Travel Weekly's 2013 Consumer Trends Survey underscores the surge in popularity of mobile devices: In 2012, 25% of respondents reported using a smartphone or tablet for purchasing travel online at any point in the previous 12 months. That number grew to 30% in this year's survey, representing a 20% increase. Just as importantly, the survey revealed that the percentage of the population using mobile devices for buying travel has grown beyond typical early adopters. While mobile users last year were predominantly in the 21-to-34 age group, over the past 12 months, older travelers have caught on. Among ages 35 to 54, use of mobile devices to make a travel purchase climbed from 23% to 33%. An even bigger growth was reported among the 55-and-over crowd, where use of tablets or smartphones for travel purchases jumped from 14% last year to 24% this year. What's more, Henry Harteveldt, industry analyst for Hudson Crossing, predicts that those percentages will skyrocket in all demographic groups in the coming year. Get the full story at Travel Weekly
