Two things of note. The Secure Flight rule does NOT state that if you are not booked 3 days before that you cannot fly. In fact, the rule summary includes the following:
Although
approximately 99% of passenger travel
reservations would be finalized within
24 hours of the departure of any flight,
24 hours would not provide TSA with
sufficient time to adequately screen 2.4
million passengers and, when
necessary, coordinate operational
responses in the event of identification... All the rule really does is give government agencies ample time to respond to a watch list match that they were running anyways. The only privacy you give up is the time frame in which Uncle Sam knows of your itinerary. If the government was really interested in you, they would track your flight purchase from your credit card and know the instant you bought them. This doesn't really affect any of us unless we happen to be one of those 500,000 to 750,000 people who managed to find themselves on the watch list.
Obviously this is a bullshit attention grabbing rule. What terrorist in his or her right mind would knowingly book their suicide tickets in advance now? Granted this assumes that terrorists have 'right minds'...
And Fox has a conservative bias.
