What SIN to SUB looks like
The SIN to SUB sector, the carriers on it and the flying time, before anything is promised to anybody.
Singapore SIN to Surabaya SUB is a medium haul sector of 1,376 km by great circle, flown nonstop 5.4 times a day.
At the cruise speed this site models for 1,376 km, 830 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 2h 15m.
Singapore SIN is a major hub in the network held here, 159 scheduled destinations and 536.3 departures a day. Surabaya SUB has 39 destinations and 129.7 departures a day.
Singapore carries about 4.1 times the departures of Surabaya, so a courier who has to be rebooked has far more to work with at one end of this pair than at the other.
Surabaya is one hour behind of Singapore all year.
The pair sits inside Asia Pacific, a corridor where the site already publishes 16 written lanes that go into customs and ground detail this page does not.
Who flies the sector, and how often
Average daily frequencies on SIN to SUB from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| SIN to SUB | 5.43 | 38 | Scoot, Singapore Airlines |
| SUB to SIN | 5.43 | 38 | Scoot, Singapore Airlines |
Two carriers hold the sector, Scoot and Singapore Airlines, which gives a missed departure somewhere to go without leaving the nonstop.
At 5.4 times a day there is usually another departure within a few hours, which is what makes a same day booking on this pair realistic.
Between them the two directions put about 76 departures a week on SIN to SUB, which is the number that decides whether a seat can be found today or on Thursday.
The clock from collection to signature
The same ground timings the route calculator starts from, applied to the 2h 15m block time on SIN to SUB. Change any of them in the tool further down and the total moves with them.
| Stage | Allowed | Elapsed |
|---|---|---|
| Collection and the run to SIN | 90 min | 1h 30m |
| At SIN before departure | 180 min | 4h 30m |
| SIN to SUB in the air, estimated | 135 min | 6h 45m |
| Formalities at SUB | 90 min | 8h 15m |
| Delivery run in Surabaya | 45 min | 9h 00m |
| Door to door | 540 min | 9h 00m |
On the desk standard ground timings, ninety minutes to collect and reach the airport, three hours at the airport before departure, ninety minutes of arrival formalities and a forty five minute delivery run, the door to door figure for SIN to SUB is 9h 00m.
A courier who leaves Singapore at 09:00 local is on the ground in Surabaya at about 10:15 local and at the door by 12:30 the same day.
Working backwards from a six in the evening handover in Surabaya, the last useful departure from Singapore is around 14:30 local.
When the nonstop does not work
Every airport that joins the two ends, ranked by when they land, among the ones whose weaker leg is dependable enough to plan on. Connection time is allowed for the size of the hub. 11 of them join SIN to SUB.
| Connecting at | SIN to hub, flights a day | Hub to SUB, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Jakarta CGK | 30.71 | 27.57 | 1,573 | 4h 09m |
| Bali DPS | 18.43 | 13 | 1,974 | 4h 35m |
| Kuala Lumpur KUL | 43 | 7.86 | 1,965 | 4h 49m |
| Lombok LOP | 1.57 | 6.71 | 2,179 | 4h 52m |
| Penang PEN | 14.57 | 1 | 2,580 | 5h 25m |
| Bandar Seri Begawan BWN | 2.86 | 0.86 | 2,669 | 5h 25m |
With 5.4 times a day on the nonstop, a connection here is a disruption plan rather than a routing, and it is listed because a closed runway or a cancellation wave is exactly when nobody has time to work it out.
11 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Jakarta CGK, where the weaker of the two legs still runs 27.6 times a day.
Through CGK the routing covers 1,573 km against the 1,376 km nonstop track and takes about 4h 09m in the air and on the ground at the hub, allowing 60 minutes to connect at an airport of that size.
That is only 1h 54m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Bali DPS at 4h 35m and Kuala Lumpur KUL at 4h 49m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.

Where this came from, and where to look next
- Carriers and frequencies: AeroDataBox scheduled route statistics, retrieved 2026-09-07. Average daily flights, not a timetable.
- Distances: great circle from published coordinates. They read short against a flown track, which is why the block time above applies a factor to them.
- Block and connection times: the same model the route calculator lower down this page runs, at the same rounding.
- Restrictions: the airport notes file, checked 2026-09-07.
- Industrial sites: public company information. Nothing here says or implies that any company named is a customer of any courier operator.
Who publishes this. OnBoard Courier is a placement desk in Dubai. An assignment is carried out by a vetted partner operator, with the desk as the single point of contact from the quote to the signature. This page exists because our own dispatchers need the answer for SIN to SUB in the twenty minutes before a promise is made, and a reference only one operator can read is not a reference. Free to read, quote and cite. Found an error? Tell us and we will correct it.
If you need something moved rather than looked up, the desk prices a hand carry in fifteen minutes.
