WestJet, a Canadian airline lost a seven-year-old boy who was travelling alone as an 'unaccompanied minor' a few days ago; the lad was on his route to visit his grandmother on Vancouver Island. Despite wearing a tag around his neck that identified him to airline employees as an unaccompanied minor, he was not escorted off the flight at the airport in Comox, British Columbia. Nothing actually happened to the boy who was met at the airport; it was just that he was not escorted. It's been suggested that it would have been safer to ship the boy FedEx.
Maybe there's a business here - KidEx?
