What CJU to SZX looks like

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. 12 of them join CJU to SZX.
| Connecting at | CJU to hub, flights a day | Hub to SZX, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Nanjing NKG | 3.14 | 19.14 | 1,869 | 4h 31m |
| Hangzhou HGH | 2.57 | 29 | 1,749 | 4h 37m |
| Taipei TPE | 4.57 | 4.29 | 1,869 | 4h 38m |
| Shanghai PVG | 12.71 | 17.71 | 1,746 | 4h 49m |
| Beijing PKX | 1.86 | 17 | 3,012 | 6h 06m |
| Osaka KIX | 1.14 | 1 | 3,275 | 6h 11m |
One nonstop a day means one chance a day, so the connections below are what a consignment that arrives at CJU in the afternoon actually flies on.
12 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 3.1 times a day.
Through NKG the routing covers 1,869 km against the 1,732 km nonstop track and takes about 4h 31m 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 48m 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 37m and Taipei TPE at 4h 38m 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 CJU 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.
