Air Busan's official restricted-items guide says liquids carried onto international flights departing or connecting in Korea generally must be in containers of 100 mL or less, all inside one transparent resealable bag of no more than 1 L per passenger. Check the container's labelled capacity even if it holds little liquid. Reasonable amounts of necessary medicine, infant milk and baby food, or medically required liquids may be permitted under separate exceptions. The same international liquid restriction is not applied to domestic routes, although dangerous-goods rules still apply. Duty-free liquids may require a tamper-evident sealed bag, and restrictions at connecting airports can differ.
