SJU across all twelve months

These figures cover 2,835 departures from Luis Munoz Marin International in February 2026. 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

February next to SJU's other months

Against SJU's own year, February ran 3 points worse than the twelve-month rate of 77.8%, which makes it number ten of twelve months, best first. Cancellations are where February stands out: 3.17% of scheduled departures were called off, 1.7 times the airport's rate across the year. Either side of it, January ran 73.3% on time and March 75.1%, so this month sits in line with its neighbours.

Departure window

The best time of day to leave SJU in February

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 24 points, against 15 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am563 flights83.3%
  • 8am–11am328 flights90.7%
  • 11am–2pm304 flights76.2%
  • 2pm–5pm843 flights67.3%
  • 5pm–8pm550 flights70.2%
  • 8pm–5am247 flights67.2%

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.

Book the morning departure. Flights leaving between 8am–11am arrive on time 90.7% of the time, against 67.2% for the overnight window. That is 24 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 843 flights scheduled in it.

Across the week, Thursday is the strongest day at 79.4% on time and Saturday the weakest at 68.7%. 11 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at SJU in February

Delay causes

What held SJU up in February

One category carries most of the weight here. Late-arriving aircraft accounts for 55% of the 55,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

  • Late-arriving aircraft
    55%
  • Carrier
    29%
  • National Airspace System
    15%
  • Extreme weather
    1%
  • Security
    0%

55% 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 55,000 reported delay minutes here, that single category outweighs weather by 55 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. The split is drawn from 54,589 reported delay minutes.

Cancellations run at 3.17%, against 2.25% 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.

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.3% of arrivals land a full hour or more behind schedule, against 6.5% 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.

What to do with this

Flying from SJU in February

For a February trip through SJU: plan on this being one of the airport's harder months. The 8am–11am departures held up best at 90.7% on time, and with 9.3% of arrivals an hour or more late, a connection here deserves more slack than the same trip in May would.
