One of today's national newspapers has highlighted the risks of posting pictures of airline boarding cards on sites such as Instagram.
Not being a techie please bear with me in explaining the problem. Most boarding cards now display a bar code. By "hacking" into that bar code, personal details can be obtained about the passenger, including membership of frequent flyer programmes. It was suggested that the person who recently spent three weeks in airport lounges gained access by doing this.
Could it be the same people who posted their travel details on Facebook then wondered why they had been burgled......
