(Portland, OR) -- Airports in Portland and Eugene set records last year for the most guns found at TSA checkpoints. Portland had 78 guns and Eugene had 10. A total of 108 guns were found at Oregon's four airports with TSA security screening. Passengers can face criminal charges and hefty fines for bringing a gun through security in carry-on baggage. Guns can be brought onto a plane only if they're unloaded, packed in a locked, hard-sided case and placed in checked baggage. Replica guns also need to go in checked bags. Passengers with guns need to notify the carrier when checking in.
