Air travel 'without your passport leaving your pocket'

New technologies are helping to tackle one of the great scourges of air travel - airport queues. Queues to check-in and drop your bags, at security, at passport control and finally queues at your boarding gate. Air travel can be a frustrating business, even if these queues are largely a result of airports trying to ensure our safety. And as more of us fly - 4.4 billion passengers are forecast to take to the skies in 2018 - airports are being pushed to their limits. So the industry is hoping technology can streamline the process, with increasing use of biometrics such as facial recognition - and not just at passport control.
