It all started in 2010 with the launch of HotelTonight. Since then there have been multiple entrants and OTA majors like Booking.com, Orbitz, Priceline, HRS and Expedia are making investments in this segment. For example, Expedia has been aggressively building its presence on mobile to meet its customers changing needs and 70% of its travel booking comes from last-minute bookings. So what really is last minute? In the hospitality industry, bookings windows of up to seven days in advance are known as last-minute booking. Within this there are three categories- seven days or less, three days or less and same-day. Same-day booking are done on the day guests wants to stay. Mobile applications like HotelTonight allow travelers to book a room for the same day. PhoCusWright reports that overall mobile search and booking volume is growing rapidly with gross travel bookings via mobile (phones and tablets) accounting for 27% in the US, up from just 5% in 2012. In UK, 1 in every 3 Britons book on the same day. The trend is more or less same in Asia Pacific as well, with 70% of mobile booking coming for same day stays. Get the full story at eRevMax
