Hand baggage regulations
Passengers using Hong Kong International Airport are expected to follow the hand baggage guidelines set by the Airline Operators Committee. These state that hand baggage carried onboard an aircraft must not exceed 56cm x 36cm x 23 cm (22” x 14” x 9”).
You can check whether your baggage is the right size by using the measuring gauges found around the Check-in Hall and at the entrances of the Immigration Halls in Terminal 1 and Terminal 2. If you are uncertain, please check with your airline.
