First/Business Class: 2 checked bags at 32kg (70lb) each on international routes. Premium Economy/Economy: 1 checked bag at 23kg (50lb). Domestic China flights use a flat per-cabin weight allowance instead: 40kg First, 30kg Business, 20kg Premium Economy/Economy. Carry-on size limit not published on Air China own channels as of Sep 2026.
This page goes deeper on one part of the policy. The full record is at Air China Baggage Rules.
The Air China checked baggage allowance runs on weight, not a piece count, on every international route. Economy and Premium Economy get 23 kg (50 lb) per bag. Business and First get 32 kg (70 lb).
Air China states the international numbers plainly on its own baggage page. The allowance stays the same whether a flight starts in Beijing, Chengdu or a US gateway city. First and Business passengers get two free bags at 32 kg each on international sectors.
Premium Economy and Economy get one free bag at 23 kg. Anything heavier than 32 kg cannot travel as checked baggage at all. Air China requires that weight to move as air cargo instead.
Domestic China flights run on a different scale
Once a routing touches an all domestic Chinese sector, Air China switches to a flat per cabin weight. The published domestic scale is 40 kg in First, 30 kg in Business and 20 kg in Premium Economy and Economy. That is lower than the international 23 kg Economy figure.
A traveler connecting onto a China domestic leg should check which allowance actually governs that segment. Packing to the international Air China checked baggage allowance and flying it domestically can mean an unexpected fee.
Size limits and the linear inch rule
Air China caps each checked bag at 158 cm (62 in) total for length, width and height combined. A bag under 60 cm (24 in) combined is treated as undersized.
A separate piece system allowance covers purchased excess baggage and allows up to 203 cm (80 in) per bag.
What cannot go in the hold
Air China routes spare lithium batteries and power banks to its dangerous goods policy rather than a checked bag. Keep those items in the cabin. Airlines worldwide treat an unattended lithium cell in the hold as a fire risk.
Surfboards, skis, canoes, javelins and paragliding gear need Air China’s prior approval before they can be checked. A musical instrument checked as baggage requires signing the carrier’s own risk notice at the counter. Air China will not guarantee an instrument against handling damage.
Firearms and ammunition follow the standard declaration process at check in. For anything the carrier’s English page leaves out, call the local Air China counter first. That beats guessing at the gate.
Connecting bags and the most significant carrier rule
On a ticket that mixes Air China with a codeshare or interline partner, one rule usually decides the allowance. The US Department of Transportation calls it the most significant carrier rule. It is explained on transportation.gov.
Air China’s own page states that it does not currently run interline baggage arrangements for pets with partner airlines. That is a useful signal on its own. Special or oversized items should never be assumed to transfer automatically on a mixed carrier trip.
Confirm the governing allowance with the ticketing carrier rather than assuming the Air China checked baggage allowance covers the whole itinerary.
Overweight and oversize fees
Air China’s site does not print a flat table of excess baggage charges by kilogram for international routes. It states that oversize and overweight charges are calculated together when a bag fails both limits at once. No fixed international schedule is attached to that statement.
What Air China does publish is a domestic add on. It sells fixed extra weight in steps of 5 kg, 10 kg, 15 kg or 20 kg per passenger per flight. Counters generally weigh every bag rather than eyeball it, so a bag a kilogram or two over 23 kg is worth repacking first.
The safest move on any Air China itinerary is weighing bags before leaving for the airport. A baggage fee calculator only helps once the actual weights are known. The site’s own checked baggage weight limit guide explains how carriers generally set these caps.
The Etekcity digital luggage scale answers the 23 kg question at home. That beats guessing at the Air China counter.
Bags that leave room under a 23 kg cap
Economy passengers are capped at 23 kg total, including the case itself. The empty weight of the suitcase matters almost as much as its size. A heavy 28 inch hardside can use several kilograms before a single item goes inside it.
| Bag | Size class | Why it suits a 23 kg cap |
|---|---|---|
| Travelpro Maxlite 5 25 inch expandable spinner | Medium checked | One of the lighter 25 inch cases sold, leaving more of the 23 kg for clothing. |
| Travelpro Maxlite 5 29 inch | Large checked | A light 29 inch case for the Business cabin 32 kg allowance, where the extra volume is usable. |
| Samsonite Omni PC 24 inch | Medium checked | A durable shell at 62 linear inches, well inside Air China’s 158 cm total. |
| Delsey Paris Helium Aero 24 inch checked spinner | Medium checked | An integrated lock on the shell for a single traveler’s week long trip. |
| Amazon Basics 30 inch hardside checked luggage | Large checked | Roomy and cheap, but its 30 inch size sits close to Air China’s 158 cm limit once packed. |
Reviewers of that lightweight Travelpro line commonly mention its low empty weight. That is the reason it survives international weight caps better than heavier bags. Samsonite’s Omni PC line draws similar comments for durability without adding much shell weight.
On paper, the Delsey Paris case above trades a little of that lightness for a lock built into the shell itself.

For the cabin side of an Air China trip, the airline’s main Air China baggage page covers what the carrier does and does not publish for carry on bags. Lithium battery placement gets a fuller answer on batteries in checked luggage.
The bottom line
The Air China checked baggage allowance is straightforward on international routes. Economy and Premium Economy get 23 kg. Business and First get 32 kg, and every bag is capped at 158 cm total.
The real complication is a domestic China connection. It runs on a lower flat weight per cabin instead of the international per bag figure. Weigh at home, keep batteries in the cabin, and confirm the governing allowance before checking a bag on a mixed carrier itinerary.
