When the second copy of a boarding pass scans, you double check with that person, maybe there&amp;#x27;s a good reason (scanned pass, but had to leave the line for some reason). If it doesn&amp;#x27;t make sense, ask the flight attendants to audit seats. Also summon security.&lt;p&gt;The suspect is on the plane and can&amp;#x27;t easily leave, presuming the real passenger is the one who presents second.</text><parent_chain><item><author>waltbosz</author><text>I&amp;#x27;ve thought up this exact scam before while standing in line to board a flight and watching people being cavalier with their boarding passes.&lt;p&gt;I suspect others have successfully pulled it off before and this guy was the first to get caught because of a full flight.&lt;p&gt;My back seat driver solution: have cameras that takes a picture of the person presenting the boarding pass, the shutter is triggered by the pass scanner. If a pass is scanned twice, bring up the photo of the person who scanned it the first time and grab them. But it&amp;#x27;s a whole lot of tech to solve a problem that probably rarely happens.</text></item></parent_chain></comment><story><title>Man creatively sneaks onto Delta flight, but gets caught</title><url>https://onemileatatime.com/news/man-creatively-sneaks-onto-delta-flight/</url></story>
