Air Busan Pet Policy
Official contract mentions pets; current transport mode and limits remain unconfirmed.
Official carriage terms accept accompanied small dogs/cats as baggage, in a container at handover and throughout flight, charged for pet plus container outside the free allowance. This clause does not specify cabin versus hold, current weight limits, routes or booking windows; those require confirmation.
Rules depend on the route, animal and operating carrier. Confirm your own journey with the relevant authority and airline.
