More than 90 percent of airline passengers say technology helps them when travelling but using a smartphone for travel services has yet to go main stream. This is despite the finding that three quarters of passengers carry a smartphone according to results of the 2013 SITA/Air Transport World Passenger IT Trends Survey released today. The survey conducted at six leading airports around the world paints a picture of tech-savvy passengers who are equipped to use the latest mobile travel services but are cautious about doing so. At 76%, the proportion of passengers carrying smartphones outstrips the global average of 40% in the general population.
