Families departing from Jeju Airport should distinguish where to use a nursing room from where to return a borrowed stroller. The operator says baby/maternity lounges serve children up to 36 months and pregnant travelers from 06:00 to 23:00. Domestic locations include left of departure B on floor 3, left of the Dollang Dollang Café on floor 1, and post-security areas near boarding gates 9 and 3 on floor 2. Facilities may include a changing table, sink, nursing area, microwave and drinking water. Stroller loans are handled at the central information desk on floor 3 with an ID deposit; they must be returned before security screening. The airport clinic is near gate 5 on floor 1 (064-797-2595) and a pharmacy is near gate 2 on floor 3. Priority security is listed for pregnant passengers and those with infants under 18 months; strollers still require X-ray screening. Check actual desk and clinic hours before departure.
