Summer is hot! And so is travel in Europe. Europeans will be doing a lot of traveling this summer — about 60% to destinations within Europe and 40% beyond. Based on analysis of nSight’s search and booking data aggregated from 5,000+ travel websites for travel dates between June 1- August 30, the travel behavior for regions within Europe are quite different. For example — Western Europe searches and books the most for U.S. destinations. And Eastern Europe tends to search and book more within Europe.
