Notably, the single global travel policy now limits business class to flights of eight hours or more, up from six hours. Then, this year, DowDuPont split into three companies. The materials science division, which handles chemical commodities, became Dow; the agricultural chemicals division became Corteva and the specialty chemicals will remain as DuPont. The company's U.S.-booked air volume increased 13 percent in 2018. Of that volume, 55 percent is for travel outside the U.S. Of the U.S.-booked air tickets, two-thirds went through approved online tools, but 45 percent required agent assistance. The company's U.S.-booked air spend is expected to fall back to the 2017 level of $75 million in 2019.
