Below are the Air China carry-on and checked baggage limits for standard economy. Promotional and basic fares are often stricter, so check the rules of your own ticket before you fly.
| Carry-on bag | 55 × 40 × 20 cm, up to 5 kg Economy and super economy: one piece of up to 5 kg. The size is the same in every class. |
| Personal item | allowed One personal item under the seat is allowed — a handbag, briefcase, laptop or camera bag. The site gives no dimensions. |
| Checked bag on the basic fare | 158 cm International and regional routes with the piece concept, Economy Standard: one piece of 23 kg. On domestic flights in China the weight concept applies, with 20 kg in economy. |
| Business Class | carry-on up to 8 kg, 2 pieces, checked bag up to 32 kg |

Cabin bag size is measured over the outside — wheels, handles and pockets included; the sizer at the gate makes no allowances.
Weight is checked at random, but staff can weigh your bag at check-in or at the gate. An overweight cabin bag usually ends up in the hold at the aircraft door, and that costs more than buying baggage in advance.
Liquids in the cabin go in containers of up to 100 ml inside one transparent one-litre bag. That is an airport rule rather than an airline one, and countries apply it differently.
