This route carries a cancellation problem, not just a delay problem: 4.3% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, about seven flights in ten arrive on time, worth a C− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 3,008 LGA to PBI flights, of which Delta Air Lines flew 1,434 at 71.9% on time.
Best time to fly LGA to PBI: a 5am–8am departure, ideally on a Wednesday. Flights in that window arrived on time 87.6% of the time and Wednesday flights 75.5%, against 70.2% for the route overall.
Delta Air Lines is the most reliable of the three carriers covered here at 71.9% on time across 1,434 flights.

Carrier by carrier
Which airline is most reliable on LGA to PBI
The three carriers here are closely matched: 5 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Republic Airwaysthin sample | 117 | 75.0% | 48 min | 5.98% | B− |
| Delta Air Lines | 1,434 | 71.9% | 69 min | 4.32% | C− |

| JetBlue Airways | 1,052 | 67.2% | 73 min | 4.28% | C− |
Delta Air Lines cancels 4.3% 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.

The most reliable ways to fly New York to West Palm Beach
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 29 points, against 5 points between the best and worst carrier.
- 5am–8am583 flights87.6%
- 8am–11am641 flights72.3%
- 11am–2pm539 flights71.7%
- 2pm–5pm728 flights58.8%
- 5pm–8pm265 flights59.6%
- 8pm–5am252 flights65.0%
Scale runs 50% to 95%.
Book the early departure. Flights leaving between 5am–8am arrive on time 87.6% of the time, against 58.8% for the afternoon window. That is 29 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 2pm–5pm window is the busiest, with 728 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 23 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.
December is the weak month at 59.5% on time, against 82.0% in June. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. January was the busiest month here, with 339 flights.
Across the week, Wednesday is the strongest day at 75.5% on time and Sunday the weakest at 61.8%, a spread of 14 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 64,000 reported delay minutes.
- 38%Late-arriving aircraft
- 30%Carrier
- 30%National Airspace System
- 2%Extreme weather
- 0%Security
38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 64,000 reported delay minutes here, that single category outweighs weather by 19 to one. The split is drawn from 64,344 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 87.6% on time here.
Cancellations run at 4.32%, against 1.89% nationally. That is about one flight in 25 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
12.2% 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 1,035 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 runs 68.1% on time across 3,008 flights, within 2 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 3,008 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 4.32% 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. 2,869 completed flights over 12 months sit behind that.
Common questions
LGA to PBI questions
How often is LGA to PBI delayed?
Roughly 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 29.8% of the 3,008 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 LGA to PBI?
Delta Air Lines leads at 71.9% on time across 1,434 flights. JetBlue Airways is at the other end on 67.2%, a gap of 5 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 LGA to PBI?
The 5am–8am departure window is the strongest at 87.6% on time. The 2pm–5pm window is the weakest at 58.8%, 29 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 December delays on LGA to PBI?
December is the weakest month at 59.5% on time, compared with 82.0% in June. Across the year that is 23 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
