All passengers are allowed to bring one item of cabin baggage onto the plane as well as one small item. The main item should be no larger than 56 cm x 36 cm x 23 cm, which includes any extra parts like the handles or wheels. You should also be able to fit it into the overhead compartments yourself. The smaller item is usually something like a handbag, laptop, camera bag or small briefcase, and this should be tucked under the chair in front of you. The dimensions of this item cannot exceed 15 cm x 30 cm x 40 cm.
The Cathay Pacific hand luggage allowance is also different depending on which class fare you have purchased. For Economy and Premium Economy the weight of both items of luggage may not exceed 7 kg. For Business Class this is increased to 10 kg, and for First Class they may add up to 15 kg. If you are travelling with an infant, you are also allowed a fold-up stroller, an approved car safety seat, and a bag containing sufficient food and nappies for the journey. Please also note that any duty-free products should be included as part of your baggage allowance and cannot be brought on to the plane separately.
Airlines are subject to restrictions for passengers wanting to transport liquids in their cabin baggage, and this extends to gels and aerosols as well. Ideally, liquids should be placed in the hold, but if you have to take liquids onboard they can only be accepted in bottles of 100ml or smaller. These bottles should be placed in a clear, re-sealable plastic bag which has to be fastened securely when closed. This plastic bag must be 20 cm x 20 cm or smaller, and security will need to see it separately from your bags when you are at the airport.
