Korean Air permits dogs, cats and pet birds aged eight weeks or older. Cabin transport is restricted to 7kg total including the carrier. The standard carrier dimensions are 32 × 45 × 19cm, although a soft carrier may be up to 25cm high if it compresses to 19cm. Once your ticket is purchased, apply for pet transportation at least 24 hours before a domestic departure or 48 hours before an international flight. A pet cannot travel without advance transport approval. Checked carriage has separate conditions, including an animal age of at least 16 weeks and a 45kg limit including the carrier, with breed, aircraft and temperature restrictions. A designated cabin seat may also be needed because some premium-seat layouts cannot store a carrier underneath. Confirm approval and destination quarantine requirements before travel.
