Spending on airport security climbed to $19.1 billion last year, according to Frost & Sullivan's Global Airport Security Market Assessment. The firm predicts spending will soar 137.8% to $45.43 billion by 2018. "High threat perceptions of criminal or terrorist attacks will continue to boost investment in airport security," Anthony Leather, a Frost & Sullivan research analyst, said. "Regional and global legislation is constantly amended and updated in an attempt to address any criminal or terrorist activity. This has compelled airport operators worldwide to continually update the latest security procedures and technology solutions."
