World: What will airports of the future look like?

Passengers' baggage is collected by robots, they relax in a luxurious waiting area complete with an indoor garden before getting a face scan and swiftly passing through security and immigration - this could be the airport of the future. It's a vision that planners hope will become reality as new technology is rolled out, transforming the exhausting experience of getting stuck in lengthy queues in ageing, overcrowded terminals into something far more pleasant. The Asia-Pacific has been leading the way but faces fierce competition from the Middle East as major hubs compete to attract the growing number of long-haul travellers who can choose how to route their journey. The regions "are the two leading pockets of technology growth because they are really competing to be the global hubs for air transportation," said Seth Young, director of the Center for Aviation Studies at Ohio State University. "If I'm going to fly from New York to Bangalore, do I transfer through Abu Dhabi or Dubai or do I transfer through Hong Kong? That's a huge, huge market." But the changes also represent major challenges that could upend decades-old business models at major airports, with analysts warning operators may face a hit to their revenues to the tune of billions of dollars. Facial scanning in particular is generating a lot of buzz. Changi, regarded as among the world's best airports, is set to roll out this biometric technology at a new terminal to open later this year.<br/>
