The growing number of travelers picking up their mobile devices rather than sitting at their desktop computers to book air travel or a hotel is a reality becoming more common each and every day.

The percentage of mobile travel bookings have grown for the past six consecutive quarters while desktop bookings continue on a downward slope. The pace of mobile’s rise, of course, varies region by region and new data show travelers from the U.S. and countries in the Asia-Pacific region are converting on mobile more than those in Europe, the Middle East and Africa.

From online travel agencies versus hotels’ mobile websites to mobile app versus mobile web, Criteo, an ad tech company, pulled data from more than 500 travel companies around the world what their growth rates look like for these cases and more. The data span from early 2014 to the present and includes analysis from more than one billion travel bookings worldwide.
