Instead of paper or mobile boarding pass, members have a more efficient option to use fingerprints as proof of identity to go aboard a plane. In the near future, it also will be possible to use fingerprints to check a bag.“Once we complete testing, customers throughout our domestic network could start seeing this capability in a matter of months – not years. Delta Air Lines really is delivering the future now,” said Gil West, Delta’s Senior Executive Vice President. SkyMiles members who want to use the new option, also need to be enrolled in CLEAR, an expedited security program.
