This route carries a cancellation problem, not just a delay problem: 4.7% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, about two flights in three arrive on time, worth a D− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 4,714 FLL to LGA flights, of which Delta Air Lines flew 1,590 at 71.8% on time.
Best time to fly FLL to LGA: a 5am–8am departure, ideally on a Wednesday. Flights in that window arrived on time 87.6% of the time and Wednesday flights 75.7%, against 64.8% for the route overall.
Delta Air Lines is the most reliable of the four carriers covered here at 71.8% on time across 1,590 flights.

Carrier by carrier
Which airline is most reliable on FLL to LGA
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 71.8% of the time; American Airlines manages 55.6%. Sample sizes sit next to every figure, because a two-point gap across 595 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Delta Air Lines | 1,590 | 71.8% | 69 min | 3.90% | C− |
| Spirit Airlines | 834 | 63.5% | 79 min | 7.55% | D− |
| JetBlue Airways | 1,695 | 62.1% | 69 min | 4.37% | D− |
| American Airlines | 595 | 55.6% | 100 min | 3.87% | D− |
Spirit Airlines cancels 7.5% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Best ways to make this trip
The most reliable ways to fly Fort Lauderdale to New York
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. 5 of the top 5 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 matters more here than the choice of carrier. The gap between the best and worst window is 34 points, against 16 points between the best and worst carrier.

Scale runs 45% to 95%.
The 5pm–8pm window is where this operation falls apart: 53.1% on time, against 87.6% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5pm–8pm window is the busiest, with 1,211 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 36 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 81.9% 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 496 flights.
Across the week, Wednesday is the strongest day at 75.7% on time and Sunday the weakest at 54.6%, a spread of 21 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 119,000 reported delay minutes.
- 36%Late-arriving aircraft
- 36%National Airspace System
- 24%Carrier
- 3%Extreme weather
- 0%Security
36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 119,000 reported delay minutes here, that single category outweighs weather by 11 to one. The split is drawn from 118,746 reported delay minutes.
36% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 43,000 minutes out of 119,000, against a national NAS share of 21%.
Cancellations run at 4.71%, against 1.89% nationally. That is about one flight in twenty 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 actually costs
14.9% 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.
The 1,076 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The return leg is a different operation and performs like one: it runs 67.9% on time across 4,715 flights, 3 points above 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 3 points of difference.
The sample behind these figures is 4,714 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 delay figures matter less here than the 4.71% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 4,455 completed flights over 12 months sit behind that.
Common questions
FLL to LGA questions
How often is FLL to LGA delayed?
About one flight in three arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 35.2% of the 4,714 flights in this analysis, against 22.7% nationally. Delayed flights are late by a little over an hour on average.
Which airline is most reliable on FLL to LGA?
Delta Air Lines leads at 71.8% on time across 1,590 flights. American Airlines is at the other end on 55.6%, a gap of 16 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 FLL to LGA?
The 5am–8am departure window is the strongest at 87.6% on time. The 5pm–8pm window is the weakest at 53.1%, 34 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 FLL to LGA?
March is the weakest month at 45.8% on time, compared with 81.9% in September. Across the year that is 36 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
