'I lost my bag at Incheon Airport' can mean two very different problems. A checked suitcase missing from the baggage belt is handled by your airline. A handbag left in a public terminal area belongs in the airport's lost-property process. Start with where you last had the item; that determines the right desk and saves time.
- Find last known location
- Checked bag → airline
- Terminal item → Lost and Found
- Save report reference

If a checked bag does not appear
Stay in the baggage-claim area and find your airline's lost-baggage service counter near the carousels. Show your baggage tag, boarding pass, flight number, contact address and a description of the bag. Ask for a written case or reference number and the airline's update channel before leaving. For damage, report it immediately there as well.
Incheon Airport states that airlines manage checked-baggage records and their own compensation policies. The airport lost-and-found office cannot trace a suitcase that the airline accepted for carriage. If you have already left the airport, contact the airline directly and preserve receipts for essential replacement items according to its claims rules.
If you misplaced an item instead
For something left in the public terminal, transport centre, curbside or car park, use Incheon Airport Lost and Found. An item left on a plane belongs with the airline's cabin lost-property process. An item in a security-controlled or duty-free area can involve a different authority; the airport's official lost-item table identifies the right contact. Items on an airport bus or train go to that operator.
Give the exact terminal, last location, approximate time and identifying details, but do not post passport or card numbers publicly. Check the current contact number and location on the airport page rather than an old screenshot.
A sentence to show staff
For checked baggage say '위탁수하물이 안 나왔어요. 항공사 수하물 카운터가 어디인가요?' ('My checked bag did not arrive. Where is my airline's baggage desk?'). For an item left in the building say '공항 안에서 물건을 잃어버렸어요. 분실물 센터가 어디인가요?' ('I lost an item in the airport. Where is Lost and Found?').
Write down who received your report, the reference number and what happens next. Never surrender your only copy of the baggage tag without making a photo.
A worked example
Your suitcase was checked at your departure airport and never reaches the Incheon carousel: report it to the airline before leaving arrivals. If the suitcase arrived but you later forgot a smaller bag by an airport café in a public area, contact the airport Lost and Found instead. The same word 'lost' leads to different agencies.
