This route lands a B, about a point worse than the national rate of 77.3%. About one flight in four arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 1,042 LAS to FLL flights, with a median arrival 4 minutes early.
Best time to fly LAS to FLL: a 5am–8am departure, ideally on a Tuesday. Flights in that window arrived on time 87.6% of the time and Tuesday flights 80.9%, against 76.4% for the route overall.
The US average over the same twelve months is 77.3%, 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 1,042 flights between September 2025 and August 2026. The median arrival is 4 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.

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 | 82.9% | 83.6% | 0.80% | 5am–8am, Tue (route) | — |
| 2. LAS → FLLLas Vegas to Fort Lauderdale | JetBlue Airways | 76.1% | 77.8% | 2.16% | 5am–8am, Tue | B6 1708 11:13 |
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 16 points, against half a point between the best and worst carrier.

Book the early departure. Flights leaving between 5am–8am arrive on time 87.6% of the time, against 71.8% for the overnight window. That is 16 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 514 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.
Delays peak in March, when the on-time rate falls to 62.6%. August is the strongest month at 90.7%. Moving a flexible trip across that boundary buys 28 points. March was the busiest month here, with 127 flights.
Across the week, Tuesday is the strongest day at 80.9% on time and Sunday the weakest at 67.8%, a spread of 13 points.
Delay causes
Why this route gets delayed
Carrier accounts for 45% of the 17,000 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Carrier
- 35%Late-arriving aircraft
- 19%National Airspace System
- 1%Extreme weather
35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 17,000 reported delay minutes here, that single category outweighs weather by 35 to one. The split is drawn from 16,644 reported delay minutes.
The largest share of delay minutes, 45%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 7,493 of the 17,000 delay minutes reported here.
Cancellations sit at 2.21% against a national 1.89%, which is ordinary. Diversions add another 0.58%.
Connections and stage length
What a delay here actually costs
7.8% of arrivals land an hour or more late, close to the national 8.3%, so 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 75.8% on time across 1,042 flights, within half a point 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. 1,042 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. 1,042 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 76.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 1,013 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 23.6% of the 1,042 flights in this analysis, against 22.7% 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?
76.4% of flights arrive on time here against a national 77.3%, a difference of about a point against it. That is worth a B 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 87.6% on time. The 8pm–5am window is the weakest at 71.8%, 16 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 90.7% in August. 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.
