CHICAGO (AP) On Jan. 1, an order went into effect requiring that every checked bag at

more than 400 of the nation's commercial airports be screened(扫描检查)for bombs and weapons.Sunday was expected to be the heaviest travel day since Jan. 1. Yet spot checks on Sunday at several of the nation's airports showed no major delays caused by the new security measures.At the international terminal for Northwest Airlines at John F. Kennedy International Airport in New York, passengers waited up to 30 minutes longer than usual. Their bags were sent through giant screening machines and workers tore open taped boxes and searched through their contents before closing them up again.Most travelers simply accepted stricter screening developed since the terrorist(恐怖分子)attacks on Sept. 11, 2001, before which only 5 percent of the roughly 2 million bags checked each day were screened for bombs.The U.S. government has put an additional 23,000 people into airports to carry out the new order.Sonny Salgatar, a 23-year-old college student flying home to San Diego from Chicago, was told by an airport officer after the first pass that one of his bags was "hot", meaning there was something he couldn't identify and he wanted to open the bag for an inspection.The "hot" item turned out to be Salgatar's clothing iron."Listen, anything they want to do for security is OK for me," Salgatar said.
