This Is Why You Should Never Throw Away Your Boarding Pass
Travel has a way of loading you down with scraps of paper. Luggage claim tickets, subway passes, bus tickets stubs, reservation confirmations, and old boarding passes.
While you might not think twice about tossing your spent boarding pass, there’s actually a very good security reason to hold on to it.
Security bloggers have recently pointed out that it’s now possible for someone to discover a lot about you from your boarding card. By using the barcode on the paper slip, the right person could figure out things like your address (or at least your billing address), your past travels and future travel plans with that airline, and your frequent flier account details.
Furthermore, nefarious persons could potentially log into airline websites using a code printed right on the pass and do things like change your seat, cancel future flights and even reset your account info.
Of course, it’s highly unlikely that a stranger would go so far as to change your seating assignment on a flight or cancel your travel plans. However, holding on your boarding pass until you’re home and running it through a shredder might be a good idea anyway.
