China Southern Airlines Carry-on Luggage Rules
China Southern Airlines allows passengers one piece of carry-on baggage. The size limit for carry-on luggage is 55.0 × 40.0 × 20.0 cm (approx 21.5 × 15.5 × 7.5 in) and the maximum weight is 8.0 kg (17 lb). First-class passengers may be allowed two carry-on bags, subject to the same size and weight restrictions per bag.
In addition to your carry-on baggage allowance, China Southern Airlines permits one personal item, such as a small handbag, briefcase, camera bag, or laptop bag. These items must fit under the seat in front of you. Note that China Southern Airlines reserves the right to determine if your carry-on luggage needs to be checked due to space limitations or if it exceeds size/weight limits.
