what are the rules for checked bags
To avoid causing injuries to porters, your checked baggage cannot exceed 32 kg (70lb) per piece, especially for passengers traveling to and from Australia, New Zealand, South Africa, Sri Lanka, UAE, and the United Kingdom. This is in accordance with the local occupational safety rules. If your checked baggage exceeds 32 kg per piece, you will be requested to repack. For some special items exceed 32 kg per piece, please contact China Airlines Reservation offices to pre-advise and get approval at least 24 hours prior to flight departure.
