The one thing you should never do with your boarding pass

We're all familiar with the various stages of planning a holiday.

First you book your flights and your accommodation, then you spend weeks getting excited before hitting a slump on your last night in Ireland because you realise you have to pack. Then you get excited again and head for the airport.

You make sure you've got everything you need, money, passport, boarding pass... Then you do what every young person in their right mind would do. You brag about it on social media.

Usually this will involve a picture of your pint in the airport bar alongside your boarding pass as proof that, yes, you are going on holiday.

But it turns out that publicly posting a picture of your boarding pass is a big mistake.

A post on a security blog says:

"Two-dimensional barcodes and QR codes can hold a great deal of information, and the codes printed on airline boarding passes may allow someone to discover more about you, your future travel plans, and your frequent flyer account."

This is bad news for the thousands of people who have already posted pictures to Instagram that are hashtagged 'boarding pass', let alone the people who have done the same without tagging.

So the next time you're in the airport, stick to a selfie.
