What Hacker News says?
The barcodes are not encrypted. Generating a modified one would be pretty simple. http://shaun.net/2011/05/whats-contained-in-a-boarding-pass-... http://www.flickr.com/photos/kalleboo/6197243200/ [Update: iNate2000 says cell phone ones are signed. That would make modifying it much more difficult. It also implies printed ones are not signed, which makes that form the the attack vector.]
