There is truth to this. I have a friend who has travel plans over Thanksgiving. He is a police officer, btw. (Not an hysterical woman, as I keep hearing from certain individuals). He told me IF it's a terrorist incident, he will not fly; however, if it were a mechanical error, he will stick will his present travel arrangements and fly.
I'm approaching my situation the same way. Whether or not I rebook my flight rests on the outcome (and credibility) of the results of the investigation.
