Delta Air Lines has deployed facial recognition technology to accelerate passenger clearance processes at Terminal 2 of Los Angeles International Airport in California, US.

The American airline has installed cameras at one gate, with plans to introduce more in the future.

In collaboration with various airlines and federal agencies, Los Angeles Airport piloted facial recognition technology last year.

US Customs and Border Protection (US CBP) tested the technology for a month.

US CBP released in a statement: “Although CBP has a very thorough and robust biographic vetting system, biometrics provides additional assurance and confirmation of identity.”

Delta Air Line’s latest implementation of facial recognition technology at Terminal 2 is permanent and will be extended to 13 of its 21 boarding gates.

The cameras take photographs of passengers as they pass through the gates and match them with photographs and names already stored in databases held by US CBP and other government agencies.

As soon as the facial data and other credentials is matched with stored data, the passenger is allowed to board their flights.

It is estimated that the facial recognition technology will save an average of nine minutes compared to traditional boarding, or two seconds for every passenger.

Delta spokeswoman Liz Savadelis said: “Maintaining the privacy and security of customer information is a responsibility Delta takes very seriously.”

In June, Delta revealed plans to deploy facial recognition cameras at 49 boarding gates at Hartsfield-Jackson Atlanta International Airport, Minneapolis-Saint Paul International Airport and Salt Lake City International Airport.
