The travel business consultancy and technology company Sojern aggregates enormous amounts of data on U.S. and international travel. They recently put together this data-packed infographic for their paying customers on 2013 U.S. travel trends based on first quarter 2013 . The graphic reveals some interesting information. It seems that 25% of U.S. travelers actually book within a week of travel. And, 57% of U.S. travel is still for business. No surprise to see that 95% of flyers are in coach.
