They scanned his boarding pass and everything, yet his one hour flight turned into a three hour flight to the wrong destination! 

Fernando Giron is used to the one hour flight from Sacramento to LA, as he's done it several times. According to WNEM, he ended up on the wrong plane and eventually in the wrong city - Dallas, TX which is 1,400 miles away from his desired destination. Apparently the gate for LA and Dallas are right next to each other in the Sacramento airport, and were boarding at the same time, so he got confused. The question he asks is how no one corrected him. He feels that if it's that easy to end up on the wrong flight, it could be a threat to National Security.
