The Cathay Pacific pet policy is as follows:
Pets are not accepted in the aircraft cabin.
Most pets can travel as check-in baggage on Cathay Pacific flights out of Hong Kong. Your destination, however, may have different animal transport guidelines – please contact your local reservations office to confirm your pet can be accepted as check-in baggage.
When you fly into Hong Kong, your pet will need to travel in cargo. Please contact your local Cathay Pacific Cargo office for more information and assistance.
Brachycephalic (snub-nosed, short snout or flat face) animals are not accepted as check-in baggage or for cargo carriage.
Taking a pet to a foreign country involves preparation and planning far in advance of your departure date. Requirements for pet travel to a foreign country are set by the destination country. If you are you traveling to another country and bringing along your pet you’ll need to meet the animal health requirements of the country you are visiting.
