A.I. is about to make the hassle of air travel a thing of the past

Artificial intelligence appears set to revolutionize the air travel experience for passengers -- and that could happen in just a matter of years, according to industry experts. Airports around the world already employ advanced technology such as biometrics, which authenticates travelers' identities based on physical attributes like fingerprints. But the next decade or so could herald a new era for air travel, experts say. For one, security clearances as we know them could become a thing of the past. Travelers will no longer need to produce any identifying documents at airports, Paul Griffiths, CEO of Dubai Airports, told CNBC.
