Baggage fees
No reliable fixed price is listed here. Check your booking for the cost of adding a bag; an unlisted price does not mean it is free.
Official baggage policyHow to use this policy
Check cabin bag dimensions, weight and personal-item limits separately. A bag has to pass every published limit at once; being under the length and width limit does not help if the depth, weight, or fare-specific allowance is tighter.
Editorial signal only. Measure the packed bag and verify the operating carrier's rule.
Korean Air liquids policy
Confirm departure/transit security limits and medicine/infant-food exemptions. Korean Air requires liquid duty-free purchases to remain sealed with a receipt in a STEB; transfer-country rules can still restrict them.
Family & Infants
Infant (under 2)
Infant allowance: domestic one foldable stroller/wagon plus one car seat/bassinet; international additionally one baggage item. Confirm the item weight and infant ticket rather than treating this as extra adult cabin baggage.
Stroller
A stroller over 115 cm total must be checked at the gate. International gate return and domestic baggage-claim return are described, but local airport conditions can prevent gate return.
Car seat
One car seat or bassinet is listed in infant baggage allowance. Onboard use needs the applicable child-seat arrangement and approval.
