What CJU to NKG looks like
The CJU to NKG sector, the carriers on it and the flying time, before anything is promised to anybody.
Jeju CJU to Nanjing NKG is a short sector of 741 km by great circle, flown nonstop 3.1 times a day.
At the cruise speed this site models for 741 km, 720 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 1h 35m.
Jeju CJU is a smaller airport in the network held here, 34 scheduled destinations and 294.6 departures a day. Nanjing NKG has 85 destinations and 360.8 departures a day.
Nanjing is one hour behind of Jeju 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 CJU to NKG from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| CJU to NKG | 3.14 | 22 | Juneyao Airlines, Spring Airlines |
| NKG to CJU | 3.14 | 22 | Juneyao Airlines, Spring Airlines |
Two carriers hold the sector, Juneyao Airlines and Spring Airlines, which gives a missed departure somewhere to go without leaving the nonstop.
At 3.1 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 44 departures a week on CJU to NKG, 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 35m block time on CJU to NKG. Change any of them in the tool further down and the total moves with them.
| Stage | Allowed | Elapsed |
|---|---|---|
| Collection and the run to CJU | 90 min | 1h 30m |
| At CJU before departure | 180 min | 4h 30m |
| CJU to NKG in the air, estimated | 95 min | 6h 05m |
| Formalities at NKG | 90 min | 7h 35m |
| Delivery run in Nanjing | 45 min | 8h 20m |
| Door to door | 500 min | 8h 20m |
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 CJU to NKG is 8h 20m.
A courier who leaves Jeju at 09:00 local is on the ground in Nanjing at about 09:35 local and at the door by 11:50 the same day.

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. 13 of them join CJU to NKG.
| Connecting at | CJU to hub, flights a day | Hub to NKG, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Shanghai PVG | 12.71 | 2.43 | 800 | 3h 40m |
| Busan PUS | 34.29 | 0.86 | 1,300 | 3h 43m |
| Taipei TPE | 4.57 | 1.29 | 1,843 | 4h 46m |
| Beijing PKX | 1.86 | 3.43 | 2,012 | 4h 49m |
| Kaohsiung KHH | 1.29 | 0.57 | 2,386 | 5h 03m |
| Beijing PEK | 2.29 | 5.86 | 2,093 | 5h 11m |
With 3.1 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.
13 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Shanghai PVG, where the weaker of the two legs still runs about twice a day.
Through PVG the routing covers 800 km against the 741 km nonstop track and takes about 3h 40m in the air and on the ground at the hub, allowing 90 minutes to connect at an airport of that size.
That is only 2h 05m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Busan PUS at 3h 43m and Taipei TPE at 4h 46m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
If nothing suitable leaves Nanjing, Hangzhou HGH is 225 km away by great circle and carries 117 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 CJU to NKG 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.
