Adult tickets and children's tickets can be carried free of charge: first-class passengers can carry 40KG, business class 30KG, economy class 20KG, and children's tickets are free 10KG. However, the maximum baggage circumference should not exceed 1 15CM, which is also the requirement of aviation boarding boxes.
Another way is to give away free luggage according to the number of pieces, but only on China-US and China-Canada routes. Two pieces of luggage can be checked for free in first class and business class, the circumference is less than 158CM, and the weight is less than 32KG. You can also check two pieces in economy class for free, and the circumference of each piece of luggage should not exceed 158CM, and the weight should be controlled within 23KG.
Adults with babies can check a piece of luggage for free if they pay 10%, and the sum of the same length, width and height cannot be greater than 1 15CM. In addition, you can also check in a folding stroller and a cradle for free. If these regulations are exceeded, it will be checked as paid baggage.
