Less onerous security for some at D.C. airports

Frequent fliers can soon keep their shoes on and leave laptops in their cases when going through security in Washington-area airports.

The Transportation Security Administration announced Wednesday the expansion of a new screening program to 28 major U.S. airports that allows some low-threat passengers to skip longer waits and go through a separate line at security checkpoints. Baltimore-Washington International Thurgood Marshall Airport, Ronald Reagan Washington National Airport and Washington Dulles International Airport are expected to be among those to adopt the new rules by the end of 2012.
