Adobe Digital Insight’s latest Travel Trends Report for 2017 draws from 16 billion visits to major U.S. travel, airline, hotel, car rentals, and online travel booking sites between January 2015 and March 2017. Spend by U.S. consumers for the summer travel season is expected to slow to 5.1% year-over-year growth (down -66% from last). Online bookings for flights are on par with last year, yet increased prices for both airfare and hotels cause a drag on sales. Consumers can still save by getting the best prices on domestic flights 125 days in advance, and hotels 33 days in advance.
