We’ve been informed ― time and time again ― that we should never post a photograph of our boarding pass online when we travel.

Lately, travel blogger Steve Hui found his Fb friend posted a photo in their boarding pass before a trip. He decided to perform an experiment to see how much information he could glean from the boarding pass photo, which comprised reservation reference number and the voyager’s name from Delta.

Hui confesses his discoveries were merely the start of what a hacker can discover with a flyer’s boarding pass information.

Turns out just several digits that are observable can ruin a trip.

If he’d wanted to, Hui wrote on news.com.au, he could’ve changed the voyager’s seats, swapped meals, canceled legs of their trip or ended the trip entirely.

“Technically, from there you could easily… hack into someone’s frequent flyer account,” Hui told HuffPost. And from there, there’s complete excursion history, a number of points, and maybe you are able to redeem things such as gift cards.” and flights


And boarding pass bar codes aren’t secure, either.

“Information encoded into the… bar code on each boarding pass comprises mainly the same information which is clearly printed on the document: title, flight numbers, boarding and destination towns, instances, airport, gate, seat, regular traveler account quantity,” Davidson advised HuffPost.

In short, the finest picture is no picture at all.

“ The greatest threat in publishing a boarding pass on media is that it’s an obvious sign that the individual will not be home at a specific time,” Davidson stated. “That… is like leaving the front entrance not only unlocked, but thrown wide open.”

You may think you’re following safe methods by covering up numbers or the name on your pass. But actually, the most useful practice is to not post a photo of your boarding pass whatsoever. Doing so is like telling the entire world you’re out of the city and off your guard.
