The airline are allowing their Delta SkyMiles Members who are enrolled in CLEAR to use biometrics to check in rather than a paper or mobile ticket if they are flying from Reagan Washington National Airport.
Later this summer, Delta's DCA biometric boarding pass will also allow members to use their fingerprint to check in a bag.
Delta has been able to launch this by partnering with CLEAR and they are currently testing how the systems work together in order to create a uniformed experience for the customer.
Gil West, Delta's Senior Executive Vice President & COO, said: "The truly exciting piece of what Delta is doing, is how scalable this experience is in part due to our partnership with CLEAR. Once we complete testing, customers throughout our domestic network could start seeing this capability in a matter of months - not years. Delta really is delivering the future now.
"Customer and employee feedback has been extremely encouraging throughout our Delta Sky Club test and we expect that enthusiasm to continue with the boarding experience. It's a win-win program.
"Biometric verification has a higher level of accuracy than paper boarding passes and gives agents more time to assist customers with seat changes and other skilled tasks instead of having to scan individual tickets - and customers have less to keep track of as they travel through the airport."
It is not the only technology Delta has launched to make their customers' experiences better. Over the past year, Delta has launched a biometric-based self-service bag drop, realtime bag tracking and even a groundbreaking app that can help Delta pilots avoid turbulence, making for a more comfortable flight.
