For China domestic flights, a first class adult ticket holder can take the luggage of 40 kg free of charge (checked and carry-on luggage); A business class adult ticket holder can take 30 kg free of charge (checked and carry-on luggage); An economy class adult ticket holder is allowed to bear 20 kg for free (checked and carry-on luggage).

The size of each carry-on luggage should be smaller than 20 X 40 X 55 centimeter and total weight should be less than 5 kg. Otherwise, the luggage should be checked together with your other luggage.

For your fragile and oversize telescopes, you can check them when handling the boarding procedure. The charge rate of the overweighted luggage for China domestic flights is 1.5% per kilogram, multiplied by the economy class ticket price. Each Chinese airline company has a different method and rate to charge the overweighted luggage to which passengers should pay attention.
