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 208-972-8400, option 0 (Airport Administration main line — no separate publicly listed Lost & Found extension; ask to be connected to Airport Operations) or go to Airport Operations office, third floor of the main terminal building (per secondary sources; the official site directs travelers to the online form rather than listing a walk-in address).
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

Boise Airport holds found items for only 14 days before donating them, so file the online ChargerBack claim form immediately after realizing something is missing. Items left on an aircraft or in checked baggage should go through your airline directly (Alaska, Allegiant, American, Delta, Southwest, and United all have counters/baggage service desks in the terminal), and items left in a rental car should be reported straight to the rental company.

Frequently asked questions

How long does BOI 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 BOI?

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 BOI?

Yes — BOI has an online lost item report form. Filing online is recommended as written claims are typically processed faster than phone reports alone.
