JetBlue Airways at West Palm Beach sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 7 points worse than the national rate of 77.4%. The late ones land a little over an hour behind schedule. That rests on 8,865 flights, of which Southwest Airlines flew 2,831 at 77.6% on time.
Measured against the airport rather than the country, JetBlue Airways runs 3 points behind the 74.1% weighted average across all carriers at PBI. That is the comparison worth making: every operator here works the same runways, the same airspace and the same weather.

#6
Of 8 carriers clearing the floor at PBI
These figures cover 8,865 flights between June 2025 and May 2026. Beyond the headline rate, 13.0% 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.
Against the competition
Every carrier at PBI, ranked
The choice of carrier is not cosmetic here. Southwest Airlines arrives on time 77.6% of the time; Frontier Airlines manages 52.3%. Sample sizes sit next to every figure, because a two-point gap across 480 flights means less than a ten-point one.

Spirit Airlines cancels 6.7% 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.
Route by route
Where JetBlue Airways flies from PBI
JetBlue Airways operates 10 routes out of PBI with enough volume to report. Route records inside one carrier at one airport still spread widely, because a short shuttle and a transcontinental have very different exposure to a late inbound.

Departure window
Best time of day for this operation
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 35 points, against 25 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1,422 flights93.6%
- 8am–11am1,484 flights83.6%
- 11am–2pm1,699 flights69.3%
- 2pm–5pm1,382 flights58.2%
- 5pm–8pm2,013 flights58.9%
- 8pm–5am865 flights60.7%
Scale runs 50% to 100%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 93.6% of the time, against 58.2% for the afternoon window. That is 35 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on.
Across the year
Seasonal pattern
May is the best month on the calendar at 82.5% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back.

49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 195,000 reported delay minutes here, that single category outweighs weather by 49 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit.
Cancellations run at 3.00%, against 1.80% nationally. That is roughly one flight in 30 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.
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 13.0% of arrivals land a full hour or more behind schedule, against 8.2% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
The sample behind these figures is 8,865 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.
Put together: the delay figures matter less here than the 3.00% 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.
Common questions
JetBlue Airways at PBI
How often is JetBlue Airways at PBI delayed?
Roughly one flight in three arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 29.3% of the 8,865 flights in this analysis, against 22.6% nationally. Delayed flights are late by a little over an hour on average.
Which airline is most reliable on JetBlue Airways at PBI?
Southwest Airlines leads at 77.6% on time across 2,831 flights. Frontier Airlines is at the other end on 52.3%, a gap of 25 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 JetBlue Airways at PBI?
The 5am–8am departure window is the strongest at 93.6% on time. The 2pm–5pm window is the weakest at 58.2%, 35 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 JetBlue Airways at PBI?
March is the weakest month at 64.4% on time, compared with 82.5% in May. Across the year that is 18 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
