As biometrics use in airports continues to increase rapidly, Delta has addressed consumers with an article on ‘What you should know about biometrics and Delta.’ 

"In a post COVID-world, touchless technology has never been more important. And while most customers have been at home since the COVID-19 pandemic began, a lot has changed at Delta to transform cleanliness and safety so they can feel more confident when they return to travel. One thing that’s remained constant is Delta’s continued commitment to investing in technology that enhances the customer travel experience. Now more than ever we know touchless technology is what our customers want and need to feel safe. Currently, customers traveling direct to an international destination can choose to use facial recognition technology to board flights in Atlanta, Minneapolis, Salt Lake City, New York JFK, Detroit, Los Angeles, Portland and Boston," noted Delta.
