C−GRADE

JetBlue Airways at West Palm Beach carries a cancellation problem, not just a delay problem: 3.5% 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 8,463 flights, of which Southwest Airlines flew 2,601 at 78.8% on time.

Measured against the airport rather than the country, JetBlue Airways runs 4 points behind the 75.1% 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.

Against the competition

Every carrier at PBI, ranked

The choice of carrier is not cosmetic here. Southwest Airlines arrives on time 78.8% of the time; Frontier Airlines manages 53.8%. Sample sizes sit next to every figure, because a two-point gap across 436 flights means less than a ten-point one.

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 34 points, against 25 points between the best and worst carrier.

  • 5am–8am1,290 flights93.4%
  • 8am–11am1,522 flights82.4%
  • 11am–2pm1,480 flights71.6%
  • 2pm–5pm1,383 flights59.9%
  • 5pm–8pm1,909 flights59.4%
  • 8pm–5am879 flights63.2%

Scale runs 50% to 100%.

The 5pm–8pm window is where this operation falls apart: 59.4% on time, against 93.4% 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 1,909 flights scheduled in it.

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. March was the busiest month here, with 992 flights.

50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 179,000 reported delay minutes here, that single category outweighs weather by 50 to one. The split is drawn from 179,355 reported delay minutes.

Cancellations run at 3.54%, against 1.89% nationally. That is about 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.

12.7% 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 sample behind these figures is 8,463 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 3.54% 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. 8,116 completed flights over 12 months sit behind that.

Common questions

JetBlue Airways at PBI

How often is JetBlue Airways at 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 28.6% of the 8,463 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 JetBlue Airways at PBI?

Southwest Airlines leads at 78.8% on time across 2,601 flights. Frontier Airlines is at the other end on 53.8%, 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 93.4% on time. The 5pm–8pm window is the weakest at 59.4%, 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 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.
