What ICN to SGN looks like
The ICN to SGN sector, the carriers on it and the flying time, before anything is promised to anybody.
Seoul ICN to Ho Chi Minh City SGN is a long haul sector of 3,563 km by great circle, flown nonstop 11.1 times a day.
At the cruise speed this site models for 3,563 km, 880 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 4h 48m.
Seoul ICN is a major hub in the network held here, 165 scheduled destinations and 641.2 departures a day. Ho Chi Minh City SGN has 77 destinations and 380.1 departures a day.
Ho Chi Minh City is 2 hours behind of Seoul 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 ICN to SGN from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| ICN to SGN | 11.14 | 78 | 9G Rail, Asiana Airlines, Korean Air, VietJetAir, Vietnam Airlines |
| SGN to ICN | 9.86 | 69 | 9G Rail, Asiana Airlines, Korean Air, VietJetAir, Vietnam Airlines |
5 carriers are recorded on the sector, so a missed departure is normally a rebooking rather than a lost day.
At 11.1 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 147 departures a week on ICN to SGN, 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 4h 48m block time on ICN to SGN. Change any of them in the tool further down and the total moves with them.
| Stage | Allowed | Elapsed |
|---|---|---|
| Collection and the run to ICN | 90 min | 1h 30m |
| At ICN before departure | 180 min | 4h 30m |
| ICN to SGN in the air, estimated | 288 min | 9h 18m |
| Formalities at SGN | 90 min | 10h 48m |
| Delivery run in Ho Chi Minh City | 45 min | 11h 33m |
| Door to door | 693 min | 11h 33m |
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 ICN to SGN is 11h 33m.
A courier who leaves Seoul at 09:00 local is on the ground in Ho Chi Minh City at about 11:48 local and at the door by 14:03 the same day.
Working backwards from a six in the evening handover in Ho Chi Minh City, the last useful departure from Seoul is around 12:57 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. 46 of them join ICN to SGN.
| Connecting at | ICN to hub, flights a day | Hub to SGN, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Xiamen XMN | 2.43 | 2.29 | 3,589 | 6h 35m |
| Nanjing NKG | 4.14 | 1 | 3,585 | 6h 35m |
| Da Nang DAD | 14.71 | 39.86 | 3,586 | 6h 41m |
| Kaohsiung KHH | 3.43 | 3 | 3,712 | 6h 45m |
| Busan PUS | 5.86 | 2 | 3,861 | 6h 45m |
| Hong Kong HKG | 23.86 | 6.57 | 3,563 | 6h 48m |
With 11.1 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.
46 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Xiamen XMN, where the weaker of the two legs still runs about twice a day.
Through XMN the routing covers 3,589 km against the 3,563 km nonstop track and takes about 6h 35m 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 47m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Nanjing NKG at 6h 35m and Da Nang DAD at 6h 41m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
If nothing suitable leaves Ho Chi Minh City, Phnom Penh PNH is 213 km away by great circle and carries 25 scheduled destinations of its own, which is usually a shorter road transfer than a lost day.

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 ICN to SGN 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.
