L-PAS Online Instructions.

The airport lost and found receives items lost in the airport areas. If you have lost an item on an aircraft or in a rental car, please contact the airline or rental company directly.
Items received are retained for thirty days and any unclaimed items are auctioned or donated.
This system only lists items that are considered low-value. This includes keys, clothing, canes, hats, glasses, and pillows. To check on other items that may have been lost at the airport, call us 24 hours at (813) 554-1414 or send us an inquiry at http://www.tampaairport.com/lost-and-found .
Use the filter feature which will search by keyword and date range. To use the filters, click on the icon as shown here.

Once you find the item, click Claim Item and fill out the claim form. We will contact you as soon as possible to arrange for pickup of the item.
