Carry-on Baggage

Notes to Passengers

For the safety of all passengers and our crew, please put your carry-on baggage in the rack above your seat or under the seat in front of you. Passengers seated near emergency exits (including those seated near wing exits and in the first row) must put their baggage in the overhead rack to ensure that the baggage will not hinder evacuation in case of emergency.

We will check your carry-on baggage when you go through check-in formalities and before boarding. You must check in your overweight carry-on baggage when going through check-in formalities. Before boarding, overweight carry-on baggage must be put in the baggage compartment. If the total weight of the carry-on baggage and the checked baggage exceeds the prescribed amount, you will need to pay excess baggage charges.

CSAir has the right to determine at our discretion whether your baggage should be treated as carry-on baggage or checked baggage to ensure your safety and comfort as well as the safety and comfort of other passengers.
