According to the New York Times, it is "estimated that the government could save $1 billion over five years by using private screeners at the nation’s 35 largest airports." However, another article out today indicates that there are some contraints on reducing costs through private screeners: However, the SPP model allows for little variance in screening operations at SPP airports. For example, in accordance with ATSA, private screeners must meet the same standards and requirements for hiring and training that apply to federal screeners, abide by the same standard operating procedures, and be provided compensation and benefits at a level not less than their federal counterparts. If they have to meet the same standards and receive similar pay & benefits, what's left to reduce? They must be getting rid of the thousands standing around, i.e. better utilization of the human resources that they're paying to work at the checkpoints.
