Fresh off visiting one of his daughters in Colorado and on his way to see another in Chicago, Oliver Coolidge got his first up-close look at Denver International Airport‘s new West Security Checkpoint last month. The state-of-the-art screening area opened in the northwest corner of the airport’s Level 6 in early February, replacing the smaller, dated North Security Checkpoint on the floor below it. Asked for his review after passing through one of the checkpoint’s 17 tech-laden screening lanes, the 74-year-old Coolidge took a neutral position. “I don’t know if it’s better or not,” said Coolidge, a TSA PreCheck customer.
