eMarketer estimates that leisure and unmanaged business travelers in the UK will spend £18.44 billion ($29.27 billion) this year on bookings made on desktop and mobile devices, up 11.8% over 2012. We expect growth rates to slow throughout the forecast period, with a 5.3% increase in digital travel sales expected for 2017, when the total spent will reach £24.68 billion ($39.17 billion). This year, eMarketer estimates, travel sales will account for 29.5% of the overall UK business-to-consumer (B2C) ecommerce market, which includes both travel and retail sales. Travel will lose a few points of share to retail in the coming years, taking a projected 27.5% of the B2C ecommerce market in 2017. Digital travel sales are propelled by a large market of researchers and bookers looking for travel products and services on the web. eMarketer estimates 25.8 million people in the UK will research travel online at some point during 2013, whether they end up booking a trip or not. That’s nearly two-thirds of the internet population in the country. Get the full story at eMarketer
