PBI across all twelve months

These figures cover 3,186 departures from Palm Beach International in December 2025. On time means an arrival less than 15 minutes after the scheduled gate time, the DOT's threshold, and the national comparison uses every US departure in the same month rather than the whole year.

Against the year

December next to PBI's other months

Against PBI's own year, December ran 3 points worse than the twelve-month rate of 75.1%, which makes it number nine of eleven months, best first. Either side of it, November ran 76.8% on time and January 74.7%, so a trip moved by a few weeks would have landed in a better stretch.

Departure window

The best time of day to leave PBI in December

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 33 points, against 12 points between the best and worst carrier.

  • 5am–8am462 flights92.7%
  • 8am–11am503 flights85.4%
  • 11am–2pm733 flights71.2%
  • 2pm–5pm570 flights61.7%
  • 5pm–8pm658 flights59.9%
  • 8pm–5am260 flights60.3%

Scale runs 50% to 100%.

The 5pm–8pm window is where this operation falls apart: 59.9% on time, against 92.7% 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 11am–2pm window is the busiest, with 733 flights scheduled in it.

Across the week, Wednesday is the strongest day at 87.8% on time and Sunday the weakest at 51.6%, a spread of 36 points.

Carrier by carrier

Which airlines ran best at PBI in December

The choice of carrier is not cosmetic here. American Airlines arrives on time 78.0% of the time; JetBlue Airways manages 66.1%. Sample sizes sit next to every figure, because a two-point gap across 910 flights means less than a ten-point one.

Delay causes

What held PBI up in December

Late-arriving aircraft accounts for 57% of the 70,000 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    57%
  • Carrier
    25%
  • National Airspace System
    16%
  • Extreme weather
    1%
  • Security
    0%

57% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 70,000 reported delay minutes here, that single category outweighs weather by 57 to one. The split is drawn from 70,000 reported delay minutes.

Cancellations sit at 1.95% against a national 1.55%, which is ordinary. Diversions add another 0.28%.

12.2% of arrivals land a full hour or more behind schedule, against 10.0% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.

What to do with this

Flying from PBI in December

For a December trip through PBI: plan on this being one of the airport's harder months. The 5am–8am departures held up best at 92.7% on time, and with 12.2% of arrivals an hour or more late, a connection here deserves more slack than the same trip in May would.
