Shenzhen Airlines caps economy carry-on bags at 5 kilograms, about 11 pounds. That is one of the lowest cabin weight limits this site tracks. It drives most of the Shenzhen Airlines baggage allowance, and it catches travelers used to looser US rules.
The size limit is roomier by comparison. One bag can measure up to 55 by 40 by 20 centimeters, or about 22 by 16 by 8 inches. Weight, not size, is where economy passengers get caught out.
Business and First Class travelers get a second carry-on piece. They also get a free personal item, such as a laptop bag or handbag, under the seat. Here the airline’s own English pages disagree with each other.
The dedicated carry-on baggage page lists 8 kilograms per piece for Business. The airline’s international conditions of carriage instead cap every cabin at 5 kilograms. Confirm your fare’s cabin before you assume the higher figure applies.
Checked baggage splits along a border most flyers do not expect
The Shenzhen Airlines baggage allowance is not one rule. It is two, and which one applies depends on whether the flight crosses a border. Domestic China routes set a free allowance by cabin class.
First gets 40 kilograms, Business gets 30, and Economy gets 20. Each bag is capped at 100 by 60 by 40 centimeters and 32 kilograms.
International and regional flights count pieces instead of total weight. Economy gets one bag up to 23 kilograms, or 50 pounds, on most routes. Flights to Japan get two bags instead of one.
First and Business passengers on international routes get two bags each, up to 32 kilograms per bag.
| Route type | Economy checked allowance | Size limit per bag |
|---|---|---|
| Domestic China | 1 bag, 20 kg, 100x60x40 cm | 32 kg max per piece |
| International, most routes | 1 bag, 23 kg / 50 lb | Sum of sides under 203 cm / 80 in |
| International, Japan routes | 2 bags, 23 kg / 50 lb each | Sum of sides under 203 cm / 80 in |
What an extra or oversized bag actually costs
On international and regional routes, Shenzhen Airlines prices extra bags per piece, not per kilogram. A first additional piece runs about 700 RMB, roughly 110 USD. A second piece runs about 1,000 RMB, close to 155 USD.
A bag that only breaks the weight or size limit, without adding a whole extra piece, costs around 490 RMB, about 75 USD. Break both limits at once and the fee rises to about 700 RMB, near 110 USD. Domestic routes charge per kilogram over the limit instead, at a rate tied to the standard nonstop Economy fare.
The Air China connection shows up in the fine print
Shenzhen Airlines is majority owned by Air China Group. It still flies under its own brand and its own IATA code, ZH.
This page covers Shenzhen Airlines on its own terms, not folded into Air China baggage rules. The ownership link is not just corporate trivia, either.
Elite members of Air China’s PhoenixMiles program get one extra checked piece on Shenzhen Airlines flights. So do Star Alliance Gold members, even though Shenzhen Airlines itself does not belong to Star Alliance.
What travelers actually report
Community discussion of the Shenzhen Airlines baggage allowance is thin next to bigger Chinese carriers. A FlyerTalk thread comparing it against China Southern baggage allowance policy blocked automated reading when this page was checked. The search snippets that survived carried only the thread title, not the substance, so that comparison stays unconfirmed here.
One pattern from traveler reviews is verifiable: smoother interline handling than the rules alone suggest. Checked bags on connecting itineraries have arrived through to the final stop without a recheck in Shenzhen.
Passengers carrying dive gear or camera gear with lithium batteries also report closer inspection at the security checkpoint, not at the bag drop. That lines up with standard battery rules rather than anything specific to this airline.
How Shenzhen Airlines compares to its sister carriers
Travelers connecting within China often end up comparing Shenzhen Airlines against China Eastern, Hainan Airlines or Sichuan Airlines. Each carrier publishes its own figures. Do not assume Shenzhen Airlines numbers carry over to a connecting flight, even one within the same ownership group.

The bottom line
The Shenzhen Airlines baggage allowance rewards travelers who check the size first and the weight second. That 5 kilogram economy carry-on cap is stricter than the roomy box dimensions suggest. Checked baggage depends entirely on whether the flight crosses a border.
Domestic trips use a straight allowance by cabin class. International trips count pieces instead. Confirm the exact rule against your own itinerary at checked baggage before you pack, since exceptions by fare type are common on this route network.
