For the first time since Sept. 11, 2001, a major international airport is opening its terminals to non-passengers without special permission. Starting Sept.5, visitors to Pittsburgh International will be able to access the secure side of the airport by obtaining a “myPITpass” from an airport kiosk, which will require scanning a photo ID to run the visitor’s name against a TSA no-fly list.
