
When delays peak on this route
This route's year swings by 28 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
November is the best month on the calendar at 90.6% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. March was the busiest month here, with 127 flights.
Across the week, Saturday is the strongest day at 78.5% on time and Sunday the weakest at 67.5%. 11 points is a smaller lever than departure hour, but it is free.
Delay causes
Why this route gets delayed
One category carries most of the weight here. Carrier accounts for 47% of the 18,000 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.
- 47%Carrier
- 34%Late-arriving aircraft
- 19%National Airspace System
- 1%Extreme weather
The largest share of delay minutes, 47%, 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 8,336 of the 18,000 delay minutes reported here. The split is drawn from 17,732 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 88.9% on time here.
Cancellations sit at 2.00% against a national 1.81%, which is ordinary. Diversions add another 0.19%.
Connections and stage length
What a delay here actually costs
8.2% 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 last a little over an hour, which a normal layover absorbs.
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 77.4% on time across 1,046 flights, within 3 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. 1,048 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 this route
Put together: treat all of this as provisional. 1,048 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 74.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 1,025 completed flights over 12 months sit behind that.
Common questions
LAS to FLL questions
How often is LAS to FLL delayed?
About one flight in four arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 25.2% of the 1,048 flights in this analysis, against 22.4% nationally. Delayed flights are late by a little over an hour on average.
How reliable is LAS to FLL compared with the rest of the country?
74.8% of flights arrive on time here against a national 77.6%, a difference of 3 points against it. That is worth a C on this site's grading scale.
What time of day has the fewest delays on LAS to FLL?
The 5am–8am departure window is the strongest at 88.9% on time. The 8pm–5am window is the weakest at 70.8%, 18 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 LAS to FLL?
March is the weakest month at 62.6% on time, compared with 90.6% in November. Across the year that is 28 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
