Air China measures the checked baggage by two methods. The first one is a weight concept which is used for all location excluding USA, Canada and Brazil. Applying this method means that the passengers are allowed to check an exact weight of baggage without additional payment. This free weight limitation for luggage is 20kg for Economy class, 30kg for Business class and 40kg for the First class.
The second method to calculate checked baggage is piece concept, which is used for departure and arrival flights in North America or Brazil. Applying this policy means that the passengers in all classes can only carry two pieces of free checked luggage with the sum of dimensions less than 158cm each piece. However, the maximum weights for each piece for Economy class are 23 kg, and these numbers for other classes are 32 kg. If you possess a membership card with Air China, you might carry more extra baggage in addition to the baggage allowance above.
