What ICN to PUS looks like
The ICN to PUS sector, the carriers on it and the flying time, before anything is promised to anybody.
Seoul ICN to Busan PUS is a short sector of 338 km by great circle, flown nonstop 5.9 times a day.
At the cruise speed this site models for 338 km, 720 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 1h 00m.
Seoul ICN is a major hub in the network held here, 165 scheduled destinations and 641.2 departures a day. Busan PUS has 48 destinations and 175 departures a day.
Seoul carries about 3.7 times the departures of Busan, so a courier who has to be rebooked has far more to work with at one end of this pair than at the other.
Seoul and Busan keep the same clock all year, so the arrival time is the departure time plus the block and nothing else.
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 PUS from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| ICN to PUS | 5.86 | 41 | Korean Air, VietJetAir |
| PUS to ICN | 5.86 | 41 | Korean Air, VietJetAir |
Two carriers hold the sector, Korean Air and VietJetAir, which gives a missed departure somewhere to go without leaving the nonstop.
At 5.9 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 82 departures a week on ICN to PUS, 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 1h 00m block time on ICN to PUS. 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 PUS in the air, estimated | 60 min | 5h 30m |
| Formalities at PUS | 90 min | 7h 00m |
| Delivery run in Busan | 45 min | 7h 45m |
| Door to door | 465 min | 7h 45m |
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 PUS is 7h 45m.
A courier who leaves Seoul at 09:00 local is on the ground in Busan at about 10:00 local and at the door by 12:15 the same day.
Working backwards from a six in the evening handover in Busan, the last useful departure from Seoul is around 14:45 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. 31 of them join ICN to PUS.
| Connecting at | ICN to hub, flights a day | Hub to PUS, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Fukuoka FUK | 29.29 | 13.43 | 788 | 3h 10m |
| Osaka KIX | 41.29 | 13.71 | 1,442 | 3h 57m |
| Nagoya NGO | 9.14 | 2.29 | 1,690 | 4h 18m |
| Nanjing NKG | 4.14 | 0.86 | 1,951 | 4h 29m |
| Shanghai PVG | 22.43 | 5.43 | 1,623 | 4h 34m |
| Okinawa OKA | 6.86 | 1.86 | 2,265 | 4h 53m |
With 5.9 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.
31 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Fukuoka FUK, where the weaker of the two legs still runs 13.4 times a day.
Through FUK the routing covers 788 km against the 338 km nonstop track and takes about 3h 10m in the air and on the ground at the hub, allowing 60 minutes to connect at an airport of that size.
That is only 2h 10m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Osaka KIX at 3h 57m and Nagoya NGO at 4h 18m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
The two ends are only 338 km apart in a straight line. Allowing a road track a quarter longer than that and eighty kilometres an hour, a car covers it in about 5h 17m, so a courier who misses the flight drives rather than connects, and on a short deadline the road is often the plan from the start.
If nothing suitable leaves Busan, Fukuoka FUK is 225 km away by great circle and carries 47 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 PUS 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.
