Official baggage policy
How to use this policy

Check cabin bag dimensions, weight and personal-item limits separately. A bag has to pass every published limit at once; being under the length and width limit does not help if the depth, weight, or fare-specific allowance is tighter.

Editorial signal only. Leave margin instead of relying on discretionary gate behavior.

HK Express liquids policy

HK Express guidance: containers up to 100 ml in one transparent resealable bag up to 1 litre. Baby food/milk and liquid medicine have conditions; check all departure/transfer screening.
