Air Busan's official infant-travel page says infants may fly from seven days after birth on domestic routes and from 14 days on international routes. A child advised against flying for medical reasons may need separate medical assessment. Infants do not receive a separate seat, and each accompanying adult can travel with one infant. Domestic infant fares are free, whereas international infant fares vary by route and departure airport. Strollers and infant car seats have separate rules under the airline's baggage policy. Enter the infant's date of birth correctly when booking because infant and child categories differ.
