British Airways (BA) says it has become the first UK airline to introduce automated biometric technology throughout the airport – with the launch of self-service boarding gates. Following a successful trial in June 2016, the first three boarding gates for UK domestic flights departing from Heathrow Terminal 5 are now open, and more than 4,000 customers have already benefited from the new technology.According to BA, the gates create a smoother journey for customers as they travel through the airport, with travellers scanning their own boarding pass when they arrive at the gate and then simply walking through to the aircraft.A digital facial scan of the customer is recorded when they travel through security, and when they arrive at the gate, their face is matched with this representation when they present their boarding pass – allowing them to board the aircraft.BA says: “Safety and security is at the core of the biometric facial recognition technology, and British Airways' equipment is more advanced than alternative systems currently used by other airlines and airports.”Three more British Airways self-boarding gates will open at each domestic departure stand each week until mid-June 2017, with a view to rolling out the scheme on international flights in the future.BA says the introduction of the new gates is part of wider investment into new technology that will enhance the experience its customers have during their time at the airport.British Airways has also opened self-service bag drop points at Gatwick and Heathrow, and later this year will introduce an improved, more streamlined connections area at T5. This week, The First Wing opened at T5 – an exclusive redesigned check-in area for premium customers, including a dedicated private security channel with direct lounge access for the first time.”Our customers have told us that they want the ability to simplify and speed up their journeys through the airport,” says Troy Warfield, British Airways' director of customer experience. “The addition of self-boarding gates, along with self-serve bag drop points, are just two of the ways in which we are investing in areas our customers value most.”
