Boarding pass fail: Have you shared a snap of YOURS on Instagram?

Along with sharing snaps of icy cold tipples and pre-holiday pints, more than a few of us are guilty of uploading a snap of our boarding pass before we ditch Ireland for sunnier climes.

Well, it looks like we could be unwittingly leading ourselves into a world of trouble if those snaps got into the wrong hands.

Honouring the pre-holiday ritual with a photo of your documentation should be a no-go according to experts with KrebsOnSecurity.

Strongly advising travellers against the practice, they said: “Two-dimensional barcodes and QR codes can hold a great deal of information."

According to a report in The Independent: "The codes printed on airline boarding passes may allow someone to discover more about you, your future travel plans, and your frequent flyer account.”

Stick with a pic of the pre-holiday pint from now on, ladies.
