As part of a trial of the use of biometric technology for international flights, customers who sign up to take part will be invited to scan their face, passport and boarding pass on their smartphone or tablet ahead of travel.

When participants arrive at the airport, Smart Bio-Pod cameras, provided by Amadeus Biometric Solutions, will verify their identity in under three seconds, allowing them to keep their passport in their pocket until they reach their destination.

David Breeze, operations transformation manager for British Airways, said: "Not only is this the first time that our customers have been able to register their biometric information at home, but it’s the first time they can use it for British Airways international flights.

"This is a secure and efficient tool that makes for a smarter and smoother airport experience, which will reduce the time it takes us to board aircraft."

The trial will run for six months on British Airways flights to Malaga. Customers who opt in will be invited to make use of the fast-track security lane and will receive complimentary priority boarding.

If the trial is successful, it’s expected to be extended to more international flights.
