Carry-on Baggage

1 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 inspect your carry-on baggage before check-in and boarding. Please do check your carry-on items that exceed the limits to weight, number of pieces or volume. If the baggage you carry exceeds the free baggage allowance, you will be required to pay excess baggage fee and place the baggage in aircraft’s cargo compartment. According to the Regulation on the Transport of Dangerous Goods by Air (Order No. 42 of the Ministry of Transport of the People's Republic of China, 2016), if your carry-on excess baggage doesn’t comply with relevant regulations, you must re-check the baggage at check-in counter or self-service baggage checking equipment, and such baggage may not arrive at the destination on the same flight with you.

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.
