SJU San Juan

How deep the SJU board really is

The table above says where a courier can fly from SJU. This reads the same 59 destinations back for the questions a dispatcher asks second: how much of the board rests on one airline, how much of it runs less than daily, whether the return leg is as thick as the outbound and what the clock here does to a Gulf working day, all of it computed on 2026-09-07 from AeroDataBox scheduled route statistics.

• 33of the 59 destinations are flown by one airline
• 21destinations run less than once a day
• 18destinations have four or more departures a day
• 35.6%of the destinations name JetBlue Airways, the largest presence here

Who holds the departures at SJU

34 airlines appear on the SJU board and they do not hold it evenly. JetBlue Airways is on 21 of the 59 destinations, 35.6 per cent of them, and on 6 of those it is the only airline flying the sector. The destinations it appears on carry 104.9 of the 177.8 departures a day this airport files, though other airlines fly some of the same sectors, so read that as reach rather than as a share of the aircraft.

The next largest presence is Frontier Airlines on 12 destinations. 14 of the 34 airlines at SJU appear on a single destination each, which is the long tail every airport carries, and none of it is a rebooking option when the sector you need is the one that fell over.

That is a middling concentration at SJU: one airline on 35.6 per cent of the destinations and the other 64.4 per cent spread across 33 airlines. A cancellation inside the JetBlue Airways network is often survivable inside the same booking, but on the 38 destinations JetBlue Airways does not touch, a rebooking means moving to a carrier the desk has to check for a through fare first.

How much of the SJU board is daily

Of the 59 destinations, 38 are flown at least once a day and 21 are not, 12 of them running once a week or less. The median destination on the SJU board is flown about once a day.

An average of 0.14 flights a day is the schedule statistic, and it is worth translating it before anything is promised to anybody: SJU to Westhampton Beach (FOK) is about one a week, so a missed departure there is not a delay of hours, it is the next slot.

The five busiest destinations carry 60.9 of the 177.8 departures a day, 34.2 per cent of the whole board. The other 54 destinations are spread widely enough that a courier who misses the first departure at SJU usually has somewhere else to look on the same board.

The ten destinations out of SJU where one airline holds the sector and files fewer than seven departures a week, with the weekly figure taken as the average daily rate multiplied by seven rather than as a fixed timetable. 10 further destinations sit in the same position and are listed in the board above.

The way back from SJU

The desk holds the return direction for 25 of the 59 destinations, and a courier plans the way back on those figures rather than on the outbound. On none of those 25 does the return run more than a quarter thinner than the outbound, so a turnaround through SJU is a question of hours rather than of whether an aircraft exists.

The clock at SJU

SJU keeps America/Puerto_Rico time, eight hours behind Dubai all year.

When it is 09:00 on a Dubai working morning it is 01:00 at SJU, so a nine to six day at each end overlaps for an hour. That is a narrow window for a signature, a customs query or an authority to release, and it is the reason a consignment for SJU is briefed the day before rather than on the morning it flies.

Where SJU turns up on the rest of this site

The airport also sits behind the Puerto Rico country desk, which sets out the customs practice, the working week and the road legs behind this airport.

The site publishes 1 airport pair page that start or end at SJU, each with the distance, the block time, the carriers on the sector and a door to door clock. The busiest are San Juan to Bogotá (BOG).

Three courier postings name SJU as the airport a courier here flies from: San Juan, Carolina and Ponce.

To price a movement rather than read the board, the route calculator opens with SJU already set as the origin, and it works out the flying time, the distance and the delivery hour for any of the 59 destinations above.
