About two-thirds of its travel spending was for international trips. During 2016, Bayer conducted an RFP for car rental and switched to Hertz during the second quarter of 2017. The company also switched from individual bill, individual pay to Citi's CombiPay, under which expense reports are approved and then the system pays Citi on travelers' behalf. Those who do not submit expenses in a timely manner will be subject to Citi late fees. In 2016, the company streamlined its travel policy and in 2017 has made only minor adjustments. While it has a single U.S. travel policy, it does not have single global travel policy. In 2016, 72 percent of Bayer's U.S. air tickets were booked through its Concur online booking tool, and half of those were made without agent intervention. Outside the U.S., the company's primary booking tool was Onesto.
