Britain's Luton Airport has responded to increasing demand by installing five new biometric ePassport gates.The facial recognition-enabled gates bring the total number at Luton to 15.The airport recorded a 13 per cent increase in passengers in November, its 32nd consecutive month of passenger growth, reports Business Traveller.The airport says it is currently the only London airport without an "express-style" rail service offering at least four trains per hour to central London, and has called on the government to change this "through the upcoming East Midlands rail refranchising process".This would be separate to the £200 million planned rail link between Luton Airport Parkway station and the terminal.Commenting on the news Nick Barton, CEO of London Luton Airport, said:"We're working hard to transform the airport with our £110million investment programme. Working with Border Force to introduce more automated e-passport gates is a great indicator of how we're aiming to make our passengers' journeys as quick and simple as possible."With the redevelopment making rapid progress on-site, we're also looking to drive improvements in transport links to the airport. Introducing four fast trains per hour through the new East Midlands franchise would benefit passengers, the local community and fare box revenues at no cost to government.
