This isn't really miles-related but we've spent a fair amount of time disucssing the topic on this forum anyway, so here goes:

United States (Country threat level - 3): Reports emerged today that
the U.S. Transportation Security Administration (TSA) will end secondary
passenger checks at airport gates. According to a TSA spokeswoman, the
primary checkpoints will be staffed with sufficiently trained
personnel, making the secondary screening unnecessary. Some passengers and
airline officials had complained that the secondary screenings were
redundant and overly intrusive. Reports did not indicate when the new policy
goes into effect.
