What ICN to SZX looks like
The ICN to SZX sector, the carriers on it and the flying time, before anything is promised to anybody.
Seoul ICN to Shenzhen SZX is a medium haul sector of 2,045 km by great circle, flown nonstop 6.3 times a day.
At the cruise speed this site models for 2,045 km, 830 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 3h 07m.
Seoul ICN is a major hub in the network held here, 165 scheduled destinations and 641.2 departures a day. Shenzhen SZX has 157 destinations and 574.7 departures a day.
Shenzhen 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 SZX from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| ICN to SZX | 6.29 | 44 | Asiana Airlines, Atlas Air, China Central Airlines, China Southern Airlines, Korean Air, Shenzhen Airlines |
| SZX to ICN | 5.57 | 39 | Asiana Airlines, China Southern Airlines, Korean Air, Shenzhen Airlines |
6 carriers are recorded on the sector, so a missed departure is normally a rebooking rather than a lost day.
At 6.3 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 83 departures a week on ICN to SZX, 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 3h 07m block time on ICN to SZX. Change any of them in the tool further down and the total moves with them.

| Formalities at SZX | 90 min | 9h 07m |
| Delivery run in Shenzhen | 45 min | 9h 52m |

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. 43 of them join ICN to SZX.
| Connecting at | ICN to hub, flights a day | Hub to SZX, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Nanjing NKG | 4.14 | 19.14 | 2,070 | 4h 38m |
| Hangzhou HGH | 3.86 | 29 | 2,049 | 4h 52m |
| Shanghai PVG | 22.43 | 17.71 | 2,055 | 5h 07m |
| Taipei TPE | 14.14 | 4.29 | 2,266 | 5h 08m |
| Wuhan WUH | 2 | 7.29 | 2,255 | 5h 08m |
| Tianjin TSN | 6 | 7 | 2,678 | 5h 25m |
With 6.3 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.
43 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Nanjing NKG, where the weaker of the two legs still runs 4.1 times a day.
Through NKG the routing covers 2,070 km against the 2,045 km nonstop track and takes about 4h 38m 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 31m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Hangzhou HGH at 4h 52m and Shanghai PVG at 5h 07m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
If nothing suitable leaves Shenzhen, Hong Kong HKG is 38 km away by great circle and carries 144 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 SZX 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.
