Pets usually cannot share the same cabin with their owners for long-distance transportation and must be checked in, placing pets in designated oxygen cabins or compartments. Moreover, not every flight has a specific oxygen cabin for pets. Owners needing to check in pets must call in advance to understand the situation before deciding to purchase tickets. Pets traveling on large transport vehicles must have three certificates: an "Animal Health Immunization Certificate," a "Quarantine Certificate," and a "Transport Vehicle Disinfection Certificate." The animal health immunization certificate can be obtained at a regular veterinary hospital, while the other certificates are issued by the animal health supervision department.
