United Airlines Lost and Found

Lost and Found

If you've lost an item during your United Airlines flight or at the airport, United Airlines is here to help. The Lost and Found service ensures you can easily report and recover your lost belongings. Follow these steps to report and recover your lost items.

Items Lost within the Airport

For items lost in public areas of the airport, such as restrooms, shops, security checkpoints, or the terminal building, please contact the airport's  Lost & Found centre. The general airport contact number for lost property queries is +81 72 455 2500.

Items Lost Onboard or at the Gate

If your item was left onboard a United flight, or in the boarding‑gate area, you should contact United Airlines' ground handling or baggage service team at Kansai Airport directly. Provide your flight number, date of travel, seat number and a clear description of the lost item.

The airline's staff at the check‑in or departure area may assist in tracing the item through the carrier's internal system.

Important Additional Information

When using the airport's lost‑property form: note that items lost more than 3 months ago may no longer be retrievable.

For items still within the airline's control (onboard, gate area), contacting United as soon as possible increases your chances of recovery.

Valuable items (passports, IDs) may be transferred to the airport police for safekeeping.

For in‑person help, visit the Information Counter in Terminal 1, which can direct you to the proper Lost & Found desk.
