What CTU to CSX looks like
The CTU to CSX sector, the carriers on it and the flying time, before anything is promised to anybody.
Chengdu CTU to Changsha CSX is a short sector of 937 km by great circle, flown nonstop 10.4 times a day.
At the cruise speed this site models for 937 km, 830 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 1h 42m.
Chengdu CTU is a mid sized airport in the network held here, 67 scheduled destinations and 357.2 departures a day. Changsha CSX has 101 destinations and 293.9 departures a day.
Chengdu and Changsha 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 CTU to CSX from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| CTU to CSX | 10.43 | 73 | Air China, Chengdu Airlines, Sichuan Airlines, Tibet Airlines |
| CSX to CTU | 7.43 | 52 | Air China, Sichuan Airlines |
4 carriers are recorded on the sector, so a missed departure is normally a rebooking rather than a lost day.
The two directions are not level: CTU to CSX runs 10.4 times a day, the return runs 7.4 times a day, and a round trip has to be planned around the thinner of the two.
At 10.4 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 125 departures a week on CTU to CSX, 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 42m block time on CTU to CSX. Change any of them in the tool further down and the total moves with them.
| Stage | Allowed | Elapsed |
|---|---|---|
| Collection and the run to CTU | 90 min | 1h 30m |
| At CTU before departure | 180 min | 4h 30m |
| CTU to CSX in the air, estimated | 102 min | 6h 12m |
| Formalities at CSX | 90 min | 7h 42m |
| Delivery run in Changsha | 45 min | 8h 27m |
| Door to door | 507 min | 8h 27m |
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 CTU to CSX is 8h 27m.
A courier who leaves Chengdu at 09:00 local is on the ground in Changsha at about 10:42 local and at the door by 12:57 the same day.
Working backwards from a six in the evening handover in Changsha, the last useful departure from Chengdu is around 14:03 local.
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. 17 of them join CTU to CSX.
| Connecting at | CTU to hub, flights a day | Hub to CSX, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Nanning NNG | 1.43 | 1.71 | 1,781 | 4h 16m |
| Kunming KMG | 9.71 | 14.29 | 1,695 | 4h 33m |
| Guangzhou CAN | 23.43 | 3.71 | 1,756 | 4h 36m |
| Nanjing NKG | 12.29 | 4.71 | 2,096 | 4h 48m |
| Xiamen XMN | 6.86 | 8.71 | 2,184 | 4h 55m |
| Hong Kong HKG | 5.29 | 1.14 | 2,010 | 4h 57m |
With 10.4 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.
17 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Nanning NNG, where the weaker of the two legs still runs about once a day.
Through NNG the routing covers 1,781 km against the 937 km nonstop track and takes about 4h 16m in the air and on the ground at the hub, allowing 60 minutes to connect at an airport of that size.
That is 2h 34m more than the nonstop, which is the price of a missed departure on this pair.
Behind it, Kunming KMG at 4h 33m and Guangzhou CAN at 4h 36m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
If nothing suitable leaves Chengdu, Chengdu TFU is 56 km away by great circle and carries 173 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 CTU to CSX 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.
