Booking.com continues to see strong growth in mobile bookings with the total transaction value of mobile accommodation bookings more than doubling from over $3 billion in 2012 to over $8 billion in 2013. Looking back at the 2011 figure where Booking.com saw $1 billion in mobile bookings, it is clear that mobile accommodation booking continues to grow rapidly year on year.

"Booking.com has more than 425,000 accommodations across 25 different accommodation types, bookable via all devices," says Booking.com CMO, Paul Hennessy. "We're seeing a shift in consumer behaviour from simply booking last minute accommodations on mobile devices to planning, researching, booking and utilizing post booking functionality on our mobile platforms."

The online mobile hotel and accommodation bookings referred to above were made through the Booking.com family of hotel booking apps including native apps for iOS and Android, and through Booking.com's mobile websites.
