St. Louis Airport Lost and Found

Lost something at St. Louis Lambert International Airport? Report it immediately — airport lost and found offices hold items for 30–90 days, but recovery rates drop sharply after the first 24 hours.

Items left at the security checkpoint are logged separately from general terminal lost & found. Report a missing item as soon as possible — recovery odds drop sharply after the first day, and TSA holds checkpoint items only for a limited period before donating or discarding them.

Note: items left in gate areas may also be held by the airline's gate staff — contact the airline directly for gate-area and on-board lost items.

What to do right now (step by step)

Check with the airline first — items left at gates or on the plane go to the airline, not the airport.
If lost in the terminal: call 314-890-1370 or go to Terminal 1, Airport Police Department, near Door 18.
If lost at the security checkpoint: call TSA at 1-866-289-9673 or file a claim online.
File an online claim if available — written claims are processed faster and create a searchable paper trail.
Check back in 24–48 hours — items are logged as they come in and may not appear in the system immediately.

Pro Tip

STL splits lost & found by where the item went missing: the Airport Police Department (314-890-1370) handles anything lost past security or in the terminal generally, while items left at the checkpoint itself go through TSA. Call during the 9am–4pm window — outside those hours, leave a detailed voicemail describing the item and your flight, and follow up the next business day.

Frequently asked questions

How long does STL airport keep lost items?

Most airports hold unclaimed items for 30–90 days before donating or auctioning them. File your claim as quickly as possible to maximize recovery chances.

What if I left something on the plane?

Items left on aircraft go to the airline, not the airport lost and found. Contact the airline directly — each airline has its own baggage service phone number and online claim process.

How do I report a lost item at the TSA checkpoint at STL?

Call TSA at 1-866-289-9673 or file a claim at tsa.gov/travel/customer-service. Items left at security checkpoints are held for 30 days.

Can I file a lost item report online for STL?

STL does not currently list a standalone online lost item report form. Call 314-890-1370 to file by phone or visit Terminal 1, Airport Police Department, near Door 18 in person.
