What PUS to CNX looks like
The PUS to CNX sector, the carriers on it and the flying time, before anything is promised to anybody.
Busan PUS to Chiang Mai CNX is a medium haul sector of 3,465 km by great circle, flown nonstop 3 times a week.
At the cruise speed this site models for 3,465 km, 880 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 4h 40m.
Busan PUS is a mid sized airport in the network held here, 48 scheduled destinations and 175 departures a day. Chiang Mai CNX has 29 destinations and 87.6 departures a day.
Chiang Mai is 2 hours behind of Busan 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.

|---|---|---|---|

The clock from collection to signature
The same ground timings the route calculator starts from, applied to the 4h 40m block time on PUS to CNX. Change any of them in the tool further down and the total moves with them.
| Stage | Allowed | Elapsed |
|---|---|---|
| Collection and the run to PUS | 90 min | 1h 30m |
| At PUS before departure | 180 min | 4h 30m |
| PUS to CNX in the air, estimated | 280 min | 9h 10m |

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 PUS to CNX.
| Connecting at | PUS to hub, flights a day | Hub to CNX, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Hanoi HAN | 2.29 | 0.86 | 3,501 | 6h 38m |
| Seoul ICN | 5.86 | 3.29 | 3,720 | 6h 49m |
| Hong Kong HKG | 3 | 1.86 | 3,648 | 6h 55m |
| Shanghai PVG | 5.57 | 2.57 | 3,475 | 6h 56m |
| Taipei TPE | 18.14 | 3.14 | 3,742 | 7h 02m |
| Bangkok BKK | 2.14 | 24.29 | 4,295 | 7h 35m |
12 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Hanoi HAN, where the weaker of the two legs still runs 6 times a week.
Through HAN the routing covers 3,501 km against the 3,465 km nonstop track and takes about 6h 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 58m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Seoul ICN at 6h 49m and Hong Kong HKG at 6h 55m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
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 PUS to CNX 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.
