Boarding passes could someday become quaint relics for air travellers.
Delta Air Lines plans to let some passengers board with their fingerprints instead of a boarding pass, and JetBlue Airways plans to test facial-recognition check-in for a few flights beginning later this month.
The once-ubiquitous paper boarding pass is already shunned by many travellers who prefer to use mobile boarding passes on their phones. Now pilot programs could render those obsolete too, as airlines aim to increase convenience for customers, and government agencies look to increase security.
Delta recently started letting come members of its loyalty program use fingerprints as proof of their identity to enter the airline's lounge at Reagan Washington National Airport.
The airline says that it plans to expand the test at that airport to let members use fingerprints to check a bag and board a plane.
