China Southern Airlines in the network the desk measures
Computed on 2026-09-07 from AeroDataBox scheduled route statistics. The desk holds departure schedules for 571 airports, and for the CZ code that yields 546 city pairs across 198 of them. It is a measured sample of the published timetable and not the whole of it. Frequencies move with the season, and a quote is priced on the flights running the day you ask.

The schedule the desk holds carries the CZ code on 546 city pairs, reaching 198 airports in 45 countries and territories. Some of those sectors are flown by China Southern Airlines and some are sold under its code and flown by a partner, which is how the published timetable states it and how a booking has to be read. 84.8 per cent of those airports sit on Asian time zones, and the next largest block is on European time zones.
01The longest sector held for the carrier is Mexico City (MEX) to Shenzhen (SZX) at about 14,130 km, and the shortest is Korla (KRL) to Ürümqi (URC) at about 269 km. 44 of the 546 pairs run past 5,000 km, so the carrier carries a courier across a continent on some sectors and shuttles on the rest. The airport that appears most often on those pairs is Guangzhou (CAN), on 151 of them, which is 27.7 per cent of everything held under this code.
02The thickest sector under the code is Shanghai (SHA) to Shenzhen (SZX) at about 46.1 movements a day, which across a full day is roughly one every 0.5 hours. On a sector at that cadence a missed departure costs a wait rather than a night. That sector does not touch Guangzhou (CAN), the airport this code is booked through most often, so the desk treats it as a seat sold under the code rather than flown by the carrier, and confirms the operating airline before it quotes. 271 of the 546 pairs run four or more times a day and 95 run once a day or less. The second figure is the one that matters when a consignment leaves the factory late, because on those sectors the desk will quote a different carrier rather than promise an hour it cannot hold. After Guangzhou (CAN) the code leans on Shenzhen (SZX) on 63, Beijing (PKX) on 62, Ürümqi (URC) on 56 pairs respectively, and those are the airports a dispatcher looks at second when the first routing is full.
The sectors that carry the CZ code most often
The 16 sectors the CZ code appears on most often, out of 546. Flights a day is the average daily scheduled movement on the busier of the two directions, as held on 2026-09-07. The schedule lists a code against a sector whether the carrier operates it or sells it, so read this as where the code can be booked. Distances are great circle, computed from the published coordinates of the two airports.
Where CZ meets the UAE gateways
China Southern Airlines is one of the carriers a courier can board without leaving the Emirates. The desk holds 1 pairs under this code touching Dubai (DXB), so a booking can start at a UAE counter and stay on one ticket to the delivery city.
Night restrictions on the airports the CZ code uses
A hand carry is bought for the hours it saves, and an airport that will not take a movement after a certain hour can spend those hours back. 17 of the 198 airports this code is booked through carry a restriction the desk holds in writing, checked 2026-09-07. Exemptions and seasonal variations exist, and the desk confirms the position with the airport or the carrier before it books.
- Shanghai (PVG), night operations. Operates around the clock.
- Seoul (ICN), night operations. Operates around the clock.
- Tokyo (NRT), night restrictions. Scheduled movements are limited between 23:00 and 06:00 local; late departures usually route through Haneda instead.
- Taipei (TPE), night operations. Operates around the clock.
- Frankfurt-am-Main (FRA), night restrictions. No scheduled take offs or landings between 23:00 and 05:00 local. A late evening departure that slips past 23:00 does not go until morning.
- London (LHR), night restrictions. A night quota system limits movements between 23:30 and 06:00 local. Very few scheduled departures in that window.
Published lanes that carry the CZ code
The site publishes a page for 346 courier lanes. China Southern Airlines appears in the schedule on 3 of them, and the one it flies most is Seoul to Shanghai at about 22.4 movements a day. That overlap is the honest test of whether a carrier is useful to this desk rather than merely famous.
The countries the CZ code opens
Of the 45 countries and territories reached, 27 are reached at a single airport, which for a courier means one airport of entry and a road leg for everything else in that country. The deepest is China with 122 airports on this code. The country desk for China sets out the customs practice, the working hours and the road legs behind these airports.
China (122 airports), Australia (6 airports), United States (5 airports), Indonesia (5 airports), Vietnam (3 airports), Thailand (3 airports), South Korea (3 airports), Japan (3 airports), Malaysia (3 airports), Cambodia (2 airports).
