What ORD to SZX looks like
The ORD to SZX sector, the carriers on it and the flying time, before anything is promised to anybody.
Chicago ORD to Shenzhen SZX is an ultra long sector of 12,491 km by great circle, flown nonstop about once a day.
Chicago ORD is a major hub in the network held here, 295 scheduled destinations and 1,461 departures a day. Shenzhen SZX has 157 destinations and 574.7 departures a day.
Chicago carries about 2.5 times the departures of Shenzhen, so a courier who has to be rebooked has far more to work with at one end of this pair than at the other.
Shenzhen runs 14 hours ahead of Chicago in January and 13 hours ahead in July, because the two ends do not change their clocks together.
The pair sits between the Americas and 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 ORD to SZX from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| ORD to SZX | 1.43 | 10 | none held |
| SZX to ORD | 0 | 0 | none held |
No operating carrier is recorded on the nonstop, which is why the connecting routings below are the plan for ORD to SZX rather than the fallback.
The return leg SZX to ORD carries no scheduled nonstop at all, so a courier coming back does it with a connection.
Between them the two directions put about 10 departures a week on ORD to SZX, 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 15h 33m block time on ORD to SZX. Change any of them in the tool further down and the total moves with them.
| Stage | Allowed | Elapsed |
|---|---|---|
| Collection and the run to ORD | 90 min | 1h 30m |
| At ORD before departure | 180 min | 4h 30m |
| ORD to SZX in the air, estimated | 933 min | 20h 03m |
| Formalities at SZX | 90 min | 21h 33m |
| Delivery run in Shenzhen | 45 min | 22h 18m |
| Door to door | 1,338 min | 22h 18m |
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 ORD to SZX is 22h 18m.
A courier who leaves Chicago at 09:00 local is on the ground in Shenzhen at about 14:33 local and at the door by 16:48 the following day.
Working backwards from a six in the evening handover in Shenzhen, nothing leaving Chicago inside a normal working day arrives in time, so this pair is an overnight and a next morning delivery rather than a same day one.
At 22h 18m the mission is past the sixteen hour duty day a single courier is planned against, so it is quoted with a rest at the far end or with a second courier, and never as a turnaround.
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. 20 of them join ORD to SZX.
| Connecting at | ORD to hub, flights a day | Hub to SZX, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Nanjing NKG | 0.71 | 19.14 | 12,500 | 17h 08m |
| Seoul ICN | 4.71 | 6.29 | 12,564 | 17h 32m |
| Taipei TPE | 1.71 | 4.29 | 12,782 | 17h 42m |
| Shanghai PVG | 2.57 | 17.71 | 12,567 | 17h 43m |
| Osaka KIX | 0.86 | 1 | 12,911 | 17h 44m |
| Tokyo HND | 1.14 | 1.14 | 13,014 | 18h 08m |
One nonstop a day means one chance a day, so the connections below are what a consignment that arrives at ORD in the afternoon actually flies on.
20 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 5 times a week.
Through NKG the routing covers 12,500 km against the 12,491 km nonstop track and takes about 17h 08m 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 35m 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 17h 32m and Taipei TPE at 17h 42m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
If nothing suitable leaves Chicago, Chicago MDW is 25 km away by great circle and carries 208 scheduled destinations of its own, which is usually a shorter road transfer than a lost day.
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 ORD 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.
