A year ago Lufthansa became the 19th airline set up with TSA PreCheck. They joined Air Canada, Etihad, Aeromexico and WestJet as the first non-US airlines set up with PreCheck. And with that the massive US data-sharing, surveillance and passenger-convenience program had gone global.
Now 5 more airlines have joined: ANA, Cathay Pacific, Korean Air, Finnair and Contour Airlines.
