Baggage fees
No reliable fixed price is listed here. Check your booking for the cost of adding a bag; an unlisted price does not mean it is free.
Official baggage policyHow 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. Measure the packed bag and verify the operating carrier's rule.
Cathay Pacific liquids policy
Confirm airport screening and Cathay restricted-item conditions for liquids. Spare batteries are not permitted in checked baggage. Power banks must not be used or recharged in flight or stored in overhead compartments; check current battery quantity/capacity conditions.
Family & Infants
Infant (under 2)
Infant without an own seat must remain under 24 months throughout the journey; minimum age 7 days. Fare discount depends on the selected adult fare, not a universal 10%.

Car seat
One approved child restraint is listed as additional cabin equipment; arrange seating, approval and aircraft compatibility. Infant checked entitlement includes a car safety seat plus stroller; free carriage is not automatic permission for cabin use.
