What ICN to TSN looks like
The ICN to TSN sector, the carriers on it and the flying time, before anything is promised to anybody.
Seoul ICN to Tianjin TSN is a short sector of 815 km by great circle, flown nonstop 6 times a day.
At the cruise speed this site models for 815 km, 830 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 1h 32m.
Seoul ICN is a major hub in the network held here, 165 scheduled destinations and 641.2 departures a day. Tianjin TSN has 79 destinations and 183.7 departures a day.
Seoul carries about 3.5 times the departures of Tianjin, so a courier who has to be rebooked has far more to work with at one end of this pair than at the other.
Tianjin is one hour 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 TSN from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| ICN to TSN | 6 | 42 | Air China, Air Incheon, Asiana Airlines, Korean Air, Tianjin Airlines |
| TSN to ICN | 5.71 | 40 | Air China, Asiana Airlines, Korean Air, Tianjin Airlines |
5 carriers are recorded on the sector, so a missed departure is normally a rebooking rather than a lost day.
At 6 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 TSN, 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 32m block time on ICN to TSN. 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 TSN in the air, estimated | 92 min | 6h 02m |
| Formalities at TSN | 90 min | 7h 32m |
| Delivery run in Tianjin | 45 min | 8h 17m |
| Door to door | 497 min | 8h 17m |
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 TSN is 8h 17m.
A courier who leaves Seoul at 09:00 local is on the ground in Tianjin at about 09:32 local and at the door by 11:47 the same day.
Working backwards from a six in the evening handover in Tianjin, the last useful departure from Seoul is around 15:13 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. 20 of them join ICN to TSN.
| Connecting at | ICN to hub, flights a day | Hub to TSN, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Harbin HRB | 4 | 5 | 1,934 | 4h 29m |
| Shanghai PVG | 22.43 | 5.86 | 1,797 | 4h 48m |
| Hangzhou HGH | 3.86 | 4.72 | 2,006 | 4h 49m |
| Wuhan WUH | 2 | 5.86 | 2,318 | 5h 12m |
| Xian XIY | 3.29 | 9.86 | 2,550 | 5h 31m |
| Fuzhou FOC | 1.86 | 2.45 | 2,915 | 5h 44m |
With 6 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.
20 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Harbin HRB, where the weaker of the two legs still runs 4 times a day.
Through HRB the routing covers 1,934 km against the 815 km nonstop track and takes about 4h 29m in the air and on the ground at the hub, allowing 60 minutes to connect at an airport of that size.
That is 2h 57m more than the nonstop, which is the price of a missed departure on this pair.
Behind it, Shanghai PVG at 4h 48m and Hangzhou HGH at 4h 49m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
If nothing suitable leaves Tianjin, Beijing PKX is 91 km away by great circle and carries 159 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 TSN 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.
