What SIN to DEL looks like
The SIN to DEL sector, the carriers on it and the flying time, before anything is promised to anybody.
Singapore SIN to Delhi DEL is a long haul sector of 4,159 km by great circle, flown nonstop 6.4 times a day.
At the cruise speed this site models for 4,159 km, 880 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 5h 31m.
Singapore SIN is a major hub in the network held here, 159 scheduled destinations and 536.3 departures a day. Delhi DEL has 133 destinations and 607.8 departures a day.
Delhi is 2.5 hours 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 DEL from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| SIN to DEL | 6.43 | 45 | Air India, IndiGo, Singapore Airlines |
| DEL to SIN | 6.29 | 44 | Air India, IndiGo, Singapore Airlines |
3 carriers are recorded on the sector, so a missed departure is normally a rebooking rather than a lost day.
At 6.4 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 89 departures a week on SIN to DEL, 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 5h 31m block time on SIN to DEL. 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 DEL in the air, estimated | 331 min | 10h 01m |
| Formalities at DEL | 90 min | 11h 31m |
| Delivery run in Delhi | 45 min | 12h 16m |
| Door to door | 736 min | 12h 16m |
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 DEL is 12h 16m.
A courier who leaves Singapore at 09:00 local is on the ground in Delhi at about 12:01 local and at the door by 14:16 the same day.
Working backwards from a six in the evening handover in Delhi, the last useful departure from Singapore is around 12:44 local.
At 12h 16m the mission uses most of a sixteen hour duty day, which leaves no room for a delay before a rest at the far end becomes the honest answer.
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. 58 of them join SIN to DEL.
| Connecting at | SIN to hub, flights a day | Hub to DEL, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Phuket HKT | 8.43 | 3.43 | 4,159 | 7h 05m |
| Kathmandu KTM | 1.14 | 12 | 4,353 | 7h 18m |
| Kuala Lumpur KUL | 43 | 4.86 | 4,175 | 7h 21m |
| Kolkata CCU | 1.14 | 20.09 | 4,217 | 7h 24m |
| Dhaka DAC | 3.57 | 2.29 | 4,323 | 7h 31m |
| Bangkok DMK | 2.71 | 0.71 | 4,367 | 7h 35m |
With 6.4 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.
58 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Phuket HKT, where the weaker of the two legs still runs 3.4 times a day.
Through HKT the routing covers 4,159 km against the 4,159 km nonstop track and takes about 7h 05m 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 34m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Kathmandu KTM at 7h 18m and Kuala Lumpur KUL at 7h 21m 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 DEL 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.
