Lost & Found

Pro Tip
GPI holds unclaimed items for only 60 days before they're discarded or donated, so file a report through the online Boomerang lost-and-found form at iflyglacier.com/lostfound/ or call right away. Note that lost, delayed, or damaged checked baggage is handled exclusively by your airline, not the airport, and keys lost in the parking lots may be held separately by Republic Parking (406-257-6868).
How long does GPI 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 GPI?
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 GPI?
Yes — GPI has an online lost item report form. Filing online is recommended as written claims are typically processed faster than phone reports alone.
