SUB Surabaya

How deep the SUB board really is

The table above says where a courier can fly from SUB. This reads the same 39 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.

• 22of the 39 destinations are flown by one airline
• 19destinations run less than once a day
• 8destinations have four or more departures a day
• 53.8%of the destinations name Lion Air, the largest presence here

Who holds the departures at SUB

17 airlines appear on the SUB board and they do not hold it evenly. Lion Air is on 21 of the 39 destinations, 53.8 per cent of them, and on 9 of those it is the only airline flying the sector. The destinations it appears on carry 99.5 of the 129.7 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 Citilink on 11 destinations. 8 of the 17 airlines at SUB 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.

An airport held this tightly is quick to book and slow to recover: with 21 of the 39 destinations on one airline, the second aircraft on an SUB sector is usually another Lion Air aircraft, and when there is not one the desk is looking at another airport rather than another airline. That is why the alternate airports listed above matter more at SUB than the destination count does.

How much of the SUB board is daily

Of the 39 destinations, 20 are flown at least once a day and 19 are not, 1 of them running once a week or less. The median destination on the SUB 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: SUB to Medina (MED) 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 71.5 of the 129.7 departures a day, 55.1 per cent of the whole board. More than half of everything that leaves SUB is aimed at those five places, so the depth on the board above is thinner than the destination count suggests, and a hand carry that is not going to one of them is planned around a single departure time.

The ten destinations out of SUB 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. 7 further destinations sit in the same position and are listed in the board above.

The way back from SUB

The desk holds the return direction for 12 of the 39 destinations, and a courier plans the way back on those figures rather than on the outbound. On none of those 12 does the return run more than a quarter thinner than the outbound, so a turnaround through SUB is a question of hours rather than of whether an aircraft exists.

It runs the other way as well: Jeddah (JED) files 1.7 a day back into SUB against 0.31 outbound, which is the shape that strands a courier at this end rather than at the far end.

The clock at SUB

SUB keeps Asia/Jakarta time, three hours ahead of Dubai all year.

When it is 09:00 on a Dubai working morning it is 12:00 at SUB, so a nine to six day at each end overlaps for six hours. A customs question raised in the last three hours of the Dubai afternoon reaches nobody at SUB until the next morning, which is the practical limit on a same day instruction here.

Where SUB turns up on the rest of this site

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

The site publishes 6 airport pair pages that start or end at SUB, each with the distance, the block time, the carriers on the sector and a door to door clock. The busiest are Surabaya to Jakarta (CGK), Surabaya to Denpasar-Bali Island (DPS) and Surabaya to Ujung Pandang-Celebes Island (UPG).

Three courier postings name SUB as the airport a courier here flies from: Surabaya, Malang and Situbondo.

To price a movement rather than read the board, the route calculator opens with SUB already set as the origin, and it works out the flying time, the distance and the delivery hour for any of the 39 destinations above.
