Best ways to make this trip
The most reliable ways to fly Los Angeles 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. 2 of the top 4 use a different airport at one end.

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 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 2,331 flights.
- 5am–8am90 flights77.0%
- 8am–11am502 flights76.4%
- 11am–2pm437 flights68.9%
- 2pm–5pm362 flights77.0%
- 5pm–8pm—
- 8pm–5am940 flights71.8%
Scale runs 60% to 80%. Rows with fewer than 30 flights show a dash.
The weak window here is the middle of the day, not the evening: 11am–2pm runs 68.9% on time against 77.0% for 5am–8am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 8pm–5am window is the busiest, with 940 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 48 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.
September is the best month on the calendar at 94.3% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. December was the busiest month here, with 238 flights.
Across the week, Tuesday is the strongest day at 77.9% on time and Thursday the weakest at 69.2%, a spread of 9 points.
Delay causes
Why this route gets delayed
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 36,000 reported delay minutes.
- 40%Late-arriving aircraft
- 34%Carrier
- 25%National Airspace System
- 0%Security
40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 36,000 reported delay minutes here, that single category outweighs weather by 40 to one. The split is drawn from 35,747 reported delay minutes.
The largest share of delay minutes, 34%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 12,000 of the 36,000 delay minutes reported here.
Cancellations sit at 1.46% against a national 1.89%, which is ordinary. Diversions add another 0.26%.
Connections and stage length
What a delay here actually costs
8.3% 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 about an hour, which a normal layover absorbs.
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 runs 75.8% on time across 2,333 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.
The sample behind these figures is 2,331 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this
Booking this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 94.3% on time and March 46.3%, a swing of 48 points. If the dates move at all, move them out of March before you think about anything else. 2,291 completed flights over 12 months sit behind that.
Common questions
LAX to FLL questions
How often is LAX 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 26.8% of the 2,331 flights in this analysis, against 22.7% nationally. Delayed flights are late by about an hour on average.
Which airline is most reliable on LAX to FLL?
JetBlue Airways leads at 75.3% on time across 1,810 flights. Delta Air Lines is at the other end on 71.2%, a gap of 4 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on LAX to FLL?
The 5am–8am departure window is the strongest at 77.0% on time. The 11am–2pm window is the weakest at 68.9%, 8 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 LAX to FLL?
March is the weakest month at 46.3% on time, compared with 94.3% in September. Across the year that is 48 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
