What CSX to TSN looks like
The CSX to TSN sector, the carriers on it and the flying time, before anything is promised to anybody.
Changsha CSX to Tianjin TSN is a medium haul sector of 1,274 km by great circle, flown nonstop 6.3 times a day.
At the cruise speed this site models for 1,274 km, 830 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 2h 08m.
Changsha CSX is a large airport in the network held here, 101 scheduled destinations and 293.9 departures a day. Tianjin TSN has 79 destinations and 183.7 departures a day.
Changsha and Tianjin keep the same clock all year, so the arrival time is the departure time plus the block and nothing else.
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 CSX to TSN from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| CSX to TSN | 6.29 | 44 | Air China, China Southern Airlines, Hainan Airlines, Okay Airways, Xiamen Airlines |
| TSN to CSX | 5.86 | 41 | Air China, China Southern Airlines, Hainan Airlines, Okay Airways, Xiamen Airlines |
5 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 85 departures a week on CSX 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 2h 08m block time on CSX 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 CSX | 90 min | 1h 30m |
| At CSX before departure | 180 min | 4h 30m |
| CSX to TSN in the air, estimated | 128 min | 6h 38m |
| Formalities at TSN | 90 min | 8h 08m |
| Delivery run in Tianjin | 45 min | 8h 53m |
| Door to door | 533 min | 8h 53m |
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 CSX to TSN is 8h 53m.

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. 19 of them join CSX to TSN.
| Connecting at | CSX to hub, flights a day | Hub to TSN, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Shanghai SHA | 8 | 9 | 1,805 | 4h 18m |
| Xian XIY | 12.86 | 9.86 | 1,740 | 4h 28m |
| Hangzhou HGH | 1 | 4.72 | 1,764 | 4h 39m |
| Shanghai PVG | 4.14 | 5.86 | 1,867 | 4h 53m |
| Fuzhou FOC | 4 | 2.45 | 2,167 | 4h 55m |
| Xiamen XMN | 8.43 | 4.86 | 2,258 | 5h 00m |
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.
19 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Shanghai SHA, where the weaker of the two legs still runs 8 times a day.
Through SHA the routing covers 1,805 km against the 1,274 km nonstop track and takes about 4h 18m in the air and on the ground at the hub, allowing 60 minutes to connect at an airport of that size.
That is only 2h 10m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Xian XIY at 4h 28m and Hangzhou HGH at 4h 39m 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 CSX 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.
