File a Lost Property Report

It will ask for your contact information* as well as other details to help identify your lost property. If you lost your item on the plane, please contact your airline directly. 

SEA's Lost and Found Office does not charge to file a lost property report. There has been an increase in unverified third-party websites charging a fee to retrieve a lost item; please only file lost property reports on this site.


Where do I file a report?

Only file a lost property report through SEA Airport's Lost and Found Office. The report will ask for contact information, the approximate location/date in which you lost the item and a description of what you lost.

I left my item(s) on my flight, who should I contact?

Please contact your airline directly to file a lost item report through your airline carrier. You can view a list of airlines' contact information at SEA Airport here.

I left my item at a TSA security checkpoint, what should I do?

Lost and Found receives items left at security checkpoints the following business day. Click on the New Report link to file a lost property report. Our Lost and Found software solution will compare specific criteria from lost property reports with found property that has been registered in our software for matching purposes. TSA does not deliver confiscated items to the Lost and Found.

I found something at SEA Airport, what do I do?

Turn in the property to SEA Airport Lost and Found as soon as possible to give the owner a better chance of reclaiming their property. We do not accept reports for found items and cannot reunite owners with their property without a detailed description and the property in our possession. If after hours, use the phone outside the lost and found window to report the found item. 

How does Lost and Found find owners of found items?

SEA Airport uses a Lost and Found software solution that assists in finding the owners of lost property and researches items for identifying information and characteristics. Once a property has been matched with the owner, email notification or phone call will be sent to the owner and they will be given restoration options.

How will I claim my property if I’m not in SEA Airport?

SEA Airport’s Lost and Found provides FedEx shipping options through the online lost property reporting system, which is Payment Card Industry Data Security Standard (PCI DSS) compliant.  You may also arrange to have someone claim your item on your behalf.
