In 2018, Microsoft Travel rebuilt the company's travel portal around a chatbot-driven, personalized experience based on Microsoft's years of work to develop a group of personas for travelers and thus personalize communications and offers to each traveler. Meanwhile, the company's Roadmap and Tripism users have increased to 35,000 each. Roadmap makes traveler friendly apps customized to each corporate travel program. Tripism, whose Microsoft users numbered only 10,000 users in October 2017, makes recommendations for travelers based on peers' experiences, as well as Microsoft office locations, preferred hotel suppliers and Dinova network restaurants. Tripism is now being leveraged for suppliers to provide updated Covid-19 status and cleaning protocols directly to employees. Almost half Microsoft's U.S.-booked travel in 2019 was domestic. Nearly all of the U.S.-booked tickets, 95 percent, went through approved online tools, and 90 percent of those required no agent assistance. Microsoft made no changes last year to its travel policy, which is global and only two pages long.
