This page goes deeper on one part of the policy. The full record is at China Southern Airlines Baggage Rules.

China Southern checked baggage on US routes is two pieces at 23 kg in Economy, two at 32 kg in Business and three at 32 kg in First. Every piece is capped at 62 in, or 158 cm, in total dimensions.

Two free bags beats most transpacific carriers. The excess charges are steep enough to make staying inside it worthwhile.

The China Southern Airlines record prints the allowance and the headline fees. This page is the hold in detail. The allowance by cabin and route, the excess bands in USD, how the charges stack, and what stays out of the hold.

China Southern checked baggage allowance by cabin

China Southern uses the piece concept on flights between China and the United States. The count and the weight both depend on cabin.

CabinUS routesDomestic China
Economy2 pieces at 23 kg each20 kg total
Premium Economy2 pieces at 23 kg each20 kg total
Business2 pieces at 32 kg each30 kg total
First3 pieces at 32 kg each40 kg total

The domestic column matters for anyone connecting onward inside China on a separate ticket. Domestic China flights use a weight concept, not pieces. Two 23 kg bags that flew free from Los Angeles to Guangzhou are 26 kg over on a separate domestic ticket.

On a single through ticket the international allowance carries across the domestic leg. That is the strongest reason to book the whole itinerary together rather than adding a domestic hop separately.

Size: 158 cm on every piece

Each bag on US routes may total 62 in, 158 cm, in length plus width plus height. Wheels and handles are part of the measurement. The general checked baggage weight limit guide explains why 23 kg and 158 cm are the near universal pair.

A bag from 159 to 203 cm is accepted as oversize for a fee. Beyond 203 cm it is not baggage. Plan on the 158 cm line, because the oversize charge is USD 165 per piece.

What excess costs on US routes

China Southern’s excess baggage page prints USD figures for its Americas zone. These are per piece, per direction.

ExcessFee
First extra piece, up to 23 kg and 158 cmUSD 225
Each additional piece after thatUSD 330
Overweight, 23 to 28 kgUSD 85
Overweight, 28 to 32 kgUSD 170
Overweight, 32 to 45 kgUSD 495
Oversize, 159 to 203 cmUSD 165

The charges are cumulative. China Southern states that a bag over two or more of the limits is charged for each. A third Economy bag at 30 kg and 170 cm pays USD 225 plus USD 170 plus USD 165.

The overweight bands are split at 28 kg, which is unusual. A 27 kg bag costs USD 85; a 29 kg bag costs double. The China Southern fees guide compares these with the carrier’s rivals, and the baggage cost calculator totals them for a trip.

The 32 kg and 45 kg lines

China Southern will accept a single piece up to 45 kg with the USD 495 charge paid. That is a rare allowance; most carriers refuse anything above 32 kg. But at USD 495 the fee is more than two extra pieces, so splitting the load is nearly always cheaper.

The guide to overweight and oversize baggage fees lays out how these bands compare across airlines. On China Southern the arithmetic is simple. Under 23 kg is free, 28 kg is the cheap ceiling, and 32 kg is the expensive one.

What cannot go in the hold

Power banks and spare lithium batteries never go in China Southern checked baggage. They travel in the cabin, and Chinese airports enforce this at the X-ray with more consistency than most. Electronic cigarettes go in the cabin as well.

The site’s page on power banks on a plane covers the watt-hour thresholds. China Southern also weighs cabin bags. The usual move of shifting weight into the carry-on has an 8 kg ceiling here.

Connections and partner tickets

China Southern is no longer a SkyTeam member but still interlines widely. On a ticket issued by another airline, that airline’s allowance governs the whole journey. On a China Southern ticket with a partner segment, the allowance on the confirmation is the one to trust.

For a US itinerary on linked tickets, the DOT most significant carrier rule decides whose baggage rules apply. Separate tickets mean separate allowances and a bag you collect and check in again.

Packing to two pieces at 23 kg

With two free pieces, the goal is two light cases rather than one heavy one. The Travelpro Maxlite 5 25 inch is the usual choice for the 23 kg allowance. Customer reviews commonly mention how little of it the empty case uses.

The Samsonite Omni PC 24 inch is the hardside option at a size well inside 158 cm. Owners note that a full 24 inch hardside lands closer to 23 kg than they expect. The second piece is where the heavy items go.

An Etekcity digital luggage scale is the cheapest way to avoid the 28 kg jump. Weigh both bags at home and move weight between them until each is under 23.

The bottom line

China Southern checked baggage on US routes is generous. Two 23 kg bags in Economy, two 32 kg bags in Business, three in First, each within 158 cm. Book the domestic connection on the same ticket so the allowance carries through.

Excess is expensive and cumulative. A third piece is USD 225.

Overweight starts at USD 85 and doubles at 28 kg, and oversize is USD 165. Two light cases under 23 kg each beat every one of those numbers.

Common questions

How many checked bags does China Southern allow on US flights?

Two pieces at 23 kg each in Economy and Premium Economy, two at 32 kg each in Business, and three at 32 kg each in First, each within 158 cm in total dimensions.

What is the China Southern checked baggage weight limit?

23 kg per piece in Economy and 32 kg in Business and First on US routes. Overweight bags are accepted for a fee up to 45 kg, but the charge for 32 to 45 kg is USD 495.

How much is an extra checked bag on China Southern?

USD 225 for the first piece beyond the free allowance and USD 330 for each additional piece on flights between China and the Americas, per direction.

What does China Southern charge for overweight baggage?

USD 85 for a bag between 23 and 28 kg, USD 170 for 28 to 32 kg, and USD 495 for 32 to 45 kg, per piece, on US routes. The charges stack with any oversize or extra piece fee.

Does my China Southern international allowance apply on a domestic Chinese connection?

Only on a single through ticket. Domestic China flights use a 20 kg weight allowance in Economy, so two 23 kg bags on a separate domestic ticket would be overweight.

Can I put a power bank in checked baggage on China Southern?

No. Power banks and spare lithium batteries must travel in the cabin, and Chinese airports enforce that rule strictly at security.
