Air China Baggage Allowance: Cabin Bags & Fees
Flying with Air China? Check cabin bag size and weight, UK-route checked baggage allowances, liquids and excess baggage rules before you travel.
Air China's baggage rules vary by travel class and route. On international services, Economy and Premium Economy passengers may generally bring one cabin bag, while Business and First Class passengers may bring two. Cabin bags can measure up to 55 × 40 × 20cm.
Cabin baggage is one of the first things to check before travelling with Air China, because the number of pieces, permitted size and weight can differ by fare or travel class. The current allowance is summarised as follows: Economy / Premium Economy 1 × 55 × 40 × 20cm Max 5kg Business / First 2 pieces, max 8kg each. Your smaller personal item, where permitted, should be suitable for stowage beneath the seat, while the main cabin bag must fit safely in the overhead locker.
Checked baggage with Air China also depends on the ticket you have purchased rather than simply the destination. The current headline allowance is: UK routes Economy: 1 × 23kg Premium Economy: 2 × 23kg Business / First: 2 × 32kg Max 158cm per free piece. Lower-cost or light fares can exclude checked baggage altogether, while flexible and premium fares often provide a larger allowance. Always check the baggage entitlement attached to the individual booking before packing.
Size and weight are separate limits. A suitcase can be within the permitted dimensions but still be overweight, or it can be light enough while exceeding the airline's dimensional limit. Overweight / oversized baggage costs extra International bags normally max 32kg each Free piece max 158cm. Additional, overweight or oversized baggage can therefore attract extra charges or different handling requirements.
Cabin baggage must also comply with airport-security and dangerous-goods rules, which are separate from Air China's own baggage allowance. Liquids, gels, pastes and aerosols may be subject to the familiar 100ml container restrictions depending on the departure and connecting airports, while power banks and spare lithium batteries normally need to remain in cabin baggage rather than being packed in the hold.
This guide explains Air China's cabin and personal-item rules, checked-baggage allowances, fare and travel-class differences, liquid restrictions, additional and excess baggage, and the practical points most likely to cause problems at the airport. If another airline operates part of your journey, check that carrier's rules as well because allowances can differ across a multi-airline itinerary.

Key Air China Baggage Tips
Economy and Premium Economy passengers may bring 1 cabin bag; Business and First Class passengers may bring 2.
Economy and Premium Economy cabin bags are limited to 5kg per piece.
Business and First Class cabin bags are limited to 8kg per piece.
Check the allowance on your Air China booking before you pack. Fare, cabin and route differences can materially change what is included.
Measure bags externally, including wheels, handles and protruding pockets, rather than relying only on the manufacturer's stated suitcase size.
Weigh cabin and checked baggage at home. A bag can be within the size limit but still attract charges if it exceeds the permitted weight.
Keep the personal item genuinely small enough to fit beneath the seat if the airline requires under-seat stowage; do not treat it as a second full-size cabin bag.
If you already know you need extra checked baggage, add it before reaching the airport where the airline offers advance purchase; airport excess-baggage charges can be higher.
Where standard airport liquid rules apply, the container size matters: a partly used bottle larger than 100ml can still be rejected at security.
Pack full-size toiletries in checked baggage when appropriate, while keeping medication and anything needed during the journey accessible in the cabin.
Keep power banks and spare lithium batteries in cabin baggage, protected against short circuits, rather than placing them in the hold.

Checked baggage with Air China: what you need to know
For Air China-operated routes between the United Kingdom and China, current free checked-baggage allowances are generally 1 × 23kg in Economy, 2 × 23kg in Premium Economy and 2 × 32kg in Business or First Class.
Each free checked bag on international and regional routes must normally stay within 158cm total linear dimensions, including wheels and handles. Air China may accept larger checked baggage up to 203cm subject to excess-baggage charges, but ordinary checked bags on international services normally cannot exceed 32kg per piece.
Codeshare or connecting journeys can be governed by another carrier's baggage rules, so confirm the operating airline and the allowance printed on your ticket.
Air China's checked-baggage entitlement can depend on the fare, travel class, route and the airline operating each sector. The allowance shown on your ticket or booking confirmation should therefore be treated as the final reference.
If your included allowance is not enough, additional baggage can usually be added where the airline offers this service. Arranging extra baggage before travel is generally preferable to discovering an excess at check-in.
A bag that exceeds the permitted weight, dimensions or number of pieces can be treated as excess, overweight or oversized baggage. Separate charges or handling restrictions may apply, and very heavy items may need to be repacked or carried as cargo.
Before travelling, check the baggage allowance attached to your specific Air China booking, particularly if you have changed your ticket, upgraded your cabin or added a connecting flight.
Air China cabin baggage rules: liquids, extras and restrictions
Air China limits each cabin bag to 55 × 40 × 20cm. Economy and Premium Economy passengers may carry one piece weighing up to 5kg; Business and First Class passengers may carry two pieces weighing up to 8kg each.
One additional small personal item such as a handbag, briefcase or laptop bag may also be carried if it fits beneath the seat in front.
If your itinerary includes a mainland-China domestic sector, be aware that liquid rules differ from those for international flights. Air China states that liquids are generally prohibited in carry-on baggage on domestic flights, subject to limited exceptions such as small quantities of cosmetics in containers up to 100ml.
Cabin baggage must be small and light enough to be safely stowed in the overhead locker or, for a personal item, beneath the seat in front. Published measurements normally include wheels, handles and other protruding parts unless the airline explicitly states otherwise.
Typical products affected include toothpaste, deodorant, shampoo, conditioner, shower gel, sun cream, skincare and cosmetics. Medication, baby food and certain medical items can qualify for security exemptions when required for the journey, although supporting evidence may be requested.
Power banks and spare lithium batteries should be carried in cabin baggage rather than checked baggage and protected against short circuits. Other dangerous or restricted items can be prohibited entirely or limited to either cabin or checked baggage.
Air China staff or airport handling agents may check cabin baggage at check-in or the gate. A bag that exceeds the permitted number, size or weight can be placed in the hold and additional charges may apply.
