Allowance for carry-on luggage and checked luggage will vary with the class of your airline ticket, the dimensions of the bag, and individual airline policies. Usually, for domestic China and Intra-asia flights, you are allowed to check one piece of luggage. The limitation is 20 Kilograms (44 pounds) total. A fee may be imposed for excess weight. Passengers traveling together can have their luggage allowances calculated together on a per-person basis. There is no free luggage allowance for holders of infant tickets. Passengers may apply for insurance coverage above the minimum value for checked luggage. On domestic trains there are no luggage restrictions, but few porters are available to help with luggage. Travelers who are not part of an organized tour will be responsible for carrying their own bags.
